Psychosis Signs, Symptoms & Effects

Psychosis, a debilitating mental and emotional state, is a key feature of a group of mental health conditions known collectively as psychotic disorders.

Understanding Psychosis

Learn about psychosis

Symptoms of these conditions are severe and alter a person’s ability to think clearly, make good judgments, respond emotionally, communicate effectively, understand reality, and behave appropriately.

Individuals experiencing psychosis have challenges staying in touch with reality and are usually unable to meet the demands of activities of daily living. A psychotic state, or psychosis, is a set of experiences that can be described as the loss of contact with reality, but not in a way that is a part of a person’s religious or cultural beliefs and traditions.

Psychosis, while not a specific illness, is a very important indicator of the presence of a psychotic disorder that will require professional intervention and residential treatment. This experience can take many forms, and the severity of the symptoms will vary for each affected individual.

Statistics

Psychosis statistics

The percentage of people who experience psychosis at any one time varies tremendously across countries and cultures, ranging from 0.66% in Vietnam to 45.84% in Nepal. But in sum, about 1% of the world’s population suffers from psychotic disorders, reportedly affecting men and women equally. Generally, people who have psychotic disorders experience their first episode between the ages of 18 and 24. While it is quite rare, some adolescents can display early symptoms of psychosis, which usually indicates that a psychotic disorder will develop later in life.

Causes and Risk Factors

Causes and risk factors for psychosis

With the exception of medical or substance-induced psychosis, the specific cause for a psychotic disorder remains unknown. Most researchers agree that a combination of genetics, physiological characteristics, and environmental causes likely work together to cause the onset of a psychotic disorder. Some of the most common causes for psychotic disorders and accompanying psychosis may include:

Genetic: While a specific gene has yet to be isolated, it is well-accepted that most psychotic disorders have a hereditary component. People who have a parent or sibling with a psychotic disorder or related mental illness are at increased risk for developing psychotic disorders. Additionally, imaging studies performed on the brains of those who have psychotic disorders indicate that there are subtle differences in the structure and function of the brain of those who are suffering from this type of mental illness.

Environmental: Psychotic episodes are often brought about by a life stressor so great that it causes a person to enter psychosis. This response may be as the result of triggering a chronic but dormant problem like physical or sexual abuse.

Risk Factors:

  • Tobacco, marijuana, alcohol and other substance abuse
  • Prenatal exposure to infectious agents
  • Exposure to environmental toxins
  • Having certain mental health conditions such as bipolar disorder, schizophrenia, or depression
  • Social isolation
  • Poverty
  • Lack of support system
