Answer and Explanation

The Correct Answer is A

A. Manifests as neurofibrillary tangles and amyloid plaques that cause a disruption of brain impulses: Alzheimer's disease is characterized by the accumulation of amyloid plaques and neurofibrillary tangles in the brain, leading to disrupted neural communication.

B. Is an inherited disorder that, most often, begins before the age of fifty: While there are inherited forms of Alzheimer's (early-onset), most cases are sporadic and occur after age 65.

C. Can be caused by increased cerebral levels of acetylcholine: Alzheimer's disease is associated with decreased levels of acetylcholine, not increased levels.

D. Causes unusual sensory sensations such as numbness and shooting pain (paresthesia): Paresthesia is not a typical symptom of Alzheimer's disease; it is more related to neurological or peripheral nerve disorders.
