The aim of this study was to investigate, by means of transcranial Doppler ultrasound (TCD), cerebrovascular reactivity during the Valsalva maneuver (VM) during the headache-free interval in patients with migraine (M), migraine plus tension-type headache (M+TTH), and migraine plus medication overuse headache (M+MOH). A total of 114 patients (n=60 M, n=38(More)
Semantic dementia (SD) is a relatively rare primary degenerative brain disease, often with onset before the age of 65, which belongs to the group of frontotemporal lobar degenerations. The central characteristic of SD is a progressive loss of semantic knowledge with manifestation in aphasia as well as impaired face and object recognition. A reliable(More)
The latency and duration of the early (ES 1) and late (ES 2) exteroceptive silent period of temporalis muscle activity were determined in 51 neurological patients. We investigated whether these electrophysiological parameters correlated with neuropsychological variables of the patients using standardized scores for personality index, state of well-being and(More)
Exteroceptive suppression of temporalis muscle activity was proposed by Schoenen and co-workers in 1987 as a tool in headache diagnosis and research. Their finding of a decreased or abolished second silent period (ES2) in chronic tension-type headache sufferers has been confirmed by several independent laboratories during the last five years. Temporalis(More)
Nausea and rigidity of the neck muscles, typical symptoms of post-lumbar puncture syndrome (PPS), may also be found in patients suffering from chronic headache of the tension-type. A decreased duration of the late suppression period of temporal muscle activity indicating a central disturbance of pericranial muscle control, can be observed in these patients.(More)
EMG analysis of the late exteroceptive suppression period of the temporal muscle activity is discussed as comparative methodology in the assessment of patients suffering from chronic tension-type headache and from migraineurs. After electrical perioral trigeminal nerve stimulation during maximum voluntary jaw occlusion, early (ES1) and late (ES2)(More)
In modification of a method published by Schoenen et al., early (ES 1) and late (ES 2) exteroceptive suppression periods elicited by perioral electrical trigeminus-stimulation during teeth-clenching were recorded with surface electrodes over the temporalis muscles. 29 patients with chronic tension headache, 20 with migraine, 7 patients with combined tension(More)
