The first electro encephalo graphy (EEG) on a human was reported by Hans Berger in 1920. The fundamental principle of EEG is to record the electrical activity produced by the brain, using electrodes. In considering the role of EEG in psychiatry almost 25 years later, Dennis Williams (1954) observed that studies of EEG recordings had offered the clinical psychiatrist little of positive value. He...

OBJECTIVES The objectives of this study were to delineate the etiologic profile and neurodevelopmental outcome of neonatal seizures in the current era of neonatal intensive care and to identify predictors of neurodevelopmental outcome in survivors. METHODS Eighty-nine term infants with clinical neonatal seizures underwent neurologic examination, electroencephalography (EEG), neuroimaging, and...

Hemiplegic migraine (HM) is an uncommon type of migraine which is classified into sporadic and familial subtype. The noticed electroencephalogram (EEG) findings during HM attack are diffuse slowing contralateral to the weakened limb, but are usually normal in asymptomatic states. A 52-year-old woman who suffered from headache accompanying right arm weakness and aphasic symptoms admitted to our ...

Electrical activity of each brain region is homeostatically regulated, resulting in predictable frequency composition of the background EEG. Replicated normative databases have established that the EEG power spectrum is independent of ethnic background. Artifact-free EEG evaluated relative to such norms displays few deviant values in healthy, normally functioning individuals. In subjects with p...

Previous techniques for seizure detection in newborn are inefficient. The main reason for their relative poor performance resides in their assumption of stationarity of the EEG. To remedy this problem, we use time-frequency distributions (TFD) to analyse and characterise the newborn EEG seizure patterns as a first step toward a time-frequency (TF) based seizure detection and classification sche...

A prevalence study of epilepsy in patients with Down syndrome (n = 85) in three age-groups (14-16 years, 23-29 years, 50-60 years) was conducted in the county of Aarhus, Denmark. Seventy-two patients (85%) participated. An interview and a neurological examination were performed. An EEG was recorded in 50 patients. Twelve patients (17%) had epilepsy. ILAE-1981-classification: two with partial se...

56 Y/O woman diagnosed with Alzheimer’s Disease and has been in a nursing home, and wheel chair bound, for 4 years. She stopped eating and was brought to the County Psychiatric Center ER. She was admitted to the Neuropsychiatry ward. In reviewing her history a complete work up was never performed. A comprehensive evaluation was started including blood work,CT and EEG. There was nothing signific...

Brain-related disorders such as epilepsy can be diagnosed by analyzing electroencephalograms (EEG). However, manual analysis of EEG data requires highly trained clinicians, and is a procedure that is known to have relatively low interrater agreement (IRA). Moreover, the volume of the data and the rate at which new data becomes available make manual interpretation a time-consuming, resource-hung...
