Abstract
The authors compared stretch-evoked somatosensory evoked potentials (SEP) of 18 type 3 Gaucher disease (GD3) patients (two with progressive myoclonus epilepsy [PME]) with 22 age-matched normal controls and six patients with type 1 (nonneuronopathic) Gaucher disease (GD1). The mean P1-N2 SEP amplitude in GD3 patients was significantly larger than the SEP in controls and in GD1 patients, and there was a significant negative correlation between SEP amplitude and the IQ of GD3 patients. The authors conclude that abnormal cortical inhibition is a unifying feature of GD3 patients and correlates with the degree of cognitive deficit.
