The biological model of abnormality

This model suggests that the causes of mental disorders resemble those of physical illnesses.

 Clusters of symptoms can be identified and a diagnosis made, followed by suitable treatment.

 There is some evidence that the following may account for mental disorders:
   -genetics,

-       -biochemistry,

         -neuroanatomy,

         - infections.

 While this approach has received some scientific support and has contributed to treatment it has been criticized in that:
-It focuses on symptoms rather than the person’s thoughts and feeling.

      -It is less appropriate for disorders wit psychological symptoms such as eating disorders.

      -There is some debate as to whether mental disorders are the same as physical illnesses.

      -The treatments based on the medical model (e.g. drugs, ECT, and psychosurgery) may have unpleasant side effects and their efficacy has been challenged.
