Which dementia is known to affect 1 in 10 people aged 65 and older, and is the 5th leading cause of death for this age group?

Alzheimer's dementia is a progressive neurodegenerative disease that primarily affects older adults, with approximately 1 in 10 individuals aged 65 and older affected by this condition. It is characterized by the gradual decline in cognitive functioning, impacting memory, reasoning, language, and ultimately leading to difficulties in daily living.

The prevalence of Alzheimer's dementia is significant in the older adult population, making it a major public health concern. It is also recognized as the fifth leading cause of death among this age group. This prominence is attributed to the combination of its widespread occurrence, the complexity of its symptoms, and its severe impact on overall health, often leading to complications such as infections or other health issues that can result in mortality.

Understanding these points highlights the critical importance of Alzheimer's dementia in geriatric mental health, and emphasizes the need for early diagnosis, intervention strategies, and support systems for patients and their families.
