Severe childhood deprivation has longstanding impacts on brain size in adulthood
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.... Read More...
What the brains of people with excellent general knowledge look like
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. ... Read More...
Statins’ potential to treat MS unrelated to lowering cholesterol
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.... Read More...
Light, physical activity reduces brain aging
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.... Read More...
Genes with Large Effect on Head and Brain Size Discovered
Researchers report genetic influences on head circumference remain stable during development and are correlated with genetic factors which contribute to intracranial volume.... Read More...
How Bullying Affects the Brain
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.... Read More...
Bigger Brains Are Smarter, But Not By Much
Neuroimaging information reveals a small but significant positive association between brain volume and cognitive performance.... Read More...
Epilepsy Linked to Brain Volume and Thickness Differences
UCL researchers report epilepsy is associated with gray matter differences in thickness and volume in several brain regions.... Read More...
Little Wasp Bodies Means Little Wasp Brain Regions
Drexel University researchers reveal that while evolution may have allowed for bigger brains, some regions may not have kept up with the growth.... Read More...
