Document Summary
Psychological or mental, disorders: symptoms reflecting abnormalities of the mind. Medical model: the conceptualization of psychological disorders as diseases that, like physical diseases, have biological causes, defined symptoms, and possible cures. Diagnosis: clinicians seek to determine the nature of the patient"s mental disease by assessing symptoms. Symptoms: behaviours, thoughts, and emotions suggestive of an underlying abnormal syndrome. Syndrome: a coherent cluster of symptoms usually due to a single cause. Each disorder is named and classified as though it were a distinct illness. Comorbidity: the co-occurrence of two or more disorders in a single individual. Specifiable pattern of causes (or etiology) may exist for different psychological disorders. Diathesis-stress model: a person may be predisposed for a psychological disorder that remains unexpressed until triggered by stress. Intervention-causation fallacy: search for biological causes of psychological disorders in the brain and body tends to invite particular error in explanation.
