De­lay Alzheimer’s by ex­er­cis­ing reg­u­larly

The Sunday Guardian - - LIVING - COR­RE­SPON­DENT

Phys­i­cal ex­er­cise can help counter the loss of mem­ory caused by Alzheimer’s as well as de­lay the on­set of the most com­mon type of de­men­tia, ac­cord­ing to a study.

Re­searchers at the Fed­eral Uni­ver­sity of Rio de Janeiro (UFRJ), es­tab­lished a link be­tween levels of irisin, a hor­mone pro­duced by the body dur­ing ex­er­cise, and the de­vel­op­ment of the pro­gres­sive dis­ease, Xin­hua news agency re­ported.

The tests, car­ried out on rats with Alzheimer’s, showed low levels of irisin in the brains of Alzheimer’s suf­fer­ers, and a re­ver­sal in mem­ory loss when irisin levels were boosted through phys­i­cal ex­er­cise.the study showed that “the levels of this hor­mone are in fact de­creased in the brains of pa­tients with Alzheimer’s”, said Ser­gio Fer­reira, Pro­fes­sor at the UFRJ.

In ad­di­tion, the team showed that by boost­ing the levels of the hor­mone, “mem­ory im­proves”.by show­ing that “irisin is an im­por­tant me­di­a­tor of the ben­e­fi­cial ef­fects of ex­er­cise,” the find­ings in­di­cate the hor­mone can be “a novel agent ca­pa­ble of op­pos­ing synapse fail­ure and mem­ory im­pair­ment”, said the study pub­lished in the jour­nal Na­ture Medicine. The re­search also re­in­forces the im­por­tance of phys­i­cal ac­tiv­ity in prevent­ing mem­ory loss and brain dis­eases, in­clud­ing Alzheimer’s, the re­port said. Alzheimer’s is a de­gen­er­a­tive dis­ease that erodes mem­ory, even­tu­ally im­pair­ing lan­guage, rea­son­ing and other men­tal func­tions. IANS
