Facts About Psychosis

single image

Psychosis is defined as a fundamental derangement of the mind (much like schizophrenia) characterized by loss of contact with reality, with evidence of this being delusions (false beliefs), disorganized speech/behavior, and auditory and/or visual hallucinations.

The word “psychosis” was first used by Ernst Von Feuchtersleben in 1845 as an alternative to insanity. The word was used to distinguish disorders of the mind, as opposed to “neurosis” which at the time was thought to stem from a problem with the nervous system.

The differences between major psychoses was made by Emil Kraepelin, who tried to create a synthesis of various disorders of the mind identified by 19th century psychiatrists, who grouped diseases together based on the classification of symptoms.
During the 1970’s recovery was first coming to light in the mainstream of the mental health field. This movement was primarily driven by people who have experienced psychosis. This has led to a greater awareness that mental illness is not always a lifelong disability. It is essential to have effective support.

Prognosis, Treatment and Complications of Psychosis

How well a person recovers is dependent on the cause or causes of the psychosis. If the cause can be corrected, the prognosis is often good. Treatment usually consists of antipsychotic medication, and chronic conditions such as schizophrenia could require long-term treatment with antipsychotics. Often care in a hospital is required for the safety of the patient. If the condition is left untreated it could lead to complications, such as the patient harming himself or others.

Prevention is entirely dependent on the cause. An example would be avoiding alcohol abuse, if you have experienced alcohol induced psychosis.

Call your health care provider immediately or a mental health professional if you or a member of your family is experiencing a psychotic episode. If necessary, take the afflicted to the nearest emergency room. Psychosis can place the afflicted person and surrounding people in danger, so be cautious when approaching someone who is demonstrating symptoms of psychosis.
