Anxiety disorders appear to be among the most common psychiatric illnesses of the elderly. Although systematic studies of the phenomenology and treatment of anxiety disorders in the elderly are rather scant, inferences based on studies of younger patients combined with careful clinical observations can be very helpful for both diagnostic and treatment purposes. Several medical conditions can mimic anxiety disorders and suggest a need to consider a possible underlying organic condition during the process of evaluation. Clinical evaluation should be complemented by rating scales and laboratory tests where appropriate. Anxiety disorders occurring for the first time in late life appear to be milder in symptomatology than early-onset disorders. Most anxiety disorders can be well managed using the available treatments. It appears that short-acting benzodiazepines, such as oxazepam and lorazepam, are the treatment of choice for short-term symptoms of geriatric anxiety. For anxiety of longer durations (e.g., greater than 6 months), a nonbenzodiazepine such as buspirone seems preferable. Antidepressants seem effective in cases of mixed anxiety-depression or panic disorder. There is clearly a need, however, to perform more controlled clinical trials of these medications to establish empirically derived guidelines for safety, efficacy, and specificity of these drugs for the elderly population. Finally, nonpharmacologic methods such as cognitive-behavioral treatments can be very effective for the management of certain anxiety disorders, particularly phobias.

178 outpatients were administered to a structured interview evaluating diagnostic, illness history, and sociodemographic data of DSM-III-R anxiety disorders. Patients with panic disorder with agoraphobia were a more severely ill subgroup than patients with panic disorder without agoraphobia. Simple and social phobia had the earliest age at onset, panic disorder the latest age at onset. Conjugal stress was the most frequent event preceding the onset of the anxiety disorders. Female patients showed more severe impairment suffering more frequently from concomitant phobic avoidance, generalized anxiety, and depression compared to male patients.

In the epidemiological Zurich cohort study a syndrome of 'Recurrent Brief Anxiety' (RBA) was identified and operationalized. It had a 1-year prevalence rate of 2.7, males seemed to prevail slightly. RBA was highly associated with 'Recurrent Brief Depression' (RBD) and panic, and to a minor extent with agoraphobia and dysthymia. The family history was positive for depression and anxiety (panic, generalized anxiety disorder). In studies of panic, one should look for the frequently associated syndromes of RBA and RBD.

The impact of different definitions of secondary depression on comorbidity and treatment outcome findings in anxiety disorder patients was examined by reviewing existing studies. Few data were found specifically on alternative definitions of secondary depression. However, other relevant findings yielded several conclusions: (a) different definitions of depression dramatically affect comorbidity findings, (b) widely divergent comorbidity findings are obtained in studies that use the same (temporal) definition of secondary depression, (c) few data exist on how different definitions of depression affect treatment outcome findings for anxiety disorders, and (d) some data show that patients' reports of whether or not their depressive symptoms temporally followed their anxiety symptoms are unreliable, suggesting that investigators who want to study secondary depression need to first determine that they have a reliable way to assess it.

Advances in neuropeptide neurobiology in the last decade are illustrated by studies of corticotropin-releasing factor (CRF), the 41 amino acid-containing peptide that controls the anterior pituitary secretion of adrenocorticotropin and other pro-opiomelanocortin products. Corticotropin-releasing factor is synthesized in both hypothalamic and extrahypothalamic perikarya in a large prohormone form, (186 amino acids), then it is processed and transported to nerve terminals where it is released in its active form by a calcium-dependent mechanism. Corticotropin-releasing factor biosynthesis can now be measured by in situ hybridization because of the elucidation of the CRF gene sequence. Once released, CRF acts on high-affinity CRF receptors, and signal transduction is mediated by activation of adenylate cyclase in certain brain areas, and perhaps by phosphoinositide hydrolysis. In other brain areas CRF is inactivated by peptidases that degrade the hormone, though these are not well characterized. A CRF binding protein has been identified in plasma, and perhaps in brain. Considerable evidence exists from cerebrospinal fluid studies, postmortem tissue receptor measurements, and CRF stimulation test studies to support the hypothesis that CRF is hypersecreted in depression, resulting in both pituitary-adrenal axis hyperactivity and certain signs and symptoms of depression, e.g., decreased libido, insomnia, and decreased appetite. There is also evidence for an involvement of CRF in the pathophysiology of anxiety disorders and in the mechanism of action of benzodiazepines. The development of selective CRF-receptor antagonists will permit direct testing of the hypothesis that CRF hypersecretion is responsible for certain of the cardinal features of affective and anxiety disorders.

