Naltrexone is a medication approved by the United States Food and Drug Administration for treating drug and alcohol addiction. In very low doses, it has been found amazingly helpful in the treatment of Parkinson's disease--with minimal side effects and at a price anyone can afford.
This site explains what Low Dose Naltrexone (LDN) is and how it works:
Unfortunately, like dopamine agonists, it appears LDN is only a temporary fix for Parkinson's disease, as the following message to me from Mary Bradley, the author of Up The Creek With A Paddle, suggests:
Nothing pleases me more than LDN helping people with PD.
As you know, we are all on the same side. I wish LDN worked for everything! My uncle [who has PD] definitely got some good years out of it. He has taken nothing but LDN until now. We need to look elsewhere now because he can no longer sit still, read, or write. He has definitely progressed as have all of Dr. Bihari's other original PD patients.
I spoke in depth with Dr. Bihari about this. We don't know why, but LDN just doesn't seem to work as well for PD as it does for MS. Maybe PD is not autoimmune, or maybe the age of PD patients is a factor. I mean, they are older than the MS crew and aging is going to get the best of all of us one day. Or maybe it was just LDN failed those 9 patients with PD. I don't know. I do know I must always report what I see.
The bottom line is, we need research to see what is really going on so that we keep everyone's expectations as realistic as possible. Keep in mind, LDN didn't work for my mother with breast cancer, but worked for many others. But again, the success rate of LDN with cancer is not as high as it is with MS.
In my opinion, LDN shows great potential in the treatment of Parkinson's disease, even if only on a temporarty basis, and merits most careful consideration.
In addition to PD, LDN has also been found effective in treating the diseases and conditions listed here:
