During the moderate stage of Alzheimer's disease, which features are commonly observed?

• A. Forgetting life events, difficulty with tasks, changes in sleep patterns, personality changes, wandering
• B. Rapid spontaneous memory recovery
• C. Complete recovery of previous abilities
• D. No cognitive changes

Answer: (D)

In the moderate stage of Alzheimer's disease, cognitive decline is progressive and spills into daily life. You’d expect memory loss that affects personal history and recent events, plus trouble with instrumental activities of daily living like managing finances, preparing meals, or keeping track of appointments. Sleep patterns often become disrupted, and personality or behavior can change—agitation, withdrawal, or suspiciousness are common. Wandering or getting lost due to confusion is also a frequent safety concern. This combination reflects broader impairment beyond memory, including orientation, judgment, language, and behavior, which is characteristic of the shift from mild to moderate disease and signals the need for increased supervision and support. Rapid spontaneous memory recovery, complete recovery of prior abilities, or no cognitive changes do not align with this stage of progression.
