What should I do?
If you think you have this condition, you should call an ambulance or go to the hospital immediately.
How is it diagnosed?
Your doctor will ask questions about the symptoms that you are experiencing, such as delusions or hallucinations. They may need to refer you to a mental health specialist for further assessment and treatment. Part of the assessment involves evaluating the risk of harm to yourself or others. If there are concerns about this, then you may require hospital admission for urgent treatment.
What is the treatment?
Psychotic disorders are usually treated with antipsychotic medication.
Your doctor may also refer you for psychological treatment such as cognitive behavioural therapy and social support can also help manage the symptoms.
Psychosis is a medical word used to describe mental health problems that stop the person from thinking clearly, telling the difference between reality and their imagination, and acting in a normal way.
The two main symptoms of psychosis are:
- hallucinations – where a person hears, sees (and in some cases smells) things that are not really there; a common hallucination is when people hear voices in their head
- delusions – where a person believes things that, when examined rationally, are obviously untrue; such as believing that your next door neighbour is secretly planning to kill you
The combination of hallucinations and delusional thinking can cause an often severe disruption to perception, thinking, emotion and behaviour.
Experiencing symptoms of psychosis is often referred to as having a psychotic episode.
Read more about the symptoms of psychosis.
Psychosis is not a condition in itself – it is triggered by other conditions.
Sometimes it is possible to identify the cause of psychosis as a specific mental health condition such as:
- schizophrenia – a condition where people may have repeated episodes of psychosis
- bipolar disorder – a condition where people have periods of depression at times and at other times have periods of feeling energetic, impulsive and happy (manic)
The length of time that someone will experience a psychotic episode, will depend on underlying causes. Drug- or alcohol-induced psychosis may only last a few days.
However, psychosis that results from schizophrenia or bipolar disorder may last indefinitely unless treated.
Read more about the causes of psychosis.
Treatment for psychosis involves using a combination of:
- antipsychotic medicines, which can help relieve symptoms of psychosis
- psychological therapies, which can help address the underlying cause of the psychosis – for example the talking therapy cognitive behavioural therapyhas proved successful in helping people with schizophrenia
- social support – help to support the person with psychosis with social needs, such as education, employment or accommodation
Some people may only need to take antipsychotic medicines on a short-term basis. Other people may need them for months or, in some cases, years to prevent symptoms reoccurring.
In severe cases a person may need to be admitted to hospital or a secure psychiatric unit.
Read more about the treatment of psychosis.
Getting help for others
People with psychosis often have what is known as a lack of insight, meaning they are unaware they are thinking and acting strangely.
Due to their lack of insight, it is often down to friends, relatives or carers of people affected by psychosis to seek help for them.
If you are concerned that someone you know may be affected by psychosis you could contact their social worker or community mental health nurse if they have previously been diagnosed with a mental health condition.
If you think the person’s symptoms are placing them at possible risk of harm then you can:
- take the person to the nearest accident and emergency department, if they agree
- call their doctor or local out of hours doctor
- call for an ambulance
See diagnosing psychosis for more information on how get help for others.
People with a history of psychosis are much more likely to have drug and/or alcohol misuse problems. This may be because the use of these substances can provide short-term relief from symptoms (though they usually make symptoms worse in the long-term).
People with psychosis also have a higher risk of suicide than the population at large. It is estimated that one in five people with psychosis will attempt suicide at some point in their life and one in 25 people with psychosis will kill themselves.
Also, side effects can occur if taking antipsychotics on a long-term basis. A common side effect is weight gain, and in rare cases, type 2 diabetes.
Read more about the complications of psychosis.
Who is affected
Psychosis is more common than most people realise.
Another study estimated that around one in 100 people have at least one episode of psychosis at some point during their life.
Most cases of psychosis first develop during the older teenage years (15 or above) or during adulthood. Cases affecting children under the age of 15 are rare, accounting for only one in every 500 cases.
There are four main symptoms associated with a psychotic episode:
- confused and disturbed thoughts
- a lack of insight and self-awareness
These are outlined in more detail below.
A hallucination is when you perceive something that does not exist in reality. Hallucinations can occur in all five of your senses:
- sight – someone with psychosis may see colours and shapes, or imaginary people or animals
- sounds – someone with psychosis may hear voices that are angry, unpleasant or sarcastic
- touch – a common psychotic hallucination is that insects are crawling on the skin
- smell – usually a strange or unpleasant smell
- taste – some people with psychosis have complained of having a constant unpleasant taste in their mouth
A delusion is where you have an unshakeable belief in something implausible, bizarre or obviously untrue. Two examples of psychotic delusions are:
- paranoid delusion
- delusions of grandeur
These are described below.
