This study examined the strength of relationships between forms of depressive symptoms over a one-year period and the onset of major depression. The data analyzed were collected in 4 sites of the US National Institute of Mental Health Epidemiologic Catchment Area Program (NIMH-ECA, 1981-1985). The Diagnostic Interview Schedule's specifications of DSM-III criteria for major depression were employed. Overall, the results indicated a strong positive association between an onset episode and the following depressive symptoms over 1 year: diminished sexual drive, feelings of worthlessness or excessive guilt and trouble concentrating or thinking. Sleep disturbance among women and fatigue among males were also significantly associated with experiencing an onset of major depression. The implications of the findings for secondary prevention efforts are explored.

Sleep disturbance is a common and frequent complaint reported by tinnitus sufferers. Recent studies have shown that when insomnia and depression are associated with tinnitus there is decreased tolerance and increased discomfort with the tinnitus. The purpose of this study was to assess the reported prevalence and severity of sleep disturbance in chronic tinnitus patients. Patients (n = 80) were military personnel without major psychiatric disturbance and their tinnitus was associated with noise-induced permanent hearing loss (NIHL). Mini Sleep Questionnaire (MSQ) scores for sleep disturbance were found to be higher than those of normal controls in 77% of the patients. Highest MSQ scores in tinnitus patients with a sleep complaint were for delayed sleep, morning awakenings, mid-sleep awakenings, morning fatigue, and chronic fatigue. In contrast, a complaint of excessive daytime sleep (EDS) was not common. The self-rated severity of the tinnitus was greater in subjects with higher sleep disturbance scores. Self-rated depressive symptomatology was also highly correlated with sleep disturbance. Retrospective examination of sleep records and polysomnographic data for 10 patients with a complaint of chronic tinnitus revealed a combined effect for the tinnitus condition when associated with another conventional sleep disorder. In spite of the common complaint of sleep disturbance in tinnitus, only a minority seek a sleep examination.

These studies were performed to clarify (1) the actual conditions concerning rotating shift schedules of nurses in Japanese university and college hospitals and to evaluate (2) some aspects of the physical and mental health, and (3) sleep profile of hospital nurses working on counter-clockwise shift rotation. Two questionnaire surveys and the OSA sleep inventory (OSA) were carried out. The subjects in the study (1) were a total of 80 nursing directors in university and college hospitals. The questionnaire covered 4 categories, such as the schedule most frequently adopted and reasons for using the schedule. The questionnaires were returned by 67 directors (83.8%). The subjects in the study (2) were 189 nurses working on three-shift work schedules at Asahikawa Medical College Hospital. The items in the questionnaire covered 7 categories, as follows: 1) feeling of sleep after each shift (8 items); 2) feeling of fatigue after each shift (30 items); 3) physical symptoms; 4) inter-personal problems; 5) all the items on Zung's self-rating depression scale (SDS); 6) all the items on the Horne and Ostberg morningness-eveningness questionnaire; and 7) 24 items on the Maudsley personality inventory. The questionnaires were returned by 156 nurses (82.5%), whose mean age and duration of shift-work employment were 27.2 +/- 5.1 and 5.0 +/- 4.3 years (mean +/- SD), respectively. For 152 nurses (97.4%) of those returning the questionnaire, the working schedule consisted of 2 consecutive night shifts and 2 consecutive evening shifts, following a variable number of day shifts (rapid and counterclockwise shift rotation). The subjects in the study (3) were 8 healthy nurses working on above-mentioned three rotating shifts at the psychiatric ward of Asahikawa Medical College Hospital, whose mean age was 29.4 +/- 5.8 years (mean +/- SD). All the subjects recorded their sleep-logs and underwent OSA everyday for 30 consecutive days. Of the 240 OSA data, 95 data (16 after day shift, 17 after the 1st night shift, 16 after the 2nd night shift, 15 after the 1st evening shift, 16 after the 2nd evening shift, 15 after day off) were analyzed. In addition to five of sleep factors in the OSA analysis, we evaluated the global score (GS), which represents subjective global feeling of sleep. In the study (1), 47 of 66 hospitals (71.2%) adopted rapid and counterclockwise shift rotation. The results of study (2) were as follows: 1) After the first night shift (diurnal sleep), the sleep problems were worst, and the frequency of taking sleep-inducing drugs was highest (12.6%); 2) Feelings of fatigue were the highest level after each of the two night shifts; 3) SDS score was relatively high (57.8 +/- 8.1, mean +/- SD); 4) The older the nurse, the greater the aggravation of both sleep problems and fatigue; 5) Sleep problems after day shifts were worse and SDS score was higher in nurses classified as "nightowls" compared to those in nurses classified as "morning people"; and 6) There was no difference between introverts and extroverts in sleep problems, fatigue or SDS score. The results of study (3) were as follows: 1) In 3 of sleep factors (Sleepiness, Integrated sleep, sleep initiation) and GS, there were significant differences among each rotating shift schedule including day off; 2) The highest score in five of sleep factors and the highest GS were noted after the 2nd night shift (nocturnal sleep), and the lowest after the 1st night shift (diurnal sleep); and 3) The younger subjects (n = 4; mean age, 24.5 years) showed a higher GS compared with that of the older subjects (n = 4; mean age, 34.2 years).

