When caught early, lifestyle changes and medical interventions can help slow the onset and manage the effects. In this episode, we explore: What vascular dementia and vascular cognitive impairment are, and how they differ from Alzheimer's disease Why most dementia cases involve both vascular damage and neurodegenerative pathology (mixed dementia) How blood vessel damage begins in childhood and accumulates silently for decades The role of high blood pressure, cholesterol, diabetes, sleep disorders, and chronic stress in damaging brain vasculature Why…
