Primary |
Change in N100 Amplitude |
Obtained by EEG recording of N100 potential amplitude. This measures is subsequently linearly transformed to a standardized score on a 0-100 scale, with larger peak amplitudes and shorter peak latencies resulting in higher scores. Changes in brain vital sign scores are depicted within a radar plot format, with the transformation process preserving the essential ERP results but enabling practical, simplified interpretation. |
Baseline, Postseason (approximately 6 months). |
|
Primary |
Change in N100 Latency |
Obtained by EEG recording of N100 potential latency. Increased latencies are indicative of slower responses. Obtained by EEG recording of N100 potential amplitude.

Primary |
Change in P300 Amplitude |
Obtained by EEG recording of P300 potential amplitude. Increased amplitudes are indicative of larger signals. This measures is subsequently linearly transformed to a standardized score on a 0-100 scale, with larger peak amplitudes and shorter peak latencies resulting in higher scores.

Blood will be at a biomarker level and B-Synuclein will be investigated. The biomarker will be measured in Nanograms per Milliliter (ng/ml). |
Baseline, postseason (approximately 6 months). |
|
Primary |
Change in blood biomarker vWF. |
Blood will be at a biomarker level and Von Willebrand Factor (vWF) will be investigated. The biomarker will be measured in Nanograms per Milliliter (ng/ml). |
Baseline, postseason (approximately 6 months). |
|
Primary |
Change in blood biomarker SNCA. |
Blood will be at a biomarker level and A-Synuclein (SNCA) will be investigated. The biomarker will be measured in Nanograms per Milliliter (ng/ml). |
Baseline, postseason (approximately 6 months). |
|
Primary |
Change in blood biomarker BDNF. |
Blood will be at a biomarker level and Brain Derived Neurotrophic Factor (BDNF) will be investigated. The biomarker will be measured in Nanograms per Milliliter (ng/ml). |
Baseline, postseason (approximately 6 months). |
|
Secondary |
Change in King-Devick Test (KDT) scored |
A rapid number-naming test that requires individuals to read 3 numbered patters aloud as fast as possible, the resulting time if the KDT score. The post-season score is compared to the pre-season baseline. An increase in the number of seconds required to read the 3 number patterns is considered to be significant. |
