Multiple choice

Which of the following is a common feature of many neurodegenerative diseases?

  1. Protein misfolding

  2. Aggregation of misfolded proteins

  3. Loss of neuronal function

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Neurodegenerative diseases are characterized by the misfolding and aggregation of proteins, leading to the loss of neuronal function and eventually cell death.

Multiple choice

Which neurodegenerative disease is characterized by the accumulation of Lewy bodies in neurons?

  1. Alzheimer's disease

  2. Parkinson's disease

  3. Huntington's disease

  4. Multiple sclerosis
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Lewy bodies are a hallmark of Parkinson's disease and contain aggregates of alpha-synuclein protein.
