Brain Atrophy

Brain regeneration after atrophy is possible through specific, actionable interventions. The aging brain shrinks at approximately 0.4% per year, accumulating into broad cognitive deficiencies over time. In Alzheimer's and Parkinson's disease, neurons cannot absorb glucose effectively, causing them to starve and disconnect, breaking down neural communication networks. Reduced brain volume causes two simultaneous problems: decreased circulation to neurons and loss of the neurons' ability to absorb glucose. Both smoking and alcohol directly impair brain physiology through neurotoxicity, B vitamin depletion, and reduced cerebral circulation.
