Effect of Physical Activity without Use of Antipsychotics Compared to Physical Activity and Antipsychotics for Patients with Active Psychosis: A Systematic Review [Internet].

Psychosis is a set of symptoms, rather than a specific disease. A person with psychosis experiences hallucinations and cognitive disturbances. The condition can be transient and benign, but is for some people serious and prolonged, sometimes chronic. Severe psychosis disorders develop in phases and often have precursors with "common" symptoms such as depression, anxiety and social isolation. The most common psychosis disorder is schizophrenia. It is estimated that one percent of the world's population is affected by schizophrenia. In Norway it is estimated that between 600 and 800 people are affected every year.
