De Novo Nonepileptic Seizures after Cranial Surgery for Epilepsy: Incidence and Risk Factors

Clinical features of Psychogenic Nonepileptic Seizures (PNES): analysis of a Brazilian series

“…Four patients had been previously subjected to temporal lobectomies and presented with PNES afterwards. They represent 3.4% of our own series of 118 temporal lobectomy (related to MTS) cases, which is consistent with the 3.5 to 4.6% incidence, reported in other series (14,15) and a little below the 8% reported by Henry and Drury (16) . Glosser et al (17) described a "disproportionate number of postsurgical PNES patients as female, with a primary neuro-dysfunction on the right hemisphere".…”

“…There were 10 male and 35 (78%) female patients, with a mean age of 27.4 y/o (range 4-58 y/o). A mean of 3.3 (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) events were recorded per patient. In 15 (33%) patients the NES duration was less than a minute, in 21(47%) last between 1 and 5 minutes, in 8(18%) the duration was between 5 and 25 minutes and 1 patient presented with a NES lasting over an hour.…”

Failure of temporal lobe resection for epilepsy in patients with mesial temporal sclerosis: results and treatment options

“…It will also rule out nonepileptic seizures, which may occur in a small percentage of patients. 9,14,35 It is our experience as well as others' that reoperation might be of benefit in selected patients (Table 3). We believe that further surgical intervention can be considered for those patients with ipsilateral temporal seizures, with or without residual mesial structures, and for those with new extratemporal seizures if a lesion or epileptogenic cortex can be identified.…”
