Specifically, tasks drawing upon executive processes would predict frontal WMH, while memory measures would predict temporal white matter lesions.
Most patients had multiple psychometric tests, including the Clinical Dementia Rating, the Dementia Rating Scale-Second Edition (DRS-2), the MMSE, and tests of frontal executive function, memory, language, praxis, visuospatial construction, motor performance, mood and function.
Generally speaking, activation in the inferior frontal gyrus during memory tasks appears to be lateralized to the left (Broca's area) and to be associated with subvocal speech approaches to the tasks (for a review, see Fletcher and Henson 2001).
Examination of cerebral blood flow changes associated with pitch naming minus baseline in the AP automatic template group confirmed the same significant activation peak in the posterior extent of the left superior temporal gyrus (−61, −31, 5) with no associated changes in right frontal pitch working memory structures.
Together, these results illustrate differences in inter-regional connectivity and a distinct spatial pattern of network recruitment in schizophrenia within this key frontal-parietal working memory network, thereby providing further evidence for a "disconnection hypothesis" [18] of schizophrenia.
In particular, our results revealed lower scores in the subscales assessing verbal memory, attention, frontal and visuospatial functions, in line with several previous studies [8 15].
In 2002, she contributed to a study on memory called "Frontal lobe activation during object permanence: data from near-infrared spectroscopy" during her psychology studies at Harvard.
We did not observe a significant group difference of frontal activation in false memory trials (Fig. 3c).
They concluded that IADL requiring memory or frontal cortex executive functioning are at particular risk of decline in MCI.
PET analyses showed hypometabolism in the left parietotemporal area and neuropsychometric testing indicated deficits in language, frontal function and preserved memory.
