Question

Quizplus · Accepted Answer

Parkinson's disease primarily affects the basal ganglia, which are involved in procedural memories, such as motor skills, rather than declarative memories, such as facts and events. Therefore, it is likely that Samantha's grandfather will experience problems with procedural memories but not declarative memories. Memory impairment is not a hallmark symptom of Parkinson's disease, so choice A is incorrect. Similarly, choice C and D are also incorrect because Parkinson's disease primarily affects procedural memories, not declarative memories.
