People and families suffering from Alzheimer’s and dementia often feel desperate for a cure and will try anything. Unfortunately, no cure exists and not a single treatment has been shown to reverse the effects of these brain diseases once they’ve started. Millions of Americans are afflicted by Alzheimer’s and dementia, and dishearteningly, the numbers are growing. But studies show that prevention via simple lifestyle habits is extremely effective, and some simple changes in diet, exercise and sleep practices can reduce the chances of developing brain disease by up to 40 or 50 percent. Drs. Ayesha and Dean Sherzai are a husband-and-wife team of neurologists who co-direct the Alzheimer’s Prevention Program at Loma Linda University in Southern California. In this talk from the 2023 Aspen Ideas Festival, the Sherzais share some of the most hopeful and accessible tips on adopting a healthy lifestyle that can optimize long-term brain health and keep cognitive decline at bay.
