Effect of Lithium Carbonate in Patients With Amyotrophic Lateral Sclerosis

Open Multicenter Study of Lithium in Patients With Amyotrophic Lateral Sclerosis LISLA

The purpose of the study is to determine whether lithium is safe and effective in the treatment of ALS

Daily doses of lithium, have been found to delay progression of amyotrophic lateral sclerosis (ALS) in a 15-month study of 44 patients with ALS. At the end of the trial, about 30 percent of the patients that took riluzole had died, while all those receiving riluzole plus lithium had survived. the lithium group had slower progression as measure by a test of breathing (FVC) and strength.

This study will determine whether lithium in combination with riluzole delay progression of patients with amyotrophic lateral sclerosis disease in comparison of an historical cohort of ALS patients treated with riluzole alone.

Exclusion Criteria:
