Background Rest‐activity and sleep‐wake cycles are controlled by the endogenous
circadian rhythm generated by the suprachiasmatic nuclei (SCN) of the hypothalamus …

Circadian dysregulation causes sleep disturbance and impacts quality of life and
functioning. Some interventions target circadian entrainment through modifying light …

Actimetry has been used to estimate the sleep–wake cycle instead of the rest-activity rhythm.
Although algorithms for assessing sleep from actimetry data exist, it is useful to analyze the …

Study Objectives: We investigated the effectiveness of a lighting intervention tailored to
maximally affect the circadian system as a nonpharmacological therapy for treating …

Sleep disturbances are common in persons with Alzheimer's disease or related dementia
(ADRD), resulting in a negative impact on the daytime function of the affected person and on …

Objectives To determine the relationship between quality of life (QOL) and environmental
factors of temperature, noise, and lighting in nursing home residents with severe dementia …

Sleep disturbances are widespread among older adults. Degenerative neurologic disorders
that cause dementia, such as Alzheimer's disease and Parkinson's disease, exacerbate age …

Irregular 24 h light/dark cycles with night‐time light exposure and a low amplitude are
disruptive for sleep, mood and circadian rhythms. Nevertheless such lighting conditions are …

In addition to its role in vision, light exerts strong effects on behavior. Its powerful role in the
modulation of mood is well established, yet remains poorly understood. Much research has …

Dysfunction of circadian and sleep rhythms is an early feature of many neurodegenerative
diseases. Alzheimer's disease (AD) is a progressive neurodegenerative disorder resulting in …
