“…This is important because there has been a certain amount of controversy with regard to how well one can identify hemisphere ofepileptic focus by observing memory performance in presurgery patients (Andrewes, Puce, & Bladin, 1990;Delaney, Rosen, Mattson, & Novelly, 1980;Mungas, Ehlers, Walton, & McCutchen, 1985). In this small group of subjects, at least, the tests employed in Experiments 1 and 2 appear to fare quite wen in this regard.…”

Dissociations among memory measures in memory-impaired subjects: Evidence for a processing account of memory

Deficits in conceptual transfer on both implicit and explicit memory tests were obtained for memory-impaired temporal lobe epileptic (TLE) subjects in three studies. In Experiment 1, in which a generate-read paradigm was employed, memory-impaired TLEs failed to show normal generation effects on conceptually driven tests of semantic cued recall and general knowledge questions, although their data-driven memory as measured by word-fragment completion and graphemic cued recall tasks was normal. In Experiment 2, memory-impaired patients having left temporal lobe seizure foci were tested on these four tasks and compared with nonimpaired TLEs having right temporal foci. The left TLEs showed deficits on conceptually driven tasks and normal memory for data-driven tests. These findings were extended in Experiment 3, in which left TLE patients failed to show any benefit from blocked study, as compared with random study, on category production and semantic cued-recall tests, although right TLEs and normal controls showed blocking effects on both tasks. These findings may be accommodated by a processing framework of memory in which memory-impaired patients are characterized as having deficits in conceptual, but not in data-driven, processing capabilities.

“…This difficulty is probably related to the hippocampus region or it might be directly related to the proximity of the focus for primary areas and associated cortex. [25][26][27] No studies dealing with psychoacoustic audiometric tests within auditory processing evaluation of epileptic patients were found in the literature. All the studies involving the auditory processing of epileptic patients were performed using auditory evoked responses.…”

Staggered spondaic word test in epileptic patients

CONTEXT: Auditory processing during childhood may be altered if there is any predisposing factor during the course of development. Neurological disorders are among the risk factors for auditory processing impairment. From this perspective, epileptic children present such a risk factor and could present auditory processing dysfunction. OBJECTIVE: To evaluate central auditory processing in epileptic patients using the Staggered Spondaic Word Test (SSW) in order to verify whether these patients presented auditory disorders and whether the type of crisis partial or generalized played a role in the occurrence and type of disorder. SETTING: Tertiary care hospital. SAMPLE: Thirty-eight children and adolescents, ranging from 7 to 16 years old, with a diagnosis of epilepsy divided into two groups: 23 patients with partial crisis and 15 patients with generalized crisis. MAIN MEASUREMENTS: Performance in the Staggered Spondaic Word Test versus epileptic crisis type (partial or generalized). RESULTS: The majority of epileptic patients showed central auditory processing disorders. There were no differences in relation to crisis type. Both groups showed similar performance, although the results observed for these patients differ from what is obtained with normal populations. With regard to response bias, there were also no differences in performance between subjects with partial or generalized seizures. All possible disorders were found in both groups, without the prevalence of one specific disorder over the other. CONCLUSIONS: This study revealed a high prevalence of disorders among epileptic patients in relation to processing partially overlapped verbal sounds in a dichotic paradigm.

The usefulness of trontal lobe (FL) dysfunction as a conceptual model for Attention Deficit Hyperactivity Disorder (ADHD) was investigated.Twenty-four ADHD and 24 normal control (Ne) children were tested using tasks sensitive to FL deficits in motor control and problem solving skills and memory tasks sensitive to temporal lobe (TL) Venis Raymond for translatlng the abstract into French, and ta the many triends and colleagues who kept me going. l especially thank Ur.
