To determine the possible electrophysiologic changes in migraineurs with or without visual aura, we investigated pattern-reversal visual evoked potentials in 39 patients. We compared the mean P100 latency and amplitude of 16 patients with aura, 23 patients without aura, and 17 age- and sex-matched normal subjects. There were no significant differences(More)
OBJECTIVES Sudomotor efferent nerve fiber function was studied in carpal tunnel syndrome (CTS). METHODS Bilateral median and ulnar sympathetic skin response (SSR) were recorded by sternal stimulation in 22 bilateral and 9 unilateral patients and compared with 21 healthy volunteers. RESULTS There was no significant difference between median and ulnar(More)
Standing with the thigh extended or lying still provokes and stepping or sitting relieves the symptoms in some patients with meralgia paresthetica. We performed this study to confirm this clinical feature with electrophysiological measures. Twenty-one symptomatic and 17 asymptomatic legs of 19 patients were evaluated by somatosensory evoked potential(More)
Although cortical inhibition deficit has been shown in schizophrenia patients by transcranial magnetic stimulation (TMS), some controversies remain, possibly due to confounding factors such as medication use and clinical state at the time of assessment. First-degree relatives of schizophrenia patients, who share various degrees of genetic vulnerability with(More)
A total of 18 patients with Parkinson's disease were evaluated clinically and by transient checker-board VEP study. There were significant differences between bradykinesia (P<0.01), rigidity (P<0.02), and tremor (P<0.05) subscores of the more and less severely affected sides. There were no asymmetry of VEP latency or amplitude between the more and less(More)
Intravenous immunoglobulin (IVIg) treatment for acute exacerbations of Myasthenia Gravis (MG) was shown in several open-label studies. There are only two studies demonstrating the efficiency of regular intermittent IVIg therapy on MG patients who are not in their acute attack periods. Thirteen patients who had displayed an inadequate clinical response to(More)
To examine if the effect of temperature on neuromuscular jitter differs in myasthenics and normals, we performed single fiber electromyography (SFEMG) in 10 myasthenics and 10 healthy controls after heating the upper extremity to 37 and 42 degrees C. In each case, 10-24 mean consecutive difference (jitter) values were obtained at both temperatures. All(More)
We investigated the severity and the quality of pain in the end-plate and the electrically silent site during electromyography by self-assessment. In 42 muscles of 30 patients, the mean pain score was 52.0 +/- 5.3 of 100 for the end-plate region, and it was 27.7 +/- 4.8 for the silent site. The commonest type of pain was pricking both in the end-plate(More)
A fifty-two year old postmenopausal woman was admitted to the hospital with complaints of diplopia, headache, humming over the head, and pain over the left eye. Neurological examination showed right abducens nerve palsy. In a few days, she also developed left abducens nerve palsy and chemosis, exophthalmos, and proptosis of both eyes. There was pulsation(More)
