Psychosis is characterized by an impaired relationship with reality. And it is a symptom of serious mental disorders. People who are psychotic may have either hallucinations or delusions.
Hallucinations are sensory experiences that occur within the absence of an actual stimulus. For example, a person having an auditory hallucination may hear their mother yelling at them when their mother isn’t around. Or someone having a visual hallucination may see something, like a person in front of them, who isn’t actually there.
The person experiencing psychosis may also have thoughts that are contrary to actual evidence. These thoughts are known as delusions. Some people with psychosis may also experience loss of motivation and social withdrawal.
These experiences can be frightening. They may also cause people who are experiencing 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.
Symptoms of psychosis include:
Delusions and hallucinations are two very different symptoms that are both often experienced by people with psychosis. Delusions and hallucinations seem real to the person who is experiencing them.
A delusion is a false belief or impression that is firmly held even though it is contradicted by reality and what is commonly considered 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 to them. Someone with a grandiose delusion will have an exaggerated sense of importance. Somatic delusion is when a person believes they have a terminal illness when in reality they are healthy.
A hallucination is a sensory perception in the absence of outside stimuli. 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 they are alone.
Each case of psychosis is different, and the exact cause is not always 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.
Illnesses that can cause psychosis include:
Also some types of dementia may cause psychosis, such as:
It’s not currently possible to precisely identify who is likely to develop psychosis. However, research has shown that genetics may play a role.
People are more likely to develop a psychotic disorder if they have a close family member, such as a parent or sibling who has a psychotic disorder.
Children born with the genetic mutation known as 22q11.2 deletion syndrome are at risk for developing a psychotic disorder, especially schizophrenia.
Some kinds of psychosis are brought on by specific conditions or circumstances that include the following:
Brief psychotic disorder, sometimes called brief reactive psychosis, can occur during periods of extreme personal stress like the death of a family member. Someone experiencing brief reactive psychosis will generally recover in a few days to a few weeks, depending on the source of the stress.
Psychosis can be triggered by the use of alcohol and illegal drugs, including stimulants such as methamphetamine and cocaine. Hallucinogenic drugs like LSD often cause users to see things that are not really there, but this effect is temporary. Some prescription drugs like steroids and stimulants can also cause symptoms of psychosis
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.
A head injury or an illness or infection that affects the brain can cause symptoms of psychosis.
Psychotic disorders can be triggered by stress, drug or alcohol use, injury, or illness. They can also appear on their own. The following types of disorders may have psychotic symptoms:
When someone has bipolar disorder, their moods swing from very high to very low. When their mood is high and positive, they may have symptoms of psychosis. They may feel extremely good and believe they have special powers.
When their mood is depressed, the individual may have psychotic symptoms that make them feel angry, sad, or frightened. These symptoms include thinking someone is trying to harm them.
A person experiencing delusional disorder strongly believes in things that are not real.
This is major depression with psychotic symptoms.
Schizophrenia is a lifelong disease that is generally accompanied by psychotic symptoms.
Psychosis is diagnosed through a psychiatric evaluation. That means a doctor will watch the person’s behavior and ask questions about what they are experiencing. Medical tests and X-rays may be used to determine whether there is an underlying illness causing the symptoms.
Many of the symptoms of psychosis in adults are not symptoms of psychosis in young people. For example, small children often have imaginary friends with whom they talk. This just represents imaginative play, which is completely normal for children.
But if you are worried about psychosis in a child or adolescent, describe their behavior to a doctor.
Treating psychosis may involve a combination of medications and therapy. Most people will experience an improvement in their symptoms with treatment.
Sometimes people experiencing psychosis can become agitated and be at risk of hurting themselves or others. In these 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 quickly relax the patient.
Symptoms of psychosis can be controlled with medications called antipsychotics. These medicines reduce hallucinations and delusions and help people think more clearly. The type of medicine that is prescribed will depend on the symptoms.
In many cases, people only need to take antipsychotics for a short time to get their symptoms under control. People with schizophrenia may have to stay on medications for life.
Cognitive behavioral therapy means meeting regularly to talk with a mental health counselor with the goal of changing thinking and behaviors. This approach has been shown to be effective in helping people make permanent changes and more effectively manage their illness. It is often most helpful for psychotic symptoms that don’t completely resolve with medications.
Psychosis does not have many medical complications. However, if left untreated, it can be challenging for people experiencing psychosis to take good care of themselves. That could cause other illnesses to go untreated.
Most people who experience psychosis will recover with proper treatment. Even in severe cases, medication and therapy can help.
