MD is supposed to be a common clinical phenomenon. According to some authors,<unk>  is as frequent as overt<unk> . Although<unk>  can be found at any age, it has been observed more commonly after mid-life. Making the diagnosis and the management of MD in clinical practice are complicated by the fact that he who has got MD is unaware of his mental illness. Patients with MD are reluctant to associate their physical symptoms with an affective disorder and refuse mental health care. As a rule, these patients attribute their disturbances to physical illness, seek medical care for them, and report only somatic complaints to their physicians, with the consequence that many of such<unk> s are not recognized or are misdiagnosed and mistreated Estimates of depressed patients who are correctly identified and treated range from 5% to 60%. Recent data show that about 10% of people who consult a physician for any reason originally suffer from affective disorders disguised by physical symptoms.
