People who drink six or more cups of coffee a day have a 53% increased risk of developing dementia and a higher risk of stroke, a new study reports.
Spending time performing household chores may help to improve brain health, especially for older adults. Researchers found older adults who spent more time engaging in housework had greater brain volume, specifically in the frontal lobe and hippocampus, brain areas associated with memory and cognition.
Children raised in areas with a high risk of lead exposure have decreased brain volume and problems with cognitive performance.
Young adults who faced extreme deprivation as children had, on average, an 8.6% smaller brain size than their peers who did not suffer from deprivation. The deprivation related changes in brain volume were associated with lower IQ and increased ADHD symptoms.
An individual's level of general knowledge is associated with structural brain network connectivity. Fluid intelligence is best predicted by cortex volume in males, and by functional network connectivity in females.
The common statin drug Simvastatin reduces brain atrophy and slows the progression of secondary progressive multiple sclerosis (SPMS). The effects appear to be independent of the drug's cholesterol-lowering effects.
Light physical activity has positive benefits for brain health as we age. Spending an hour participating in light intensity physical activity was associated with the equivalent of 1.1 years less brain aging. Every additional hour spent exercising was linked to higher brain volume.
Researchers report genetic influences on head circumference remain stable during development and are correlated with genetic factors which contribute to intracranial volume.
A new study reports children and teens who face chronic bullying have altered brain structure, as well as problems with anxiety and depression. Researchers found those who were bullies had structural changes to the putamen and caudate, contributing to the development of anxiety related behaviors and emotional processing.
