At the Vanderbilt University Institute of Imaging Science (VUIIS), scientists are focusing on a previously understudied part of the brain and spinal cord — white matter. Their discoveries could lead to treatments that restore nerve activity through the targeted delivery of electromagnetic stimuli or drugs.
Women who have their ovaries removed before menopause, particularly before the age of 40, have reduced white matter integrity in multiple regions of the brain later in life.
The largest brain autopsy study of women who had experienced intimate partner violence reveals substantial vascular and white matter damage in the brain, but no evidence of chronic traumatic encephalopathy (CTE), the neurodegenerative disease recognized among male contact sports athletes who sustain repeated head trauma.
A study by researchers at Washington University School of Medicine in St. Louis reveals that household and community poverty may influence brain health in children. Childhood obesity and lower cognitive function may explain, at least partially, poverty’s influence on the brain.
New research published in Human Brain Mapping reveals sex differences and developmental changes in the brain’s white matter—which provides communication between different parts of the brain—in healthy, typically developing infants and 5-year-olds.
A study that assessed the brains of 99 World Trade Center (WTC) responders showed that WTC responders with cognitive impairment (CI) and post-traumatic stress disorder (PTSD) have a different presentation of the white matter in their brains compared to responders with CI without PTSD.
Children’s Hospital Los Angeles researcher Matthew Borzage, PhD, was part of an international project showing how the brain grows—and shrinks—over a lifetime. The growth charts will provide scientists with an invaluable benchmark for future brain development studies.
Scientists from the Uniformed Services University (USU), Emory University and the University of Vermont have found that cigarette smoking is linked to increased lesions in the brain’s white matter, called white matter hyperintensities. White matter hyperintensities, detected by MRI scan, are associated with cognitive decline and Alzheimer’s disease. These findings may help explain the link between smoking and increased rates of dementia and other forms of cognitive decline.
