Which of the following is NOT among the top chronic illnesses reported among the elderly?

Dementia is the correct answer because while it is a significant health concern among the elderly, it does not rank among the top chronic illnesses reported as frequently as the others listed. Chronic illnesses typically include conditions that are long-lasting and require ongoing management, such as heart disease, diabetes, and arthritis.

Heart disease is prominent because of its high prevalence and the serious risks associated with it, including heart attacks and strokes. Diabetes has become increasingly common in the elderly population due to rising obesity rates and lifestyle factors, leading to a variety of complications if not managed properly. Arthritis is also frequently reported among older adults, as joint degeneration and pain significantly impact their quality of life and mobility.

Dementia, while serious, is often classified separately due to its nature as a cognitive disorder. Although it affects a large number of older adults, it is not categorized alongside those chronic physical illnesses that have direct implications for physical health management in the same way.
