Question

Quizplus · Accepted Answer

Alzheimer's disease is a progressive brain disorder that impairs memory, thinking, and behavior. It is the most common cause of dementia, accounting for around 60-80% of cases. The first symptoms are often related to memory loss, but as the disease progresses, it affects other cognitive functions as well. Distant memories are typically affected later in the disease process.

Therefore, option B is the true statement as it correctly states that recent memory impairment is followed by impairment in recall of distant events.
