Question

Quizplus · Accepted Answer

Parkinson's disease is caused by the death of dopaminergic neurons in the substantia nigra. The other options are incorrect in their causation. Depression is not caused by death of cholinergic neurons in the basal forebrain, but rather is thought to be related to abnormal functioning of monoamine neurotransmitters such as serotonin and norepinephrine. Huntington's disease is caused by a mutation in the huntingtin gene, leading to the production of an abnormal Huntington protein that damages neurons. Alzheimer's disease is characterized by the aggregation of beta-amyloid protein, which forms plaques in the brain, and tau protein, which forms neurofibrillary tangles. Neither of these proteins kill dopaminergic neurons in the substantia nigra as in Parkinson's disease.
