Motivation Is Affected by Oxidative Stress, but Nutrition Can Help

Higher levels of glutathione in the nucleus accumbens correlated with better and more steady performance in motivation-based tasks. Findings suggest improvements in accumbal anti-oxidant function that can be acquired via diet or supplementation may be a feasible approach to help boost motivation.

New Insights on ALS May Point To a Potentially Promising Treatment Strategy

Post-mortem studies of brain tissue from ALS patients reveal an abnormal form of tau is present in novel brain areas, and the tau interacts with DRP1. The tau appears to cause the brain cell's mitochondria to fragment and increase oxidative stress. Reducing tau reversed the effect, decreasing oxidative stress and mitochondrial fragmentation.

Fat Cells Found to Play a Central Role in Cognitive Decline and Neurodegeneration

A new study reveals how adipocytes, or fat cells, play a role in cognitive decline and increased neurodegeneration risks. Using genetically modified mouse models, researchers found oxidative stress through exposure to a Western diet increased the production of inflammatory cytokines confined to adipocytes and altered protein markers of memory and cognition in the hippocampus.
