Alzheimer's disease (AD) is a deadly neurological condition associated with symptoms of memory loss and progressive cognitive deterioration. As an age-related disorder, it has been challenging the medical departments globally, leading to profound social and economic implications. Although its pathogenesis is not fully understood, many scientists have reached a consensus on the relationship between amyloid-beta protein peptide accumulation and cognitive decline. Aducanumab, an innovative monoclonal antibody treatment, targets the aggregated plaques and seeks to promote clearance to delay disease progression. Unlike conventional medications, aducanumab is the first therapy that allows for direct binding with amyloidogenic agents and, theoretically, leads to the activation of the immune system. In this review, the author provides an overview of Aducanumab's mechanism and potential disadvantages, highlighting its critical role in slowing disease progression and emphasizing the controversy surrounding the accelerated approval. This paper also introduces investigational therapies that offer promising avenues offering hope for improved AD treatments and better quality of life for those affected. By revealing Aducanumab's journey from research laboratories to the clinic, the global medical community can better understand the pathophysiology of AD, which further pave the way for a more comprehensive approach to managing this devastating neurological condition in the future.
