Individual Genotypes May Determine Efficacy of Alzheimer's Disease Drugs
Researchers have determined that a human gene present in 75% of the population is a key reason why a class of drugs for Alzheimer's disease seemed promising in animal studies only to fail in human studies. In different Alzheimer's disease patients, different mechanisms may be at work that determine whether or not a given therapy will be effective.
