Abstract
Almost three decades after the publication of the first clinical studies with tacrine, the pharmacological treatment of Alzheimer's disease (AD) remains a challenge. Randomized clinical trials have yielded evidence of significant - although modest and transient - benefit from cholinergic replacement therapy for people diagnosed with AD, and disease modification with antidementia compounds is still an urgent, unmet need. The natural history of AD is very long, and its pharmacological treatment must acknowledge different needs according to the stage of the disease process. Cognitive and functional deterioration evolves gradually since the onset of clinical symptoms, which may be preceded by several years or perhaps decades of silent, presymptomatic neurodegeneration. Therefore, the pharmacological treatment of AD must ideally comprise both a symptomatic effect to preserve or improve cognition and a disease-modifying effect to tackle the progression of the pathological process. Primary prevention is the ultimate goal, should these strategies be delivered to patients with preclinical AD. In this article, we briefly address the pharmaceutical compounds that are currently used for the symptomatic treatment of AD and discuss the ongoing strategies designed to modify its natural course.
