It was a tough time. After getting the brush-off from an Army neurologist, I tried and failed to explain to my friends and loved ones that my brain might not work right any more. But how would I know for sure, and how could they possibly understand? There’s a tragic caveat to the comic — something I learned only recently. One of the Pakhab-e-Shana blast victims — I won’t say which — has begun to show signs of a Traumatic Brain Injury, including chronic confusion and memory loss. But he hasn’t been able to convince the Army that his injury is real.
