“…Cognitive testing has been complemented with TCD measures of CBFv to study the executive-function skills (Kral & Brown, 2004;Kral et al, 2003) and language functioning (Sanchez, Schatz, & Roberts, 2010) of children with sickle cell disease; to examine the executive-function deficits, particularly those involved in planning, associated with schizophrenia (Feldmann et al, 2006;Schuepback, Weber, Kawohl, & Hell, 2007); in the attention skills of participants with and without hypotension (Duschek & Schandry, 2004); in elderly adults with versus without depression (Tiemeier et al, 2002); to examine executive functioning in patients with Huntington's disease versus healthy controls (Deckel, Cohen, & Duckrow, 1998); and in the mental activity patterns of healthy individuals versus individuals recovering from stroke versus individuals who have shown no recovery from stroke (Bragoni et al, 2000). The results of these patterns are not as simple as "clinical conditions are associated with slower CBFv"-although that is what one sees for planning by individuals with schizophrenia compared to healthy controls (Feldmann et al, 2006), for depressed individuals compared to their nondepressed cohort (Tiemeier et al, 2002), and for individuals with Huntington's disease compared to healthy individuals (Deckel et al, 1998).…”
