The Strategy Skills Podcast: Management Consulting | Strategy, Operations & Implementation | Critical Thinking

Dr. Majid Fotuhi, neurologist, neuroscientist, and adjunct professor at Johns Hopkins University, has spent decades studying how the brain ages and what determines whether cognitive performance declines or strengthens over time. In this discussion, he challenges one of the most widely accepted assumptions about aging: that deterioration of memory and thinking is inevitable. The evidence, he explains, points in a different direction. Cognitive health is strongly shaped by daily choices, and meaningful improvements can occur within weeks when those choices change.  Fotuhi organizes the science of cognitive resilience around five pillars: exercise, sleep, nutrition, stress management, and brain training. Each pillar affects the brain through measurable biological mechanisms. Exercise, for example, increases mitochondrial activity and stimulates the growth of new neurons in regions responsible for memory. Even modest activity matters. Walking several thousand steps daily has been associated with reduced markers o
