Women who have undergone menopause have more white matter intensities in the brain than pre-menopausal women and men of the same age.
Neuroimaging study reveals those with anorexia have noticeable reductions in cortical thickness, subcortical volume, and cortical surface area. The reductions are between 2 to 4 times larger than abnormalities in brain size and shape in those with other mental illnesses.
Neuroimaging study reveals those suffering from Gulf War Syndrome who experience chronic pain have increased volume in brain areas associated with pain processing and smaller volume in areas associated with pain regulation.
White matter may be the key to understanding dementia, TBI, and numerous other neurological disorders.
Lower gray matter volume in the brain is indicative of a higher risk of developing mental health disorders including depression and psychosis. However, those with slightly greater gray matter volume were more likely to recover from their disorders. Researchers believe reduced gray matter volume may be linked to higher levels of inflammation, reduced concentration, and other cognitive impairments associated with disorders like schizophrenia.
Children with binge eating disorders have differences in gray matter density compared to their peers who do not experience overeating disorders.
Researchers have discovered a link between anxiety behaviors and PTSD to an increase in myelin in the brain's gray matter.
Learning a new language or playing a musical instrument has a positive impact on cognitive function in the aging brain, researchers report.
Aerobic exercise was associated with positive white matter changes in the brain for older adults.
A new technique allowed researchers to evaluate the distribution of lithium levels in the human brain. Findings revealed those without depression had significantly more lithium in the brain's white matter than in gray matter. By contrast, those with depression or suicidal ideations had more balanced distribution of lithium in both white and gray matter.
Gray matter was reduced in areas of the frontal gyri of patients with COVID-19. Significant gray matter reductions were seen in those who received oxygen therapy and in those who reported fever. The findings suggest coronavirus affects the frontotemporal brain network due to reduced oxygen and fever.
Damage to highly connected regions of white matter in the brain following injury is more predictive of cognitive impairment than damage to highly connected gray matter hubs.
