64 Indeed, certain somatic symptoms such as sleep disturbances, diffuse bodily pains and aches, fatigue, changes of appetite, etc, may characterize

both the pathophysiological process of a discrete medical condition and a depressive disorder as well. The differential diagnosis may be difficult. The role and significance of somatic symptoms for the diagnosis Inhibitors,research,lifescience,medical of depression in selleck chem Imatinib medically ill patients have been a controversial issue in the scientific literature. Meanwhile, a clinically reasonable consensus has been arrived at that the DSM-IV criteria for major depression do not require significant modification for patients with medical comorbidities.65-67 Somatic symptoms can positively contribute to a diagnosis if they are assessed in line with typical concomitant affective, behavioral, and cognitive symptoms of depression.9 For a primary care physician It Is Inhibitors,research,lifescience,medical Important to know that at least 20% to 30% of patients with chronic medical conditions suffer from a coexisting depression.68 It must be assumed that, even In Inhibitors,research,lifescience,medical those patients being diagnosed with an acute somatic disease for the first time, depression coexists In a significant percentage.69 All In all, patients with medical conditions are to be considered

as a risk group for nonrecognitlon of concomitant depression.70 This especially applies to elderly Inhibitors,research,lifescience,medical medically ill patients.71 In the other major group of depressed primary care patients, the somatic symptoms complained of very often remain medically unexplained. If one focuses on the mode of presentation, about 50% of the patients report somatic symptoms exclusively, and a minor percentage of some Inhibitors,research,lifescience,medical 20% present their depressive disorder with prevailing psychological, ie, affective and cognitive symptoms.7,21,72,73 There is not, however, a categorical

split between a somatic mode of presentation on the one hand and a psychological mode on the other. Rather, a broad spectrum of transition must be assumed, and the grading of somatization has an impact on the probability of recognition of an underlying depression.25 As a rule, primary care physicians do not recognize a depression with an individual patient better when he or she is Drug_discovery complaining of many actual medically selleck chem unexplained somatic symptoms (here they rather prefer a diagnostic standpoint of wait and see), but when the patient returns again and again to consult because of these symptoms.74 In addition, the extent of hypochondriacal worries and health anxieties facilitate, a correct diagnosis of depression.75,76 Patients with somatic complaints that are not explained medically in an adequate way, however, do not represent a uniform group regarding diagnostic categorization.
