Webb27 maj 2024 · Selective parvalbumin (Pv)-positive inhibitory interneurons activation in vitro (by optogenetics), distant from the seizure focus, caused propagation blocking and shortening of seizure duration. On the other hand, excitation of these Pv interneurons at the epileptic focus did not prevent the ictal generation even resulting in its promotion. Webb4 juni 2011 · In patients who develop seizures due to recurrent infarction, a cardioembolic source should be suspected and, if proved, anticoagulant treatment should be started or readjusted.
