The purpose of the present study was to evaluate the relationship between sleep disturbances and depression in the Japanese elderly. Methods: These investigations in the Japanese elderly were carried out with the Geriatric Depression Scale, the Pittsburgh Sleep Quality Index, and questions on restless legs syndrome and nocturnal eating disorder. A total of 2023 people (male: 1008; female: 1015; average age: 74.2 ± 6.3 years) were analyzed by c 2 test and simple and multiple logistic regression. The prevalence of sleep disturbance was 37.3% and that of depression was 31.3%. Female gender and/or older ( ≥ 75 years) age were significantly associated with depression. Characteristics in depressive elderly were poor sleep efficiency, sleep disturbances due to difficulty of initiating sleep (DIS), breathing discomfort, coldness and pain, poor subjective sleep quality and lack of enthusiasm for activities. Sleep disturbances due to using the bathroom, breathing discomfort and coldness and long sleep latency were associated with depression in younger (65-74 years) men. Sleep disturbance due to DIS was associated with depression in older ( ≥ 75 years) men. Sleep disturbance due to pain was associated with depression in younger and older women. Poor sleep efficiency was associated with depression in older women. Poor subjective sleep quality was associated with depression in younger and older men and younger women. Lack of enthusiasm was associated with depression in younger and older men and older women. Restless legs syndrome was statistically significantly associated with depression in younger men. It is concluded that sleep disturbance and depression among the Japanese elderly are closely related symptoms. The features of sleep disturbance with depression differed with sex and age.
Nocturnal eating/drinking disorder (NE/DS) is a rare syndrome that includes disorders of both eating and sleeping. It is characterized by awakening in the middle of the night, getting out of bed, and consuming large quantities of food quickly and uncontrollably, then returning to sleep. This may occur several times during the night. Some patients are fully conscious during their nocturnal eating, while some report total amnesia. The aetiology of NE/DS is still unclear, and there is no satisfactory treatment. Four patients with NE/DS are described. Treatment with a selective seroronin reuptake inhibitor (SSRI) was effective in controlling their episodes of nocturnal eating. To our knowledge, this is the first published case report of successful treatment with SSRIs in NE/DS.
Pericardial effusion has recently been reported as a complication of anorexia nervosa. A distinct pathophysiological cause of it could not be revealed. In some reports, there was a probable correlation between weight gain and reduction of pericardial effusion in anorexia nervosa cases. We encountered a case in which pericardial effusion remitted completely along with body weight increase and normalization of low T3 syndrome. These findings suggest that the reduction of pericardial effusion may correlate with both weight gain and low T3 normalization. Plasma brain natriuretic peptide (BNP) levels were increased in this case despite heart failure, and plasma BNP decreased as pericardial effusion remitted. The measurement of serum BNP level may be a clinical parameter in such a case of pericardial effusion.
