What is the most common cause of dementia in the elderly?

• A. Mental health disorders
• B. Being neglected by family members
• C. Exposure to radiation
• D. Alzheimer's disease

Answer: (D)

Alzheimer's disease is the most common cause of dementia in older adults. Dementia refers to a group of progressive cognitive symptoms that arise from various diseases, and Alzheimer's accounts for the largest share of these cases. It is a neurodegenerative condition in which abnormal proteins accumulate in the brain, leading to memory loss, difficulties with language and thinking, and changes in behavior and daily functioning. While other factors and conditions can affect cognition, they are not the primary source of dementia in the elderly. There is no cure, but treatments can help manage symptoms and support safety and daily functioning. As a care provider, recognizing early signs and maintaining routines, safety, and clear communication helps the person cope and stay as functional as possible.
