Transcranial magnetic stimulation measured cortical inhibition provides insight into interindividual differences in progressive myoclonic epilepsy

A new study has found that abnormality of intracortical inhibition in patients with progressive myoclonic epilepsy type 1 is associated with the magnitude of genetic change. The results suggest that transcranial magnetic stimulation could be useful in assessing patient prognosis and may have use as a marker of GABAergic impairment.
