Link between sleep, cognitive impairment in the elderly

Daytime sleepiness is very common in the elderly with prevalence rates of up to 50 percent. Caused by sleep-disordered breathing (SDB), a disruption of normal breathing during sleep, these cause recurrent awakenings and subsequent excessive daytime sleepiness. Now a researcher stresses that it is time for physicians to consider the association between these sleep conditions and cognitive impairment in the elderly. Source

Sleep apnea immediately compromises blood pressure

A single bout of sleep apnea impacts the human body’s ability to regulate blood pressure, say researchers. Sleep apnea is a condition where breathing repeatedly stops and starts during sleep. The condition can result in frequent periods of decreased oxygen levels in the body, known as intermittent hypoxia. Source

Alcoholism worsens insomnia, but there is hope

Individuals with alcohol dependence (AD) often have sleep-related disorders such as insomnia, circadian-rhythm sleep disorders, breathing-related sleep disorders, movement disorders, and parasomnias such as sleep-related eating disorder, sleepwalking, nightmares, sleep paralysis, and REM sleep behavior disorder. A new review examines the various aspects of insomnia associated with AD. Source

‘Gestational sleep apnea’: Wake up to a new diagnosis

Approximately one quarter of pregnant women may suffer from Obstructive Sleep Apnea (OSA), the recurrent cessation or limitation of normal breathing during sleep, new research suggests. In addition to being the cause of daytime fatigue, the consequences of untreated OSA include but are not limited to high blood pressure, high blood sugar, and heart disease. Source
