Daytime sleepiness is very common in the elderly with prevalence rates of up to 50 percent. Caused by sleep-disordered breathing, a disruption of normal breathing during sleep, these cause recurrent awakenings and subsequent excessive daytime sleepiness.

One of the earliest signs of Alzheimer’s disease is a decline in glucose levels in the brain. It appears in the early stages of mild cognitive impairment—before symptoms of memory problems begin to surface.
