The drug, lecanemab, was proven to moderately slow the disease in early stages. It also comes with the potential for some serious side effects, such as brain bleeding and brain inflammation.

While there are still many questions about the ultimate efficacy of the drug, lecanemab, Dr. Arash Salardini said it could provide a path forward for new Alzheimer's treatments, like AZT was for HIV.
