Eighteen patients over the age of 60 who were experiencing a major depressive episode were studied on a Clinical Research Unit after they had been drug-free for at least two weeks. All-night electroencephalographic (EEG) recordings revealed considerable fragmentation of sleep, a mean sleep efficiency of 58 percent, and very little delta sleep. The findings of reduced sleep time, shortened REM latency, and high REM density were similar to those in depressed patients under the age of 60. These preliminary findings support the application of EEG sleep recordings as a tool for the differential diagnosis of depression in the elderly.

The depressed elderly have the highest suicide risk of any group in our society. Thus, depression in late life is a serious mental health problem. The essential goal of the diagnostic work-up is to distinguish a major depressive episode from less severe dysphoric symptoms. The major treatment modalities are properly selected pharmacologic agents, electroconvulsive therapy, psychotherapy and counseling, increased physical and social activity, and attention to underlying medical problems.

Nineteen patients, each hospitalized with a major depressive episode, were deprived of sleep for one night. Ten patients responded with clear improvement in depressive symptoms; the substantial clinical change was transient, usually lasting one day. Those who responded had significantly higher initial depression ratings (P less than .01) and tended to be older than nonresponders who experienced mild increases in irritability, fatigue, and discomfort following sleep deprivation. Amine metabolites, 5-hydroxyindoleacetic acid (5HIAA), and homovanillic acid (HVA) were not substantially affected by sleep deprivation, although there was a significant interaction of clinical response and direction of 3-methoxy-4-hydroxyphenylglycol (MHPG) change. Sleep deprivation thus produces acute, but only transient improvement in a selected group of severely depressed patients; it appears to be an important tool in the study of the affective disorders.

Whilst tricyclic antidepressants are efficacious in all depressive syndromes, classical MAO-inhibitors differ substantially from them in their action. They are considered less effective in general and not very effective in endogenous depression, but recommended for the treatment of 'atypical' depression. A new class of RIMA (Reversible Inhibitors of MAO-A) represented by moclobemide requires a change in clinical thinking on antidepressants. Moclobemide shows the same efficacy in depression as tricyclics: its effects are similar in unipolar and bipolar affective disorders, and in patients with major depressive episode superimposed on dysthymia (double depression). As with classical antidepressants, the response rate tends to be lower, but is still present in psychotic depression. Agitated depressives do not respond less well than non-agitated patients to moclobemide. Patients meeting DSM-III-R criteria for major depression with melancholia tend to respond better than non-melancholics, but this may be associated with the significantly higher baseline severity observed in melancholics. A slightly higher response rate in patients without concomitant benzodiazepine treatment, compared to those with benzodiazepine comedication, may also be related to baseline differences in the severity of depression. Elderly depressives respond less well than younger patients to classical antidepressants, but with moclobemide, elderly patients do as well as younger ones.

The objective of this study was to determine if moclobemide is an effective treatment for depression and if it is well tolerated by patients. A randomized, double-blind placebo-controlled trial was conducted in a tertiary ambulatory clinic which treats depression. Fifty-five patients participated. They fit the DSM-III-R criteria for major depressive episode, scored at least 18 on the 17 item Hamilton Rating Scale for Depression (HRSD), were between the ages of 18 and 65, and were not suffering from a major medical illness. After a one week washout period, patients were randomly selected to receive placebo, amitriptyline or moclobemide for up to six weeks. Moclobemide is a well-tolerated medication at therapeutic doses; it is globally as effective as amitriptyline in the treatment of major depression.

This article provides a brief overview of the changing nature of the concept of minor depression. It then discusses treatment studies conducted from 1980 to 1991 of patients diagnosed as neurotic depression, depressive neurosis or dysthymia, characterologic depression, "double depression" and minor depression or dysthymia, if there has been a full remission of a major depressive episode lasting at least six months prior to the development of dysthymia. Long-term treatment of chronic depression is also reviewed. Cognitive-behavioral intervention and marital therapy have been reported beneficial for patients diagnosed as having neurotic depression, characterological depression, or dysthymia. All studies of antidepressant drug treatment showed drugs to be efficacious and superior to placebo, with few differences found between drugs. In addition, they all showed the importance of analyzing the interactions between treatment and severity or diagnosis. Patients diagnosed as "double depression" also appear responsive to both psychosocial intervention and drug treatment; in general, however, these patients tend to have a poor long-term outcome and continued treatment is indicated. The most obvious finding to emerge from this review is that the diagnosis of minor depression is ambiguous, in large part because of the lack of defining criteria related to severity and course. The review also revealed that in addition to poorly defined subgroups, many studies lacked controls, had small sample sizes, inadequate and/or inconsistent measures of outcome, and limited follow-up. For these reasons, their findings cannot be considered conclusive. Finally, the literature revealed a dearth of controlled studies of psychosocial treatment for well defined subgroups of neurotic depression.

