Ictal single photon emission computed tomographic study of myoclonic absence seizures

Using SPECT, we showed that, in addition to the thalamus and basal ganglia, the perirolandic cortical motor area is involved in MAs. We hypothesize that in MAs the blood perfusion in the perirolandic cortical motor area might have changed under the influence of the cortico-thalamic network oscillation features. The CBF properties observed by means of our SPECT procedure may represent key features of the pathophysiological mechanisms underlying MAs.
