Memory for famous faces can be used to examine the neural systems underlying retrieval from long-term memory. To date, there have been a limited number of functional neuroimaging investigations examining famous face recognition. In this study, we compared recognition of famous faces to recognition of newly learned faces. Whole-brain, event-related(More)
A prevailing neurobiological theory of semantic memory proposes that part of our knowledge about concrete, highly imageable concepts is stored in the form of sensory-motor representations. While this theory predicts differential activation of the semantic system by concrete and abstract words, previous functional imaging studies employing this contrast have(More)
We examined the relationship of age of onset of epilepsy, chronological age at time of operation, and adequacy of preoperative memory performance to pre- to postoperative verbal memory decline. Patients who underwent left (n = 50) or right (n = 51) anterior temporal lobectomy (ATL) were administered tests of verbal episodic (list learning, paragraph recall)(More)
OBJECTIVE To identify the neuropsychological features of the syndrome of mesial temporal lobe epilepsy (MTLE), a surgically remediable epileptic syndrome defined by the presence of hippocampal sclerosis, using a broad and comprehensive neuropsychological test battery. SETTING Epilepsy surgery center. PATIENTS After scalp adn invasive(More)
Neuropsychological and behavioral status were examined in 57 children aged 7 to 16 years with complex partial seizures (CPS) and compared with 27 sibling control children of the same age. Epilepsy had a significant effect on both cognitive and behavioral adjustment measures. Children with CPS had significant impairment across all seven cognitive domains(More)
Conventional memory assessment may fail to identify memory dysfunction characterized by intact recall for a relatively brief period but rapid forgetting thereafter. This study assessed learning and retention after 30-min and 24-hr delays on auditory and visual selective reminding tests (SRTs) in right (n=20) and left (n=22) temporal lobe epilepsy (TLE)(More)
Semantic memory (SM) was investigated in six patients with probable Alzheimer's disease (AD) by on-line measurement of semantic priming in a lexical decision task, and off-line tests of comprehension. Detailed assessment was carried out on naming, name comprehension, and probes of semantic knowledge with a battery of 150 items. The patients performed(More)
OBJECTIVE To determine whether whole-brain, event-related fMRI can distinguish healthy older adults with known Alzheimer disease (AD) risk factors (family history, APOE epsilon4) from controls using a semantic memory task involving discrimination of famous from unfamiliar names. METHODS Sixty-nine cognitively asymptomatic adults were divided into 3 groups(More)
Evidence suggests that physical activity (PA) is associated with the maintenance of cognitive function across the lifespan. In contrast, the apolipoproteinE-ε4 (APOE-ε4) allele, a genetic risk factor for Alzheimer's disease (AD), is associated with impaired cognitive function. The objective of this study was to examine the interactive effects of PA and(More)
PURPOSE To determine the independent effects of depression and anxiety on health-related quality of life (HRQOL) in epilepsy as well as the relative explanatory power of psychiatric comorbidity compared with demographic and clinical epilepsy variables (e.g., seizure frequency, severity, and chronicity). METHODS Subjects (n = 87) with temporal lobe(More)
