Is paranoid personality disorder related to schizophrenia?

Douglas E. Severance, MD
Family Medicine
Paranoid personality disorder shares some qualities with schizophrenia, but it is a different type of mental illness. People with paranoid personality disorder may be more likely to have a parent, sibling, or relative with schizophrenia. This means that there may be a genetic link between schizophrenia and paranoid personality disorder.

Symptoms of paranoid personality disorder that are similar to schizophrenia include withdrawing from others and being concerned that others are plotting to cause harm. Unlike schizophrenia, people with paranoid personality disorder do not usually have hallucinations. Since people with the disorder may distrust the medical system, they may not seek help for their illness. However, medications and psychotherapy have been shown to help people recover from the disorder.
