26 f l o r i d a d o c t o r Mayo Clinic Develops New Technologies to Improve Treatment for Stroke Patients Artificial Intelligence and "Telestroke" Technologies help save valuable time and improve brain function Mayo Clinic Neurologist, Dr. David Freeman, has helped develop Artifical Intelligence that could soon improve outcomes for people who suffer from a certain kind of stroke, called an intracerebral hemorrhage, or ICH. Currently, patients with an ICH go to a hospital with symptoms, get a CAT Scan, then have to wait for results and for doctors to figure out how to address it. During all that time, their risk of dying increases every minute. "It's been estimated 1.9 million neurons die for every minute a stroke patient is having a stroke," Dr. Freeman says. Dr. Freeman's team at Mayo is developing an AI system that can help cut down time and damage to the brain. "A patient with an ICH will have that CAT scan analyzed by the machine learning and output specific treatment in- terventions for better outcomes," Dr. Freeman says. He estimates AI could help save up to 30 min- utes of precious time, which he hopes will save more lives. Additionally, Stroke Telemedicine, also called "telestroke," is being extended from emergency departments into emergency medical vehicles. It works much like FaceTime or Skype, but instead of communicating with friends and family, it's connecting emergency patients with neurologists to determine if the patient is having a stroke. "e cool part about this is that Mayo physicians will be [in] a moving ambulance to examine pa- tients while they're traveling to our Mayo hospital," says Dr. Freeman. e time saved with telestroke oen is vital to prevent major neurological disabilities and can be a matter of life and death. "We measured previously that [it] saved 7½ minutes. And we know that's 1.9 million brain cells saved per minute," says Dr. Freeman. "So you can do the math about how many millions of brain cells that can potentially be saved." Having a prompt telestroke evaluation and assessment increases the possibility of adminis- tering treatment in time to reduce stroke-related disabilities.
