However, the effects of primary blast injury to the brain are not well understood.
Primary blast injury is thought to result from these blast wave-induced changes in atmospheric pressure, which is a form of barotrauma.
The vulnerability of the brain to secondary and tertiary blast injury is clear, but whether primary blast injury has direct effects on the brain remains unresolved.
Thus, in limited experimental studies, exposure of animals to primary blast injury suggests structural changes occur in the brain that can lead to neurological impairment.
Animal experiments using blast injury models to study primary blast injury are very limited but suggest a number of pathological changes in the brain, such as outer-layer cortical neuronal and diffuse white matter damage, including changes in myelin and axonal structure.
Primary blast injury (PBI) is caused by the blast wave itself with changes of atmospheric pressure.
