Definition:
Paranoia is an exaggerated distrust of others that is not based on fact.

As a psychotic feature of bipolar disorder, schizoaffective disorder or schizophrenia, paranoia may manifest as delusions of persecution.

Paranoid personality disorder is classed as a separate mental illness in its own right, where an unfounded belief that the patient is being persecuted is the primary symptom.
