Double-Blind, Placebo-Controlled, Functional Neuroimaging Study of Armodafinil (200 mg/Day) on Prefrontal Cortical Activation in Patients With Residual Excessive Sleepiness Associated With Obstructive Sleep Apnea/Hypopnea

The primary objective of this study is to determine whether treatment with armodafinil will provide improvements in prefrontal cortical activation in patients with OSAHS (Obstructive Sleep Apnea/Hypopnea Syndrome) who have residual sleepiness despite receiving nCPAP therapy.

Stanford is not currently accepting new patients for this trial. You may want to check to see if other locations are recruiting.
