Subset of brain immune cells identified, linked to cognition and memory

Researchers have identified a subset of microglia, the brain's immune cells, called ARG1+ microglia (shown here in yellow), surrounded by regular microglia (red)

A new study has discovered the important role that a subset of microglia, the brain’s immune cells, plays in early brain development, cognition and memory. The finding gives us a better understanding of how these cells work and could pave the way for new treatments for neurodegenerative conditions like Alzheimer’s disease.

Weekend cheat meals linked to cognitive impairment and poor gut health

Bad news if you love a nice weekend cheat meal: scientists have found evidence that “diet cycling” between healthy food Monday to Friday, followed by a weekend reward of greasy takeout, could trigger cognitive impairment and poor gut health.Continue Re… Continue reading Weekend cheat meals linked to cognitive impairment and poor gut health

Nanowire networks can learn and remember like a human brain

Nanowire networks mimic the networked structure of the human brain. But can they learn and remember like a human brain can? New research indicates they can.Continue ReadingCategory: TechnologyTags: Nanowires, Brain, Memory, Learning, University of Sydney Continue reading Nanowire networks can learn and remember like a human brain

Tickling the ivories may improve age-related cognitive decline

As we age, our brains naturally atrophy, and we experience cognitive decline. New research suggests that listening to music or playing a musical instrument may improve cognitive functioning in healthy older people.Continue ReadingCategory: Health &… Continue reading Tickling the ivories may improve age-related cognitive decline

Clear chemical connection between physical activity and brain health

Scientists unlock key chemical mechanisms that link brain health with muscle use

The link between physical activity and brain health is not new, with many studies showing how exercise can boost function, from easing depression to staving off cognitive decline. Now, scientists have shown in cell studies that the connection may be more direct, which opens the door to more targeted physical therapies for brain health and potential treatment of neurodegenerative conditions.

Protocol predicts Alzheimer’s 10 years in advance with 80% accuracy

The number of people with dementia is set to almost double every 20 years, according to Alzheimer's Disease International

In seeking a safe yet effective way to predict Alzheimer’s disease, researchers found a sugar molecule in the blood of affected patients. When combined with a simple memory test and genetic analysis, the research team was able to predict the onset of the condition up to a decade in advance with a significant degree of accuracy. The protocol could soon join others in helping scientists spot Alzheimer’s in advance of its symptoms and take steps to halt its progression.
