Coping With Schizophrenia

Schizotypal Personality Disorder Symptoms

Paranoia

People experiencing paranoia believe that others are persecuting them and have delusional ideas about themselves as central figures in scenarios that in reality have little relevance to them. Minor feelings of paranoia are common, but severe paranoia can cause significant fear and anxiety and can have a pronounced effect on social functioning. Feelings of paranoia can be observed with many psychological disorders, including schizophrenia, as well as with a number of medical diseases, ranging from Alzheimer's disease to multiple sclerosis, that can affect brain function.

What is schizotypal personality disorder?

Schizotypal personality disorder is a mental disorder that belongs to the group of mental illnesses called personality disorders. Therefore, like other personality disorders, it is characterized by a consistent pattern of thinking, feeling, and interacting with others and with the world that tends to cause significant problems for the sufferer. Specifically, schizotypal personality disorder tends to be associated with a pattern of odd, eccentric feelings, perceptions, behaviors, and relating to other people that interferes with the individual's ability to function. Individuals with this illness have a tendency to be loners. They may also be paranoid, although their level of suspiciousness might not rise to the level of being completely out of touch with reality (delusional). As with other personality disorders, the person with schizotypal personality disorder is usually an adolescent or adult before they can be assessed as meeting the full symptom criteria for the diagnosis of this illness.

Schizotypal personality disorder tends to occur in about 3% of adults, more often in males than in females. It is thought to be part of a continuum of illnesses related to schizophrenia, so it is dually grouped with other personality disorders and with schizophrenia and other psychotic disorders.
