Alzheimer’s Association announces new research grants to study potential drug therapies Many educational researchers and pharmaceutical companies have identified new Alzheimer's medication therapy applicants, but lack the funding to move them into human testing. At the same time, few funding resources support early-phase clinical drug trials. As a total result, too many promising research stall out early in the discovery process. Today, the Alzheimer's Association announces new grant awards for five early-phase clinical trials attempting to period this troublesome gap in study.