This paper examines the association between marital status and psychiatric disorder for Blacks and explores the extent to which these patterns differ from those for Whites. Widowed and separated/divorced Black males and females have higher rates of disorder than the married; never-married Blacks do not have an elevated risk of psychiatric illness. The association between marital status and disorder for White males is similar and stronger than that observed for Blacks. For White women, the separated/divorced have a higher risk of disorder than the married, and unmarried White females have higher rates of the substance abuse disorders, but lower rates of the anxiety disorder than the married. Across all marital status groups, Black males and White males have higher rates of disorder (except for depression), than females. A complex pattern emerges when gender differences in the relative rates of disorder for unmarried Blacks compared to married Blacks are considered. Separated/divorced Black men, widowed Black women, and never-married Black men are worse off than their respective peers. Except for the separated/divorced, opposite patterns are evident for Whites. Directions for further research are outlined.

Since its first recognition, a number of researchers have endeavored to link anorexia nervosa to underlying pathology. For example, in the past, attempts were made to associate anorexia with such psychiatric disturbances as schizophrenia, anxiety disorders, and obsessive-compulsive and antisocial personality disorders. Most recent efforts have focused on the possible link between anorexia nervosa and affective disorders. This article reviews the literature concerned with investigating psychiatric disturbances and genetic variables hypothesized as predisposing factors in the etiology of anorexia nervosa. Particular emphasis is given to research which discusses the association between anorexia nervosa and depression. Psychopharmacological evidence and family genetics studies are reviewed. Suggestions for future research are also made.

The influence of psychiatric risk factors on the development of depression following stroke was examined in 88 patients undergoing inpatient rehabilitation. In this sample, 34 patients (38%) had a diagnosis of major or minor depression. Older age and a personal or family history of affective or anxiety disorder were associated significantly with major depression. Minor depression was more common among males and those patients with greater physical disability. Severity of depressive symptoms was associated with a personal or family history of affective or anxiety disorder and higher pre-stroke personality neuroticism. We conclude that certain psychiatric risk factors for affective disorder are strongly associated with poststroke depression. The implications of these findings for anticipating and managing poststroke depression are discussed.

In a naturalistic study that assessed the lifetime psychiatric histories of 275 children ascertained independently of diagnostic or treatment-seeking behavior, 38 (14%) of the children had a history of anxiety disorder. Rates of comorbidity of depression and other psychiatric disorders were high. Life table estimates of the duration of illness indicate a more protracted time to recover than expected, because 46% would be ill for at least 8 years. Moreover, of those who recovered from their first episode of anxiety disorder, many had experienced recurrence before interview. After conducting pooled analyses, investigators performed separate analyses for children with separation disorder and overanxious disorder. Median age of onset of these conditions was surprisingly young: 10 years of age for overanxious disorder and 8 years of age for separation disorders.

Anxiety and depression are often clinically associated in children, but are very different in term of effect and symptoms. Family studies favor the hypothesis of a common diathesis for these disorders. Parental history of major depressive and/or anxiety disorders increase the risk of mood and anxiety disorders in children. At the present time, biological studies have not determined any biochemical conclusion for these disorders. It should be noted that although imipramine is efficient in both depressive disorder and separation anxiety, this does not implicate a common physiopathologic basis.
