Contrary to what some might expect, psychosis happens in stages (early, acute, and recovery) and can thus potentially be detected early enough to intervene before the episode worsens.
In early stages of psychosis, the person may experience changes in behaviors and thoughts and begin to withdraw from friends and family. Other early signs can include:
Hearing, seeing, tasting or believing things that others don’t (e.g., hearing ringing or voices; seeing shadows or flashes of light)
Persistent, unusual thoughts or beliefs that can’t be set aside regardless of what others believe
Strong and inappropriate emotions or no emotions at all
Difficulty sleeping
A sudden decline in self-care
Worsening performance in school or at work
Trouble thinking clearly or concentrating
As the psychosis develops, hallucinations and delusions may come into play. Psychotic episodes taper off with treatment.
