Lymphatic dysfunction caused by traumatic brain injury may have long-term consequences

Written by Alice Bough (Future Science Group)

A research group from University of Virginia (VA, USA) has identified that mild traumatic brain injury (TBI) is associated with long-term impairment of lymphatic drainage in the meninges. It was revealed that previous damage to meningeal lymphatic vessels worsens the impact of TBI. The authors of the study, published in Nature Communications, propose that athletes and military personnel with head injuries may need to have longer recovery periods before returning to the field. In the study, a mouse model of mild TBI was utilized. Meningeal lymphatic function was monitored, as well as morphological changes to the lymphatic vasculature. It was...
