Hi,

Parkinson’s disease can be quite debilitating. You can discuss other treatment options available with his treating doctor like COMT inhibitors, Dopamine agonists and MAOB inhibitors. Non pharmacological treatment option like deep brain stimulation, regular physiotherapy and speech therapy will also help.

Thanks
