The total sample consisted of 607 children with ADHD from the only center diagnosing and treating ADHD in the region. EEGs were obtained in 517 cases, and EAs were found in 39(More)
BACKGROUND The purpose of this study was to investigate to what extent sleep deprivation provokes epileptiform discharges in EEG in patients with suspected epilepsy. MATERIAL AND METHODS Data from 189 adults and children with unspecified seizures who had had EEG after sleep deprivation were evaluated retrospectively. Previous standard EEGs were without(More)
PURPOSE The knowledge about possible relationships between ADHD and epilepsy is largely based on small samples of ADHD patients and on cohorts with epilepsy. There is insufficient information about the clinical characteristics of epilepsy among children diagnosed with ADHD. The aim of this study was to investigate the prevalence and characteristics of(More)
BACKGROUND Neurological manifestations appear to be frequently involved in patients with primary Sjögren syndrome (PSS).

PURPOSE This study investigated whether interictal epileptiform discharges (IED) on a baseline routine EEG in children with ADHD was associated with the occurrence of epileptic seizures (Sz) or influenced the use of methylphenidate (MPH) during 2 years follow-up. METHODS A retrospective chart-review of 517 ADHD children with EEG revealed IED in 39 cases.(More)
BACKGROUND Electroencephalography (EEG) is used for studying functional disorders of the brain. We provide an overview of the areas where EEG is most strongly indicated and the clinical benefit of the examination. METHOD This article is based on articles from personal literature archives and literature searches in PubMed, textbook on methods in clinical(More)
BACKGROUND Many children with ADHD develop epilepsy, and approximately 20% of children with epilepsy also have ADHD. In this article we discuss the use of EEG in connection with ADHD in children, with emphasis on the diagnosis of comorbid epilepsy. METHOD The article is based on a literature search in PubMed, personal literature archives and the authors'(More)
