Bright light therapy: improved sensitivity to its effects on rest-activity rhythms in Alzheimer patients by application of nonparametric methods

Sleep-wake rhythm disturbances in patients with Alzheimer’s disease (AD) make a strong demand on caregivers and are among the most important reasons for institutionalization. Several previous studies reported that the disturbances improve with increased environmental light, which, through the retinohypothalamic tract, activates the suprachiasmatic nucleus (SCN), the biological clock of the brain. The data of […]

Transcutaneous electrical nerve stimulation (TENS) improves the rest–activity rhythm in midstage Alzheimer’s disease

Nightly restlessness in patients with Alzheimer’s disease (AD) is probably due to a disorder of circadian rhythms. Transcutaneous electrical nerve stimulation (TENS) was previously reported to increase the strength of coupling of the circadian rest–activity rhythm to Zeitgebers in early stage Alzheimer’s disease (AD) patients. It was investigated in the present study whether TENS could […]

Indirect bright light improves circadian rest-activity rhythm disturbances in demented patients

Light is known to be an important modulator of circadian rhythms. We tested the hypothesis that an enduring increase in the daytime environmental illumination level improves restactivity rhythm disturbances in demented patients. Actigraphy was performed before, during, and after 4 weeks of increased illumination in the living rooms of 22 patients with dementia clinically diagnosed […]

Long-term fitness training improves the circadian rest-activity rhythm in healthy elderly males

In old age, the circadian timing system loses optimal functioning. This process is even accelerated in Alzheimer’s disease. Because pharmacological treatment of day-night rhythm disturbances usually is not very effective and may have considerable side effects, nonpharmacological treatments deserve attention. Bright light therapy has been shown to be effective. It is known from animal studies […]

Circadian rest—activity rhythm disturbances in alzheimer’s disease

Previous studies showed circadian rhythm disturbances in patients with Alzheimer’s disease. Rest-activity rhythm disturbances manifest themselves through a fragmentation of the rhythm, a weak coupling with Zeitgebers, and high levels of activity during the night. The aim of the present study was to investigate which factors contribute to the presence of these disturbances. Therefore, several […]
