Final answer:
The treatment for Parkinson's disease involves medication to ease symptoms. L-DOPA is a commonly prescribed drug that increases dopamine levels in the brain. Other drugs can inhibit the breakdown of dopamine.
Step-by-step explanation:
There is no cure for Parkinson's disease, and treatment is focused on easing symptoms. One of the most commonly prescribed drugs for Parkinson's is L-DOPA, which is a chemical that is converted into dopamine by neurons in the brain. This conversion increases the overall level of dopamine neurotransmission and can help compensate for the loss of dopaminergic neurons in the substantia nigra. Other drugs work by inhibiting the enzyme that breaks down dopamine.
