Explanation:

Parkinson's disease is primarily caused by the degeneration of dopamine - producing neurons in the substantia nigra of the brain. A decrease in interleukin - 6 is not related to triggering Parkinson's. Temporary obstruction of blood vessels is associated with conditions like stroke, not Parkinson's. An increase in acetylcholine receptors is not the cause of Parkinson's; rather, the imbalance between dopamine and acetylcholine due to dopamine neuron loss is a key factor.

Answer:

degeneration of dopamine - producing neurons in the brain
