Dementia is an umbrella term for several diseases in which changes in memory, other cognitive abilities, or behavior become severe enough to interfere significantly with activities of daily living. It is therefore a syndrome-level description rather than one single disease .1
Because dementia can arise from different diseases, the pattern of cognitive and behavioral changes is not identical in every person. The term describes the resulting loss of everyday cognitive functioning; identifying the disease responsible for that decline is a separate clinical question .1
Dementia is not a normal part of aging. Age is the strongest known risk factor, but older age alone does not define dementia. The key distinction is that the cognitive or behavioral changes significantly interfere with a person's ability to maintain everyday activities .1
