Acute efficacy of ECT in the treatment of major depression in the old-old.

OBJECTIVE: There are few data addressing the outcome of ECT for persons over 75 years of age. In a prospective, multisite study, the authors compared characteristics and treatment outcomes of adult (59 and younger), young-old (60 to 74 years), and old-old (75 and older) patients treated with ECT for major depression. METHOD: At four hospitals, 268 patients with primary unipolar major depression and scores of at least 20 on the 24-item Hamilton Depression Rating Scale were treated with suprathreshold right unilateral or bilateral ECT in a standardized manner. Demographic variables, clinical characteristics, and short-term outcomes of the three groups were compared. RESULTS: The demographic and clinical characteristics of the old-old patients were similar to those of the young-old patients, whereas both groups differed from the adult patients on these variables. Both older groups had significantly greater burdens from physical illness and global cognitive impairment at baseline than the adult subjects. Both older groups had shorter index depressive episodes and were less likely to have had inadequate responses to adequate medication trials before ECT. The older groups had higher seizure thresholds, but the three groups received similar courses of treatment. The adult patients experienced a significantly lower rate of ECT response (54%) than the young-old patients (73%), while the old-old patients had an intermediate rate of response (67%). CONCLUSIONS: Despite a higher level of physical illness and cognitive impairment, even the oldest patients with severe major depression tolerate ECT in a manner similar to that for younger patients and demonstrate similar or better acute response.

PET imaging of serotonin type 2A receptors in late-life neuropsychiatric disorders.

OBJECTIVE: To determine whether there are abnormalities in the in vivo status of the serotonin type 2A (5-HT2A) receptor in late-life depression and Alzheimer's disease, the authors used positron emission tomography (PET) to assess patients with these two conditions and healthy subjects. METHOD: PET was performed by using [18F]altanserin to evaluate 5-HT2A receptor binding in 11 elderly patients with depression (four men, seven women; mean age = 65.0 years, SD = 5.5); nine Alzheimer's disease patients, including three with concurrent depression (two men, seven women; mean age = 69.7 years, SD = 5.0); and 10 age-matched healthy subjects (four men, six women; mean age = 69.8 years, SD = 5.0). Partial-volume correction of regional specific binding estimates was performed by using a method based on magnetic resonance imaging. RESULTS: No significant abnormalities in [18F]altanserin binding (binding potential) were observed in the patients with late-life depression, and no effect of depression on binding potential was present within the Alzheimer's disease group. However, the patients with Alzheimer's disease had significantly lower binding than the normal subjects in several brain regions, including the anterior cingulate, prefrontal cortex, and sensorimotor cortex. CONCLUSIONS: These results suggest that the 5-HT2A receptor is differentially affected in late-life depression and Alzheimer's disease, a finding that has implications for the etiological basis of mood and cognitive features of neuropsychiatric disorders of late life.

Treatment of bereavement-related major depressive episodes in later life: a controlled study of acute and continuation treatment with nortriptyline and interpersonal psychotherapy.

OBJECTIVE: The authors tested the hypothesis that nortriptyline and interpersonal psychotherapy, alone and in combination, are superior to placebo in achieving remission of bereavement-related major depressive episodes. METHOD: Eighty subjects, aged 50 years and older, with major depressive episodes that began within 6 months before or 12 months after the loss of a spouse or significant other were randomly assigned to a 16-week doubleblind trial of one of four treatment conditions: nortriptyline plus interpersonal psychotherapy (N = 16), nortriptyline alone in a medication clinic (N = 25), placebo plus interpersonal psychotherapy (N = 17), or placebo alone in a medication clinic (N = 22). The protocol required that the acute-phase double-blind treatment be ended after 8 weeks if Hamilton depression scale ratings had not improved by 50%. Remission was defined as a 17-item Hamilton scale score of 7 or lower for 3 consecutive weeks. RESULTS: The rate of remission for nortriptyline plus interpersonal psychotherapy was 69% (N = 11); for medication clinic, nortriptyline, 56% (N = 14); for placebo plus interpersonal psychotherapy, 29% (N = 5); and for medication clinic, placebo, 45% (N = 10). In a generalized logit model, there was a significant effect of nortriptyline over placebo but no interpersonal psychotherapy effect and no nortriptyline-by-interpersonal psychotherapy interaction. Rates of all-cause attrition were lowest in the nortriptyline plus interpersonal psychotherapy group. CONCLUSIONS: Nortriptyline was superior to placebo in achieving remission of bereavement-related major depressive episodes. The combination of medication and psychotherapy was associated with the highest rate of treatment completion. These results support the use of pharmacologic treatment of major depressive episodes in the wake of a serious life stressor such as bereavement.

