PURPOSE To determine whether differences in clinical manifestations of psychogenic nonepileptic events are associated with differences in outcome and whether the length of illness before diagnosis correlates with outcome. METHODS We reviewed ictal videotapes and EEGs in 85 patients diagnosed with exclusively nonepileptic psychogenic seizures during(More)
We studied biopsy results in a kindred with the Lafora form of progressive myoclonic epilepsy. Four members of a family with known consanguinity presented as teenagers with seizures, myoclonus, dementia, and ataxia. After the diagnosis was established by brain biopsy in the first patient, many efforts were made to obtain a tissue diagnosis in the three(More)
We evaluated pelvic thrusting as a potential diagnostic sign and localizing indicator of ictal onset. By reviewing the video-EEG results of patients with temporal lobe epilepsy, frontal lobe epilepsy, generalized epilepsy, and pseudoseizures. Pelvic thrusting occurred in 4% of right and 2% of left temporal lobe epilepsy patients, in 24% of frontal lobe(More)
In 41 patients with EEG features of benign epilepsy of childhood with centrotemporal spikes (BECCT), we noted associated generalized spike-wave discharges (GSWD) in 14.6% and multiple independent sharp wave foci in 9.8%. The presence or absence of these EEG features was not predictive of the clinical course. The high incidence of GSWD in children with BECCT(More)
We reviewed EEGs from children whose history and clinical course was compatible with benign partial epilepsy of childhood with centrotemporal spikes. In 21% of patients with a single EEG focus, the discharge was outside the centrotemporal area. In 37.5% of patients with more than one focus, one was in the centrotemporal area while the other was not. We(More)
The coagulation cascade plays an important role in brain edema formation caused by intracerebral blood. In particular, thrombin produces brain injury via direct brain cell toxicity. Seizures and increased cerebral electrical activity are commonly associated with intracerebral blood and are possible effects of thrombin leading to cell injury in the brain. In(More)
OBJECTIVE To examine the frequency of interictal epileptiform activity (IEA) in elderly patients with epilepsy. DESIGN AND METHODS From a consecutive 13,905 EEGs recorded over 5 years at a university hospital EEG laboratory, 558 studies were performed on outpatients aged 60 years or more. Medical record review identified 125 patients in whom a confident(More)
Felbamate (2-phenyl-1,3-propanediol dicarbamate) has a favorable preclinical profile in animal models of epilepsy. We present the results of a double-blind, randomized, placebo-controlled clinical trial in patients with partial seizures. Criteria for entry included a requirement for four or more partial seizures per month despite concomitant therapeutic(More)
The incidence of seizures increases significantly after age 60, mainly because of an associated rise in the prevalence of such etiologies as stroke, brain tumors, and toxic-metabolic disturbances, including alcohol or drug misuse and diabetes. The differential diagnosis must rule out transient ischemic attacks, syncope, and psychiatric disorders, among(More)
Twenty-six children (16 boys and 10 girls) with hypsarrhythmia and infantile spasms (IS) were studied at the University of Michigan EEG Laboratory in a 4-year period. Six (2 boys, 4 girls), had asymmetric hypsarrhythmia with a preponderance of both slowing and epileptiform activity over one hemisphere. All 6 had the symptomatic form of IS, 4 with dysplastic(More)
