Non-drug methods could help Alzheimer’s disease. Around twenty-five percent of the world’s population is born with one copy of the Alzheimer’s gene, and two to three percent is born with two copies, giving them double the risk of developing the disease. A healthy diet, regular exercise, and a strong social life have already been proven to slow the development of the disease, but researchers in Finland recently set out to compare the effects of these variables specifically on people with and without the Alzheimer’s gene. The participant, none with signs of current cognitive impairment, were randomly assigned to a fairly intense diet, exercise, and brain training program. Those assigned to this intense program all performed similarly well on memory and cognition tests, regardless of whether or not they possessed the predisposition gene for Alzheimer’s, suggesting that those lifestyle changes are equally helpful for all people. More studies will have to be done to determine whether these non-drug therapies are more effective on people with the gene.
