Comparison of Parametric and Non-parametric EEG Feature Extraction Methods in Detection of Pediatric Migraine without Aura
Background: Migraine headache without aura is the most common type of migraine especially among pediatric patients. It has always been a great challenge of migraine diagnosis using quantitative electroencephalography measurements through feature classification. It has been proven that different feature extraction and classification methods vary in terms of performance regarding detection and di...

Abstract Background: Dysfunction of the autonomic nervous system has long been a subject of considerable debate and a large number of studies have disclosed contradictory results. The aim of this study was to compare cerebral vasomotor reactivity in migraine with aura (MWA) patients with migraine without aura (MWO) ones. Methods: Ten MWA patients (7 females and 3 males mean age: 39.70 years, S...

Introduction & Objective: Mechanisms underlying migraine precipitation are largely unknown. Helicobacter pylori (H. pylori) infection has recently been associated with various extraintestinal pathologies and migraine. The relation between Helicobacter pylori and Migraine is controversial. The aim of this study was to investigate the correlation of the H. pylori infection with migraine. Materi...
متن کاملAbnormalitites of Visual Evoked Potential in Migraine Patients
Background: Visual evoked potential (VEP) is regarded as a useful, reliable and non-invasive technique for the diagnosis of lesions in the optic pathway. This technique was used to investigate visual function in migraine. Materials and Methods: 53 migraine patients (27 migraine cases with aura and 26 common migraine cases) and 55 controls were prospectively enrolled in this study. Visual ev...
متن کاملMigraine aura and related phenomena: beyond scotomata and scintillations.
Migraine affects the cortical physiology and may induce dysfunction both ictally and interictally. Although visual symptoms predominate during aura, other contiguous cortical areas related to less impressive symptoms are also impaired in migraine. Answers from 72.2% migraine with aura and 48.6% of migraine without aura patients on human faces and objects recognition, colour perception, proper n...
