The Invisible Injury.

 I had the chance to speak with TBI survivor Tanner Johnson recently. Tanner suffered a TBI during an operation on a broken arm. His brain was not receiving enough oxygen and he went into a coma for two days. Most people think you get traumatic brain injuries from hitting your head, etc. This is not always the case. TBI's are "invisible" injuries and this can make understanding the behavior of TBI survivors difficult.  If TBI survivors had missing limbs or some other visible injury, this cue would help explain why they do things a little differently. Without these obvious cues, TBI survivors can come across as just being "weird" and instead of having compassion for TBI survivors there is often judgement. .