A person with psychosis will often believe an individual or organisation is making plans to hurt or kill them. This can lead to unusual behaviour. For example, a person with psychosis may refuse to be in the same room as a mobile phone because they believe they are mind-control devices.
Delusions of grandeur
A person with psychosis may have delusions of grandeur where they believe they have some imaginary power or authority. For example, they may think they are president of a country, or have the power to bring people back from the dead.
Confusion of thought
People with psychosis often have disturbed, confused and disrupted patterns of thought. Signs of this include that:
- their speech may be rapid and constant
- the content of their speech may appear random; for example, they may switch from one topic to another mid-sentence
- their train of thought may suddenly stop, resulting in an abrupt pause in conversation or activity
Lack of insight
People experiencing a psychotic episode are often totally unaware their behaviour is in any way strange, or their delusions or hallucinations could be imaginary.
They may be capable of recognising delusional or bizarre behaviour in others, but lack the self-awareness to recognise it in themselves. For example, a person with psychosis who is being treated in a psychiatric ward may complain that all of their fellow patients are mentally unwell while they are perfectly normal.
Postnatal psychosis, also called puerperal psychosis, is a severe form of postnatal depression (a type of depression some women experience after they have had a baby).
It is estimated that postnatal psychosis affects one or two women in every 1,000 who give birth, and most commonly occurs during the first few weeks after having a baby. Postnatal psychosis is more likely in women who already have a mental health condition, such as bipolar disorder or schizophrenia.
As well as symptoms of psychosis (see above), symptoms of postnatal psychosis can include:
- a high mood (mania) – for example, talking and thinking too much or too quickly
- a low mood – for example, depression, lack of energy, loss of appetite and trouble sleeping
Postnatal psychosis is regarded as an emergency. If you are concerned someone you know may have developed postnatal psychosis contact your doctor immediately. If this is not possible call your local out-of-hours service.
If you think there is a danger of imminent harm you can call:
- your local Emergency services
- Call for an ambulance
The causes of psychosis have three main classifications:
- psychosis caused by psychological (mental) conditions
- psychosis caused by general medical conditions
- psychosis caused by substances, such as alcohol or drugs
These three classifications are described in more detail below.
The following conditions have been known to trigger psychotic episodes in some people:
- schizophrenia – a chronic (long-term) mental health condition that causes hallucinations and delusions
- bipolar disorder – previously called manic depression, bipolar disorder affects your moods, which can swing from one extreme to another
- severe stress or anxiety
- severe depression – feelings of extreme sadness that last a long time (including postnatal depression, which some women experience after having a baby)
- lack of sleep
The underlying psychological cause will often influence the type of psychotic episode someone experiences. For example, a person with bipolar disorder is more likely to have delusions of grandeur, whereas someone with depression or schizophrenia is more likely to develop paranoid delusions (read more about the symptoms of psychosis).
General medical conditions
The following medical conditions have been known to trigger psychotic episodes in some people:
- HIV and AIDS – a virus that attacks the body's immune system (the body’s natural defence against illness and infection)
- malaria – a tropical disease spread by infected mosquitoes
- syphilis – a bacterial infection usually passed through sexual contact
- Alzheimer's disease – the most common form of dementia that causes a decline of mental abilities, such as memory and reasoning
- Parkinson's disease – a chronic condition that affects the way the brain co-ordinates body movements, including walking, talking and writing
- hypoglycaemia – an abnormally low level of sugar (glucose) in the blood
- lupus – a condition where your immune system attacks healthy tissue
- Lyme disease – a bacterial infection spread to humans by infected ticks
- multiple sclerosis – a condition of the central nervous system (the brain and spinal cord)
- brain tumour – a growth of cells in the brain that multiply in an abnormal and uncontrollable way
Alcohol and drug misuse can trigger a psychotic episode. A psychotic episode can also be triggered if you suddenly stop taking a drug or drinking alcohol after using for a long time. This is known as withdrawal.
You can also experience psychosis after drinking large amounts of alcohol or if you are high on drugs.
