New study challenges nerve damage hypothesis in traumatic brain injury

October 14, 2019

Post-mortem scans of injured brains are causing researchers to question the hypothesis that blunt force trauma from traumatic brain injuries (TBI) causes nerve damage.

The scans, conducted by a team including researchers at the New York-based Cold Spring Harbor Laboratory (CSHL), have shown greater signs of blood vessel damage than nerve damage, and could influence how drugs are developed and treatments are implemented for TBI.

CSHL professor Partha Mitra said: “Nerve damage following traumatic brain injuries has been a majority point of view, and therapy as well as drug development has been targeted towards that.
