Talk:Secondary mania

"Closed brain injury"
"One of the primary documented causes of secondary mania is traumatic brain injury, also called closed head injury."

I'm a layperson but I've noticed that our articles say that closed head injury is not the same as, but rather a subtype of traumatic brain injury. So which is true? And what is then "closed brain injury"?  Daß &thinsp;  Wölf  20:06, 26 April 2018 (UTC)
