Other Information:

Purpose: To examine the clinial efficacy and safety of ultra-high dose (50mg, im, twice a week) methylcobalamin in retarding the progression of symptoms in amyotrophic lateral sclerosis (ALS) patinets, we enroll ALS patients diagnosed by revised-Awaji-El Escorial criteria within 12 months after the clinical onset. First they are followed for 12 weeks with ALSFRSR scores, and only those who exhibit drops of 1-2 points are allowed to enter into the test period. A total of 128 patients are randomized and the half having placebo. They are blindly evaluated for drops of ALSFRS in 16 weeks, as the primary outcome. After this, all subjects receive methylcobalamin.
Eligibility: 20 Years and older, all genders, not accepting healthy volunteers
