Cortical reflex myoclonus in Rett syndrome.
Rett syndrome (RS) is one of the most frequent causes of mental retardation in females. As there are no known biochemical, genetic, or morphological markers, diagnosis is based on clinical phenotype including severe dementia, autism, truncal ataxia/apraxia, loss of purposeful hand movements, breathing abnormalities, stereotypies, seizures, and extrapyramidal signs. Myoclonus, although reported ...
متن کاملFocal reflex myoclonus.
In a patient with reflex myoclonus limited to the right side of the body, stimulation of the right median nerve in the index finger or wrist elicited a very large somatosensory evoked response (SER) and a long loop C reflex which represents an electrically evoked myoclonic response. It is suggested that the pathway for the C reflex is through peripheral nerve, dorsal funiculus of spinal cord, c...
متن کاملA case of cortical tremor as a variant of cortical reflex myoclonus.
Myoclonus sometimes represents rhythmical movement and cortical tremor has been defined as a rhythmical movement accompanied by cortical reflex myoclonus [1]. We examined a patient with cortical tremor who demonstrated rhythmical muscle discharges evoked by a peripheral nerve stimulation. A 64-year-old man had a 9-year history of postural tremor involving the hands and fingers. The patient also...
متن کاملReflex myoclonus in olivopontocerebellar atrophy.
The presence of reflex myoclonus in response to touching and pin-pricking the wrist or stretching the fingers and to photic stimulation was assessed in 24 patients with a presumed diagnosis of olivopontocerebellar atrophy (OPCA) and in 30 age matched control subjects. Reflex myoclonus to soma-esthetic stimulation was found in 23 patients and in none of the controls. Photic myoclonus was present...
متن کاملUraemic myoclonus: an example of reticular reflex myoclonus?
Two patients are described who developed action, reflex myoclonus during acute renal failure. In both cases the myoclonus was abolished after the intravenous administration of clonazepam. We suggest that the characteristic action myoclonus, which occurs in both acute renal failure and postanoxic encephalopathy, is caused by a disturbance of function in the lower brainstem reticular formation.
