3?��?5.7 vs 15.4?��?5.8, P? http://www.selleckchem.com/products/r428.html or intrinsic visceral stimuli in the elderly. We review data on changes in autonomic nervous http://www.selleck.cn/products/3-methyladenine.html system regulation of cardiovascular and urinary function, as well as data on strategies to improve function. There are data showing alterations in peripheral and central autonomic nerve activity, and decreases in neurotransmitter receptor action that lead to diminished autonomic reactivity (e.g. blood pressure and cerebral blood flow regulation) and poorly coordinated autonomic discharge (e.g. bladder function). Simple strategies for autonomic function improvement and increasing cortical blood flow include walking and somatic afferent stimulation (e.g. stroking skin or acupuncture) to increase sympathetic, parasympathetic and central cholinergic activity. Geriatr Gerontol Int 2010; 10 (Suppl. 1): S127�CS136. The autonomic nervous system is essential for fast adaptation or modulation of visceral functions during changes in external and internal environments. In elderly people, autonomic functions are relatively well maintained at rest, but patients' ability to adapt to environmental or visceral changes are often seriously impaired. Some impairments, such as blood pressure regulation, can put patients at considerable risk of injury or present challenging obstacles for unassisted living. Other impairments, for example bladder control, can be accommodated with relatively minor behavioral adjustments, but these can produce strong feelings of loss of control http://www.selleckchem.com/products/PF-2341066.html for patients. The incidence of many diseases increases with age and chronic diseases are often accompanied by autonomic nervous system dysfunction. These causes of autonomic nervous system function will not be reviewed. Here, we will review the recent knowledge on changes in autonomic nervous regulatory functions during normal aging and their mechanisms, especially on regulation of the cardiovascular and urinary functions. The incidence of cardiovascular disease, such as heart disease and cerebrovascular disease increases, occupies the highest ratio of cause of death in the elderly. Generally, resting blood pressure rises almost in parallel with age.
