Vaughn explained that reading an EEG involves pattern recognition. The EEG signal does not come from individual brain cells nor the axons of those cells, but from a summation of the signals of many neurons. However, the waves on the EEG have no relationship to the synaptic potential of the cell body. There are many synapses, and the summation gives us the EEG. The brainвЂ™s neurons are similarly oriented in the cortex. Vaughn described the term epileptogenic as a descriptor of brain electrical discharges that appear to be the start of a seizure, with interictal discharges being those that occur between seizures. Although the EEG aids the clinician enormously, Vaughn noted the diagnostic limitations of EEG techniques, and so other clinical clues are often used to confirm the diagnosis. In sleep-deprived patients with epilepsy, the percentage of patients with observable discharges associated with epilepsy climbs to 80%. About 2% of the general population experiences epileptiform discharges in the absence of seizure disorder. An estimated 1% of the population has epilepsy, but only 60% of those people have epileptiform discharges. Seizures include any sudden morbidity event, either sensory or motor, and epileptic seizures include pathologic, synchronous neuronal firing. Vaughn proceeded to outline electroencephalogram (EEG) readings, interictal discharges, and possible pitfalls in identifying interictal discharges.Д¬ontinuing, Vaughn described epilepsy as a group of disorders characterized by recurrent epileptic seizures. He polled the audience about how easily epileptiform discharges were identified, and very few audience members indicated complete comfort in identifying these phenomena. Vaughn noted a cluster of features observed in patients with epilepsy and provided the audience a glimpse into how video polysomnography may help to identify seizures. Vaughn, MD, vice chair of neurology and the chief of the division of sleep and epilepsy at the University of North Carolina School of Medicine, discussed epileptiform activity in ictal and interictal discharges. This is used to monitor the effectiveness of a treatment.Bradley V. Maintenance wakefulness test вЂ“ For this test, your child will remain at ChildrenвЂ™s the day after an overnight study, but will stay awake all day.Your child will take 20-minute naps every two hours during the day. This test is typically used for children suspected of having narcolepsy or hypersomnia (excessive daytime sleepiness). It allows doctors to determine how tired a child is the next day. Multiple sleep latency test (MSLT) вЂ“ This test is taken the day after an overnight sleep study.A staff member will explain what will be done before and while sensors are being placed on your child. Your childвЂ™s oxygen levels and breathing will also be monitored. There is no pain involved in the placing of these sensors. The test is done with sensors which are secured with gel and placed on your childвЂ™s head, chin, legs, chest and near the eyes. Polysomnogram вЂ“ This is an overnight test which records different sleep stages, and monitors your child during the night for signs of various sleep disorders.There are several different types of sleep studies including: Resources for Transgender Youth and Their FamiliesДЄ sleep study is used to diagnose sleep disorders.Pediatric Clinical Trials & Experimental Medication.Child Life and Music Therapy Training Opportunities.Fellowship and Subspecialty Training Programs.ChildrenвЂ™s Health is proud to become the first pediatric health system in the country to offer Amazon Lockers, self-service kiosks that allow you to pick up your Amazon packages when and where you need them most вЂ“ 24 hours a day, seven days a week.
