Anti-N-methyl-D-aspartate receptor encephalitis is a newly described disease process. Patients are generally young females who present with psychiatric symptoms and progress to have seizures, abnormal movements, and. autonomic instability. Diagnosis is made based on serum and cerebrospinal fluid results, However, a characteristic EEG pattern described as extreme delta brush has been associated with this disorder making it especially relevant to neurodiagnostic technologists in practice today. Our case presentations follow two patients through the course of their illness and recovery...

Reported here is the case of a 41-year-old female who developed paranoia and delusions. Physical examination, laboratory studies, and neuroimaging were unremarkable. She was diagnosed with schizophrenia and treated with risperidone, ultimately at a dose of 3 mg daily, with improvement. Her EEG showed bursts of 30-40 Hz gamma activity in the frontal regions, a finding sometimes noted on the resting EEGs of patients with schizophrenia. This report discusses gamma activity as well as other EEG abnormalities that may occur on the resting EEG of patients with schizophrenia...

There exists a paucity of data in the EEG literature on characteristics of "atypical" interictal epileptiform discharges (IEDs), including sharp slow waves (SSWs). This article aims to address the clinical, neurophysiological, and neuropathological significance of SSW The EEGs of 920 patients at a tertiary-care facility were prospectively reviewed over a period of one year. Thirty-six patients had SSWs in their EEG. Of these, 6 patients were excluded because of inadequate clinical data. The clinical and neuroimaging data of the remaining 30 patients were then retrospectively collected and reviewed, and the findings were correlated...

Somatosensory evoked potentials (SSEPs) are a valuable tool for assessing changes in peripheral nerve pathways caused by patient positioning during spinal surgeries. These changes, when left undiagnosed, may lead to postoperative neurological sequelae. Why an upper extremity SSEP attenuates due to positioning is not necessarily clear and can be multifactorial, affecting the peripheral nerves or elements of the brachial plexus. A conduction block can occur at any point along the course of the nerve secondary to entrapment, compression, and ischemia...

The objective of this study was to report on sleep-onset REM period (SOREMP) during routine EEG and conditions associated with it at a comprehensive epilepsy program. We retrospectively reviewed all outpatient and inpatient EEGs performed at Tampa General Hospital, a comprehensive epilepsy center over a four-month period. All EEGs were reviewed by experienced board-certified epileptologists. When SOREMP was identified, the chart was reviewed to identify the most likely etiology and the associated conditions that might be contributing...

Rhythmic midtemporal discharge (RMTD) is a rare, benign EEG pattern that may have epileptic morphology. Recognizing variations of RMTD is important in order to avoid over- or misinterpretation of EEG findings, which may lead to inappropriate treatment and negative consequences for the patient in question. We present a case report of RTMDs during light sleep where initial erroneous description necessitated repeat EEGs and additional diagnostic exams and led to the postponement of obtaining a drivers licence for this young patient...

INTRODUCTION: There is variability in intraoperative neuromonitoring (IONM), anesthetic and surgical techniques for the treatment of pediatric spinal deformity. This study evaluates a series of patients treated at multiple centers utilizing transcranial motor and somatosensory evoked potentials (TcMEP and SSEP) and electromyography (EMG). The frequency of alerts and the intraoperative follow-up is reported. METHODS: Standard patient demographics and IONM data were collected from a two-month cohort of pediatric spine deformity cases...

REVIEW
Nikesh I Ardeshna
Coma is defined as a state of extreme unresponsiveness, in which a person exhibits no voluntary movement or behavior even to painful stimuli. The utilization of EEG for patients in coma has increased dramatically over the last few years. In fact, many institutions have set protocols for continuous EEG (cEEG) monitoring for patients in coma due to potential causes such as subarachnoid hemorrhage or cardiac arrest. Consequently, EEG plays an important role in diagnosis, managenent, and in some cases even prognosis of coma patients...

BACKGROUND: Focal status epilepticus and catastrophic epilepsy are not rare in infants. Epilepsy surgery can be safely done in selected infants to cure epilepsy. PATIENT DESCRIPTION: We report on an infant who began having drug-resistant status epilepticus at 2 weeks of age and developed epileptic spasms. We discuss in detail how the clinical and electroencephalographic data were used to reach a consensus for epilepsy surgery and why a particular surgical approach was preferred over other alternatives...

BACKGROUND: Cortical lesions in status epilepticus have been reported but the underlying mechanisms are poorly elucidated. CASE SUMMARY: We report on afemale patient (75 years) with a history of alcohol abuse who presented with complex partial status epilepticus and lateralized epileptiform discharges in the left frontal and temporal regions in EEG. While cranial magnetic resonance imaging (MRI) showed left hippocampal T2-hyperintensity and diffusion restriction, cerebrospinal fluid was normal and revealed no limbic encephalitis-related antibodies...

We report a case of a child whose EEG demonstrated extreme spindles (ES) after acute lymphoblastic leukemia treatment. This finding has not been reported previously. In 1962, Gibbs and Gibbs described the ES EEG pattern due to its high amplitude (200 to 400 μV). ES are a rare spindle variant that is found in EEGs of 0.05% of normal children (average age, 3 years, with a range of 1 to 12 years), and are even rarer after 11 years. Moreover due to changes in the white matter of the frontal lobe, ES have been associated with such conditions as cerebral palsy and mental retardation, residual brain damage, undefined infections, infantile neuroaxonal dystrophy, Menkes' kinky-hair syndrome, congenital muscular dystrophy, hydrocephalus, porencephaly, epilepsy, progressive cerebellar degeneration, and mycoplasma encephalitis...

PURPOSE: To determine and describe the contribution of Neurodiagnostic (ND) technologists in achieving better patient outcomes. METHODS: An online survey was distributed to ND services leadership (administrators, laboratory managers, supervisors, team leads, service owners, and Medical Directors) in the United States (U.S.) to assess the impact of ND professionals and credentialing on improved patient care. The 9-question internet survey addressed three sections: 1) Participant demographics; 2) Quality improvement with credentialing; 3) Value in obtaining credentials...
