A concussion is often characterized as a temporary brain injury associated with headache, dizziness and memory problems; however emerging neuroscience research has suggested that it has evident effects on the brain's ability to process sound and speech, extending beyond the anticipated symptoms. More specifically, causing difficulty in listening and communicating which possesses the question if hidden symptoms of brain injuries and often explained away by fatigue and distraction?
A few weeks ago I had the opportunity to listen to Jennifer Krizman’s presentation on the auditory biological markers of concussion in children, where she discussed how concussions impact the way the brain processes speech. She studied frequency following response, which captures how accurately the brain responds to sound. Her presentation and emergent dissolves suggest that concussion can have a more significant effect on the sensory processing system compared to traditional symptom-dependent diagnoses.
Similar findings are studied in a recent study tilted Persistent post-concussion symptoms include neural auditory processing in young children which explained how concussions influence auditory processing after initial symptoms seem to improve. The researchers found that children with concussions have weaker neural encoding of speech sounds, specifically for pitch-related cues which are integral in unders†ådning everyday speech. These findings support Kriman’s idea that the effect of concussion can still be present in the brain after symptoms seem to improve, which indicates recovery can not be solely judged by symptom reports.
