Which of the following neurological conditions accounted for the highest percentage of disability-adjusted life years (DALYs) in 2016?

• A. Migraine
• B. Stroke
• C. Dementia
• D. Parkinson disease

Answer: (B)

Stroke accounted for the highest percentage of disability-adjusted life years (DALYs) in 2016 due to its significant impact on both mortality and long-term disability. DALYs combine the years of life lost due to premature death and the years lived with disability, providing a comprehensive measure of a condition's overall burden on population health.

Stroke can lead to severe impairments in mobility, speech, and cognitive functions, resulting in a high rate of long-term disability among survivors. Moreover, its prevalence and the aging population contribute to its substantial impact on health systems globally. While conditions like migraine, dementia, and Parkinson’s disease also affect quality of life and can lead to disability, the acute nature of stroke and its acute onset often result in more significant immediate health consequences, making it a leading cause of DALYs compared to the other neurological conditions listed.