Drugs known to trigger psychotic episodes include:
- amphetamine (speed)
- methamphetamine (crystal meth)
- mephedrone (MCAT or miaow)
- MDMA (ecstasy)
- LSD (acid)
- psilocybins (magic mushrooms)
In rare situations, psychosis can also occur as a side effect of some types of medication, or as a result of an overdose of that medication.
One example is levodopa, a medication used to treat Parkinson's disease, but any medicine that acts on the brain can cause psychosis with an overdose.
Never stop taking a prescribed medication unless advised to do so by your doctor or another qualified healthcare professional responsible for your care. See your doctor if you are experiencing psychotic side effects because of taking a medication.
There has been a great deal of research looking at how psychosis affects the brain and conversely how changes in the brain can trigger symptoms of psychosis.
A summary of the research is provided below.
Research has revealed that during a psychotic episode several physical and biological changes occur in the brain.
The results of magnetic resonance imaging (MRI) scans have shown some people with a history of psychosis may have less grey matter than the average member of the general public. Grey matter is the part of the brain responsible for processing thoughts. MRI scans use a strong magnetic field and radio waves to take images of the inside of the body.
This research has led to scientists suggesting repeated episodes of psychosis may actually cause physical damage to the brain. However, further research is required to confirm this.
Alternatively, both the reduction of grey matter and a history of psychosis could both be symptoms of an underlying condition not yet identified.
Researchers also believe that dopamine plays an important role in psychosis.
Dopamine is a neurotransmitter, one of many chemicals the brain uses to transmit information from one brain cell to another. Dopamine is associated with how we feel something is significant, important or interesting.
In people with psychosis, it is thought levels of dopamine in their brain rise too high. The excess dopamine interrupts specific pathways of the brain responsible for some of its most important functions, such as:
- social behaviour
Disruption to these important brain functions may explain the symptoms of psychosis.
Evidence for the role of dopamine in psychosis comes from several sources, including brain scans, and the fact that medications known to reduce the effects of dopamine in the brain also reduce symptoms of psychosis. However, illegal drugs known to increase levels of dopamine in the brain, such as cannabis, cocaine and amphetamines, can trigger psychosis.
Visit your doctor if you are experiencing psychotic episodes. It is important to speak to your doctor as soon as possible because early treatment of psychosis usually has better long-term outcomes.
Visit your doctor
There is no test to positively diagnose psychosis. However, your doctor will look at your symptoms and rule out short-term causes, such as drug misuse.
Your doctor may ask questions to determine the cause of your psychosis. For example, you may be asked:
- whether you are taking any medication
- whether you have been taking illegal substances
- how your moods have been – for example, whether you have been depressed
- how you have been functioning day-to-day – for example, whether you are still working
- whether you have a family history of mental health conditions, such as schizophrenia
- about the details of your hallucinations, such as whether you have heard voices
- about the details of your delusions, such as whether you feel people are controlling you
- whether you have other symptoms
The evidence supporting the early treatment of psychosis means you are likely to be referred to a specialist urgently. This will either be during or after your first episode of psychosis. Who you are referred to will depend on services available in your local primary care trust (PCT). However, you may be referred to:
- a community mental health team – a team of different mental health professionals who provide support to people with complex mental health conditions
- a crisis resolution team – a team of different mental health professionals who treat people currently experiencing a psychotic episode, who would otherwise require hospitalisation
- an early intervention team – a team of mental health professionals who work with people who have experienced their first episode of psychosis
These teams are likely to include some or all of the following healthcare professionals:
- a psychologist – a healthcare professional who specialises in the assessment and treatment of mental health conditions
- a psychiatrist – a qualified medical doctor who has received further training in treating mental health conditions
- a community mental health nurse – a nurse with specialist training in mental health conditions
Your psychiatrist will carry out a full assessment to diagnose any underlying mental health condition that could be causing your symptoms. This will help when planning your treatment.
The lack of self-awareness associated with psychosis means people experiencing psychosis will not be able to recognise they are behaving strangely. They may be reluctant to visit their doctor if they believe there is nothing wrong with them, and you may need to get help for them.
Someone who has had psychotic episodes in the past may have been assigned a social worker (someone who works in social services), so try to contact them to express your concerns.
If someone is having a psychotic episode for the first time, it may be necessary for a friend, relative or someone else close to them to persuade them to visit their doctor. If someone is having a rapidly worsening psychotic episode, contact the duty psychiatrist at their nearest Emergency department.