Cerebral glucose metabolic response to combined total sleep deprivation and antidepressant treatment in geriatric depression.

OBJECTIVE: The treatment of geriatric depression is complicated by a variable and delayed response to antidepressant treatment. The present study was undertaken to test the hypothesis that combined total sleep deprivation and paroxetine treatment would produce a persistent reduction in glucose metabolism in the anterior cingulate cortex similar to that reported after long-term antidepressant treatment. METHOD: Six elderly depressed patients who met the DSM-IV criteria for major depressive disorder and six age-matched comparison subjects underwent serial positron emission tomography (PET) studies at baseline, after total sleep deprivation, after recovery sleep (after the initial paroxetine dose), and after 2 weeks of paroxetine treatment (patients only). The PET data were analyzed by using statistical parametric mapping methods. RESULTS: The patients' scores on a 13-item version of the Hamilton Depression Rating Scale were decreased after total sleep deprivation, after recovery sleep, and after 2 weeks of treatment. The Hamilton depression scores of the comparison subjects were not significantly altered. In the patients, the greatest reductions in normalized, relative glucose metabolism after sleep deprivation were observed in the anterior cingulate cortex (Brodmann area 24), and they persisted after recovery sleep and antidepressant treatment. The comparison subjects demonstrated increased metabolism in these areas. CONCLUSIONS: Improvement in the patients' depressive symptoms was accompanied by reduced glucose metabolism in the right anterior cingulate cortex and right medial frontal cortex. These preliminary data indicate that in elderly depressed patients, total sleep deprivation may accelerate the clinical and glucose metabolic response to antidepressant treatment.

Three-year outcomes of maintenance nortriptyline treatment in late-life depression: a study of two fixed plasma levels.

OBJECTIVE: This study compared the long-term efficacy of two fixed plasma levels of nortriptyline in preventing or delaying recurrence of major depression in elderly patients and in minimizing residual depressive symptoms and somatic complaints. METHOD: The authors randomly assigned 41 elderly patients with histories of recurrent major depression to 3-year, double-blind maintenance pharmacotherapy using nortriptyline, with controlled plasma concentrations of 80-120 ng/ml versus 40-60 ng/ml. The authors compared times to, and rates of, recurrence of major depression. They also compared frequencies of side effects, noncompliance episodes, and subsyndromal symptomatic flare-ups. RESULTS: Major depressive episodes recurred for six (29%) of 21 subjects in the 80-120-ng/ml condition and eight (40%) of 20 subjects in the 40-60-ng/ml condition, a nonsignificant difference. Most recurrences took place in the first year of maintenance treatment. Hamilton depression scores in the subsyndromal range (higher than either 10 or 7) occurred significantly more often at 40-60 ng/ml, while constipation occurred significantly more often at 80-120 ng/ml. The proportions of patients reporting missed doses did not differ. CONCLUSIONS: Maintenance pharmacotherapy with nortriptyline at 80-120 ng/ml is associated with fewer residual depressive symptoms, that is, a less variable long-term response, than pharmacotherapy at 40-60 ng/ml, but constipation is more frequent and there is no difference in recurrence of syndromal major depressive episodes. Treatment at 80-120 ng/ml may be preferable, because of fewer residual symptoms and less variability of response, as long as side effect burden can be managed successfully.

Depression and aging: a look to the future.

