can exercise really be good for your brain?
Aug 20, 2013

nelson, what do you think of the recent study saying exercise can reduce neurocognitive impairment by half?

Response from Mr. Vergel

I think it makes perfect sense. Blood flow to the brain has been shown to be impaired in HIV+ people. Exercise may help increase blood flow.

Resting cerebral blood flow A potential biomarker of the effects of HIV in the brain

"In a 3-month study of 16 women age 60 and older, brisk walking for 30-50 minutes three or four times per week improved blood flow through to the brain as much as 15%"

Moderate Exercise Dramatically Improves Brain Blood Flow in Elderly Women

"Regardless of age, cognitive (executive) function is improved while exercising"

Effect of age on exercise-induced alterations in cognitive executive function: relationship to cerebral perfusion.

So, exercise not only improves body composition, lipids, blood pressure, glucose control, but can also slow down the effects of aging on the brain. What pill can have all those benefits?!
