Paranoid Personality Disorder: Causes and Symptoms

As defined in one of my previous articles about personality disorder. I hinted at the hell of being a sufferer of personality disorders. You can check on the signs of Narcissistic Personality Disorder for some clues.

Paranoid Personality Disorder (PPD) ( Paranoid behavior ) is yet another popular one in the list of personality disorders. Sufferers of Paranoia are characterized by excessive distrust and suspiciousness.

Even when there is no reason to be suspicious, one with paranoid behavior always suspect and perceive others as threat. Paranoid personality disorder (PPD) being among the group of conditions called eccentric personality disorders, can only be diagnosed if it begins no later than early adulthood.

Just like any other personality disorders, Paranoid Personality Disorder manifests as a response to some personal and social situations. Sufferers of Paranoid Personality Disorder take their degree of paranoia to another level by falsely believing that people are against them and that they are being victimized.

Sufferers of PPD are always hypersensitive to any criticism of themselves as they bear grudges for a long time. More of the symptoms come after a short explanation on the causes.

On this note, it is observed that early childhood experiences like solitariness, poor peer relationships, social anxiety, underachievement in school and hypersensitivity can also play a role in the development of PPD.


Another research about the genetic factors also suggests that there is a risk for this disorder to be “passed down” from a sufferer to their children.
