Dr. Mark Cilo, who passed a couple of years ago, but worked in intensive care at St. Anthony Hospital with people with traumatic brain injuries, spoke in 2007 at the Brain Injury Association of Colorado's annual Vail Conference, on "Early Recovery from Severe Diffuse Brain Damage: One Neurologist's Perspective."

This speech is still a good primer on various types of brain injuries, how doctors consider who is in a "vegetative state" and who is likely to regain consciousness and improve.

This 58 minutes is short of the entire speech, but is featured here with Dr. Mark Cilo's expressed permission, and the permission of the Brain Injury Alliance of Colorado.
