Disorders / July 14, 2019

Psychosis is a serious mental disorder characterized by thinking and emotions that are so impaired, that they indicate that the person experiencing them has lost contact with reality.

People who are psychotic have false thoughts (delusions) and/or see or hear things that are not there (hallucinations). These are referred to as “positive” symptoms; “negative” symptoms like loss of motivation and social withdrawal can also occur.

These experiences can be frightening and may cause people who are suffering from psychosis to hurt themselves or others. It is important to see a doctor right away if you or someone you know is experiencing symptoms of psychosis.

Psychosis affects three out of every 100 people. It is most likely to be diagnosed in young adults, but psychosis can happen to anyone.

What is Psychosis?

Recognizing The Signs of Psychosis

Early stage psychosis:

  • Difficulty concentrating
  • Depressed mood
  • Sleep changes—sleeping too much or not enough
  • Anxiety
  • Suspiciousness
  • Withdrawal from family and friends
  • Ongoing unusual thoughts and beliefs

Later stage psychosis:

  • Delusions
  • Hallucinations
  • Disorganized speech—switching topics erratically
  • Depression
  • Suicidal thoughts or actions
  • Difficulty functioning

A delusion is a false belief or impression that is firmly held even though it is contradicted by reality and what is commonly held as true. There are delusions of paranoia, grandiose delusions, and somatic delusions.

People who are experiencing a delusion of paranoia might think that they are being followed when they are not or that secret messages are being sent only to them through media. Someone with a grandiose delusion will have an exaggerated sense of his or her importance. Somatic delusions are the belief that you have a terminal illness when you are healthy.


A hallucination is a sensory perception in the absence of outside stimulus. That means seeing, hearing, feeling, or smelling something that isn’t present. A person who is hallucinating might see things that don’t exist or hear people talking when he or she is alone.

Delusions and hallucinations seem real to the person who is experiencing them.

Causes of Psychosis

Each case of psychosis is different, and the exact cause is not always entirely clear. There are, however, certain illnesses that cause psychosis. There are also triggers like drug use, lack of sleep, and other environmental factors. In addition, certain situations can lead to specific types of psychosis to develop (see “Types of Psychosis” below).


Illnesses that can cause psychosis:

  • Brain diseases such as Parkinson’s disease, Huntington’s disease, and some chromosomal disorders
  • Brain tumors or cysts
  • Dementia (including Alzheimer’s disease)
  • HIV, syphilis, and other infections that attack the brain
  • Some types of epilepsy
  • Stroke
Environmental Causes

Psychosis can be triggered by the use of alcohol and illegal drugs, including stimulants such as methamphetamine (meth) and cocaine. Hallucinogenic drugs like LSD (acid) often cause users to see things that are not really there, but this effect is temporary. People who do not get enough sleep for long periods of time can experience symptoms of psychosis. Some prescription drugs like steroids and stimulants can cause symptoms of psychosis.

Risk Factors For Developing Psychosis

It is not currently possible to precisely identify individuals who are likely to develop a psychotic disorder. However, research has shown that genetics may play a role.

If one identical twin develops psychosis, there is a 50 percent chance the other twin will as well. Individuals with a close family member (parent or sibling) who has a psychotic disorder are more likely to develop a psychotic disorder.

Children born with the genetic mutation known as 22q11 deletion syndrome are at risk for developing a psychotic disorder, especially schizophrenia.

Types of Psychosis

Some kinds of psychosis are brought on by specific conditions or circumstances.

Brief Reactive Psychosis

Extreme personal stress like the death of a family member can bring on symptoms of psychosis. Someone experiencing brief reactive psychosis will recover in a few days.

Drug or Alcohol Related Psychosis

Use of alcohol and drugs can sometimes cause symptoms of psychosis. These symptoms might go away immediately when the effect of the alcohol or drug wears off, but this is not always the case. People who are addicted to alcohol and certain drugs can experience psychotic symptoms if they suddenly stop drinking or taking the drug to which they are addicted.

Organic Psychosis

A head injury or an illness that affects the brain like Parkinson’s disease can cause symptoms of psychosis.

Psychotic Disorders

The following types of psychoses are called psychotic disorders. They can be triggered by stress, drug or alcohol use, injury or illness, or they can appear on their own.

Bipolar Disorder

When someone has bipolar disorder, his or her moods swing from very high to very low. When his or her mood is high and positive, he or she may have symptoms of psychosis. The individual may feel extremely good and believe he or she has special powers. When his or her mood is depressed, the individual may have psychotic symptoms that make him or her feel angry, sad, or frightened. These symptoms include thinking someone is trying to harm him or her.

Delusional Disorder

A person suffering from delusional disorder strongly believes in things that are not real.

Psychotic Depression

This is major depression with psychotic symptoms.


Schizophrenia is psychosis that lasts longer than six months. Schizophrenia is a lifelong disease.

How is Psychosis Diagnosed

Psychosis is diagnosed through a psychiatric evaluation. That means a doctor will watch the person’s behavior and ask questions about what he or she is experiencing. Medical tests and X-rays may be used to determine whether there is an underlying illness causing the symptoms.

Diagnosing Psychosis in Children & Teenagers

Many of the symptoms of psychosis are perfectly normal in young people. For example, a teenager may suddenly need more sleep in response to changes in their body. Small children often have imaginary friends with whom they talk. If you are worried about psychosis in a child or adolescent, describe the individual’s behavior to a doctor.

Treatment of Psychosis

Treating psychosis may involve a combination of medications and therapy. Most people recover from psychosis with treatment.

Rapid Tranquilization

Sometimes people suffering from psychosis can become agitated and be at risk of hurting themselves or others. In those cases, it may be necessary to calm them down quickly. This method is called rapid tranquilization. A doctor or emergency response personnel will administer a fast-acting shot or liquid medicine to relax the patient right away.
