Original abstract
Pharmacological interventions for dementia include medications aimed at alleviating its core symptom: cognitive dysfunction. These medicines are known as anti-dementia drugs. As our understanding of Alzheimer's disease (AD) has advanced, the amyloid hypothesis stating that amyloid proteins are involved in the pathogenesis of AD has been proposed. To date, anti-dementia drugs such as cholinesterase inhibitors and N-methyl-D-aspartate receptor antagonists have focused on symptomatic treatment. In recent years, based on the amyloid hypothesis, the development of medicines that target either (1) the enzyme that produces amyloid beta (Aβ) or (2) Aβ itself, has been promoted as a treatment strategy for AD. In 2021, the first drug targeting Aβ, aducanumab, was launched in the USA. In Japan, lecanemab and donanemab are now available as monoclonal antibodies targeting Aβ. Additionally, medications have been used to manage the behavioral and psychological symptoms of dementia (BPSD), Parkinsonism, and rapid eye movement sleep behavior disorder. Furthermore, dementia is a major risk factor for delirium, which often occurs during the course of dementia. In this study, we introduce pharmacotherapy with anti-dementia drugs, BPSD treatment, and delirium.
