Which of the following is part of the exercise recommendations for Lewy body dementia?

• A. Frequency: 5 to 7 days; Intensity: vigorous; Time: 60 min; Type: running.
• B. Frequency: 1 day; Intensity: rest; Time: 5 min; Type: none.
• C. Frequency: 3 to 5 days; Intensity: light to moderate; Time: 20 to 40 min; Type: supervised balance and mobility training.
• D. Frequency: 2 days; Intensity: moderate; Time: 25 to 55 min; Type: cycling.

Answer: (C)

Regular, moderate exercise with a focus on balance helps Lewy body dementia patients maintain mobility, reduce fall risk, and manage fatigue and attention fluctuations. The best option fits this approach: it recommends exercising three to five days per week, at light to moderate intensity, for 20 to 40 minutes per session, and it specifies supervised balance and mobility training. This combination provides consistent activity that is safe for motor and cognitive symptoms, targets balance deficits, and uses supervision to reduce the risk of falls.

Other options don’t fit as well because they either push too hard (vigorous intensity or high-impact activity like running), are too infrequent to maintain benefits (only one day per week), or lack a structured, balance-focused component (no specified type or supervision).
