Rare mental and behavioral diseases

Abnormality is also called as dysfunctional behaviour which refers to the behavioural characteristic assigned to those with conditions regarded as rare or dysfunctional. Behaviour is considered to be abnormal when it is atypical or out of the normal or usual, it consists of unpleasant behaviour, and results in deterioration in the individual's functioning. Abnormality is one, which is considered as different from specific ethical social and cultural expectations. These expectations are broadly dependent on age, gender, traditional and societal categorizations. The definition of abnormal behaviour is an often debated issue in abnormal psychology because of these subjective variables.
