This is a retrospective case series of pediatric patients referred to the psychogenic nonepileptic events clinic (PNEE) who had comorbid diagnoses of autism spectrum disorder (ASD) or intellectual disability (ID). We describe 15 patients, nine with ASD and six with ID who had a telephone visit follow-up at 12 months. There were higher rates of…

To assess the role of clinical features in diagnosing seizures in children with autism spectrum disorder who present with staring spells. A 10-year retrospective chart analysis of autism spectrum disorder patients aged 3-14 years was performed at a tertiary care children's hospital. Patient demographics, clinical presentation, and epileptic…

This study examined hospitalizations in a large, all-payer, nationally representative sample of inpatient hospitalizations in the US and identified differences in rates of hospitalization for conditions by race and ethnicity in autistic adults. Conditions examined included mood disorders, epilepsy, schizophrenia, and ambulatory care sensitive…

The clinical similarity among different neuropsychiatric disorders (NPDs) suggested a shared genetic basis. We catalogued 23,109 coding de novo mutations (DNMs) from 6511 patients with autism spectrum disorder (ASD), 4,293 undiagnosed developmental disorder (UDD), 933 epileptic encephalopathy (EE), 1022 intellectual disability (ID), 1094…

Background: People with epilepsy (PWE) have a higher fracture risk than nonepilepsy populations. Antiepileptic drugs (AEDs) cause bone loss. Limited physical activity and poor dietary intake increase fracture risk in PWE. People with an intellectual disability have higher prevalence of epilepsy, likely to be on multiple AEDs, with poorer response,…

Background: It is well established that valproate, and its valproic acid, sodium valproate, and valproate semisodium forms is a highly teratogenic drug and evidence suggests that use in pregnancy leads to physical birth defects in 10% of children born compared with a background rate of 2% to 3%. Congenital malformations associated with valproate…

Mixed Group Validation (MGV) is an approach for estimating the diagnostic accuracy of tests. MGV is a promising alternative to the more commonly used Known Groups Validation (KGV) approach for estimating diagnostic accuracy. The advantage of MGV lies in the fact that the approach does not require a perfect external validity criterion or gold…

Data from 1,261 Chinese Autistic Spectrum Disorder (ASD) patients were evaluated and categorized into dysmorphic (10.79%) and non-dysmorphic groups (89.21%) upon physical examination by the presence of dysmorphic features. Abnormal MRI/CT result, IQ scores and epilepsy were significantly associated with the dysmorphic group of ASD children.…

Severe myoclonic epilepsy of infancy (SMEI) is a complex form of epilepsy that was first described in France in 1978. Because the myoclonic component of this epilepsy is not always present and because some variability has been observed in the symptomatology, the name was changed to Dravet syndrome in 1989. The genetic aetiology of this epilepsy…

We applied near-infrared spectroscopy (NIRS) and electrocorticography (ECoG) recordings during cortical stimulation to a temporal lobe epilepsy patient who underwent subdural electrode implantation. Using NIRS, changes in blood concentrations of oxyhemoglobin (HbO[subscript 2]) and deoxyhemoglobin (HbR) during cortical stimulation of the left…

Given the grave morbidity and mortality of drug-resistant epilepsy, it is of great clinical interest to determine how often prior proven drug-resistant epilepsy is reversible without surgery and whether remission can be predicted by clinical features in children with incident drug-resistant epilepsy. We determined the likelihood of 1-, 2- and…

We present two phenotypically similar females with Xp duplication who have autism and epilepsy. Case 1 is a 14-year-old Honduran female with autism and medically refractory complex partial, secondarily generalized epilepsy. Case 2 is a 3-year-old Austrian female with autism and medically refractory complex partial epilepsy. Both patients also…

In deja vu, a phenomenological impression of familiarity for the current visual environment is experienced with a sense that it should in fact not feel familiar. The fleeting nature of this phenomenon in daily life, and the difficulty in developing experimental paradigms to elicit it, has hindered progress in understanding deja vu. Some…

Before performing neurosurgery, an exhaustive presurgical assessment is required, usually including an investigation of language cerebral lateralization. Among the available procedures, the intracarotid amobarbital test (IAT) was formerly the most widely used. However, this procedure has many limitations: it is invasive and potentially traumatic,…

Patients with temporal-lobe epilepsy (TLE) present with memory difficulties. The aim of the current study was to determine to what extent these difficulties could be related to a metamemory impairment. Fifteen patients with TLE and 15 matched healthy controls carried out a paired-associates learning task. Memory recall was measured at intervals of…
