• Symptoms are not related to another cause, such as medications or drug or alcohol abuse. For example, some medications can cause aggression or suicidal thoughts in some people, but they do not necessarily have personality disorders. The Diagnostic and Statistical Manual of Mental Disorders is used by clinicians and psychiatrists to diagnose psychiatric illnesses. The American Psychiatric Association publishes the DSM and released its fifth edition in 2013. The DSM-5 covers all categories of mental health disorders for both adults and children and is widely used in the United States for psychiatric diagnosis, treatment recommendations, and insurance coverage purposes. The DSM-5 lists 10 personality disorders (PD) and allocates each to one of three groups or “clusters”: A, B, or C. The following are the classifications for the three major clusters:

DIFFICULT DISORDER

A personality disorder is a variation of a mental disorder. People who suffer from personality disorders generally are very unyielding and have an unhealthy pattern of behavior and personality that affects how they think, function, and behave. They tend to have trouble in certain social situations and difficulty picking up on the actions and words of people. That causes significant problems and limitations in relationships, social activities, work, and school.