If a person having a psychotic episode refuses to seek help, and is believed to present a risk to themselves or others, their nearest relative can request a psychological assessment is carried out. The social services department of your local authority will advise about this.
Treatment for psychosis involves a combination of antipsychotic medicines, psychological therapies and social support.
Your care team
Your treatment is likely to be co-ordinated by a team of mental health professionals working together. If this is your first psychotic episode, you may be referred to an early intervention team.
Early intervention teams
An early intervention team is a team of healthcare professionals set up specifically to work with people who have experienced their first episode of psychosis.
Some early intervention teams only focus on a certain age range, such as people who are 14 to 35 years old. Depending on what is necessary for your care, early intervention teams aim to provide:
- a full assessment of your symptoms
- prescriptions for medications
- psychological services
- social, occupational and educational interventions
Treatment for psychosis will vary depending on the underlying cause – for example, your treatment may be slightly different if you have been diagnosed with an underlying mental health condition as well.
- bipolar disorder is treated using a variety of medications, which could include antipsychotics to treat symptoms of mania; lithium and anticonvulsants to help stabilise mood on a long-term basis; and psychological therapy such as cognitive behavioural therapy (CBT)
- schizophrenia is usually treated using a combination of antipsychotic medication and social support, CBT or another form of psychotherapy called family therapy are often used
Psychosis related to drug or alcohol intoxication or withdrawal may only require a short course of antipsychotics or tranquilisers (which have a calming effect). Referral to an addiction counsellor may then be recommended.
Antipsychotic medicines, also known as neuroleptics, are usually recommended as the first treatment for psychosis. Antipsychotics work by blocking the effect of dopamine (a chemical that transmits messages in the brain). However, they are not suitable or effective for everyone as side effects can affect people differently.
In particular, antipsychotics will be monitored closely in people who also have:
- epilepsy – a condition that causes seizures or fits
- cardiovascular disease – conditions that affect the heart, blood vessels or circulation, such as heart disease
Antipsychotics can usually reduce feelings of anxiety or aggression within a few hours of use, but they may take several days or weeks to reduce other psychotic symptoms, such as hallucinations or delusional thoughts.
Antipsychotics can be taken orally (by mouth) or given as an injection. There are several 'slow release' antipsychotics, where you only need one injection every two to six weeks.
Depending on the underlying cause of your psychosis, you may only need to take antipsychotics until your psychosis subsides. However, if you have a condition such as schizophrenia or bipolar disorder, you may need to take antipsychotics on a long-term basis to prevent further episodes of psychosis.
Both typical and atypical antipsychotics have side effects, although not everyone will experience them and their severity will differ from person to person.
Side effects of typical antipsychotics can include:
- drowsiness – which may affect your ability to drive
- muscle twitches
- spasms – where your muscles shorten tightly and painfully
Side effects of both typical and atypical antipsychotics can include:
- blurred vision
- constipation – an inability to empty your bowels
- lack of sex drive
- dry mouth
See the patient information leaflet that comes with your medicine for a full list of possible side effects.
You should inform your doctor if your side effects are becoming particularly troublesome because there may be an alternative antipsychotic medicine you can take.
You should never stop taking medication prescribed for you unless advised to do so by a qualified healthcare professional responsible for your care. Suddenly stopping prescription medication could trigger a return (relapse) of your symptoms. When it is time for you to stop taking your medication it will be done gradually and under close observation.
Psychological treatment, such as counselling (a talking therapy), can help reduce the intensity and anxiety caused by psychosis. Some possible psychological treatments are discussed below.
Cognitive behavioural therapy
Cognitive behavioural therapy (CBT) for psychosis is based on an understanding of how people make sense of their experiences and why some people become distressed by them.
The aim of CBT is to identify unhelpful thinking patterns and emotions that may be causing your unwanted feelings and behaviours. It is then possible to learn to replace this thinking with more realistic and balanced thoughts.
A CBT therapist may encourage you to consider different ways of understanding what is happening to you. The aim is to help you achieve goals that are meaningful and important to you, such as reducing your distress, returning to work or university, or regaining a sense of control.
As family therapy is known to be an effective treatment for people with schizophrenia, it is also sometimes used to treat people who have experienced an episode of psychosis.
Family therapy is a way of helping both you and your family to cope better with your condition. After experiencing an episode of psychosis, you may rely on your family members for care and support. While most family members are happy to help, the stress of caring for somebody can place a strain on any family.
