Alzheimer’s disease, an extremely prevalent neurological illness and the leading cause of dementia globally, is an extremely prevalent neurological illness and is the leading cause of dementia globally. There are a few treatment options for AD, and those that do exist only slightly reduce symptoms, even after several clinical studies. The formation of Aβ plaques, neuroinflammation, and hyperphosphorylated tau neurofibrillary tangles are the characteristics of AD. While monoclonal antibodies such as lecanemab, donanemab, and aducanumab have demonstrated potential in addressing Aβ, their clinical efficacy and safety over an extended period of time remain uncertain. Novel avenues for tackling the underlying genetic causes of AD have been made possible by developments in genome editing tools, most notably CRISPR-Cas9. In preclinical animals, CRISPR-Cas9 has effectively edited genes relevant to AD, such as APP and PSEN1, leading to decreased levels of Aβ and enhanced cognitive function. Additionally, base and prime editing, two precision gene-editing techniques, have increased the medicines' selectivity and decreased their offtarget effects. However, before clinical applications are deployed, challenges related to technology, ethics, and safety must be resolved. This review highlights how monoclonal antibodies, neuroinflammation research, and CRISPR-Cas9 have the potential to revolutionize therapy choices for AD by examining the most current developments in the field.