In a 7-week prospective multicentre study, the efficacy, tolerability and safety of moclobemide were compared to those of amitriptyline and placebo in parallel groups of out-patients (n = 173) fulfilling the DSM III-R criteria for a major depressive episode. Participants were required to have a minimum baseline total score of 18 on the 17-item Hamilton Depression Rating Scale (HAMD). After a 1-week placebo washout, patients were randomly allocated to the three treatment groups. Assessment of efficacy, as judged by the number of responders achieving a 50% reduction in HAMD score by the end of treatment, showed that both moclobemide and amitriptyline were significantly superior to placebo, but that they were not significantly different from each other. Both treatments differed significantly from placebo with respect to the Physician's Global Assessment of Efficacy ('very good' or 'good' response: moclobemide 57%, amitriptyline 60% and placebo 35%). Assessment of tolerance as judged by the spontaneous reporting of adverse events showed a significant superiority of moclobemide over amitriptyline, but there was no significant difference between moclobemide and placebo. At termination of the study, amitriptyline patients showed a significant elevation of heart rate both supine (10.8 beats/min) and standing (15.5 beats/min), as well as significant weight gain (1.7 kg), but no changes were seen in the moclobemide or placebo groups. In conclusion, both moclobemide and amitriptyline were found to be more effective than placebo in the treatment of depression, while moclobemide had fewer side effects.

The Calgary Depression Scale (CDS) is a nine item structured interview scale, in which each item has a four point measure, each point anchored by descriptors. The scale has been specifically developed to assess depression in schizophrenics. This article describes the testing of the reliability and validity of the CDS. The scale is assessed and compared to three established measures, the Hamilton Depression Rating Scale (HDRS) the Beck Depression Inventory (BDI) and a depression measure derived from the Brief Psychiatric Rating Scale (BPRS). Confirmatory factor analysis demonstrated that the CDS is unidimensional, measuring the same construct in both in- and outpatients. The scale has high internal consistency, significant strong correlations with scores on the Hamilton, Beck and BPRS depression measures, and the presence of a major depressive episode. All items of the CDS significantly discriminate between the presence and absence of a major depressive episode. It is concluded that the CDS is a parsimonious reliable scale which is suitable for assessing depression across both the acute and residual stages of schizophrenia.

Twenty-nine per cent of patients hospitalized following their first myocardial infarction (MI) are depressed. This percentage decreases with time to 15 per cent at six weeks, and fluctuates between 10 and 13 per cent at three and six months post-MI, respectively. This literature review indicates that exercise training programs are not the treatment of choice to reduce severe post-MI depression. However, in moderately depressed MI patients, their sense of humor is improved, especially if the exercise component involves some degree of socialization and counselling. The lack of significant findings may be compounded by other factors such as incorporating other life-style modifications, the patients' expectations and self-efficacy, and the type of measurement utilized to detect changes in depression levels over time. The type of depression scale used in most studies, the Minnesota Multiphasic Personality Inventory (MMPI), may also be incorrect for MI patients, since the etiology of post-MI depression varies from minor depression to a major depressive episode. The MMPI was developed for use with persons with psychiatric illness. Post-MI depression is considered a normal "uncomplicated bereavement" for the majority of patients. The optimal method used to identify post-MI depression following hospitalization seems to be observation and interview. This is essential to pinpoint the symptoms characteristic of uncomplicated bereavement.

We studied 26 inpatients (17 females; mean age +/- SD: 41.2 +/- 14.3 years) who met the DSM III criteria for a major depressive episode and had a mean (+/- SD) Hamilton Depression Score of 19.3 +/- 8.0. All patients were drug free and medically healthy at the time of experimentation. We found a significant correlation between the CD4/CD8 ratio and the Hamilton Anxiety Score (r = 0.57, p less than 0.005). When splitting our sample in dexamethasone suppression test suppressors (DST-S) and nonsuppressors (DST-NS), this relationship appeared only in DST-NS (DST-NS: r = 0.81, p less than 0.005; DST-S: r = 0.20, p = NS). These results are discussed in terms of heterogeneity among major depressive disorders and possible relationships between catecholaminergic activity and the immune system.