Geriatric depression is widespread, affecting at least one of six patients treated in general medical practice and an even higher percentage in hospitals and nursing homes. Depression in later life has serious consequences, including patients' and caregivers' distress, amplification of disability associated with medical and cognitive disorders of later life, increased health care costs, and increased mortality related to suicide and medical illness. Despite the numerous pathways to late-life depression, as well as the complex medical and psychosocial context in which it occurs, it can be effectively diagnosed and treated. To meet the public health challenges posed by geriatric depression over the next 15 years, the major priorities for research and clinical practice must include improvement in recognizing and treating depression among elderly patients seen in the general medical sector, suicide prevention among elderly patients seen in primary care, and acceleration of response to antidepressants. Other major priorities include improving the early recognition of treatment resistance in late-life depression and developing strategies for improving the treatment response of such patients; finding maintenance treatments with long-term efficacy, especially for patients over age 70 and those who have required electroconvulsive therapy; and developing preventive strategies to reduce the liability to late-onset depression.

Accelerating antidepressant response in geriatric depression: a post hoc comparison of combined sleep deprivation and paroxetine versus monotherapy with paroxetine, nortriptyline, or placebo.

Speed of response is an important clinical issue in the treatment of depressed elderly patients. Our objective was to compare rapid response rates in a study combining therapeutic sleep deprivation (TSD) with paroxetine with two earlier randomized, double-blind studies in late-life depression, one of paroxetine versus nortriptyline and another of nortriptyline versus placebo. We measured depressive symptoms with the 17-item Hamilton Rating Scale of Depression (HRSD), defining rapid response as an HRSD < or = 10 by 2 weeks. With combination therapy (TSD + paroxetine), 9 of 13 patients (69%) experienced a rapid response. In the nortriptyline versus paroxetine study, nortriptyline brought about rapid response in 12 of 37 (32%) and paroxetine in 11 of 43 patients (26%). In the third study, rapid response to nortriptyline occurred in 10 of 41 patients (24%) and to placebo in 6 of 39 patients (15%). The overall chi square, including the rate of rapid response to placebo, was 14.87 (P = .005). The chi square on the four active treatment groups, excluding placebo, was 10.28 (P = .016). This preliminary observation suggests that combined therapy with TSD plus paroxetine may be twice as successful at achieving rapid response in elderly depressed patients than conventional monotherapy with medication or placebo. A prospective, placebo-controlled evaluation of this dual therapy is warranted.

Consensus criteria for traumatic grief. A preliminary empirical test.

BACKGROUND: Studies suggest that symptoms of traumatic grief constitute a distinct syndrome worthy of diagnosis. AIMS: A consensus conference aimed to develop and test a criteria set for traumatic grief. METHOD: The expert panel proposed consensus criteria for traumatic grief. Receiver operator characteristic (ROC) analyses tested the performance of the proposed criteria on 306 widowed respondents at seven months post loss. RESULTS: ROC analyses indicated that three of four separation distress symptoms (e.g. yearning, searching, loneliness) had to be endorsed as at least 'sometimes true' and four of the final eight traumatic distress symptoms (e.g. numbness, disbelief, distrust, anger, sense of futility about the future) had to be endorsed as at least 'mostly true' to yield a sensitivity of 0.93 and a specificity of 0.93 for a diagnosis of traumatic grief. CONCLUSIONS: Preliminary analyses suggest the consensus criteria for traumatic grief have satisfactory operating characteristics, and point to directions for further refinement of the criteria set.

Are age differences in sleep due to phase differences in the output of the circadian timing system?

Our aim was to evaluate whether age-related changes in the phase of the output of the circadian timing system (CTS) can explain age differences in habitual bedtime/wake time and in sleep consolidation parameters. Analyses focused on a group of healthy elderly people (older than 70 years) with no sleep problems and with similar subjective sleep quality as a young control group. The 2-week sleep diary data and 24h laboratory temperature recordings were examined for 70 subjects (22 young men [YM], 19 old men [OM], 29 old women [OW]). Polysomnographic (PSG) sleep data recorded during temperature data acquisition were also available for 62 subjects. These analyses made use of our recently developed technique to demask temperature rhythm data. As expected, compared to the young subjects, older subjects showed earlier habitual bedtime and wake time, more disturbed sleep, and a tendency for an earlier minimum of the circadian temperature rhythm. Despite sleep consolidation differences, the groups showed very similar habitual phase-angle differences (interval between the time occurrence of the fitted temperature minimum and habitual wake time). Both elderly and young subjects woke up on average 3 h after the temperature minimum. After controlling for the effects of age group, habitual bedtime and wake time were related to clock time phase of the circadian temperature rhythm, with an earlier phase associated with earlier habitual bedtime and wake time. None of the sleep consolidation parameters were linked to the temperature phase angle. In conclusion, sleep consolidation changes associated with healthy aging do not appear to be related to changes in the phase-angle difference between the output signal from the CTS and sleep.

