Discusses the possibility of traumatic brain injury, which is very common in this type of IED blast.

Specifically:

There could be possible injuries that haven’t surfaced yet from the Boston Marathon bombing, such as brain injuries. The shock waves from bombs can be very powerful; easily enough to cause injury to your brain. Traumatic brain injury (TBI) occurs when sudden trauma occurs to the brain.

According to the National Institute of Neurological Disorders and Strokes, TBI symptoms can range from mild to severe and include: Headache, confusion, dizziness, blurred vision, ringing in the ears, bad taste in the mouth, fatigue, behavioral and sleep changes, and trouble with memory, concentration, and thinking. A person with a TBI may not appear to have an injury at first, as they don’t always lose consciousness or may only do so for a few seconds or minutes. As time passes and the headaches that don’t go away and other symptoms become more apparent, medical professionals may see more TBI injuries resulting from the attacks.

Traumatic brain injuries sound awful.
