This TED talk features neuropsychologist Kim Gorgons recorded live at Haddocks Mile High twenty eighteen.

A traumatic brain injury or TBI, is a disruption in brain function caused by an external blow to the head.

And when you hear that definition, you might think about sports and professional athletes, since it's the kind of injury we're used to seeing on the playing field.

And this imagery has really come to define TBI in the public consciousness. I myself do research on TBI and retired and college athletes. I stood on a TED stage in 2010 talking about concussions and kids sports.

So I have to say, as someone who researches and treats these injuries that I've been really gratified to see the growing awareness of TBI and specifically the short and long term risks to athletes.

Today, though, I want to introduce you to a larger but no less controversial group of people impacted by traumatic brain injury who don't often show up in the headlines.

I've come to recognize these inmates and probationers as surprisingly among the most vulnerable members of society.

For the last six years, my colleagues and I have been doing research that has completely changed the way we think about the criminal justice system and the people in it, and it may change the way you think about those things, too.

So I'll start with a shocking statistic.

50 to 80 percent of people in criminal justice have a traumatic brain injury, up to 80 percent in the general public in this room, for example, that number is less than five percent.

And I'm not just talking about getting your bell rung. These are the kinds of injuries that require hospitalization.

Most of them are the product of a physical assault and some of them are actually sustained in jail, all of these numbers are even higher among the women in criminal justice.

Almost every single woman in the criminal justice system has been exposed to interpersonal violence and abuse.

More than half of these women have been exposed to repeated brain injuries.

In this way, these women's brains look like the brains of retired NFL players, and they'll likely face the same risks for dementing diseases as they age.

The same risks. TBI, together with mental illness and substance abuse and trauma, makes it hard for people to think they have cognitive impairments like poor judgment and poor impulse control problems that make criminal justice a revolving door.

People get arrested and booked into jail. They oftentimes get into trouble while they're in there.

They get into fights, they fall out of their bunk, and then they get released and do stupid things like forgetting mandatory check ins and they get rearrested.

Statistically speaking, they're actually more likely to be rearrested than not.

A colleague calls this serving a life sentence 30 days at a time. And oftentimes these folks don't know why this is so hard for them, they feel out of control and frustrated.

So knowing that TVI is at the root of so many of these challenges, the mission for a group of us in Colorado has been to disrupt that cycle, to jam the revolving door.

So working together with my state and local partners, we crafted a plan to meet everyone's needs, the system, the inmates and probationers, my graduate students.

In this program, we assess how each person's brain works so that we can recommend basic modifications to make the system more effective and safer.

And here, when I say safer, I mean safer, not only for the inmates there, but safer also for correctional staff.

In some ways, this is such a simple approach, we're not treating the brain injury, we're treating the underlying problem that gets people into all of this trouble in the first place.

We do a quick neuropsychological screening tests to identify strengths and weaknesses in the way an inmate thinks.

Using that information, we write two reports.

One, a report for the system with specific recommendations on how to manage that inmate. The other is a letter to the inmate with specific suggestions for how to manage themselves.

For example, if our test results suggest that a probationer has a hard time remembering the things they hear, that would be an auditory memory deficit.

In that case, our letter to the court might suggest that that probation or get handouts of important information.

And our letter to that probationer would say, among other things, that they should carry a notebook to record that information for themselves.

Now, most importantly is that I pause here to be really clear about one point.

This program does not minimize responsibility or make excuses for anyone's behavior.

This is about changing longstanding negative perceptions and building self advocacy. It's actually about taking responsibility.

The inmates move from I am a total screw up.

I'm a loser to here's what I don't do well, and here's what I have to do about it.

And the system comes to see an inmate's problematic behavior as the things they can't do versus the things they won't do and that change seeing behavior as a deficit rather than outright defiance is everything in these settings.

So we hear from inmates around the country and they write, and more than anything, they want to know how to help themselves.

This is an excerpt from a letter from Troy in Virginia, an excerpt from a 50 page letter. And he writes, Can you tell me what you think of all the head traumas I've dealt with?

What can I do? Can you help me? Closer to home, we have thousands of stories like this and smart stories, stories that have a great outcome. Here's Vinnie. Vinnie was hit by a car when he was 15 and from that moment forward, spent more time in jail than in school with some basic skill building.

After our assessment revealed that he had some pretty significant memory impairments when he learned to use the alarm and reminder function on his iPhone to track important appointments.

And he keeps a checklist to break larger tasks into smaller, manageable ones, and with basic tools like that under his belt when he's been out of jail for two years, clean for nine months and recently back to work.

What's so striking for Vinny is that this is his first time off of court supervision since his injury more than 15 years ago, he made it out of the revolving door.

He says, now I can do anything. I just have to work a lot harder at it. And here's Thomas. Thomas has some pretty significant attention and behavior problems after an injury landed him in a coma for more than a month. After learning how to walk his first stop court, he couldn't imagine a future where he wasn't in trouble.

He now carries a calendar to avoid being held in contempt for missed court dates, and he schedules a break into his day every day to recharge before he gets agitated. And nobody knows the revolving door better than the person sitting at the front of the courtroom. This is my good friend and colleague, Judge Brian Boin. Now, Judge Bowman was already on a mission to make the system work for everyone.

And when he heard about this program, he saw the perfect fit.

He actually sits down with all of his prosecutors to help them see that there's basically two categories of defendants in the courtroom, the ones we're afraid of oftentimes, rightfully so, and the ones we're mad at.

These are the ones who miss all of their scheduled appointments and they blow through the best laid probation plans.

And Judge Boland believes that with a little more support, we could move people in this latter category, the maddening category, through and ultimately out of the system.

He proved that with Navy veteran Mike Judge Vaughn saw the correlation between Mike's history of a massive 70 foot fall and his long standing pattern of difficulty showing up on the right day for court appointments and complying with mandatory therapy requirements, for example, and instead of sentencing him to more and more jail time.

Judge Bohane sent him home with maps and checklists and handouts and recommended instead vocational rehabilitation and flexible scheduling for those therapists.

And with those supports, Mike's back to work for the first time since his injury while he was in the service, he's repairing relationships with his family.

And just last month, he graduated from Judge Barnes Veterans Court.

This program shows us the overwhelming prevalence of traumatic brain injuries and cognitive deficits and the accumulation of brokenness in the criminal justice system.

And it highlights the extraordinary power of resilience and responsibility. And Mike and Thomas and Vinnie, even Judge BO1 story, you saw the transformation made possible by a change in perception and some simple accommodations.

All told, in this program, these inmates and probationers come to see themselves differently.

The system sees them differently. And when you meet them in the community, I hope you see them differently to. Thanks, guys. For more TED talks, go to Ted Dotcom. PR ex.
