High frequency oscillations have been evaluated through a band pass filter between 1 and 20 kHz and centroid luminosity oscillations along x and y axes, CLOx
and CLOy respectively, were obtained.
Green exhibited no sign of cognitive impairment using the Six-Item Screener (score: 6 out of 6) (Callahan, Unverzagt, Hui, Perkins, & Hendrie, 2002) and the Clock Drawing Executive Test (CLOX
) assessment (an executive function clock drawing task) (Shulman, Gold, Cohen, & Zucchero, 1993).

) performance in Alzheimer's disease: a FDG-PET study," Neuroscience, vol.
More fine grained cognitive assessment revealed mild impairment in executive functioning based on the CLOX
(Royall, Cordes, & Polk, 1998) visual spatial performance and delayed recall were severely impaired, based on CERAD subtests (Morris, Heyman, & Mohs, 1989).

B vitamins stabilized executive function (CLOX

However, not all clock drawing tasks are necessarily "executive" and some, such as the Executive Clock Drawing Task (CLOX
), correlate better with other putative executive measures such as the Executive Interview (EXIT25) [29-30].

Several cognitive domains were measured, including speed of processing (Useful Field of View [UFOV] and Complex Reaction Time), psychomotor speed and visuomotor coordination (Trails A, Finger Tapping Test, Digit Symbol Copy, and Digit Symbol Substitution), attention and working memory (Digit Span and Spatial Span), reasoning (Letter Comparison and Pattern Comparison), and executive functioning (Trails B, CLOX