There is a strong association between the chronic fatigue syndrome and both depressive illness and sleep disturbance, but the efficacy of antidepressants is uncertain. We studied the efficacy and adverse effects of moclobemide in patients with chronic fatigue syndrome, stratifying the sample both by co-morbid major depressive illness and by sleep disturbance. Forty-nine patients with chronic fatigue syndrome were recruited. Patients were given moclobemide up to 600 mg a day for 6 weeks. Four (8%) patients dropped out, three because of adverse effects. Adverse effects wee otherwise mild and transient. On analysing the whole sample, there were significant but small reductions in fatigue, depression, anxiety and somatic amplification, as well as a modest overall improvement. The greatest improvement occurred in those individuals who had a co-morbid major depressive illness, with seven out of 14 (50%) of such individuals rating themselves as "much better" by 6 weeks, compared to six out of 31 (19%) of those who were not depressed (31% difference, 95% CI 1-60%, P = 0.04). Sleep disturbance had no effect on outcome. Moclobemide may be indicated in patients with chronic fatigue syndrome and a co-morbid major depressive disorder. A randomized, placebo-controlled trial is needed to confirm this. These results do not support moclobemide as an effective treatment of chronic fatigue syndrome in the absence of a major depressive disorder.

Cognitive problems are frequently reported in patients with eosinophilia-myalgia syndrome (EMS). This is the first study to explore, in EMS, the relationship between specific neuropsychological deficits and fatigue and pain. Relationships among depression, sleep disturbance, and neuropsychological deficits in EMS were also examined. Neither fatigue nor pain was correlated with memory impairment. Sleep disturbance was significantly correlated with verbal memory impairment, but not with deficits in visuospatial memory. These results suggest that cognitive loss in EMS cannot be attributed to pain or fatigue. Although some aspects of memory impairment may be associated with disturbed sleep, visual memory deficits are clearly independent of sleep deficits and may result from direct effects of the disease on the central nervous system.

The English version of the Arabic Children's Depression Inventory, constructed by Abdel-Khalek, was applied to a sample of 535 U.S. students (11 to 18 years old). Cronbach coefficients alpha were .88, .90, and .89 for boys, girls, and all subjects, respectively. Seven factors were extracted by principal axis factor analysis (Negative mood and self-depreciation, Fatigue, Lack of loneliness, Sleep problems, Weak concentration, Pessimism, and Feeling happy), denoting clear factorial structure; however, the scale was intended to be unidimensional. Sex and racial differences for this American sample were not statistically significant but the correlation of depression scores with age was .22. The scale appears useful in studying depression in American school children and adolescents. Also, cross-cultural differences in childhood depression between samples from Egypt and Kuwait of previous studies and the present American sample were examined. Based on the effect size, female Kuwaiti had a lower mean depression score than either the Egyptian or American groups. The scale can be used in cross-cultural research.

