[Alzheimer's disease: what's new in 2023]

The increasing prevalence of Alzheimer's disease in the general population presents a number of medical, economic and social challenges for the years to come. After 20 years of research with no new treatment option, a new class of drugs is set to be introduced in Europe. Anti-amyloid drugs, which are already available in the United-States, slow the disease progression by targeting the biological processes causing the disease, unlike the symptomatic treatments that are currently available. However, their precise indications and the monitoring of their adverse events are still to be defined. Several other drugs are in advanced stages of development, such as those targeting the tau protein or neuroinflammation, suggesting that the management of the disease will be quite different in the years to come.
