An electrophysiological study of the blink reflex was undertaken in 25 control subjects and in 57 patients with Parkinson's disease. An increase in the ipsilateral and contralateral late response was the most evident finding. The excitability cycle of recovery of the R2 component of the blink reflex after a prior conditioning shock was enhanced in the(More)
An electrophysiological study of the blink Reflex was undertaken in 40 dyskinetic and 20 nondyskinetic patients with Parkinson's disease, who were matched for age, stage of disease, duration of illness and amount and nature of antiparkinsonian medication. We found that latencies of R2 responses (both ipsilateral and contralateral) were prolonged in the(More)
A patient developed weakness in the upper limbs, eventually causing brachial diplegia with only slight paresis of the legs after rapid correction of severe hyponatraemia. Pseudobulbar palsy, mental confusion and urinary incontinence were also present. CT scan showed a zone of lucency in the pons. Clinical recovery occurred and the zone of lucency had(More)
We have studied the electrically evoked blink reflex (R1 and R2 components) in 40 parkinsonian patients with levodopa-induced dyskinesia (15 with facial dyskinesia, 13 with limb-truncal dyskinesia and 12 with mixed dyskinesia). R2 latencies (both ipsilateral and contralateral) were significantly prolonged in dyskinetic patients. These findings are(More)