Paroxetine in the treatment of primary insomnia: preliminary clinical and electroencephalogram sleep data.

BACKGROUND: Primary insomnia is a persistent and recurrent disorder as well as a risk factor for depression. The goal of this study was to determine whether paroxetine, a nonsedating antidepressant, would be effective in the treatment of patients with primary insomnia. METHOD: Fifteen patients meeting DSM-IV criteria for primary insomnia received paroxetine at bedtime for 6 weeks in an open, flexible-dose trial (median dose = 20 mg). Patients were assessed with daily sleep diaries, baseline and treatment polysomnography, and weekly standardized clinical evaluations. RESULTS: Of the 14 patients who completed the study (1 dropped out owing to side effects), 11 improved with treatment, and 7 of these 11 no longer met diagnostic criteria for insomnia. Although self-reported sleep quality (measured by the Pittsburgh Sleep Quality Index) and daytime well-being (measured by the Profile of Mood States) improved with treatment, the quantity of sleep, measured by diary and by polysomnography, did not change consistently with these improvements. Power spectral analysis suggested that paroxetine treatment may be associated with decreases in power in frequencies within the delta and alpha frequency ranges. CONCLUSION: These results support the effectiveness of paroxetine in the acute treatment of primary insomnia. Further evaluation with controlled and longitudinal designs is warranted.

A double-blind randomized comparison of nortriptyline and paroxetine in the treatment of late-life depression: 6-week outcome.

BACKGROUND: Some studies have suggested that selective serotonin reuptake inhibitors may be less efficacious than tricyclic antidepressants in the treatment of severe depression in older patients. The objective of this study was to compare the 6-week outcome of treatment with nortriptyline and paroxetine in older patients with a major depressive episode. METHOD: A double-blind randomized comparison of nortriptyline and paroxetine was conducted in 80 elderly (mean +/- SD age = 75.0 +/- 7.4 years) psychiatric inpatients and outpatients who presented with a major depressive episode. Dropout and response rates were compared in patients who began or completed treatment. Rates of response of inpatients and patients with melancholic depression were also compared. RESULTS: Over 6 weeks, there were no significant differences in dropout rates due to side effects (nortriptyline, 14% vs. paroxetine, 19%) or for any reason (27% vs. 33%). Similarly, there were no significant differences between the rates of favorable response to nortriptyline or paroxetine (intent-to-treat analysis, 57% vs. 44%; completer analysis, 78% vs. 66%). Analyses restricted to inpatients or to patients with melancholic depression yielded similar results. CONCLUSION: Nortriptyline and paroxetine appear to have similar efficacy and tolerability in the acute (6-week) treatment of older depressed patients, including hospitalized patients and those with melancholic features.

Continuation and maintenance pharmacotherapy in geriatric depression: an open-trial comparison of paroxetine and nortriptyline in patients older than 70 years.

We present preliminary data on the efficacy of paroxetine, as compared with nortriptyline, in preventing or delaying relapse and recurrence of major depression in elderly patients. Following double-blind, acute-phase pharmacotherapy, 25 patients (mean age = 72.5 years) began open-trial continuation treatment with paroxetine (mean dose = 24.5 mg/day), and 15 patients (mean age = 77.5 years) received nortriptyline (mean dose = 51.3 mg/day; mean blood level = 85.5 ng/mL). Over an 18-month period, paroxetine and nortriptyline have shown comparable efficacy in preventing or delaying relapse and recurrence, with 80% to 90% of patients remaining well. These data suggest that paroxetine holds promise for long-term maintenance treatment in patients in their 70s and older with depression; however, further controlled evaluation is necessary.

Cognitive effects of paroxetine in older depressed patients.

This study examined whether paroxetine produces cognitive toxicity in elderly patients suffering from a major depressive episode. Twenty-nine depressed patients with a wide range of cognitive functioning were treated with paroxetine. At baseline and during 6 weeks of treatment, patients were asked to complete various measures of cognitive function and had blood drawn to determine serum anticholinergicity. Measures of attention and cognitive speed showed significant improvement with treatment, while the memory performance remained unchanged. A similar pattern of results was found in both cognitively impaired and intact patients. The slight increase in serum anticholinergicity seen in some elderly patients did not significantly impair cognitive function, even in patients with a preexisting cognitive impairment.

