The Centers for Disease Control estimates that 1.4 Million people yearly suffer a traumatic brain injury. When troops returned from the First World War suffering what was then called “Shell shock”, the first associations were made between chronic pain and brain injuries. As a Sacramento Brain Injury Lawyer, I have been well aware of how many of my clients suffering concussions or brain injuries also suffered from chronic headaches.
I saw confirmation of this correlation in a recent medical review of some 1100 Medline articles over the past 50 plus years. The study showed a prevalence of chronic headache pain in 56 percent of individuals suffering a brain injury, even a “mild” brain injury. The full article can be found here.
