IF patients with amnestic mild cognitive impairment (aMCI) are stratified by prefrontal cortex ADCY8 expression levels (high vs low tertiles) and tested on a virtual navigation task, THEN high-ADCY8 expressers will demonstrate ≥25% greater spatial accuracy during morning sessions compared to evening
Predicted outcome: High-ADCY8 tertile (n≥30) will show mean path efficiency of 0.78 ± 0.09 (SEM) in morning vs 0.61 ± 0.11 in evening sessions (paired t p<0.01). Low-ADC
Falsification: No significant circadian × ADCY8 expression interaction in repeated-measures ANOVA; or low-ADCY8 expressers show greater morning advantage than high-ADCY8 expressers.
