Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Hypothesis: There exists patients who have met ALS or PMA diagnostic criteria and subsequently experienced robust and sustained improvement, i.e. a "reversal." Thirty-eight of these patients were identified in the prior Duke University study, Documentation of Known ALS Reversals (St.A.R. Protocol 1, Duke IRB Pro00076395). The investigators hypothesize these patients have had different environmental exposures than patients with typically progressive ALS. Identification of specific environmental influences may point to exposures which are protective or exposure that lead to the development of a rare and novel reversible ALS-like disease. Objective: This study seeks to identify environmental exposures associated with ALS reversals.
