Cumulative Effects of Concussion History on Baseline Computerized Neurocognitive Test Scores: Systematic Review and Meta-analysis.

ABSTRACT:

Context

It is unclear whether individuals with a history of single or multiple clinically recovered concussions exhibit worse cognitive performance on baseline testing compared with individuals with no concussion history.

Objective

To analyze the effects of concussion history on baseline neurocognitive performance using a computerized neurocognitive test.

Data sources

PubMed, CINAHL, and psycINFO were searched in November 2015. The search was supplemented by a hand search of references.

Study selection

Studies were included if participants completed the Immediate Post-concussion Assessment and Cognitive Test (ImPACT) at baseline (ie, preseason) and if performance was stratified by previous history of single or multiple concussions.

Study design

Systematic review and meta-analysis.

Level of evidence

Level 2.

Data extraction

Sample size, demographic characteristics of participants, as well as performance of participants on verbal memory, visual memory, visual-motor processing speed, and reaction time were extracted from each study.

Results

A random-effects pooled meta-analysis revealed that, with the exception of worsened visual memory for those with 1 previous concussion (Hedges g = 0.10), no differences were observed between participants with 1 or multiple concussions compared with participants without previous concussions.

Conclusion

With the exception of decreased visual memory based on history of 1 concussion, history of 1 or multiple concussions was not associated with worse baseline cognitive performance.

Project description:BackgroundNeurocognitive testing is an important concussion evaluation tool, but for neurocognitive tests to be useful, their psychometric properties must be well established. Test-retest reliability of computerized neurocognitive tests can influence their clinical utility. The reliability for a commonly used computerized neurocognitive test, CNS Vital Signs, is not well established. The purpose of this study was to examine test-retest reliability and reliable change indices for CNS Vital Signs in a healthy, physically active college population.HypothesisCNS Vital Signs yields acceptable test-retest reliability, with greater reliability between the second and third test administration compared with between the first and second administration.Study designCohort study.Level of evidenceLevel 3.MethodsForty healthy, active volunteers (16 men, 24 women; mean age, 21.05 ± 2.17 years) reported to a clinical laboratory for 3 sessions, 1 week apart. At each session, participants were administered CNS Vital Signs. Outcomes included standard scores for the following CNS Vital Signs domains: verbal memory, visual memory, psychomotor speed, cognitive flexibility, complex attention, processing speed, reaction time, executive functioning, and reasoning.ResultsParticipants performed significantly better on the second session and/or third session than they did on the first testing session on 6 of 9 neurocognitive domains. Pearson r test-retest correlations between sessions ranged from 0.11 to 0.87. Intraclass correlation coefficients ranged from 0.10 to 0.86.ConclusionClinicians should consider using reliable change indices to account for practice effects, identify meaningful score changes due to pathology, and inform clinical decisions.Clinical relevanceThis study highlights the importance of clinicians understanding the psychometric properties of computerized neurocognitive tests when using them in the management of sport-related concussion. If CNS Vital Signs is administered twice within a small time frame (such as 1 week), athletes should be expected to improve between the first and second administration.
