Answer to Question 1

Answer: Huntington's disease (HD) is caused by degeneration of the caudate nucleus and the putamen. The disease is marked by uncontrollable jerky movements of the arms and legs. HD is a hereditary disorder, related to a dominant gene on chromosome 4. Parkinson's disease is associated with neurodegeneration of the nigrostrial dopamine system and involves tremor at rest, muscle rigidity, slowness of movement, and postural instability.

Answer to Question 2

Answer: Stroke can involve obstructions of brain blood vessels or can involve the rupture of blood vessels. Known risk factors include cigarette smoking, high blood pressure, high blood cholesterol levels, diabetes, and the presence of plaque within the lumen of blood vessels (atherosclerosis).
