OBJECTIVE To define the clinical and EEG features of the epileptic syndromes occurring in adult and infantile mitochondrial encephalopathies (ME). METHODS Thirty-one patients with recurrent and apparently unprovoked seizures associated with primary ME were included in the study. Diagnosis of ME was based on the recognition of a morphologic, biochemical,(More)
PURPOSE Theory of mind (ToM) is an important prerequisite to social behavior. This study evaluated ToM in patients with temporal (TLE) or frontal lobe epilepsy (FLE) aiming to determine the cognitive aspects, severity, and pathophysiologic mechanisms of ToM impairment in focal epilepsy. METHODS One hundred thirty-eight patients with TLE (n = 109) or FLE(More)
A familial form of Creutzfeldt-Jakob disease (CJD) is linked to the D178N/V129 prion protein (PrP) mutation. Tg(CJD) mice expressing the mouse homolog of this mutant PrP synthesize a misfolded form of the mutant protein, which is aggregated and protease resistant. These mice develop clinical and pathological features reminiscent of CJD, including motor(More)
Semantic memory was evaluated in 124 epilepsy patients, including 84 with left (n=44) or right temporal lobe epilepsy (TLE) (n=40) and 40 with left (n=25) or right frontal lobe epilepsy (FLE) (n=15), in order to determine their verbal and visual deficits, and the neuroanatomical relationships between them. The controls were 35 healthy subjects. Semantic(More)
Rasmussen's encephalitis (RE) is a rare and progressive neurologic condition of uncertain etiology that typically has a childhood onset. The authors describe a 45-year-old woman with adult-onset progressive aphasia, right hemiparesis, severe drug refractory epilepsy, and left cerebral hemisphere atrophy. High-dose corticosteroids and plasmapheresis were not(More)
PURPOSE Periventricular nodular heterotopia (PNH) is among the most common malformations of cortical development, and affected patients are frequently characterized by focal drug-resistant epilepsy. Here we analyzed clinical, MRI, and electrophysiologic findings in 54 PNH patients to reevaluate the classification of PNH, relate the anatomic features to(More)
The aim of this study was to estimate the prevalence and nature of sleep breathing disorders in Myotonic dystrophy type 1 (DM1). We wanted to determine whether there is a relationship between sleep breathing disorders and clinical parameters such as pulmonary function, degree of neuromuscular impairment, daytime sleepiness, and fatigue. This will help(More)
Different point mutations of the mitochondrial genome, which all affect the ability of mitochondria to translate their own genes and lead to partial defects of mtDNA-dependent respiratory complexes, are related to distinct clinical mitochondrial disorders. A new maternally inherited disorder, characterised by a combination of adult-onset myopathy and(More)
The present study included analysis of data from 243 patients surgically treated for Temporal Lobe Epilepsy (TLE). Resection was confined to the temporal lobe, with at least two years of follow-up, and specimens sufficiently preserved to allow a precise evaluation of both lateral neocortex and hippocampus. The frequency of different types of lesion and(More)
OBJECTIVES The purpose of the study was to investigate the abnormalities of cortical lamination observed in temporal lobe specimens obtained during surgery for intractable temporal lobe epilepsy (TLE) with hippocampal sclerosis. Specifically, we aimed to 1) correlate high-field ex vivo MRI with histopathologic analysis and 2) evaluate the effect of tissue(More)
