What the trial is, and whether it could suit you
Alzheimer's disease (AD) manifests itself in cognitive decline, impaired ability to perform daily life, and a variety of behavioral and psychiatric symptoms, seriously endangering the health of the elderly. The prevalence and disability rates of AD in China remain high, and the lack of effective treatment options has brought a heavy burden to patients and their families. Early intervention is regarded as an effective strategy to improve clinical symptoms, delay disease progression and maintain current quality of life. The humanized monoclonal antibody lencanemab (Lecanemab) was approved by the U.S. FDA in July 2023 for the treatment of mild cognitive impairment or mild dementia caused by AD, and was officially approved in January 2024 in China. Lencanemab highly targets soluble and insoluble neurotoxic β-amyloid (Aβ) proteins, reducing pathogenic Aβ plaque deposition and preventing its f
