They may however happen often enough to become so bothersome that medical attention should be sought out. "Parasomnias are disorders characterized by abnormal behavior or physiological events occurring in association with sleep stages, or sleep-wake transitions."(DSM pg. 435) Arousal disorders are the most common type of
Physical Activity and Obstructive Sleep Apnea in Adults Obesity has long been a growing problem in the world and such problem has been related to increases the risks of other diseases and mortality. It has been shown that obesity is also one of the important risk factors for a sleeping disorder, obstructive sleep apnea. Obstructive sleep apnea has been found to have an association with different diseases such as cardiovascular diseases, hypertension, and diabetes. Different ways to undertake this
of heart muscle function, specifically in the left ventricle secondary to coronary artery disease, prolonged hypertension, or myocardial infection (Lewis et al. 2014, 766). The pathophysiology of left-sided heart failure is primary a macroscopic disorder and will be described as such. The loss of heart muscles leads to a decrease in cardiac output, increased preload and increased afterload. Cardiac output (CO) is equal to the stroke volume times the heart rate (CO = SV x HR). When the CO is decreased
