A personality disorder is a way of thinking, feeling and behaving that deviates from cultural and societal expectations, causes distress or problems functioning and lasts for a duration of time.1 While every individual experiences symptoms a little differently, people with personality disorders typically share both an inability to regulate their emotions and a tendency to alienate others. Many individuals can be unpleasant to interact with and are generally dissatisfied with their current circumstances (with some notable exceptions). According to a 2007 study, 9.1% of people in the U.S. met the diagnostic criteria for any type of personality disorder.1
Ten specific personality disorders are grouped into three categories called clusters. Those in the same cluster have similarities, but each has its own defining characteristics.2
Cluster A: Odd or Eccentric Behavior
Paranoid personality disorder: A pattern of pervasive distrust and suspiciousness in which other peoples’ motives are seen as mean or spiteful.2 According to a 2007 study, 2.3% of people in the U.S. met the diagnostic criteria for paranoid personality disorder.1 Symptoms include:
- Suspects (without sufficient evidence) others are exploiting, harming or deceiving them
- Is preoccupied with unjustified doubts about the loyalty or trustworthiness of friends or associates
- Reluctance to confide in others because of unwarranted fear information will be used maliciously against them
- Interprets harmless remarks or events as threatening or insulting
- Persistently bears grudges (e.g. is unforgiving of insults, injuries or slights)
- Perceives attacks on character or reputation not apparent to others; reacts in anger or with a counterattack
- Has recurring suspicions (without justification) regarding fidelity of spouse or sexual partner3
Schizoid personality disorder: A pattern of detachment from social relationships and a limited range of emotional expression.2 According to a 2007 study, 4.9% of people in the U.S. met the diagnostic criteria for schizoid personality disorder.1 Symptoms include:
- Takes pleasure in few, if any activities

- Ideas of reference (e.g. imagining strangers are noticing or somehow communicating with them)

- Inappropriate or constricted ways of expressing emotion (affect)
- Odd, eccentric or strange behavior or appearance

- Excessive social anxiety that does not decrease with familiarity and tends to be associated with paranoid fears, rather than negative thoughts about oneself5
Cluster B: Dramatic, Emotional or Erratic Behavior

If you know someone who has characteristics of more than one personality disorder, the diagnosis “personality disorder not otherwise defined” is a possibility. Mental health professionals use this label for people who do not quite fit the formal definition of one of the established disorders, but clearly have problems with emotions and relationships. If any of the troubling symptoms mentioned above are interfering with your functioning or that of a loved one, there is hope. Most personality disorders can be effectively treated using different types of psychotherapy, and in some instances, medication.
