Using cluster analysis Libon et al. (2010) found three verbal serial list-learning profiles involving delay memory test performance in patients with mild cognitive impairment (MCI). Amnesic MCI (aMCI) patients presented with low scores on delay free recall and recognition tests; mixed MCI (mxMCI) patients scored higher on recognition compared to delay free(More)
Throughout the 1990s a variety of schemes for the diagnosis of Vascular Dementia (VaD) were proposed, including the ADDTC criteria for Ischemic Vascular Dementia, the NINDS-AIREN criteria for Vascular Dementia, Bennett's criteria for Binswanger's disease, and the ICD-10 criteria for Vascular Dementia. We undertook a retrospective analysis of a series of(More)
A group of 94 nondemented patients self-referred to an outpatient memory clinic for memory difficulties were studied to determine the incidence of single versus multi-domain mild cognitive impairment (MCI) using Petersen criteria. Fifty-five community dwelling normal controls (NC) participants without memory complaints also were recruited. Tests assessing(More)
The introduction of diagnostic criteria for vascular dementia has helped to re-define the impact of various subcortical neuropathologies on aging; however, state-of-the-art neuroimaging techniques and autopsy studies suggest that not all structural brain alterations associated with vascular dementia are exclusive to this neurodegenerative process alone.(More)
Differential patterns of executive function deficits (EFD) exist in cortical and subcortical dementia; however, little work exists attempting to integrate these findings into a conceptual framework. The current study aimed to characterize EFD in cortical and subcortical dementia. Patients with Alzheimer's disease (AD; n = 65), subcortical ischemic vascular(More)
BACKGROUND Epidemiologic autopsy studies show mixed Alzheimer's disease (AD)/vascular pathology in many patients. Moreover, clinical research shows that it is not uncommon for AD and vascular dementia (VaD) patients to be equally impaired on memory, executive, or other neurocognitive tests. However, this clinical heterogeneity has not been incorporated into(More)
Libon et al. (2010) provided evidence for three statistically determined clusters of patients with mild cognitive impairment (MCI): amnesic (aMCI), dysexecutive (dMCI), and mixed (mxMCI). The current study further examined dysexecutive impairment in MCI using the framework of Fuster's (1997) derailed temporal gradients, that is, declining performance on(More)
Tissue expanders have been used in multiple body sites. We successfully used the Radovan tissue expander in the scalp of patients with cicatricial alopecia and in hair replacement surgery for male pattern alopecia. The expander is placed in the subgaleal plane beneath a hairbearing area and is inflated over a six- to eight-week period. In a second(More)
BACKGROUND Digital Clock Drawing Test (dCDT) technology enables the examination of detailed neurocognitive behavior as behavior unfolds in in real time; a capability that cannot be obtained using a traditional pen and paper testing format. OBJECTIVE Parameters obtained from the dCDT were used to investigate neurocognitive constructs related to(More)
