A Purdue-affiliated startup, MR-Link LLC, is developing a coin-sized, affordable device that once inserted into existing MRI machines could allow researchers and medical professionals to perform multiple imaging scans at once and more efficiently and effectively understand a patient’s physiology. Ranajay Mandal, a graduate student in Purdue University’s Weldon School of Biomedical Engineering, Nishant Babaria, graduate student in the School of Electrical and Computer Engineering, and Zhongming Liu, an assistant professor of electrical and computer engineering and of biomedical engineering, co-founded MR-Link to further develop and commercialize the technology.
MRI of the brain can detect potentially life-threatening brainstem damage in patients with epilepsy, suggesting the test could be used as a biomarker to identify those at risk for sudden unexpected death in epilepsy (SUDEP), new research shows. “When we looked at the brain stem of people who died from SUDEP, we saw that they had volume loss in certain regions of the brain stem, and those regions are involved in autonomic control, so control of breathing and heart beats, et cetera”, lead author, Susanne Mueller, MD, associate professor, radiology and biomedical imaging, University of California, San Francisco (UCSF), told Medscape Medical News.
The American Academy of Neurology (AAN) has released the first evidence-based guideline comparing procedures used for determining brain lateralization prior to epilepsy surgery and for predicting post-surgical language and memory deficits.
Sleep difficulties may be linked to faster rates of decline in brain volume, according to a study published in the September 3, 2014, online issue of Neurology-, the medical journal of the American Academy of Neurology. Sleep has been proposed to be “the brain’s housekeeper”, serving to repair and restore the brain. The study included 147 adults 20 and 84 years old. Researchers examined the link between sleep difficulties, such as having trouble falling asleep or staying asleep at night, and brain volume. All participants underwent two MRI brain scans, an average of 3.5 years apart, before completing a questionnaire about their sleep habits. A total of 35 percent of the participants met the criteria for poor sleep quality, scoring an average of 8.5 out of 21 points on the...
