What is the most common type of dementia affecting older Americans?

Alzheimer's disease is recognized as the most common type of dementia among older Americans, accounting for an estimated 60-80% of dementia cases. This neurodegenerative disorder primarily affects memory and cognitive function, leading to significant impairment of daily living activities and quality of life.

The prevalence of Alzheimer's disease is attributed to several factors, including an aging global population, as the risk for developing the disease increases with age. Research has identified genetic, environmental, and lifestyle factors that contribute to its development and progression.

While the other types of dementia—such as frontotemporal dementia, vascular dementia, and dementia with Lewy bodies—are important and serious, they occur less frequently in comparison to Alzheimer's. Understanding the differences in prevalence, symptoms, and progression of these types of dementia is essential for effective diagnosis and management in therapeutic recreation settings.
