Dementia isn’t a single disease. It’s a broad term used to describe a group of conditions that affect memory, thinking, and the ability to carry out everyday tasks. While it’s more common as people age, it’s not a normal part of aging.
According to the World Health Organization, dementia is one of the leading causes of disability and dependency among older adults worldwide. Millions of people are affected each year—and because symptoms develop gradually, they’re often overlooked in the early stages.
