What is Paranoid Personality Disorder?
People who have paranoid personality disorder (PPD) distrust other
people and suspect that everyone is out to get them. They
constantly fear being exploited or betrayed.
How does it occur?
Paranoid personality disorder usually starts in childhood or in the
teen years. The exact cause of PPD is not known. Experts think it
may be caused by differences in the brain or nervous system. It
might also be related to things such as child abuse or a family
history of mental illness. The risk is increased if someone in the
family has schizophrenia.
What are the symptoms?
The symptoms of PPD are:
- thinking that others are trying to cheat, hurt, or fool them
- worrying that friends or family are not loyal
- not discussing things for fear the information will be used
against them
- becoming easily insulted or insulting others
- holding grudges
- always thinking that other people are attacking them
- worrying that their significant other is cheating on them
- having a poor self-image
- not having a sense of humor.
Because people with this disorder avoid closeness with others, they
may appear calculating and cold. Usually more men are diagnosed
with PPD than women.
How is it diagnosed?
Your health care provider will ask about your symptoms,
relationships, medical history, and substance abuse history.
Paranoia is a possible risk of drug use and abuse (for example,
alcohol, marijuana, amphetamines, cocaine, and PCP). He or she may
also:
- give you a personality test
- suggest lab tests to rule out medical problems
- make sure medicines are not causing or increasing your symptoms
- rule out other mental health problems.
How is it treated?
Medicines and therapy are effective ways to treat the disorder.
However, you may not seek treatment because you may be suspicious
of the health care provider. Without treatment the symptoms will
continue.
Medicines may help treat severe anxiety or delusions.
Psychotherapy can help you see yourself more clearly. It helps you
recognize the effects of your behavior on others. This can help
you change behaviors that get in the way of living a satisfying
life. Cognitive-behavior therapy (CBT) is a way to help you
identify and change thoughts you have that are not realistic.
When should I seek help?
If your symptoms are seriously interfering with your daily life,
seek help from your health care provider or a mental health
professional. For more information, contact the National Alliance
for the Mentally Ill (NAMI) or the National Mental Health
Association (NMHA).
