National Traumatic Brain Injury Research and Treatment Improvement Act of 2015

Requires the Centers for Disease Control and Prevention (CDC) to: (1) evaluate existing surveillance and data collection systems that track the incidence and circumstances of traumatic brain injury, including concussion; (2) establish a statistically sound, scientifically credible, and integrated National Traumatic Brain Injury Surveillance System; and (3) ensure that the System is designed in a manner that facilitates further research on brain injury.

Requires the CDC to make information and analysis in the System available to the public and ensure that privacy and security protections applicable to the System are at least as stringent as those under the Health Insurance Portability and Accountability Act.
