SOLID EV­I­DENCE THAT PHYS­I­CAL AC­TIV­ITY IS PRO­TEC­TIVE

Health & Nutrition - - SENIOR CARE -

Two large stud­ies found that low lev­els of phys­i­cal ac­tiv­ity may af­fect brain vol­ume and de­men­tia risk. Ac­cord­ing to the stud­ies, phys­i­cal ac­tiv­ity par­tic­u­larly af­fected the size of the hip­pocam­pus, a re­gion of the brain that con­trols short-term mem­ory. The in­fer­ence is that reg­u­lar ex­er­cise could help se­niors main­tain or in­crease their brain vol­ume, and re­duce the risk for de­men­tia. Doc­tor’s verdict Phys­i­cal ac­tiv­ity re­duces the risk for high blood pres­sure and choles­terol, and stroke, which are as­so­ci­ated with greater risk for Alzheimer’s. If I could give only one piece of ad­vice to mid­dle-aged and el­derly peo­ple with or with­out mem­ory trou­ble, it would be to get 30 min­utes of brisk ex­er­cise at least three times a week, and prefer­ably ev­ery day. Also try to sched­ule strength-train­ing ses­sions at least three times a week.