Family therapy involves a series of informal meetings that take place over a period of six months. Meetings may include:
- discussing information about your condition, such as what treatments are available, and how your condition might progress
- exploring ways of supporting someone with psychosis
- deciding how to solve practical problems caused by psychosis – for example, planning how to manage a future psychotic episode
If you are experiencing episodes of psychosis, a self-help group can be an additional source of support. You may benefit from being around others who have been through similar experiences. For example the mental health charity, Mind, has a network of local Mind associations and shops and you may be able to find a support group in your area.
Dealing with violence and aggression
Acts of violence and aggression are actually uncommon in people with psychosis. They are more likely to be victims of violence than perpetrators.
However, there may be time when your behaviour places yourself or others at risk of harm.
Mental health staff have received special training in dealing with aggressive behaviour.
If you fail to respond to requests to calm down, it may be necessary to hold you down without hurting you. This is known as a physical intervention. You may then be moved to a secluded room to calm down.
In some cases it may be necessary to give you a medication that will cause you to become very relaxed in a short space of time. This is known as rapid tranquillisation.
You will be asked to take the medication voluntarily but if you refuse you can be treated against your consent. This may involve giving you an injection of a tranquiliser.
It should be stressed that the methods described above are only ever used in extreme circumstances and are in no way a routine part of treating psychosis.
If there is a risk of future psychotic episodes occurring, and there are certain treatments you do not want to have, it is possible to pre-arrange a legally binding advance decision (previously known as an advance directive).
An advanced decision is a series of written instructions about what you would like your family or friends to do in the event you experience another psychotic episode. You may also want to include the contact details of your care team and social worker.
To create an advance decision, make your wishes clear in writing and have it signed by a witness. Include specific details about which treatments you do not want, and specific circumstances in which they may apply.
It is not always possible to prevent psychosis. For example, schizophrenia is caused by a combination of biological, psychological and environmental factors you may not be able to avoid.
However, you can prevent psychosis caused by substances by not taking illegal drugs.
Research has shown regular cannabis users are 40% more likely to develop a psychotic illness, such as schizophrenia, than people who do not use the drug.
Cannabis is known to increase levels of dopamine (a chemical that helps transmit messages) in your brain. Therefore, long-term cannabis use may cause permanent changes in your brain's chemistry that could lead to psychosis.
People who regularly use 'skunk' (the herbal type of cannabis specifically grown for its increased strength) are thought most at risk.
You should also avoid other recreational drugs, such as cocaine and ecstasy, because they also increase your risk of developing psychosis.
Stress and depression
Experiencing prolonged bouts of stress can sometimes trigger an episode of depression. Both stress and depression are major risk factors for psychosis.
The advice listed below may help reduce your stress levels, helping prevent depression and subsequent psychotic episodes.
- Use a problem-solving approach to deal with stress and worries
- Try to identify negative thoughts and change them to positive thoughts
- Assess your symptoms regularly and consult your doctor or counsellor if problems arise
- Take regular exercise. Exercise triggers the release of a mood-boosting brain chemical called serotonin
- Learn how to relax using relaxation exercises and tapes
- Practise yoga and meditation, or have a massage to help relieve tension and anxiety
- Join a self-help group to discuss your feelings and concerns. This can help you feel less isolated
- Avoid smoking, taking illegal drugs and drinking alcohol. These may make you feel better in the short-term, but will usually make you feel worse in the long-term
Read about depression and stress for more information about these conditions.
George and Josh's story
Smoking cannabis can lead to cannabis psychosis, causing you to lose touch with reality. Two men describe how it happened to them.
Sarah is 29 and had a significant psychotic episode in her early 20s, during which she was abducted and assaulted. She has since made a full recovery, worked in fundraising and events management and is now studying for a PhD.
“I had a phase of depression while I was at university but when I finished my degree that lifted. I got a very competitive publishing job, moved to London and had a cool social life.
“I was everyone’s best friend, had huge amounts of energy and was staying up later and later. Nobody really noticed anything, especially as my work wasn’t being affected, but mania was creeping up on me.
“After a row with my boyfriend at three in the morning I decided to head for my parents' house in Yorkshire. Outside my flat I got into what I assumed was a cab. It wasn’t.
“My memory of what happened over the next three days is very jumbled. My mind was running away with itself and I was developing full-blown psychosis. I became convinced that the man I was with was Stevie Wonder’s son and that he and I were secret agents on some sort of secret mission.
