Mild Traumatic Brain Injury: A Prelude to CAPD

By Dennis A. Colucci, AuD, MA



People with mild traumatic brain injury (TBI), as well as survivors of moderate or severe TBI, can face long-term consequences. All central nervous system (CNS) structures are susceptible to damage, especially the auditory cortex (HJ Nov. 2009 issue, p. 17).


Worldwide, 42 million people experience a mild TBI each year, with the potential to develop neurodegenerative disease (Mol Cell Neurosci 2015;66[part B]:75- 80). Mild TBI is a significant public health issue, especially given that 75 percent of head injuries fall into this category, according to the Centers for Disease Control and Prevention (CDC; Report to Congress on Mild Traumatic Brain Injury in the United States: Steps to Prevent a Serious Public Health Problem).


An undetermined number of patients sustain minor head injuries that resolve physically but may cause underlying cognitive or auditory processing changes that go unnoticed and underreported.
