  • Summary

  • Summary: Dementia represents one of the most significant health challenges facing our aging global population, affecting approximately 55 million people worldwide with projections suggesting this number could reach 139 million by 2050. This comprehensive examination explores dementia's complex nature not as a single disease but as a constellation of symptoms affecting cognitive function through various mechanisms. The analysis reveals how different types of dementia, from Alzheimer's disease to vascular dementia and Lewy body dementia, affect the brain in distinct ways, requiring different approaches to treatment and care. Recent research has revealed both concerning trends and reasons for hope. While population aging drives an overall increase in dementia cases globally, evidence suggests age-specific rates might be declining in some high-income countries, possibly due to better education and cardiovascular health. Prevention strategies have gained increasing attention, with research demonstrating that lifestyle factors including physical exercise, cognitive engagement, social connection, and dietary choices can significantly influence dementia risk.
