Social Bonds Protect Aging Brains

Social isolation can potentially harm brain structure and cognitive performance, suggesting an increased risk of conditions like Alzheimer’s dementia.
A lack of quality social interaction can lead to a decrease in the hippocampus’s volume, crucial for memory formation and retrieval, and poorer cognitive performance.

APOE expression and secretion are modulated by mitochondrial dysfunction

This study presents compelling evidence that ApoE is upregulated in various models of mitochondrial respiratory chain dysfunction. The work is of fundamental interest for those studying neurodegeneration and the role of ApoE in Alzheimer's disease; future work will be needed to reveal the molecular basis of this dramatic phenotype.

Running Rewires the Aging Brain: Exercise Protects Memory Function

Physical activity, particularly running, has been found to rewire aging brains, helping to preserve memory functions.
Long-term running keeps older neurons wired, potentially preventing age-related memory loss and neurodegeneration.

Long COVID’s Lingering Impact: Brain Function Changes Can Persist for Months

People with long COVID have abnormal brain activity during memory tests, months after their initial COVID-19 infection, with less activity in the regions normally used for memory tasks, but more activity in other areas of the brain.

Cognitive Decline May Be Triggered by Astrocyte Dysfunction

A new study reveals astrocyte dysfunction may be a driver of cognitive decline and memory loss in those with dementia. This may be caused by a protein build-up in the astrocytes that appears to trigger abnormal antiviral activity that results in memory loss.
