What is the recommended management for a known dementia patient who becomes tachycardic and agitated?

• A. Encourage a normal sleep-wake cycle
• B. Increase physical activity with late-night workouts
• C. Administer sedatives to calm them immediately
• D. Ignore tachycardia

Answer: (A)

Maintaining a regular sleep-wake pattern is most effective because dementia-related agitation and tachycardia often stem from disruption of circadian rhythm and delirium. When the environment supports day-time activity and light exposure, and preserves a calm, dark, quiet night, autonomic arousal decreases and confusion or agitation improves. This nonpharmacologic approach helps stabilize heart rate by reducing sympathetic surge that accompanies nocturnal wakefulness and agitation. Administering sedatives right away can oversedate, mask underlying problems, and may worsen delirium; increasing late-night activity would further disrupt sleep and worsen tachycardia; ignoring the tachycardia risks missing a treatable issue. So, the best initial management is to promote a normal sleep-wake cycle.
