The nature of the neurocognitive deficits found in obstructive sleep apnea is still debatable. What is the extent of higher executive versus alertness-based cognitive dysfunction? Are cognitive impairments caused by nighttime hypoxemia or daytime sleepiness? This paper demonstrates the importance of a sound theoretical neurocognitive framework to be able to answer these questions. A strategy to...

Alexithymia refers to a cluster of emotion processing weaknesses. Etiological theories suggest frontal lobe impairment, which implicates corresponding executive dysfunction. Although some studies have identified cognitive deficits in alexithymia, no study has systematically investigated executive functioning in this population while simultaneously deconstructing alexithymia and related construc...

Language disorganization is an important clinical indicator of acute psychosis, yet the longitudinal course and pathogenesis are not well understood. Executive dysfunction has been suggested as a vital contributor to formal thought disorder (FTD) and may serve as a stable predictor of symptomatic risk.
