A new study that links the location of brain injury to levels of depression in patients following the injury has identified two distinct brain networks; one associated with increased depression symptoms and one associated with decreased depression symptoms.
Damage to the white matter is more predictive of cognitive impairment after brain injury A new University of Iowa study challenges the idea that gray matter (the neurons that form the cerebral cortex) is more important than white matter (the myelin covered axons that physically connect neuronal regions) when it comes to cognitive health and function. The findings may help neurologists better predict the long-term effects of strokes and other forms of traumatic brain injury. The most unexpected aspect of our findings was that damage to gray matter hubs of the brain that are really interconnect...
Damage to white matter linked to worse cognitive outcomes after brain injury: Study ANI | Updated: May 08, 2021 08:37 IST Washington [US], May 8 (ANI): A new University of Iowa study challenges the idea that grey matter (the neurons that form the cerebral cortex) is more important than white matter (the myelin covered axons that physically connect neuronal regions) when it comes to cognitive health and function. The findings may help neurologists better predict the long-term effects of strokes and other forms of traumatic brain injury. "The most unexpecte...
