摘要

Background

Alzheimer disease (AD) is the most common cause of dementia in the world with the prevalence expected to increase threefold to 152.8 million people by 2050. The current medications provide a short-term ameliorative effect, and this requires development of disease-modifying treatments, which address the biological pathogenesis.

Methods

This review assesses the changing neuropharmacological environment offering a critical analysis of anti-amyloid monoclonal antibodies and investigates the so-called expanding frontier of non-amyloid targets. It also examines the approaches of clinical trials and the trend of biomarker-based patient selection and precision medicine.

Results

Although β-site APP-cleaving enzyme 1 (BACE1) and secretase inhibitors did not achieve success in clinical trials because of mechanism-based toxicity and cognitive impairment, new monoclonal antibodies such as lecanemab and donanemab have shown high amyloid plaque clearance and reduced cognitive deterioration. Nevertheless, the treatments are associated with amyloid-related imaging abnormalities (ARIA). In addition to amyloid, studies are focusing on tau hyperphosphorylation, neuroinflammation through triggering receptor on myeloid cells 2 (TREM2) and NLR family pyrin domain containing 3 (NLRP3) and growth factor-mediated synaptic plasticity through brain-derived neurotrophic factor (BDNF).

Conclusions

AD treatment has entered the new era that demands a paradigm shift from monotherapies to multi-target cocktails. The future lies in precision neuropharmacology, where genetic stratification and individual biomarker analysis are used to provide the correct treatment at the most appropriate biological stage.
