Moderate-Intensity Exercise and Self-rated Quality of Sleep in Older Adults: A Randomized Controlled Trial

Abstract: Objective. —To determine the effects of moderate-intensity exercise training on self-rated (subjective) sleep quality among healthy, sedentary older adults reporting moderate sleep complaints. Design. —Randomized controlled trial of 16 weeks' duration. Setting. —General community. Participants. —Volunteer sample of 29 women and 14 men (of 67 eligible subjects) aged 50 to 76 years who were sedentary, free of cardiovascular disease, and reported moderate sleep complaints. No participant was withdrawn for adverse effects. Intervention. —Randomized to 16 weeks of community-based, moderate-intensity exercise training or to a wait-listed control condition. Exercise consisted primarily of four 30- to 40-minute endurance training sessions (low-impact aerobics; brisk walking) prescribed per week at 60% to 75% of heart rate reserve based on peak treadmill exercise heart rate. Main Outcome Measure. —Pittsburgh Sleep Quality Index (PSQI). Results. —Compared with controls (C), subjects in the exercise training condition (E) showed significant improvement in the PSQI global sleep score at 16 weeks (baseline and posttest values in mean [SD] for C=8.93 [3.1] and 8.8 [2.6]; baseline and posttest values for E=8.7 [3.0] and 5.4 [2.8]; mean posttest difference between conditions=3.4; P Conclusions. —Older adults with moderate sleep complaints can improve selfrated sleep quality by initiating a regular moderate-intensity exercise program.

Restless legs syndrome

Abstract: In the past 10 years, restless legs syndrome (RLS) has gained recognition as a common sleep disorder. There are several therapeutic options in treating patients with RLS. RLS causes significant sleep disturbance and negatively impacts on patient quality of life. Pharmacologic treatment can result in improved sleep and quality of life issues. RLS patients should be evaluated for iron deficiency anemia; iron replacement in deficient patients may lead to a resolution of symptoms or may reduce the severity of their symptoms. For patients with daily symptoms, the initial therapy is dopamine agonists. Low doses given in the evening or 2 hours before bed provide adequate relief of symptoms for many RLS patients. Augmentation can be seen with all dopamine agents, but is most prevalent with levodopa. Levodopa therapy is best used for milder intermittent symptoms or in aggravating situations, such as long car rides. Opiates and antiepileptics remain a beneficial therapy for RLS and are useful in patients who experience pain as part of their RLS. Newer anticonvulsants may provide additional treatment options, but they have yet to undergo clinical trials. Intravenous iron also may provide relief of RLS symptoms; however, dosing and safety issues have not been fully evaluated in a RLS population.

The Role of Sleep in Emotional Brain Function

Abstract: Rapidly emerging evidence continues to describe an intimate and causal relationship between sleep and emotional brain function. These findings are mirrored by long-standing clinical observations demonstrating that nearly all mood and anxiety disorders co-occur with one or more sleep abnormalities. This review aims to (a) provide a synthesis of recent findings describing the emotional brain and behavioral benefits triggered by sleep, and conversely, the detrimental impairments following a lack of sleep; (b) outline a proposed framework in which sleep, and specifically rapid-eye movement (REM) sleep, supports a process of affective brain homeostasis, optimally preparing the organism for next-day social and emotional functioning; and (c) describe how this hypothesized framework can explain the prevalent relationships between sleep and psychiatric disorders, with a particular focus on posttraumatic stress disorder and major depression.