Which elderly depressed patients remain well on maintenance interpersonal psychotherapy alone?: report from the Pittsburgh study of maintenance therapies in late-life depression.

The aim of this study was to identify elderly depressed patients who can remain well on maintenance Interpersonal Psychotherapy (IPT) alone, after discontinuation of antidepressant medication. Using Cox proportional hazards models, increased severity of depression at pretreatment was associated with increased recurrence rates, to an extent greater in patients maintained on monthly IPT than in those maintained on nortriptyline. The long-term response to maintenance IPT was correctly identified in 20/25 cases by a pretreatment Hamilton score of > or = 20. Fourteen of sixteen patients with pretreatment scores of > or = 20 experienced recurrence of major depression on maintenance IPT, while 6/9 patients with pretreatment scores of less than 20 did not. (Fisher exact P = .01). The same pattern of recurrence in relation to severity was not evident in maintenance placebo, nortriptyline, or combination treatment. In addition, Hamilton scores during continuation treatment were lower (< or = 7) among those who remained well on maintenance IPT than among those who had recurrences. Elderly patients whose depressions are milder at baseline and who show excellent symptomatic remission during acute and continuation therapy may be good candidates for monthly maintenance IPT after initial successful treatment with antidepressant medication and psychotherapy.

A double-blind, placebo-controlled assessment of nortriptyline's side-effects during 3-year maintenance treatment in elderly patients with recurrent major depression.

The authors assessed the severity of nortriptyline's side-effects in older patients with recurrent major depression during placebo-controlled, double-blind maintenance therapy. Data were from 37 patients completing 2-3 years of maintenance therapy; 29 were on nortriptyline and eight were on placebo. The authors detected a time-by-treatment interaction for dry mouth (greater in nortriptyline-treated patients), but no increased association of nortriptyline with constipation, weight change or orthostatic symptoms. Heart rate was consistently higher in nortriptyline-maintained patients as compared with placebo. The total 'side-effect' score on the Asberg Rating Scale, as well as complaints of physical tiredness, daytime sleepiness and nocturnal sleep disturbance, were related primarily to residual depression rather than treatment with nortriptyline.

EEG sleep measures in later-life bereavement depression. A randomized, double-blind, placebo-controlled evaluation of nortriptyline.

The authors examined 1) effects of nortriptyline (NT) on electroencephalographic (EEG) sleep measures in elderly patients with bereavement-related depression in remission under randomized, double-blind, placebo-controlled conditions, and 2) the effects of clinical remission on sleep after discontinuation of medication. Subjects were classified as responders to placebo (n = 9) or NT (n = 18) and had EEG sleep studies at three time-points: before treatment (T1), remitted on medication or placebo (T2), and remitted off medication or placebo (T3). As compared with placebo, NT was differentially associated with decreases in REM sleep time and percent and increases in REM sleep density (T2). No changes in EEG sleep measures occurred in placebo responders. REM sleep measures in NT responders reverted to T1 levels after T3, with persistence of robust clinical remission and normal subjective sleep quality. These data suggest that NT alters REM sleep, but that EEG sleep characteristics in bereavement-related depression persist into remission.

Treatment of 70(+)-year-olds with recurrent major depression. Excellent short-term but brittle long-term response.

The authors compared response rates, by age (60-69 vs. 70+), to acute, continuation, and 1-year maintenance depression treatment. Patients (N = 180) received open combined treatment with nortriptyline (NT)/placebo and interpersonal psychotherapy (IPT). Patients who recovered then entered randomized, double-blind maintenance treatment with NT or placebo or received maintenance monthly IPT (combined with NT or placebo). Comparison of time-to-remission and recovery and absolute rates of remission, relapse, recovery, and recurrence yielded similar times to/rates of remission and recovery; however, older patients had far more recurrence during the first year of maintenance therapy. Although responses to acute and continuation treatment with combined NT and psychotherapy were similar, the older group had more recurrence in the first year of maintenance. Continuation of combined medication and psychotherapy may represent the best long-term treatment.
