Exercise Motivates Brain Function in Alzheimer’s Patients


Scientists from the University Of Maryland School Of Public Health conducted the research, which unveils that exercise can enhance cognitive functionality in individuals at the threat of Alzheimer’s by enhancing the performance of brain activity.


The research examined 17 individuals with mild cognitive impairment (MCI) – early memory loss related with Alzheimer’s disease – alongside 18 controls. Both categories were of similar age, gender, education, genetic risk and had identical drug usage. The subjects were requested to perform a 12-week exercise program, which composed of walking on a treadmill, at modest intensity while getting monitored by a personalized instructor. Every day after and before the exercise program, both categories were requested to complete memory exams.


The 1st was fMRI famous name for discrimination task. This is a memory task that examines the individuals to recognize popular names as their mind functionality was assessed. The second was a list learning task. This test engaged the individuals remembering words, read to them from a list over 5 successive attempts, and again after being diverted with a various list.

Outcomes of the research revealed that both categories enhanced their fitness levels by about 10%. But the fMRI examined the following that an exercise program showed a considerable improves in the intensity of brain activation in 11 brain areas as the individuals properly recognized popular names. The areas of the brain triggered with enhanced efficiency were the same areas of the brain that shows the diagnosis of Alzheimer’s disease. The areas involved were the precuneus region – the area engaged in episodic memory, the temporal lobe and the parahippocampal gyrus – an area that performs a role in memory encoding and recovery.

The scientists say that what makes these outcomes even more exciting is that these outcomes were obtained using the levels of exercise that are in line with physical work suggestions for older adults. The suggestions motivate moderate intensity exercise over most days, totaling 150 minutes each week, the scientists add. The research authors say that this study indicates that exercise could restrict the need for over-activation in the brain in order to recollect memory. They add that this is motivating for those who want to keep brain function.
