Alzheimer’s disease: An overview of the current treatments

Alzheimer’s disease (AD) affects millions of people around the world and although there are treatments that help control symptoms and slow down the progress of the disease, there is still no cure. Current treatments include three acetylcholine inhibitors, a glutamate inhibitor and a combination of the two. Due to the failure of hundreds of clinical trials with monotherapies, multitarget treatments are currently being investigated that consider both brain and peripheral factors. Gene therapy is one of the most promising therapies to treat and prevent the development of AD. Nowadays, there is no available medical treatment based on gene therapy to treat AD; however, there are treatments in phase 1 and phase 2 clinical trials with promising results. In this review, we will focus on the most important gene therapy treatments, CERE-110 (adeno-associated virus AAV2-Nerve Growth Factor), Intracerebral AAV gene delivery of APOE2 and gene therapy using PPARγ-coactivator-1α(PGC-1α)
