My father has Parkinson’s. Can we begin Carbidopa-Levodopa?

Question

Hello doctor,

My father, aged 66, was recently diagnosed with early-stage Parkinson’s after he developed a resting tremor and stiffness in his left arm. His DaTscan confirmed dopaminergic deficit. He is still independent, but movement is slowing down. We are worried about how fast this condition may progress and what signs to watch for that signal worsening.

The doctor mentioned Carbidopa-Levodopa, but said it might be too early.
Could physical therapy slow down symptoms?
Also, are there any diet changes or supplements known to be beneficial in Parkinson’s management?

Kindly suggest.

Hello,

Welcome to icliniq.com.

I understand your concern.

Your father's diagnosis of early-stage Parkinson’s disease, especially with symptoms like resting tremor and stiffness in one limb and a confirmed dopaminergic deficit on DaTscan (dopamine transporter scan), suggests he is in the initial phase of the condition, where symptoms can still be well managed and progression is often gradual.

While the rate of progression varies between individuals, early signs of worsening can include

Increased slowness of movement.
The tremor spreads to the other side of the body.
Balance issues.
Subtle changes in facial expression, handwriting, or speech.

Starting Carbidopa-Levodopa early is a nuanced decision and depends on how much the symptoms are interfering with daily life. Many doctors hold off if symptoms are mild, since long-term use can lead to motor fluctuations or dyskinesias, although the benefits can outweigh risks if symptoms progress.

You should also make some lifestyle modifications, such as

Physical therapy, especially targeted exercise programs focusing on balance, gait, and flexibility, has strong evidence in slowing motor decline and improving quality of life.
Regular aerobic exercise, such as walking, cycling, or swimming, is also beneficial.
Regarding diet, a Mediterranean-style diet rich in antioxidants and fiber may support brain health and digestive function, which is often affected in Parkinson’s.
Some patients benefit from avoiding protein-heavy meals near medication times, as protein can interfere with Levodopa absorption.
While there is no cure, certain supplements like CoQ10 (coenzyme Q10) and vitamin D have been studied, but their effectiveness remains uncertain.

I hope this helps. Feel free to reach out at any time. I am always here to help.
