This study examines the concept of neurasthenia in a longitudinal cohort of young adults selected from a community sample of the canton of Zurich, Switzerland. The major focus is on the validity of the case definition of neurasthenia. Close approximations of the proposed descriptive and research definitions of the ICD-10 are employed as well as the concept of 'irritable weakness' as described in 1831 by Kraus (1926-1932). The prevalence of neurasthenia defined according to the ICD-10 criteria was: 1% across 10 years and 0.9% in 1988 for a duration criterion of > or = 3 months; and 8.1% across 10 years and 12% in 1988 for a duration criterion of > or = 1 month. The duration criterion of > or = 3 months appeared to be excessively restrictive to represent individuals with neurasthenia in the community. Subjects with 1 month episodes of neurasthenia exhibited sufficient differences from controls and similarities to subjects with anxiety or depressive disorders to justify a 1 month duration criterion for neurasthenia in community samples. The clinical significance of neurasthenia was indicated by the magnitude of subjective distress, and occupational and social impairment reported by the majority of the cases. Prospective assessment of the longitudinal course of neurasthenia revealed that approximately 50% of the cases continued to exhibit this disorder at follow-up. Our findings suggest that neurasthenia is equally likely to represent an early manifestation of affective illness as it is a consequence in those neurasthenic subjects who exhibited comorbid affective disorders. The magnitude, chronicity, impairment, longitudinal stability and distinction from anxiety and depression associated with this condition in the general population, suggest that neurasthenia is an important diagnostic entity for which additional validation studies should be undertaken.

Body dysmorphic disorder (BDD), also known as dysmorphophobia, consists of a distressing and impairing preoccupation with an imagined or slight defect in appearance. BDD is an underrecognized and relatively common disorder that is associated with high rates of occupational and social impairment, hospitalization, and suicide attempts. BDD is unlikely to simply be a symptom of depression, although it often coexists with depression and may be related to depression. It is important to recognize BDD in depressed patients, because missing the diagnosis can result in refractory BDD and depressive symptoms. Available data indicate that BDD may not respond to all treatments for depression and may instead respond preferentially to serotonin-reuptake inhibitors. In addition, lengthier treatment trials than those required for depression may be needed to successfully treat BDD and comorbid depression. It can be difficult and challenging to diagnose BDD in depressed patients because the symptoms are often concealed due to embarrassment and shame. This paper discusses the relationship between BDD and depression and discusses practical strategies for recognizing and treating BDD and depressive symptoms in patients with depression.

This article describes the long-term course of anxiety disorders based on the findings of the Harvard/Brown Anxiety Research Program (HARP) study--a prospective, naturalistic, longitudinal study of patients with anxiety disorders. Data from the HARP study emphasize both the chronicity of anxiety disorders and their frequent psychiatric comorbidity with other anxiety disorders and depression. Social phobia and generalized anxiety disorder are more chronic than panic disorder, although the latter has higher rates of relapse following recovery. Anxiety disorders have a major impact on the everyday lives of sufferers. The detrimental effects on social, psychological, and physical functioning are comparable with other chronic medical and psychiatric conditions, including diabetes, heart disease, and depression. Comorbidity with depression significantly increases the probability of suicide and is associated with poorer outcome. Findings from the HARP study have significant implications for treatment, which currently tends to focus on short-term outcomes. Future studies should emphasize the role of preventive pharmacotherapy to improve the long-term course of anxiety and to reduce its associated suffering, suicide, and occupational and social impairment.

Depression is a common illness which affects some 3% of the population per year. At least 25% of those with marked depression do not consult their general practitioner and in half of those who do the illness is not detected. Depression is easy to recognize when four or five of the core symptoms have been present for 2 weeks which often coincides with some occupational and social impairment. The core symptoms are depressed mood, loss of interest or pleasure, loss of energy or fatigue, concentration difficulties, appetite disturbance, sleep disturbance, agitation or retardation, worthlessness or self blame and suicidal thoughts. A diagnosis of depression is made when five of these core symptoms, one of which should be depressed mood or loss of interest or pleasure, have been present for 2 weeks. Four core symptoms are probably sufficient. Response to antidepressants is good in those with more than mild symptoms. When there are only few or very mild depressive symptoms evidence of response to antidepressants is more uncertain. Antidepressants are effective, they are not addictive and do not lose efficacy with prolonged use. The newer antidepressants have fewer side effects than the older tricyclics, they are better tolerated and lead to less withdrawals from treatment. They are less cardiotoxic and are safer in overdose. Antidepressants should be used at full therapeutic doses. Treatment failure is often due to too low a dose being used in general practice. It may be difficult to reach the right dose with the older tricyclics because of side effects. To consolidate response, treatment should be continued for at least 4 months after the patient is apparently well. Stopping the treatment before this is ill-advised as the partially treated depression frequently returns. Most depression is recurrent. Long-term antidepressant treatment is effective in reducing the risk of new episodes of depression and should be continued to keep the patient well.
