In a [press release about the study](), which was [published in the journal *Proceedings of the National Academy of Sciences*](), the University of California at Los Angeles explained that the synthesized molecule works much differently from current Alzheimer's drugs on the market. As the predominant field of study into the disease has noted time and again, the buildup of harmful amyloid plaques in the brain seems to be the primary driving factor in the progression of Alzheimer's. As such, researchers have tried various methods over the years to get rid of plaque in the process — but as [more recent studies have shown](), monoclonal antibodies that remove these plaques from the brain don't restore the cognitive function and memories lost to the disease. "They leave behind a brain that is maybe plaqueless," explained UCLA neurologist and study leader Istvan Mody, "but all the pathological alterations in the circuits and the mechanisms in the neurons are not corrected." Along with plaque buildup, early to mid-onset Alzheimer's is characterized by the slowing of gamma oscillations, which fire off electrical signals that stimulate essential recall functions such as remembering a phone number. That's where the new molecule, named DDL-920 after UCLA's Drug Discover Lab where it was synthesized, comes in. Using both "wild-type" mice and mice genetically modified to have Alzheimer's — which, as a sidebar, some say is an [ethically dubious practice]() — the UCLA researchers posited that DDL-920 could alter the process that puts the brakes on these important oscillations. After two weeks of oral administration of the drug containing the molecule, the Alzheimer's mice were able to recall maze escape routes at similar rates to their wild-type counterparts, and they also didn't exhibit any weird behavior after being given the medicine. As Mody notes, there's an immense amount of work left to be done to determine whether DDL-920 could be safe and effective for humans. If the researchers get there, however, it could have huge implications for other disorders characterized by disruptions in gamma oscillation, which include autism spectrum disorder, depression, and schizophrenia. "We are very enthusiastic about that," Mody said in the press release, "because of the novelty and the mechanism of action that has not been tackled in the past." **More on memory:** [*Journalist Says Trump Suffered* "*Severe Memory Problems*" *During Extensive Interviews*]() ## Author At Futurism, I've often been drawn to unpacking the narratives that underlie technological, scientific and medical progress, with a special interest in areas of conflict and ambiguity that end up setting agendas and steering the fates of both elites and the hoi polloi. I'm a committed generalist, but I often find myself returning to work involving NASA and the private space sector, the effects of AI on media and society, and the mechanics of the pharmaceutical industry, with a specific focus on the spread of GLP-1 drugs like Ozempic and Wegovy. Prior to Futurism, I worked for publications ranging from Media Matters and Truthdig to Raw Story and Bustle. I'm also the author of "Myspace Scene Queens," a 2024 title in Instar Books' acclaimed "Remember the Internet" series. My work at Futurism has been cited by outlets including the New Yorker, Slate, Nieman Lab, the Verge, the MIT Technology Review, the Sunday Times, and the Daily Beast. I grew up in North Carolina, attended the University of North Carolina at Asheville, and now live in Brooklyn, New York. In my free time, I'm an avid reader and music fan; you can probably find me at a local poetry reading, concert, underground rave, or DJ set. I'm the proud parent of an ineffable orange cat named Mee-Mow. ### Author social links [Bluesky]()
