Could brain swelling play a protective role following traumatic brain injury?

Managing brain swelling that occurs after a traumatic brain injury (TBI) is crucial for individuals, as the increase in pressure inside the skull can potentially be life-threatening. However, a collaborative study from researchers at University of Utah Health (UT, USA) has revealed that this swelling may also be beneficial for protecting the brain. The study, which has been published in The Journal of Clinical Investigation, used animal models to reveal that swollen neurons are less likely to display troublesome patterns of overactivity associated with long-term complications of TBI than neurons that are treated after injury to reduce swelling. “This data...
