Study shows for the first time that lithium plays an essential role in normal brain function and can confer resistance to brain aging and Alzheimer’s disease. Scientists discovered that lithium is depleted in the brain by binding to toxic amyloid plaques — revealing a new way Alzheimer’s may begin. A new class of lithium-based compounds avoids plaque binding and reverses …

A recent study from Harvard Medical School asks whether the element lithium might be a key factor in whether someone develops Alzheimer’s disease. Led by Dr. Bruce Yankner, professor of genetics and neurology at Harvard Medical School, the almost-decade long study says it is the first to show that lithium is found naturally in the brain in small amounts and …

Given that, worldwide, one in 10 people older than 65 has Alzheimer’s disease (the most common cause of dementia), it’s not at all surprising that scientists are researching every possible avenue for treatment and prevention. One area where they’re looking is supplements. For example, a recent study found that taking vitamin B-12 as you get older could protect against dementia. …

Did you know that 94 percent of people with posterior cortical atrophy (PCA) problems develop Alzheimer’s disease? While the condition is rare, the link between ocular changes and cognitive decline isn’t. Previous studies have examined the impact of retinal vascular health on brain function—which supports theories that the eyes are a gateway to better understanding the brain. And now, scientists …

People carrying two copies of ‘Alzheimer’s gene’ lowered risk by 35% via diet changes Updated: 4:34 PM EDT Aug 25, 2025 Editorial Standards ⓘ Closely following the Mediterranean diet lowered the risk of dementia by at least 35% in people with two copies of the APOE4 gene, a major risk factor for Alzheimer’s, according to a new study.”We followed over …

Summary: Scientists have discovered that a toxic complex formed between NMDA receptors and TRPM4 channels drives neuron death in Alzheimer’s disease. Using a novel molecule called FP802, researchers were able to break apart this “death complex” in mice, preventing cognitive decline, synapse loss, and mitochondrial damage. The treatment also reduced amyloid buildup, suggesting it could offer broader protection than existing …

Summary: Eye exams could help detect Alzheimer’s disease years before symptoms arise. By studying mice with a common genetic mutation, researchers found abnormal changes in retinal blood vessels that paralleled brain changes linked to dementia risk. Because the retina functions as an accessible extension of the brain, these findings highlight its potential as a powerful biomarker. The research paves the …

It was then that Staci went to her primary care practitioner with her symptoms and suspicions, and got further testing done as she shared in her TikTok. She also emphasized how she had to really advocate for herself. “I remember she said, ‘Early-onset Alzheimer’s is really rare at your age, but let’s send you to a neurologist specializing in memory …

A new study highlights advantages of the Mediterranean diet in reducing risk of Alzheimer’s. The findings are especially significant for individuals of highest genetic risk. The diet is largely plant-based, with lots of fruits, vegetables, whole grains, nuts and beans. The food that people choose could have a powerful impact on the risk of developing dementia. That’s according to a …

Eating Mediterranean-style could help guard against dementia, even for those most at genetic risk. Credit: Shutterstock A large-scale study found that following a Mediterranean-style diet significantly reduces the risk of dementia, particularly in people genetically predisposed to Alzheimer’s. Mediterranean Diet Linked to Dementia Risk Reduction A new study led by investigators from Mass General Brigham, Harvard T.H. Chan School of …
