One issue of continuing debate in language research concerns whether the brain holds separate representations for semantic information through the auditory vs visual modalities. Regardless of whether we hear, see or read meaningful information, our brains automatically activate both auditory and visual semantic associations to the sensory input. The(More)
Mapping eloquent language cortex in presurgical patients typically is accomplished using highly invasive direct cortical stimulation techniques. Functional imaging during language activation using positron emission tomography (PET) is a promising, noninvasive alternative that requires validation. In seven patients undergoing surgical evaluation for(More)
STUDY OBJECTIVES To relate parentally reported sleep concerns in autism spectrum disorders (ASD) to polysomnographic (PSG) findings and measures of daytime behavior and autism symptomatology. DESIGN Cross-sectional study involving validated questionnaires, sleep histories and diaries, 2 nights of PSG, and the Autism Diagnostic Observation Schedule (ADOS).(More)
BACKGROUND Previous reports have documented the coexistence of obstructive sleep apnea (OSA) and epilepsy and the therapeutic effects of treatment on seizure frequency and daytime sleepiness. The authors' objective was to determine the prevalence of OSA and its association with survey items in a group of patients with medically refractory epilepsy(More)
We describe our experience in using melatonin to treat insomnia, a common sleep concern, in children with autism spectrum disorders. One hundred seven children (2-18 years of age) with a confirmed diagnosis of autism spectrum disorders who received melatonin were identified by reviewing the electronic medical records of a single pediatrician. All parents(More)
We used positron emission tomography (PET) with 18F-2-deoxyglucose (FDG) and 15O water in 20 patients with complex partial seizures to compare glucose metabolism and blood flow in temporal lobe epileptic foci identified by ictal scalp-sphenoidal video-EEG telemetry. Glucose metabolism was measured 20 minutes after blood flow without moving the patient from(More)
PURPOSE To test the hypothesis that deepening sleep activates focal interictal epileptiform discharges (IEDs), we performed EEG-polysomnography in 21 subjects with medically refractory temporal lobe epilepsy. METHODS At the time of study, subjects were seizure-free for > or =24 h and were taking stable doses of antiepileptic medications (AEDs). Sleep(More)
Sleep difficulties in children with autism spectrum disorders are common, with poor sleep hygiene a contributing factor. We developed the Family Inventory of Sleep Habits to measure sleep hygiene in this population. Its validity and reliability in 2 groups of children aged 4 to 10 years, those with a clinical diagnosis of autism spectrum disorders, and(More)
PURPOSE Epilepsy surgery can result in complete seizure remission rates of upto 80% in patients with mesial temporal sclerosis and unilateral seizures. The seizure-free rate after surgery for patients with extratemporal nonlesional epilepsy has ranged between 30% and 40%. Some patients with medically refractory localization-related epilepsy cannot be(More)
Supplemental melatonin has shown promise in treating sleep onset insomnia in children with autism spectrum disorders (ASD). Twenty-four children, free of psychotropic medications, completed an open-label dose-escalation study to assess dose-response, tolerability, safety, feasibility of collecting actigraphy data, and ability of outcome measures to detect(More)
