The LDN for PLS & HSP Group is for persons who have PLS, HSP, ALS, SP, or anyone who may not yet be diagnosed but who is showing signs/symptoms of upper motor neuron damage; AND who are taking low dose naltrexone (LDN) or are considering taking LDN. This group also accepts relatives and caregivers of the above, or anyone else interested in the results of LDN on the progression of our diseases.

Members who are using LDN will be expected to provide periodic updates (at least once, preferably twice a year) about their experiences with LDN.

Together we can determine the effectiveness of LDN's ability to slow or stop our diseases.
