Answer to Question 1

ANS: B
Agnosia is the failure to identify objects despite intact sensory function. Apraxia is the ina-bility to carry out purposeful, complex movements and use objects properly. Aphasia refers to inability to speak (expressive) or inability to comprehend what is said or written (receptive). Amnesia is inability to remember a significant block of information.

Answer to Question 2

ANS: C
The prevailing theories of etiology of Alzheimer's disease include the following: angiopathy and blood-brain barrier incompetence; neurotransmitter and receptor deficiencies of acetyl-choline; abnormal proteins, specifically -amyloid and their products; and genetic defects. Neither serotonin nor prions are implicated as problems in Alzheimer's disease.
