Dementia Overview
Dementia refers to a range of cognitive disorders affecting memory, thinking skills, behavior, and daily functionality. It's not a specific disease but a syndrome resulting from various underlying conditions or diseases that cause gradual and irreversible brain deterioration. The World Health Organization reported that in 2020, 55 million people were diagnosed with dementia, with a significant majority from low-to-middle-income regions. This number is projected to double in the next two decades.
