Depression Symptoms In Alzheimer’s Could Be Signs For Cognitive Decline

walking
Depression symptoms in cognitively healthy older individuals together with brain amyloid, a biological marker of Alzheimer's, could trigger changes in memory and thinking over time, researchers from Massachusetts General Hospital (MGH) report. "Our research found that even modest levels of brain amyloid deposition can impact the relationship between depression symptoms and cognitive abilities. This raises …

Major Surgery Associated With Small, Long Term Decline In Brain Functioning

major surgery
Major surgery is associated with a small long-term decline in cognitive functioning — equivalent, on average, to less than five months of natural brain ageing, according to a study in The British Medical Journal. But the odds of substantial cognitive decline also increase after surgery — approximately doubling — although the likelihood of this is …

Garlic May Decrease Deficits In Aging Related Memory

garlic
Eating garlic helps counterbalance age-related changes in gut bacteria associated with memory problems, a new study conducted with mice indicates. The benefits come from allyl sulfide, a compound in garlic known for its health benefits. "Our findings suggest that dietary administration of garlic containing allyl sulfide could help maintain healthy gut microorganisms and improve cognitive …

Restoring Memory Function In Familial Alzheimer’s May Be Possible

genetic mutation
A new approach to Alzheimer's disease (AD) that may eventually make it possible to reverse memory loss has been revealed by a team led by University at Buffalo scientists. They found that by focusing on gene changes caused by influences other than DNA sequences — called epigenetics — it was possible to reverse memory decline …

Obsessive Compulsive Disorder Brains Stuck In A Loop Of Error Processing

inner speech
The brains of obsessive-compulsive disorder patients get stuck in a loop of "wrongness", that patients can't stop even if they know they should, new research suggests. This new analysis of brain scans from hundreds of people with OCD, and people without the condition, was larger than any previous study. It pinpoints the specific brain areas …

Microstructural Brain Alterations Caused By Playing High School Football

footbal cte
As little as one single season of high school football may be sufficient to result in microscopic changes in the structure of the brain, a new study by researchers at the University of California, Berkeley, Duke University and the University of North Carolina at Chapel Hill indicates. The researchers used a new type of magnetic …
