Memory loss is often seen as an inevitable part of aging, but neurologist Majid Fotuhi aims to change that perception. In a mindbodygreen podcast, Fotuhi discussed the promising concept that cognitive decline can often be prevented, managed, and even reversed. According to Fotuhi, 45% of dementia cases are linked to modifiable risk factors, a figure he believes is underestimated because it overlooks significant contributors like insomnia and sleep apnea.
Fotuhi identifies a “super problem” with factors such as amyloid plaques, chronic inflammation, and reduced blood flow as causes of brain deterioration. Fortunately, many of these issues are treatable. He cautions against misinterpreting Alzheimer’s biomarkers in blood tests, noting that elevated tau levels can result from various conditions, not solely from Alzheimer’s.
Surprisingly, the hippocampus, responsible for memory, can grow in response to positive behaviors. Regular exercise over 12 weeks can increase its volume by 1 to 3%. Fotuhi’s brain health program, effective for 84% of older adults, emphasizes five pillars: exercise, sleep, nutrition, mindset, and brain training. Exercise is essential, but it should be enjoyable.
Fotuhi finds that lifestyle interventions outperform Alzheimer’s drugs, offering real cognitive improvements. He believes combining lifestyle and medical treatments could revolutionize brain health, reinforcing the idea that our brains adapt to our lifestyles. As he suggests, in stressful moments, we should ask, “Is it worth my hippocampus?”
