[Sleep apnea as a risk factor]

Sleep apnea and snoring are widely discussed as risk factors for internal and neurological diseases. The prevalence of snoring in an Austrian population survey is about 27.2% (males 36.5%, females 18.9%), and that of apnea (respectively irregularity and/or cessation of breathing) about 8.5% (31% of all snorers). Clinical symptoms like naps, daytime sleepiness, unquiet sleep, hypertonia, headache in the morning and psychological symptoms may be characteristics of sleep apnea. They should lead to further diagnosis and removal of this risk factor for ischemic heart disease and stroke.
