Exercise linked to Lower Alzheimer’s risk, Even in Later Life
CLEVELAND, OH - New evidence reinforces the powerful connection between physical activity and brain health, suggesting exercise can significantly reduce the risk of developing Alzheimer’s disease and perhaps slow cognitive decline in those already affected. Reports indicate over 55 million people worldwide are currently living with Alzheimer’s, a condition for which there is currently no cure.
However, proactive steps can be taken to mitigate risk. According to Dylan Wint, MD, a neurologist at Cleveland Clinic, “Exercise does seem to reduce the risk of developing Alzheimer’s disease, and also other dementias or other causes of cognitive decline. There’s fairly strong and consistent evidence showing that those who exercise regularly are less likely to develop cognitive decline.” He further explains that regular exercise can also slow the progression of cognitive decline and the associated loss of abilities in individuals already experiencing mild impairment.
Research suggests exercise may boost levels of key brain chemicals and neurotransmitters vital for preserving brain health, and also offers vascular benefits.
Dr. Wint recommends at least 150 minutes of moderate-intensity aerobic activity each week. Acceptable activities include brisk walking, jogging, swimming, cycling, and even active household chores. This exercise doesn’t need to be completed in one session; options include 30 minutes daily or 75 minutes twice a week.
“While starting earlier is likely to be better, it’s never too late to start,” Dr. Wint emphasized. “Even older individuals who have never done a minute of exercise in their lives can benefit in terms of risk reduction by engaging in exercise even at an advanced age.” He also noted the broader benefits of exercise, stating it “helps to stave off or reduce symptoms of depression and anxiety as well.”
Alongside exercise,Dr. Wint highlights the importance of diet, citing studies that show the Mediterranean diet and the MIND diet are notably effective in preventing cognitive decline.
