There have been many trials and studies carried out on Low Dose Naltrexone. Below you will find a list of published papers. This list of clinical trials has been repurposed from, and was originally compiled by, LDN Research Trust.
At the bottom of this page are several anecdotal surveys, including two which were conducted by LDNers.org.

8. Research on Neurodegeneration at NIEHS Suggests a Protective Naltrexone Role J.S. Hong, Ph.D., head of the Neuropharmacology Section of the Laboratory of Pharmacology and Chemistry at the National Institute of Environmental Health Sciences, finds that “morphinan” drugs, including naltrexone and naloxone, are able to reduce inflammatory reactions in microglia brain cells in animal studies. Such inflammation is believed to be central to the progressive neurodegenerative effects seen in disorders such as Parkinson’s disease and Alzheimer’s disease. Hong’s report, summarizing the role of microglia in inflammation-related neurodegeneration and the potential of therapy using morphinans, appears in a January 2007 issue of Nature Reviews Neuroscience [8(1):57-69].

This survey tracks the change in disability before and after LDN for 157 respondents to the survey.
LDN Research Trust Survey (Ongoing)
If you are a current or past user of Low Dose Naltrexone, consider participating in this ongoing survey. All the anecdotal evidence will be collated and presented in a statistical format to help gain funding and support from the medical profession. Eminent Neurologist Dr Alasdair Coles, from Addenbrookes hospital in Cambridge has given his approval and consent to this survey. Complete the online survey form, click “send” and it will go directly to the LDN Research Trust. The LDN Research Trust will not pass your details on to a third party for any purpose whatsoever.
