Paranoid personality disorder (PPD): Paranoid personality disorder is a non-psychotic mental health condition that involves extreme, long-term mistrust and suspicion of other people.They may be bizarre (highly unlikely to happen) or non-bizarre (technically possible), but they are always detached from reality. These false beliefs usually involve paranoia about conspiracies and other perceived threats. Delusional disorder: People with delusional disorder have delusions that persist across time, but they don’t experience other symptoms of psychosis (such as hallucinations).Paranoid delusions, especially involving fears about persecution, are common in people with schizophrenia. Schizophrenia: Schizophrenia is a psychotic disorder that causes disturbances and disorganization in speech, emotions, thinking, movement, perceptions of reality, and social interaction.
This may include paranoid delusions, hallucinations (hearing or seeing things that others can’t), or both.
Some people with bipolar disorder experience symptoms of psychosis (breaking from reality).
