Pittsburgh, August 22, 2016 -- The U.S. Food and Drug Administration today permitted marketing of two new devices to assess a patient’s cognitive function immediately after a suspected brain injury or concussion. The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT®) and ImPACT Pediatric® are the first medical devices permitted for marketing that are intended to assess cognitive function following a possible concussion. They are intended as part of the medical evaluation that doctors perform to assess signs and symptoms of a head injury.
ImPACT and ImPACT Pediatric are not intended to diagnose concussions or determine appropriate treatments. Instead the devices are meant to test cognitive skills such as word memory, reaction time and word recognition, all of which could be affected by a head injury. The results are compared to an age-matched control database or to a patient’s pre-injury baseline scores, if available.
“These devices provide a useful new tool to aid in the evaluation of patients experiencing possible signs of a concussion, but clinicians should not rely on these tests alone to rule out a concussion or determine whether an injured player should return to a game,” said Carlos Peña, PhD, MS, director of the division of neurological and physical medicine devices at the FDA’s Center for Devices and Radiological Health.
"This is a very important step in our testing and treatment of concussions," said Joseph Maroon, MD, concussion expert, Pittsburgh Steeler neurosurgeon and Heindl Scholar at the University of Pittsburgh. "With ImPACT Pediatric, we now can test the millions of kids between 5 and 12 heretofore who had no test for baseline concussions."
Along with Michael Collins, PhD, Dr. Maroon helped develop ImPACT in the late 1970s after he was challenged by former Pittsburgh Steeler coaching great Chuck Noll to come up with up a more accurate, quantatitive analysis of head injuries. Over 10 million baseline tests have been performed since ImPACT was computerized in the late 1990s.
ImPACT software runs on a desktop or laptop and is intended for those ages 12 to 59, while the ImPACT Pediatric runs on an iPad and is designed for children ages 5 to 11. Only licensed health care professionals should perform the test analysis and interpret the results.
Traumatic brain injuries account for more than two million emergency room visits in the United States each year, according to the U.S. Centers for Disease Control and Prevention, and contribute to the deaths of more than 50,000 Americans. A significant percentage of these injuries are considered to be mild. A concussion is considered to be a mild traumatic brain injury.
The manufacturer submitted over 250 peer-reviewed articles, of which half were independently conducted clinical research studies. The research publications analyzed the scientific value of the ImPACT devices including the devices’ validity, reliability and ability to detect evidence of cognitive dysfunction that might be associated with a concussive head injury. The FDA concluded that these studies provide valid scientific evidence to support the safety and effectiveness of the ImPACT and ImPACT Pediatric devices.
The FDA reviewed the ImPACT device through its de novo classification process, a regulatory pathway for novel, low- to-moderate-risk medical devices that are first-of-a-kind, for which special controls can be developed, in addition to general controls, to provide a reasonable assurance of safety and effectiveness of the devices. The device is manufactured by ImPACT Applications, located in Pittsburgh.
The FDA, an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices. The agency also is responsible for the safety and security of our nation’s food supply, cosmetics, dietary supplements, products that give off electronic radiation, and for regulating tobacco products.
