The number of people diagnosed with dementia in the United States is projected to double to 1 million annually by 2060, according to a JAMA study. Globally, new cases are expected to more than double from 11.4 million in 2023 to 24.7 million by 2050. This rise, driven by increased life expectancy and demographic shifts, will strain an already challenged healthcare system, particularly in long-term care and geriatric medicine. Experts emphasize the need for dementia prevention, drug development, and addressing critical labor shortages in caregiving roles.
