PURPOSE Standard polysomnography (PSG) typically utilizes 4-6 channels of electroencephalography (EEG), which is inadequate to evaluate focal epileptiform activity. Though technical capability has long existed for more extensive EEG recording, few sleep laboratories have utilized this technique. The objective of this study was to determine the utility of combining PSG with 18-channel EEG in sel...

OBJECTIVE To provide a comprehensive description of abnormal behaviors in patients with Gaucher disease type 3 (GD3) and relate these behaviors to demographic, neurodevelopmental, and neurologic characteristics. METHODS Thirty-four Egyptian patients with GD3 (mean age of 7.9 years) were enrolled in the study. They were selected based on parent report and/or physician observation of one or mor...

This EEG Guideline incorporates the practice of structuring a report of results obtained during routine adult electroencephalography. It is intended to reflect one of the current practices in reporting an EEG and serves as a revision of the previous guideline entitled "Writing an EEG Report." The goal of this guideline is not only to convey clinically relevant information, but also to improve in...

PURPOSE EEG interpretation is a fundamental procedural skill in the practice of neurology, but there is no standardized method for educating residents. One-to-one instruction is commonly employed, but is time intensive for supervising physicians, provides arbitrary exposure to normal and abnormal EEG patterns, and often lacks immediate and detailed feedback on performance. Here, we investigated...

PURPOSE To study the usefulness of EEG in the diagnosis of lissencephaly, a rare cortical developmental disorder associated with abnormal cellular proliferation. Currently, the clinical emphasis is placed on the radiological and genetic aspects for the diagnosis of lissencephaly. METHODS This is a retrospective review of consecutive EEG recordings and imaging data from 14 children, with the d...

We evaluated whether abnormal frequency composition of the resting state electroencephalogram (EEG) in schizophrenia was associated with genetic liability for the disorder by studying first-degree biological relatives of schizophrenia patients. The study included a data-driven method for defining EEG frequency components and determined the specificity of resting state EEG frequency abnormalitie...

Electroencephalography (EEG) is a sensitive method for detection of brain injury in preterm infants. Although the acute and chronic EEG changes are mainly non-specific regarding type of injury, they correlate with later neurological and cognitive function. In infants developing periventricular hemorrhagic or ischemic brain injury, acute EEG findings include depression of background activity and...

THIP (Gaboxadol) is a selective GABA A agonist, acting in vitro with high potency and efficacy at the extrasynaptic GABA A containing receptors. THIP was suggested to be a potential hypnotic to treat insomnia and it is currently in clinical trial. Here we assessed whether the GABA A -containing receptors mediate in vivo the effect of THIP on sleep and the sleep electroencephalogram (EEG). We...

Transient epileptic amnesia (TEA) is defined as recurrent ictal and interictal transient memory disturbances typically occurring upon waking. Patients with TEA usually cannot remember the episodes. Electroencephalographic (EEG) abnormalities are usually localized on the dominant or bilateral temporal lobes. Here we report two cases of TEA with atypical features. The patients could remember the ...
