Typical practices of obtaining new baselines every 2 years in the high school population can be applied to athletes with a history of special education or learning disorders (LD) and headache/migraine treatment, a recent study found. This study examined the test-retest reliability of the 4- and 2-factor structures (ie, memory and speed) of ImPACT (Immediate Post-Concussion Assessment and Cognitive Test) over a 2-year interval across multiple groups with premorbid conditions, including those with a history of special education or LDs (n=114), treatment history for headache/migraine (n=81), and a control group (n= 792).

Researchers found:

• Significant improvement on all 4 composites were observed for the control group over a 2-year interval, whereas significant differences were observed only on visual motor speed for the LD and headache/migraine treatment history groups.
• The 2-factor structure has potential to increase test-retest reliability.
