Immunotherapy for Alzheimer's disease
Morgan D.. Journal of Alzheimer's disease : JAD, 2006-01-01
Topic: Amyloid, tau and blood-test diagnosis
A primary goal of research on Alzheimer's disease is to develop disease modifying therapeutics. The amyloid cascade hypothesis has focused the initial efforts on methods to reduce amyloid. One surprising approach that has shown considerable success in mouse models and has hinted at benefits in human trials is anti-Abeta immunotherapy. Schenk first showed the amyloid reducing potential of active immunization in 1999. This prompted our group and that of St. George-Hyslop to investigate whether active immunization would similarly retard the memory deficits that develop in amyloid depositing transgenic mice. Contrary to our initial predictions of premature memory dysfunction due to inflammation, vaccination protected amyloid depositing mice from developing memory deficits. Subsequent studies found that passive immunization could reverse memory deficits, even when administered for short periods. These encouraging findings led to a trial of an Abeta vaccination in Alzheimer patients. The trial was cut short due to meningoencephalitic symptoms in 6% of patients, yet, in a subset of patients, those developing brain reactive antibodies benefited from slower rates of cognitive decline. These observations have accelerated the development of passive immunization protocols and safer vaccines. At this time, anti-amyloid immunotherapy stands poised to be the first test of the amyloid hypothesis in the treatment of Alzheimer disease.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded 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 and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
