Question

Quizplus · Accepted Answer

Parkinson's disease is caused by the degeneration of dopamine-producing neurons in the brain. Dopamine is a neurotransmitter that plays a key role in controlling movement and coordination. As the level of dopamine decreases, the symptoms of Parkinson's disease, such as tremors and rigidity, become more pronounced. Cortisol is a stress hormone, serotonin is associated with mood regulation and oxytocin is related to social bonding and attachment.
