"I don’t know if this has been said but a large factor that contributed to ‘shell shock’ was actually the concussive force of artillery pounding soldiers’ brains against their skulls and bruising their brains.
Obviously PTSD played a large factor too but the physical effect of the shelling is not to be ignored in these cases."
