Schizotypal Personality Disorder

Schizotypal personality disorder is a mental disorder characterized by thought disorder, paranoia, a characteristic form of social anxiety, derealization, transient psychosis, and unconventional beliefs. People with the condition struggle to form social connections, often believing others hold negative views of them, and frequently interpret situations as strange or carrying unusual significance. It affects an estimated 3 percent of the general population, with estimates ranging from 1.37 to 5.2 percent depending on the study population, typically has its onset between ages 10 and 20, and is classified in the DSM-5 as a Cluster A personality disorder, though ICD-11 instead lists it among psychotic disorders.
