A double-blind, placebo-controlled crossover study of ganglioside GM1 treatment for Alzheimer's disease
C Flicker, S H Ferris, D Kalkstein, M Serby. The American journal of psychiatry, 1994-01
Topic: Drug trials: efficacy and safety
In a double-blind trial, 12 patients with probable Alzheimer's disease were treated for 6 weeks with placebo and 6 weeks with monosialoganglioside (GM1) (100 mg/day i.m.), which potentiates the actions of nerve growth factor. GM1 failed to produce significant improvement in patients' cognitive test performance, suggesting that this is not a viable approach to the treatment of cognitive deterioration in Alzheimer's disease.
Key findings
- GM1 failed to produce significant improvement in patients' cognitive test performance, suggesting that this is not a viable approach to the treatment of cognitive deterioration in Alzheimer's disease.

How this study scored 68/100
Published in a peer-reviewed journal, and it is a randomised controlled trial. Scored zero for effect reported because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 38 of the 56 points we could judge it on, which is 68 out of 100.
