UCLA Health researchers have identified and synthesized a molecule, DDL-920, that was shown to restore cognitive functions in Alzheimer's disease model mice by jump-starting the brain's memory circuitry. While current FDA-approved drugs like lecanemab and aducanumab remove harmful plaque and slow cognitive decline, they do not restore memory. DDL-920, however, offers a novel treatment by targeting fast-firing neurons essential for memory and cognition.
