9/11 First Responders With Severe Debris Exposure Have Higher Risk Of Dementia, Study Finds
New research is giving a deeper look into how dust and debris from the fallen World Trade Center may play a role in the brain health of first responders. In the study, published Wednesday in JAMA Network Open, researchers at Stony Brook University in New York found severe exposure to building debris was significantly associated with a higher risk of dementia before age 65 versus those who weren't exposed or who wore personalized protective equipment such as masks or hazmat suits.

African Ancestry Genes Linked To Higher Risk For Alzheimer’s, Stroke
Black Americans are known to be at higher risk of some neurological disorders, and the reasons for this disparity remain unclear. Now, after examining the postmortem brains of 151 people, researchers in Baltimore have identified genes that may help explain why. In those people, who all identified as Black or African American, the scientists analyzed the influence of two different ancestries: African and European. They found that genes associated with African ancestry appear to affect certain brain cells in ways that could increase the risk of Alzheimer’s disease and stroke. (Hamilton, 6/12)

Alzheimer’s Indicators Track With Biological Changes In Brain
Using imaging reports to back up their findings, researchers have concluded that reports from patients and their partners about cognitive decline can be an early indicator of an accumulation of tau tangles, a hallmark of Alzheimer’s disease. “There is increasing evidence that individuals themselves or a close family member may notice changes in memory, even before a clinical measure picks up evidence of cognitive impairment,” said Rebecca E. Amariglio of the Department of Neurology at Brigham and Women’s Hospital and the senior author of the study. Results are published in Neurology, the medical journal of the American Academy of Neurology. (Bridger, 6/10)

When Mice With Alzheimer’s Inhaled Menthol, Their Cognitive Abilities Improved
Imagine a future where the smell of menthol could alleviate some of the worst symptoms of Alzheimer’s disease. This might sound like science fiction, but innovative new research is making it a potential reality. Scientists have discovered that when mice with Alzheimer’s inhaled menthol, their cognitive abilities improved. This unexpected finding highlights a potential new avenue for treating this debilitating condition. (Spencer, 6/11)
