The research project will clarify how sleep disordered breathing and Apolipoprotein (APOE) status affect cognitive decline in a population already at risk for accelerated decline-veterans with PTSD.
To fill this knowledge gap properly, we will conduct a longitudinal study and data include analytic techniques designed specifically to identify moderators and mediators of clinical change.
