Final answer:
The primary treatment for early stages of Parkinson's disease is medication, with L-DOPA being the most common drug used to increase dopamine levels in the brain.
Step-by-step explanation:
The main treatment for Parkinson's in the earlier stages is medication. Specifically, L-DOPA is one of the most commonly prescribed medications for this condition. L-DOPA works by converting into dopamine in the brain, thus compensating for the loss of dopaminergic neurons in the substantia nigra, which are responsible for producing dopamine. Additionally, other drugs may be prescribed to inhibit the enzyme that breaks down dopamine, helping to maintain dopamine levels.
