We present polysomnographic data for psychiatrically asymptomatic first-degree relatives of unipolar depressed probands. Relatives were classified by proband rapid eye movement (REM) latency (reduced/nonreduced) and by personal REM latency (reduced/nonreduced). Reduced REM latency relatives, whether defined by the proband or by their own REM latency, had polysomnographic alterations consistent with those found in depressed patients, although none of these relatives was depressed at assessment. Reduced REM latency relatives with a history of unipolar depression were compared to reduced REM latency relatives with no history of depression. Virtually no polysomnographic differences were found. Polysomnographic alterations may be stable antecedents of the onset of depression.

As part of an ongoing study of risk factors for unipolar depression in a high-risk group, we have evaluated cognitive variables documented to be abnormal during an episode of depression in adult first-degree relatives of unipolar depressed probands. Asymptomatic relatives with a history of unipolar depression were compared with relatives who had never been depressed. Despite an extended period of recovery (approximately 8 years), relatives with a history of unipolar depression had more negative moment-to-moment thinking, more dysfunctional attitudes, and were more likely to attribute failure to themselves than relatives with no depression. These findings support the hypothesis that unipolar depression is associated with long-term changes in selected cognitive functioning.

As part of a study of the possible subgroups of unipolar affective disease, 27 families were ascertained as depression spectrum disease (DSD) families. The purpose of this study was an investigation of the linkage relationships between DSD and 30 genetic markers using the robust sib-pair and lod-score methods. Using the sib-pair methods, evidence for linkage was found with orosomucoid (ORM) on chromosome 9q (p = 0.006), regardless of whether only individuals with unipolar depression, alcoholism, or antisocial personality were considered to be affected, or whether individuals with any psychiatric disorder were considered to be affected. Weak evidence of linkage with ORM was corroborated using lod-score methods when a narrow definition of depression spectrum disease was used, although stronger evidence of linkage was found with ORM when any psychiatric disorder was considered to be affected. The maximum lod-score for ORM was 1.68 at a male recombination fraction of 0.23 and a female recombination fraction of 0.01.

Tests the efficacy of social problem-solving therapy for unipolar depression and examines the relative contribution of training in the problem-orientation component of the overall model. This process involves various beliefs, assumptions, appraisals, and expectations concerning life's problems and one's problem-solving ability. It is conceptually distinct from the remaining four problem-solving components that are specific goal-directed tasks. A dismantling research design, involving 39 depressed Ss, provides findings that indicate problem-solving to be an effective cognitive-behavioral treatment approach for depression, thereby extending previous research. Moreover, the results underscore the importance of including problem-orientation training.

Cyclic 48-h unipolar depression is a rare form of recurrent affective disorder. We studied a single patient to determine (a) if there is an association between psychiatric status and migrating motor complex activity; and (b) if phase III of the migrating motor complex is in phase with rapid eye movement sleep in depression. There was marked reduction in phase III of the migrating motor complex during the depressed (n = 7) compared with the euthymic phase (n = 13), and a lack of coherence between phase III migrating motor complex activity and sleep stages in both depressed and nondepressed phases. The depressed state may be associated with altered upper gastrointestinal motor function.

Using positron emission tomography, we studied cerebral glucose metabolism in drug-free, age- and sex-matched, right-handed patients with unipolar depression (n = 10), bipolar depression (n = 10), obsessive-compulsive disorder (OCD) with secondary depression (n = 10), OCD without major depression (n = 14), and normal controls (n = 12). Depressed patients were matched for depression on the Hamilton Depression Rating Scale, and subjects with OCD without depression and OCD with depression had similar levels of OCD without depression and OCD with depression had similar levels of OCD pathology. We also studied six non-sex-matched patients with mania. Mean (+/- SD) glucose metabolic rates for the left dorsal anterolateral prefrontal cortex, divided by the rate for the ipsilateral hemisphere as a whole (ALPFC/hem), were similar in the primary depressions (unipolar depression = 1.05 +/- 0.05; bipolar depression = 1.04 +/- 0.05), and were significantly lower than those in normal controls (1.12 +/- 0.06) or OCD without depression (1.15 +/- 0.05). Results for the right hemisphere were similar. Values in subjects with OCD with depression (1.10 +/- 0.05) were also significantly lower than in subjects with OCD without depression, and values in subjects with bipolar depression were lower than those in manic subjects (1.12 +/- 0.03) on this measure in the left hemisphere, although results were not significant in the right hemisphere. There was a significant correlation between the HAM-D score and the left ALPFC/hem. With medication for depression (n = 12), the left ALPFC/hem increased significantly and the percentage change in the Hamilton scale score correlated with the percentage change in the left ALPFC/hem.(ABSTRACT TRUNCATED AT 250 WORDS)

In this retrospective study the authors determined the efficacy of lithium added to a combined antipsychotic-antidepressant drug regimen in 21 psychotically depressed patients who had been refractory to combined drug treatment. Response to lithium was then compared with response rates of 15 patients to ECT, the established treatment for nonresponsive delusional depression. Lithium was effective in eight of nine patients with bipolar depression but in only three of 12 patients with unipolar depression; ECT was effective in nine of 15 patients with unipolar depression. Lithium augmentation appeared to be a realistic treatment alternative for refractory bipolar patients but was disappointing in unipolar patients.

Fluoxetine is a new antidepressant which enhances serotoninergic neurotransmission through potent and selective inhibition of neuronal reuptake of serotonin. Metabolism by N-desmethylation occurs in man yielding desmethylfluoxetine, which also inhibits serotonin reuptake. Both the parent compound and metabolite possess elimination half-lives of several days facilitating the maintenance of steady-state plasma concentrations during long term treatment. Fluoxetine has overall therapeutic efficacy comparable with imipramine, amitriptyline and doxepin in patients with unipolar depression treated for 5 to 6 weeks, although it may be less effective than tricyclic antidepressants in relieving sleep disorders in depressed patients. Geriatric patients also responded as well to fluoxetine as to doxepin. The symptomatic improvement in patients with unipolar depression during short term fluoxetine treatment has been satisfactorily maintained when therapy was extended for at least 6 months: the relapse rate was low and similar to that of imipramine. Preliminary data have shown that patients with bipolar depression gained similar therapeutic benefit from fluoxetine or imipramine. Other preliminary trials have indicated that fluoxetine may be useful in obsessive-compulsive disorders. Usual doses of fluoxetine cause significantly fewer anticholinergic-type side effects than tricyclic antidepressants. Nausea, nervousness and insomnia are the most frequently reported fluoxetine-related adverse effects, but these have usually not been severe. Therapeutic doses of fluoxetine do not affect cardiac conduction intervals in patients without pre-existing cardiovascular disease and fluoxetine has been relatively safe in the small number of patients who have taken overdoses. It has not been clearly established whether some types of depression may respond more readily to fluoxetine than other antidepressants, and its overall therapeutic efficacy has not been compared with other second generation antidepressants. Thus, with its different and perhaps improved side effect profile compared with older tricyclic antidepressants, fluoxetine offers properties that could be used to advantage in many patients with depression.

Dysfunctional interactions between mothers with major affective disorders and their children may contribute to the children's high risk of disorder. This study investigated the behavior of mothers with recurrent unipolar depression, bipolar disorder, or chronic medical illness and of normal subjects toward their children during a directly observed conflict discussion task. In addition, lifetime history of depression, current mood, and chronic stress were investigated as predictors of maternal interaction. Unipolar depressed women displayed relatively more negative, less positive, and less task-focused behaviour toward their children. Current mood and chronic stress, more than psychiatric history, contributed to the prediction of interaction style.