“I had developed something of an obsession with royalty as my mania emerged and kept thinking it was unfair that they had so much money and influence. I remember feeling very powerful and that my secret mission was to redistribute their wealth.
“This was my first experience of losing touch with reality. It was made all the more extraordinary because the man I was with seemed to be my closest ally at one moment, then the next he threatened me with a knife and raped me. My psychotic mind couldn’t make sense of what was going on.
“I was found three days later and spent the next month in hospital, eventually being diagnosed with manic depression. My hospitalisation was, I believed at the time, part of a role-play to trick the authorities and hospital staff. The mission I thought I was on was so top secret I wasn’t allowed to know what it was.
“For a while I thought the side effects of my medication were a deliberate attempt to disable me, because people were afraid that I was a threat and might see through my mission. It was as if I was doing something important that others didn’t want me to do and I needed to be controlled.
“Reality started to come back slowly. The police were interviewing me to find out what had happened. I thought I was doing some part-time espionage before getting back to my regular life, but when I heard I’d lost my job something clicked and I realised my psychotic thoughts hadn't been real at all.
“About a year later I stopped taking my medication and had another episode of mania. I am still on medication and did self-management training with the Manic Depression Fellowship. It's odd having a chronic mental health diagnosis. I have been well for much longer than I was ever ill, but the diagnosis is with me every day."
Delusions and voices have been a daily feature of Richard’s life for more than 10 years. Despite this he recently completed a master's degree in broadcast journalism and successfully runs his own business.
"When I was 21 I had a bad experience with hallucinogenic mushrooms, after which I started having delusions and hallucinations. Voices in my head said unkind things and I had suspicious thoughts that felt like they came from outside me. I was diagnosed with paranoid schizophrenia and the thoughts and voices have been with me ever since.
"A lot of the time the thoughts and voices are like another layer of interaction with people and the world. It's as if there are two coexisting realities. If I am listening to the radio, for instance, the rational part of me knows that the programme is being transmitted to lots of listeners and that it is a one-way form of communication. My delusional thinking, however, makes me think that the radio can project what I say out loud to the people making the show and all the listeners.
"My delusions will also make me think that a lot of the discussion in the programme has a special meaning or relevance to me. For example, the host of a show might mention that they are going to the dentist soon. If I happen to have a dental appointment in the near future, then it can seem like the presenter has just dropped that into the conversation as a hidden message. They aren’t going to the dentist, but they want me to understand that they know I will be.
"In truth, when something like that happens it is, of course, just a coincidence, but there's a part of my thinking for which it becomes another reality.
"I've come to accept that they are an ongoing part of my life, but there are times when it is hard to deal with. Out shopping, it sometimes seems people are looking at me in a sinister way because they don’t like something about me. The truth is they're probably noticing my clothes or are just looking in my direction.
"Nonetheless it can get me down, to the point where I won’t go out of the house. In the past it has made me feel depressed, even suicidal. At times like that it helps to have friends who can either tell me to stop thinking rubbish or, if needs be, help me work through my delusions and do some reality-checking.
"I had some cognitive behavioural therapy when I first got these symptoms. It was helpful because it gave me another way to work through negative emotions and keep on top of things that could be disabling. I also take medication and have decided that I always will.
"The media consultancy company I've just set up keeps me busy. That’s important too, because when I have lots of work on it helps me keep focused, rather than drift off with my delusions."
Andrew is in his 50s and lives on the South Coast. His early psychotic experiences lasted a number of years and had a profound effect on his life. He got better, however, and has been free of symptoms for more than 15 years. He recently completed an MA in Social Policy.
The first time things didn’t feel right was when I was in my early 20s at university. I'd got some compensation money following an accident in my teens when I lost a leg. My friends were trying to persuade me to buy a house. The idea of going to see an estate agent was intensely frightening. They seemed like oppressive "non-beings" who could expose me as inadequate in some way.
This uncomfortable feeling got stronger. I stopped going to lectures because I thought it would be too much, and failed my degree as a result.
I then fell out with my parents because of my mental state. Simple misunderstandings preoccupied me and seemed sinister. I was mistrustful and thought they were deliberately not looking after me and trying to make things difficult.
