Lower brain volumes found in patients with both MS and obstructive sleep apnea
DENVER — In adults with multiple sclerosis, obstructive sleep apnea increases brain atrophy independent of obesity, a common comorbidity, according to a poster at the American Academy of Neurology annual meeting.
White, gray matter MRI abnormalities linked to risk for late-onset epilepsy
PHILADELPHIA — In older adults, the presence of white and gray matter abnormalities on MRI is linked to greater risk for late-onset epilepsy, according to a poster presentation.
Disparities in adversity linked to differences in brain structure of Black, white children
Black children on average undergo more family conflict, material hardship and traumatic events than white children, resulting in differences in gray matter volume in key brain regions and disorders such as PTSD, data show.
Reproductive history events in midlife women may offer protection against brain aging
Reproductive history events indicating more estrogen exposure correlated with larger gray matter volume in midlife women, according to a study published in Neurology.
COVID-19 impacts gray matter volume, especially among those with fever, receipt of oxygen
Patients with COVID-19 experienced changes in gray matter volume, especially those with fever and those who received oxygen therapy, according to findings from a multivariate, observational study published in Neurobiology of Stress.
Gray matter atrophy differs among MS phenotypes
Researchers who characterized components of gray matter atrophy in MS found patterns that varied by clinical phenotype, according to results published in Neurology.
