Abstract:
Subjective feedback about distractions or problems encountered during computerized assessment was provided by 538 out of a pool of 1659 high-school athletes who completed baseline testing using ImPACT (Immediate Post-Concussion Assessment and Cognitive Testing). Three types of feedback were included: (a) environmental, (b) computer-based (mechanical), and (c) instruction-based (associated with difficulty understanding test instructions). One-way analyses of variance were conducted and revealed relationships between greater symptom reporting and any type of feedback, environmental feedback, and instruction-based feedback. Increased symptom reporting was noted for female students. Additional relationships were noted between providing computer-based feedback and faster reaction time; and between history of concussion and providing instruction-based feedback. Athletes endorsing more symptoms at baseline scored significantly worse on ImPACT, as reflected in decreased visual memory performance. Results suggest that feedback provided during computerized assessment may yield information about symptom reporting and test-taking style, which may also be of particular interpretive utility when athletes minimize their symptoms.

Abstract:
OBJECTIVE: The objective of this study was to evaluate memory dysfunction and self-report of symptoms in a group of concussed high school athletes utilizing a computerized neuropsychological test battery. METHOD: Neuropsychological performance prior to and following concussion is compared with the test performance of an age-matched comparison group. Potentially important diagnostic markers of concussion severity are discussed and linked to recovery within the first week of injury. CONCLUSIONS: Mildly concussed high school athletes demonstrated significant declines in memory processes relative to a non-injured comparison group. Statistically significant differences between pre-season and post-injury memory test results were still evident in the concussed group at 4 and 7 days post-injury. Self-reported neurological symptoms such as headache, dizziness and nausea resolved by day 4. Duration of on-field mental status changes such as retrograde amnesia and post-traumatic confusion was related to the presence of memory impairment at 36 hours, 4 days and 7 days postinjury and was also related to slower resolution of self reported symptoms. The results of this study suggest that caution should be exercised in returning concussed high school athletes to the playing field following concussion. On-field mental status changes appear to have prognostic utility and should be taken into account when making return to play decisions following concussion. Athletes who exhibit greater than 5 minutes of on-field mental status changes have longer-lasting post-concussive symptoms and memory decline.
