Material-specific memory in the intracarotid amobarbital procedure
Perrine K; Gershengorn J; Brown ER; Choi IS; Luciano DJ; Devinsky O
We examined material-specific memory in 45 left hemisphere language dominant patients with temporal complex partial seizures (24 right, 21 left) during the intracarotid amobarbital procedure (IAP) by showing eight cards displaying two line drawings of common objects, two printed words, one colored shape, one math expression, one face, and one abstract shape following amobarbital injection (mean = 109.9 mg). We assessed delayed recall and recognition following clearing. Patients with right foci recognized significantly fewer verbally mediated stimuli (words, object drawings, colored shape) with left than with right injection. Patients with left foci recognized a nonverbal stimulus (abstract shape) more poorly following right versus left injection. Discriminant function analysis lateralized 85% of the sample from memory predictors, upheld to 81% on crossvalidation. Material-specific memory remains intact in the hemisphere contralateral to a seizure focus, but wider representation may occur for stimuli normally dominant for the hemisphere with the seizure focus. The IAP significantly lateralizes a seizure focus with use of both types of stimuli

Nonepileptic seizures during apparent sleep
Thacker K; Devinsky O; Perrine K; Alper K; Luciano D
We report 12 patients with nonepileptic seizures (NESs) documented with video-electroencephalographic monitoring during apparent sleep. There were 7 females and 5 males, ages 11 to 67 years (mean, 33 yr). In all patients there was a well-organized posterior alpha rhythm present immediately before onset of clinical changes despite the appearance of sleep. Patients later 'confirmed' that these attacks occurred during sleep. Features of these episodes were typical of NESs and none were associated with ictal or postictal electroencephalographic changes other than muscle and movement artifact. Provocative testing with suggestion confirmed the nonepileptic nature of these episodes in 9 patients. Three patients had epileptiform discharges during prolonged interictal recordings and 1 had a documented complex partial seizure. Our findings indicate that reports of seizures during sleep are not uncommon among patients with NESs

Ictal and postictal apraxia
Devinsky O; Vazquez B; Perrine K; Luciano DJ
Presents the cases of 2 right-handed patients (a 62-yr-old man and a 24-yr-old woman) with ictal and postictal apraxia. The Ss were unable to perform previously learned motor tasks either during or after a partial seizure arising in the left temporal region with rapid spread to the left frontoparietal areas. The Ss were able to recall and clearly describe the apraxic nature of their deficit. These cases are consistent with an apraxia resulting from inhibition of dominant hemisphere association cortex subserving complex motor acts.
