We studied 20 patients with continuous repetitive psychogenic seizures simulating status epilepticus. Most patients received intravenous doses of multiple anticonvulsants. Our definition used for status epilepticus was that of Delgado-Escueta et al,1 at least 30 minutes of repetitive seizures without regaining consciousness. Nineteen of 20 patients were young women, all but one under 40 years of age. Sixteen of these patients had a history of childhood seizures. In over 50% of patients, seizures continued until respiratory arrest and intubation occurred. Thorough neuropsychological testing and psychiatric interview were done after cessation of the acute episode. Long-term outcome and prognosis depended on definitive psychiatric diagnosis. Repetitive psychogenic seizures simulating status epilepticus are not uncommon, and such patients may incur serious iatrogenic complications from treatment for status epilepticus. Appropriate management and long-term prognosis may be determined by the type and severity of the underlying psychiatric disorder.

Background.—Migraine is common in the pediatric population. Levetiracetam, an anti‐epileptic drug, has shown some efficacy in small prospective adult headache studies.

We followed 23 patients with pediatric migraine, ranging in age from 7 to 17 years, who were treated with preventive divalproex sodium for migraine prophylaxis. Patients were evaluated for the presence or absence of comorbid psychiatric disorders or epilepsy to assess the possible differential effects of divalproex therapy. Doses ranged from 3.1 to 32.9 mg/kg/day. Seven patients had comorbid psychiatric disorders, whereas six patients had epilepsy (three rolandic, two generalized, and one indeterminate). Fifteen patients had a greater than 50% reduction in migraine; six patients became headache free. Divalproex doses used were not statistically different among the three groups. A favorable response and headache freedom were more likely in patients with migraine alone or with comorbid epilepsy, and less likely in patients with psychiatric comorbidity. Divalproex was well tolerated, and no significant side effects were reported. No notable changes were noted in behavioral problems, and patients with epilepsy were well controlled. In our cohort of patients, divalproex was most effective in patients with migraine alone or comorbid epilepsy. (J Child Neurol 2001;16:731-734).

Chronic daily headaches are an increasingly recognized neurologic issue in children. Frequent headaches can be a source of significant disability and family discord with work/school absenteeism. Medication overuse and emotional disorder would significantly impact treatment and progression. This study examined the frequency of emotional and behavioral problems in children and adolescents with chronic daily headache compared with age-related healthy controls. Prevalence of medication overuse in this chronic daily headache group was evaluated. Otherwise healthy children and adolescents with chronic daily headache (according to International Classification of Headache Disorders-II criteria) were enrolled from the Headache Clinic. Healthy controls were prospectively enrolled from physician offices. Multiple psychological rating scales, headache diaries, presence of medication overuse, and disability surveys (Pediatric Migraine Disability Assessment Survey) were completed. A total of 57 healthy controls and 70 patients were studied. The sample consisted largely of females, many of whom (60%) had medication overuse before medical treatment. Headache patients had significantly more symptoms of anxiety, depression, and somatization compared with controls. Patients with chronic daily headache were at higher risk for emotional disorders, and medication overuse was a significant occurrence, suggesting a need for multisystem treatment approach.

Introduction.—Currently, no medications are approved for pediatric headache prophylaxis in the United States. Zonisamide is an antiepileptic drug with preliminary studies suggesting some efficacy in the adult headache population.

Objective.—To determine whether behavioral and psychiatric disorders occur more frequently in school‐age children with migraine headache. To also elucidate treatment response related to comorbid psychiatric or behavioral diagnosis.

Article abstract The authors studied six children with repetitive psychogenic seizures severe enough to mimic status epilepticus. All received IV antiepileptic drugs in an emergency setting. Most had a family history of epilepsy. Affective and anxiety disorders predominated as comorbid psychiatric diagnoses. Acutely stressful situations precipitated all episodes of nonepileptic status epilepticus. With aggressive psychotherapeutic intervention and pharmacologic treatment of their underlying psychiatric diagnosis, the patients improved.

We examined the relationship between magnetic resonance imaging (MRI) cerebral findings and clinical evaluations in 66 patients with clinically definite multiple sclerosis (MS). MRI observations included total number and location of lesions visualized, degree of periventricular involvement, degree of degeneration of the corpus callosum, and extent of generalized parenchymal atrophy. Overall physical disability was evaluated by the Kurtzke Expanded Disability Status Scale (EDSS) and individual symptoms were rated according to the Kurtzke Functional Systems (FS) scale. Our results suggest that MRI brain abnormalities are significantly related to the overall severity of disease, but MRI is not particularly useful to predict the presence or absence of individual symptoms. These findings do suggest that the MRI may provide useful information to monitor clinical progression of patients with MS, but the lesions visualized need not always be symptomatic nor are we sure that all symptomatic lesions, particularly in the spinal cord and optic nerves, will be visualized.
