What is an anti-social disorder?it's a personality disorder .
There are many types of anti-social behavior disorder, and many of them have a root cause in other psychological or psychiatric conditions. For example, to take a mild non-aggressive one, disocciative behavior can be anti-social without being disruptive or aggressive. In this particular disorder, the patient will become isolate, shunning company except perhaps one trusted person, perhaps become agoraphobic and may have associated symptoms such as anorexia nervosa or bulimia or obsessive compulsive disorder. A person like this may have suffered rejection or cruelty in childhood and have learned that it is safer to be alone. They may choose to avoid eye contact and gatherings where there are many people. Other forms of anti-social behavior are more violent.
Anti social disorders are typified by an individual's inability to follow social norms and mores in their interactions. Most of the time, they are seen as actions against the social structure and contrary to the interests of others. The critical element in anti- social behavior seems to be the repeated actions or consistent pattern of behavior against others or a social expectation. At times, the actions are done for individual interest, while at others, the motivation is simply to go against the norm. It is seen as a disorder because of the presence of these behaviors at childhood and progressing into adulthood.
