Perfusion abnormalities are a major cause of epileptic discharge, and the existence of abnormal perfusion loci implies possible relapse. Very little is known about perfusion abnormality repair in epilepsy. The present study selected 43 cases of idiopathic epilepsy under antiepileptic drug control for an average of 24 months. Comparisons between interictal single-photon emission CT （SPECT） images and long-term electroencephalogram （EEG） pre- and post-treatment showed that cases of normal SPECT increased by 48% （12/25） following treatment, with a total number of 15 reduced loci （,36%, 15/41 ）. Perfusion foci, Le., region of interest, were altered following treatment. These changes included： normal to abnormal in 3 cases （7%, 3/43; 2 hyperperfusion and 1 hypoperfusion）; abnormal to normal in 14 cases （32%, 14/43; 10 pre-treatment hypopeffusion and 4 hyperperfusion）; abnormal to abnormal in 7 cases （16%, 7/43; hyperperfusion to hypoperfusion in 5 cases, hypoperfusion to hyperpeffusion in 2 cases）. Long-term EEG revealed in an increase in the number of normal cases by 20 （40%, 20/39）, and there were 25 fewer cases with epileptiform discharges （66%, 25/38）. These findings demonstrate that long-term control of anti-epileptic drugs partially repaired cerebral perfusion abnormalities and reduced epileptiform discharges in idiopathic epilepsy.展开更多

The patients then orally received a capsule of tall gastrodis tuber powder, a traditional Chinese drug, and underwent single photon emission computed tomography, long-term electroencephalogram, and CT/MRI. Blood drug levels were monitored throughout the study. Before treatment with tall gastrodis tuber, 35 of the 100 cases had abnormal CT/MRI scans; 79 cases had abnormal single photon emission computed tomography images; 86 cases had abnormal electroencephalogram; and a total of 146 abnormal perfusion foci were observed across the 100 subjects. After treatment, the number of patients with normal single photon emission computed tomography images increased by 12; normal electroencephalogram was observed in an additional 27 cases and the number of patients with epileptiform discharge decreased by 29 （34% of 86）; the total number of abnormal perfusion foci decreased by 52 （36%） and changes in abnormal loci were visible in 65 patients. These changes indicate that the administration of tall gastrodis tuber in combination with antiepileptic drugs repairs abnormal perfusion foci in patients with focal epilepsy Our results demonstrate that traditional Chinese drugs can repair abnormal perfusion foci and, as such, are a promising new pathway in the treatment of focal epilepsy.展开更多
