Which statement about dementia is NOT true?

The statement that 50% of the older adult population suffers from some form of dementia is not true. Current research and statistics indicate that while dementia prevalence increases with age, the percentage of older adults affected is significantly lower than 50%. For instance, studies show that only about 5-10% of individuals aged 65 and older have dementia, and this percentage rises dramatically with age, but it does not reach half of the population.

Understanding dementia involves recognizing its varied forms, such as Alzheimer's disease and vascular dementia, as well as its incidence and prevalence within specific age groups. The distinctions between different types of dementia highlight the complexity of the disease and the importance of accurate statistics to avoid misconceptions about its widespread impact among older adults.
