[Campbell Biology P.1153] Which statement accurately differentiates Alzheimer's disease AD fr... | Practice Question

Which statement accurately differentiates Alzheimer's disease AD from Parkinson's disease PD based on the provided text?

  • A: AD primarily affects motor control due to dopamine neuron death, while PD leads to widespread cognitive decline.
  • B: AD is characterized by beta-amyloid plaques and tau tangles, whereas PD involves the death of dopamine-releasing neurons in the midbrain.
  • C: Both AD and PD are primarily treated by L-dopa administration.
  • D: Protein aggregates are found only in AD, not in PD.

Explanation

The text clearly states that Alzheimer's is characterized by beta-amyloid plaques and neurofibrillary tangles, while Parkinson's disease involves the death of dopamine-releasing neurons in the midbrain.
