Alzheimer"s and Exercise...Partners in Recovery?
Alzheimers and exercise go hand in hand in slowing, or even reversing this dreaded disease.
Patients with early Alzheimer's disease who exercised regularly saw less deterioration in areas of the brain that control memory, according to a study released at the 2008 International Conference on Alzheimer's Disease.
Mild Alzheimer's disease patients with higher physical fitness had larger brains compared to mild Alzheimer's patients with lower physical fitness, according to a study published in the July 15, 2008, issue of Neurology®, the medical journal of the American Academy of Neurology.
For the Alzheimers and exercise study, 121 people age 60 and older underwent fitness tests using a treadmill as well as brain scans to measure the white matter, gray matter and total volume of their brains. Of the group, 57 were in the early stages of Alzheimer's disease while the rest of the group did not have dementia.
"People with early Alzheimer's disease who were less physically fit had four times more brain shrinkage when compared to normal older adults than those who were more physically fit, suggesting less brain shrinkage related to the Alzheimer's disease process in those with higher fitness levels," said study author Jeffrey M. Burns, MD, of the University of Kansas School of Medicine in Kansas City and member of the American Academy of Neurology.
The results of this Alzheimers and exercise study remained the same regardless of age, gender, and severity of dementia, physical activity and frailty.
"People with early Alzheimer's disease may be able to preserve their brain function for a longer period of time by exercising regularly and potentially reducing the amount of brain volume lost.
Evidence shows decreasing brain volume is tied to poorer cognitive performance, so preserving more brain volume may translate into better cognitive performance," Burns said.
"This is one of the first studies to explore the relationship between Alzheimers and exercise (cardio respiratory fitness)," said Burns.
The study was supported by the National Institute on Aging, the National Institute of Neurological Disorders and Stroke, the University of Kansas Endowment Association, the Fraternal Order of Eagles and the Oppenheimer Foundation.
