Why Is MAOA Important?
Because of its role in breaking down so many different types of neurotransmitters and other compounds, the MAOA gene is one of the most highly-studied genes out there.
As a result, scientists have identified many significant variants that different people can carry in the MAOA gene. These variants, in turn, may increase or decrease the production of the MAOA enzyme, or modify its structure — all of which can have major effects on a person’s overall level of MAOA activity.
Thank you very much Kia for highlighting this important point.
Thank you Michel.
If some supplements or medications work for someone but don’t work for another person with PD, the culprit is this enzyme (MAOA) and of course MAOB and COMT enzymes.To name few of them : Vitamin B2 - B1- B6 - B12 - B9- Tryptophan, Thyrosin, Lithium ortate, celery seeds extract, Berberine, curcumin and many others.
In my experience if you know how these enzyme act in your system, you can control most of your motor and non-motor symptoms. I have done and it works well.
You will not be able control the PD without knowing how to deal with these 3 enzymes.
It may take few days for someone to findout abou activity of these enzymes in his/her body and for another months or even year but IT’S WORTH IT,
Why can mice be cured of PD? 
Sudden change of health
Continuous activation of NRF2 can be pro-tumourigenic
Why some of very active members are absent for quite some time
