Alzheimer's Breakthrough: Could a Common Element Hold the Key to Prevention?
Harvard research reveals lithium — long known as a mood stabiliser — is naturally present in the brain, and its depletion may be one of the earliest signs of Alzheimer's disease. Clinical trials are now on the horizon.
For the 50 million families worldwide touched by Alzheimer's disease — including more than 60,000 people living with dementia in Scotland alone — any glimmer of hope is precious. Now, a decade-long investigation by Harvard Medical School may have uncovered one of the most promising leads in years: a humble element called lithium.
Professor Bruce Yankner and his team at Harvard have discovered that lithium isn't just a psychiatric medication — it occurs naturally in the brain and plays a vital role in keeping our neurons healthy. More remarkably, their research shows that lithium depletion is one of the very earliest changes detectable in people developing Alzheimer's.
"I try to provide hope," Yankner told the Harvard Gazette. And for once, the science may justify it.
