Many neurological diseases are also directly related to aging.
Thousands of published studies have been evaluated substantiating that a decline of cognitive function can be controlled. Some of these studies demonstrate that prevention will help maintain optimal brain function, while others show measurable benefit in reversing cognitive impairment caused by normal aging or by a specific disease of aging, such as stroke. Models of Cognitive Impairment Age-associated neurological impairment may manifest itself in a variety of forms, including memory loss , senility, alzheimer's disease and dementia. Dementia includes those diseases involving nerve cell deterioration and is defined as a loss in at least two areas of complex behavior. Impairment must be severe enough to interfere with a person's normal, daily ability to function.
