What This Could Mean for Dementia and Brain Aging
The findings are still early, and the treatment has not yet been tested in humans. But the results point to a shift in how brain aging might be approached in a way that is not just managed, but reversed.
That possibility comes at a time when age-related cognitive disorders are becoming more common. In the United States, new dementia cases are projected to nearly double over the next four decades, rising from about 514,000 in 2020 to roughly 1 million by 2060.
The study also found that the treatment worked consistently across both sexes, a result that is not always seen.
“As we develop and scale this therapy, a simple, two-dose nasal spray could one day replace invasive, risky procedures or maybe even months of medication,” Shetty said.
Beyond aging, the same approach could potentially be used to support recovery after stroke or other brain injuries, where inflammation and cellular damage play a major role.
