What is the on/off phenomenon?

The “on-offphenomenon in Parkinson's disease (PD) refers to a switch between mobility and immobility in levodopa-treated patients, which occurs as an end-of-dose or “wearing off” worsening of motor function or, much less commonly, as sudden and unpredictable motor fluctuations.

Moreover, what can cause the on/off syndrome?

This common problem in Parkinson's disease requires a thoughtful approach. Levodopa is the "gold standard" medication for Parkinson's disease, which means it's the most beneficial and primary drug. This is because, over time, levodopa starts to wear off more and more quickly, triggering a medication "on-off phenomenon.

Also Know, why do Parkinson's drugs stop 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.

Correspondingly, what happens if you don't treat Parkinson's?

Many patients eventually have trouble walking, driving, and performing simple daily tasks. Parkinson's disease is a chronic, progressive condition, and, if left untreated, the symptoms will grow steadily worse. Some viruses, such as a certain strain of influenza A, may also be responsible for bringing on Parkinson's.

What happens when Levodopa stops working?

Some patients notice the return of motor symptoms during "off" time – that's why the phenomenon can also be referred to as "motor fluctuations." You may also notice a drop in energy levels, or an increase in muscle stiffness, depending on your individual Parkinson's symptoms.
