RESUMO
Our objective was to assess the effects of nortriptyline on electroencephalographic sleep and subjective sleep quality in spousally bereaved, depressed elders. Ten elderly volunteers with bereavement-related major depression had electroencephalographic sleep studies while depressed, after remission of depressive symptoms while still taking nortriptyline, and after nortriptyline discontinuation. Changes in sleep measures over time were compared both within bereaved subjects and with age- and sex-matched healthy controls. Remission of depressive symptoms while still on nortriptyline was associated with improvements in sleep quality (P < .002), rapid eye movement (REM) percent (P < .02), REM latency (P < .05), REM density (P < .05), and delta sleep ratio (P < .05). After discontinuation of nortriptyline, REM percent, REM latency, and delta ratio reverted to pretreatment levels, while sleep efficiency and sleep quality continued to show improvement coincident with sustained clinical remission. These data suggest that nortriptyline may be clinically useful in treating the sleep disturbance of elders with bereavement-related depression and that a double-blind, placebo-controlled, randomized clinical trial is warranted.

Among 547 elderly inpatients grouped by DSM-III-R axis I diagnoses, the diagnostic rate of comorbid personality disorder varied four-fold, from 6% in patients with an organic mental disorder to 24% in those with major depression. The previously reported low prevalence of comorbid personality disorder in geriatric patients may be due to its lower rate of diagnosis among patients with organic mental disorders.

Spousal bereavement in late life frequently leads to major depression. However, many people suffer from "minor" depressive symptoms that entail considerable suffering even in the absence of syndromal major depression. We describe longitudinal electroencephalographic (EEG) sleep and clinical evaluations in 14 elderly, recently spousally bereaved subjects who were experiencing subsyndromal depressive symptoms. While subjects did not meet diagnostic criteria for syndromal major depression, they did have mildly elevated scores on the Hamilton Rating Scale for Depression (mean = 10.6, range = 8-16) at the time of initial sleep studies (T1), which were carried out, on average, 5.5 months after loss of the spouse. Entry into the study was limited to volunteers who did not have a personal history of major depression or psychiatric disorder. Twelve subjects underwent followup clinical and EEG sleep evaluations (T2), 9.9 months after spousal loss. Fifty percent continued to show depressive symptoms at 6-month followup. Test-retest comparisons of sleep and clinical measures were made with a group of sex- and age-matched control subjects who were neither bereaved nor depressed. EEG sleep measures did not significantly correlate with time from loss of spouse, severity of depressive symptoms, or subjective sleep quality. Analysis of variance with repeated measures detected a significant group X time interaction effect for delta sleep ratio (decreasing in controls but increasing in the bereaved).

BACKGROUND: The aim of this study was to generate preliminary data on the clinical efficacy of nortriptyline in bereavement-related depression in late life. METHODS: Data are presented on 13 patients (5 men, 8 women), ranging in age from 61 to 78 years (mean = 71.1). Mean time from spousal loss to the beginning of treatment was 11.9 months (range 2-25). Subjects were required to meet Research Diagnostic Criteria for syndromal current major depression and to have a stable Hamilton Rating Scale for Depression (HAM-D) score of greater than or equal to 15. Ten of the 13 volunteers were experiencing their first lifetime episode of major depression. Patients were treated with nortriptyline (mean dose = 49.2 mg/day; mean steady-state level = 68.1 ng/mL). Ratings performed at base-line and weekly during therapy were used to assess symptomatology, intensity of grief, level of functioning, social support, physical impairment, and medication side effects. RESULTS: Pretreatment HAM-D ratings average 22.1 +/- 3.6; posttreatment, 7.2 +/- 2.8, representing a 67.9% decrease. All other rating scales showed significant clinical improvement, except the Texas Revised Inventory of Grief (a measure of grief intensity) (pretreatment, 51.4 +/- 7.3; posttreatment, 46.6 +/- 6.9, only a 9.3% decrease). CONCLUSIONS: These results suggest that nortriptyline is associated with significant symptomatic improvement in all areas of bereavement-related depression except continued intensity of grief after a median treatment interval of 6.4 weeks. This study indicates the need for a controlled clinical trial to determine the placebo response rate, the relapse rate after discontinuation of medication, and the value of combination therapy (using both pharmacotherapy and psychotherapy).