Sleep disturbance is a common and complex clinical problem, particularly in older adults. With advancing age, the normal sleep cycle begins to break down, resulting in a reduction in the deeper stages of sleep and an often-profound increase in the fragmentation of nighttime sleep by periods of intrusive wakefulness. Sleep disorders exacerbate these age-related changes, leading to reports of daytime fatigue, sleepiness, and impaired daily function. The resultant chronic sleep deprivation invariably leads to often-unsuccessful attempts by the patient to overcome the problem. Patients may stay in bed longer, take more naps during the day, or seek out agents that putatively restore normal sleep patterns. Paradoxically, these efforts often result in exacerbation of the sleep disturbance. This review delineates the common causes of disordered sleep in older persons. Further, it reviews effective diagnostic approaches and treatments for these conditions, including limitations of hypnotic medications and melatonin.

Gender symptom differences were studied in 948 subjects with Parkinson's disease (PD) using a questionnaire covering the most common symptoms associated with PD at debut (SP-1) and at present (SP-2). The symptoms most frequently reported by both genders were: tremor, fumblingness, writing problems, rigidity and fatigue. At SP-1 females reported neck-pain and low back pain more frequently than males. At SP-2 subjects reported an increased number of symptoms. The following symptoms were more frequent among males than females: writing difficulties, fumblingness, gait problems, speech problems, increased flow of saliva, lack of initiative. Sleep problems were common in both sexes with inability to turn in bed and calf muscle cramps in a high percentage. A majority of female subjects find their symptoms (e.g. depression) constantly distressing. Although depression is not one of primary reported symptoms (36%) attention is called for, due to the problem with compliance to treatment regimes. About 30% do not report having tremor and rigidity. This study indicates the usefulness of a symptom profile instrument capable of capturing the many symptoms involved in PD. Such an instrument could be used to detect apparent mistakes in medication and thereby increase the function and quality of life for the individual.

Diagnosing depression in cancer patients has been challenging because the diagnostic criteria include somatic symptoms frequently attributed to the cancer itself or its treatment. However, few studies have explored how to appropriately deal with individual somatic symptoms. The authors used data from 220 cancer patients with major depression to examine the intercorrelations among the DSM-IV somatic and nonsomatic symptom criteria as well as whether the presence of an individual somatic symptom could discriminate the severity of major depression. Appetite changes and a diminished ability to think were positively associated with anhedonia. Sleep disturbance and fatigue were not significantly associated with nonsomatic symptoms. These associations were consistent after adjusting for physical functioning and pain. Only patients with appetite changes showed a higher severity of depression. These results suggest that individual somatic symptoms differ in nature and that appetite-related symptoms and a diminished ability to think may be useful for diagnosing depression in cancer patients, whereas sleep disturbances and fatigue may not be as useful.

Sleep problems have been observed during many of the space flights. The existence of poor quality of sleep, fatigue, insomnia or different alterations in sleep structure, organization and sleep cyclicity have been established. Nevertheless results obtained from investigations of human sleep on board manned space vehicles show that it is possible to keep sleep patterns related to the restorative and adaptive processes. For the first time in the frame of the "Intercosmos" program a multi-channel system for recording and analysis of sleep in space was constructed by scientists of the Bulgarian Academy of Sciences and was installed on board the manned Mir orbiting station. In 1988 during the joint Bulgarian-Russian space flight continues recording of electro-physiological parameters necessary to estimate the sleep stages and sleep organization was made. These investigations were continued in next space flights of different prolongation. The results were compared with the findings obtained under the conditions during the pre- and post-flight periods.
