There appears to be a link between anxiety and psychosis, particularly when anxiety is persistent or severe.
Anxiety symptoms have some overlaps with psychotic features, such as difficulty concentrating or making decisions, sleep difficulties, and a sense of impending danger or panic.
While anxiety may cause changes in behaviors, psychosis is not always one of them. Psychosis causes a break in reality, and although this can occur with anxiety, it does not tend to cause any noticeable changes.
Anxiety and psychosis may both result from past trauma and physical or other mental health conditions. Psychosis may also develop from other general medical conditions.
To treat anxiety and psychosis, doctors may use a combination of medication and therapy. Support is available for both through talk therapies and community and organization-led programs.
