Nighttime Agitation in Persons with Dementia as a Manifestation of Restless Legs Syndrome.

Objectives: Nighttime agitation or "sundowning" is challenging for clinicians and caregivers to manage in older adults in the dementia stage of Alzheimer's disease (AD-D). Our research previously revealed that nighttime agitation might be a manifestation of restless legs syndrome (RLS). The current study aims to describe the characteristics of older adults with AD-D, nighttime agitation, and RLS, and to evaluate sleep disturbance and iron status in relation to nighttime agitation severity.

Nighttime Agitation and Restless Legs Syndrome in Persons With Alzheimer's Disease: Study Protocol for a Double-Blind, Placebo-Controlled, Randomized Trial (NightRest).

Unlabelled: Nighttime agitation is a prevalent symptom in persons with Alzheimer's disease (AD). Effective treatments are absent due to our limited knowledge of its etiology. We hypothesized that restless legs syndrome (RLS), a common neurological sensorimotor disorder of uncomfortable leg sensations that appear at night and interfere with sleep, might be a cause for nighttime agitation in persons with AD.
