Military personnel firing powerful weapons face risks from blast waves that create a surge of blood to the brain, potentially damaging critical areas such as the brainstem and cerebellum. Unlike mere head impacts, these blasts cause profound disruptions to blood flow, resulting in various neurological issues such as decreased brain volume, increased inflammation, and impaired neuronal connections. These effects are challenging to assess in veterans, but they suggest significant long-term consequences, often manifesting in conditions like uncontrolled blood pressure, highlighting the need for deeper understanding of blast-related brain injuries.
When military personnel fire certain powerful weapons, they are exposed to a blast wave that sends blood surging from the body to the brain.
In animals, there is now strong evidence that these structures can be damaged by blast exposures that disrupt blood vessels.
There are these long lasting cumulative effects, suggesting a decrease in brain volume, an increase in brain inflammation and disrupted connections between neurons.
A blast isn't just like a blow to the head, when it comes to brain injury. A head impact tends to injure structures near the surface.
