Dementia Definition

Dementia is a group of conditions that cause memory loss, impaired thinking, and difficulty performing daily tasks, most commonly affecting older adults.

Dementia Meaning

Dementia is an umbrella term for a range of conditions that impair memory, reasoning, language, and other cognitive functions. It is not a normal part of aging, though age is a major risk factor. The most common type of dementia is Alzheimer’s disease, but others include vascular dementia and Lewy body dementia.Dementia affects each person differently, but symptoms generally worsen over time. It can make it difficult for a person to complete daily tasks, recognize loved ones, or communicate clearly. While there is currently no cure, early diagnosis, cognitive therapies, medication, and environmental support can improve quality of life and slow progression. Support for caregivers is also essential as the disease progresses.
