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.
