Why is L-DOPA not working?
In a discovery that might turn out to be a game changer in Parkinson’s research, University of Alabama at Birmingham researchers discovered that DNA methylation causes L-DOPA to stop being effective after a few years, instead giving rise to dyskinesia — involuntary jerky movements making life even harder for patients.
How do you treat on and off phenomenon?
For patients with on-off phenomenon, the goal of therapy is to smooth out the levels of antiparkinsonian medications by giving longer-acting medications, such as dopamine agonists or COMT inhibitors. For particularly brittle patients, liquid Sinemet can be given.