I ended up living in my car. As I drove around it seemed that other drivers were singling me out for observation. Certain features of the landscape, like radio masts, would also make me feel suspicious. I neglected myself. I felt disadvantaged by my circumstances and by the fact I couldn’t have the happiness that a good job and a relationship would bring. I thought this could make everything right but nobody understood.
I went into hospital a number of times, was given injections, improved a bit and was then discharged to a hostel. I would get a low-paid job and after a while stop taking my medication. My false or erroneous beliefs became more powerful and at the time they seemed very real.
I used to imagine that the place where I worked and the people in it were not what they seemed, that it was all hiding something else going on beneath the surface. My colleagues seemed to drop significant words or phrases into conversations and give each other signals that excluded me. I would interpret personal or distinctive features as clues to hidden identities, part of another secret world.
When these false beliefs became stronger it became too difficult to stay in a job. I became a vagrant. The delusions preoccupied me and I travelled around the country trying to uncover signals or evidence of enemy plans to assassinate the Archbishop of Canterbury and bring down the state.
I believed that people in public sector jobs could live for 500 years and had spent a period of their life as a monarch. The phrase "Jesus Lives" also took on a literal sense.
In 1991 I ended up back in hospital. I was given tablets I'd never tried before. They made me feel better and after a few months I was discharged. Since then I've never needed to go back. I take my pills every day. I see a counsellor once a week and don’t have any more strange ideas. I enjoy my independence and the choices I can make for myself.
Self-harming behaviour is a relatively common complication in people with psychosis. One study found that 1 in 10 people with psychosis also had a history of self-harm.
The risk of self-harm is thought to be highest in people experiencing their first episode of psychosis that is currently going untreated.
If you are self-harming, you should see your doctor for help.
If you suspect that a friend or relative is self-harming, look out for any of the following signs:
- unexplained cuts, bruises or cigarette burns, usually on their wrists, arms, thighs and chest
- keeping themselves fully covered at all times, even in hot weather
Read more about spotting the signs of self-harm in others.
The person who is self-harming may feel deep shame and guilt, or may feel confused and worried by their own behaviour. It’s important to approach them with care and understanding.
They may not wish to discuss their self-harm with you, but you could suggest that they speak to an anonymous helpline or see their doctor.
Another serious complication of psychosis is that people with the condition have an increased risk of suicide.
It is estimated that 1 in 5 people with psychosis will attempt suicide at some point in their life and 1 in 25 people with psychosis will kill themselves.
For more information and advice, see Suicide - getting help.
If you are worried that someone you know may be considering suicide, recommend that they contact one or more of the organisations above and encourage them, in a non-judgemental way, to talk about how they are feeling.
If the person has previously been diagnosed with a mental health condition, such as depression, you can speak to a member of their care team for help and advice.
Read more about the suicide warning signs and what to do if you think someone is thinking about suicide.
Complications of antipsychotics
Using antipsychotics on a medium to long term basis can cause a number of complications. Some of the more common ones are discussed below.
Weight gain can be a common complication of many commonly used antipsychotics.
It is thought there are two main reasons weight gain can occur:
- antipsychotics can lead to an increase in appetite
- antipsychotics can slow down your metabolism meaning that you burn off fat at a reduced rate
To combat the reduction in your metabolism you will probably be recommended to take more exercise as this can help burn off the excess fat.
Metabolic syndrome is a term used to describe a number of related conditions that are linked with weight gain, such as:
Because of the risk of metabolic syndrome it is usually recommended that you receive regular blood tests and blood pressure tests while taking an antipsychotic.
If tests show that you do have an increased risk of developing a condition such as heart disease then there are a number of preventative treatments available such as statins which can help lower cholesterol levels.
Another common complication of long-term antipsychotic use is tardive dyskinesia (TD).
TD is a movement disorder when a person experiences involuntary movements such as twitching, tics, grimaces, tremors and spasms.
TD usually starts in the face and mouth before spreading to the rest of the body.
The mental health charity Mind estimated that 1 in 5 people who have been taking an antipsychotic for four years or more will develop TD.
In some cases stopping taking an antipsychotic will lead to relief of symptoms of TD (though this may not always be safe to do and has to be balanced against the risk of a relapse) though it can take several years for this to occur.
In some cases TD can be a permanent condition.
There are a number of treatments that can sometimes lead to an improvement in symptoms of TD, such as:
- clonazepam – a medication used in the treatment of epilepsy
- vitamin E supplements – check with the doctor in charge of your care before taking vitamin supplements as they are not safe or suitable for everyone
