Current approaches in the treatment of Alzheimer's disease.

Abstract

The management of Alzheimer's disease (AD) has been a long-standing challenge and area of interest. Advances in knowledge of the pathogenesis of disease and an increase in disease burden have prompted investigation into innovative therapeutics over the last two decades. This article reviews the various treatments of AD including those targeted towards cholinergic deficiency, oxidative stress, the amyloid cascade, inflammation, and excitotoxicity. Second generation cholinesterase inhibitors remain the preferred therapy for early and intermediate AD while the glutamate antagonist, memantine, is also approved for advanced stages of disease. Antioxidants may delay disease progression, while data on other experimental therapies remain equivocal at best. Gene therapy directed at neurotropins is currently under investigation with some intriguing preliminary results; however, the number of patients examined is too few to be conclusive. Drugs directly targeting amyloid-beta, particularly the amyloid-beta vaccine, continue to be investigated and their forthcoming results are eagerly anticipated.
