Valproate sodium in refractory seizures: a study of efficacy.

Sodium valproate (N-dipropylacetic acid) is a newly released anticonvulsant drug with a broad spectrum of activity. Twenty-seven children with uncontrolled seizures, predominantly akinetic and myoclonic, were treated with this drug. Encouraging results were noted in those with head-nodding spells, body drops, and myoclonic jerks ("minor motor" seizures). Side effects included occasional gastrointestinal disturbance. No important hepatotoxic complications were noted. Two persons displayed transient neurologic side effects. Of particular interest was the noticeable improvements in mental status noted in 17 of the 27 patients. Some variations in blood level of other anticonvulsant drugs were noted, emphasizing the importance of monitoring these drugs. Valproate sodium provides important improvement in our ability to manage minor motor seizures.

Primitive reflex profile. A pilot study.

Seven primitive reflexes used by physical and occupational therapists in evaluating children with cerebral palsy were each graded on a 0 to 4+ scale to constitute a Primitive Reflex Profile. The reflexes studied were the asymmetrical tonic neck reflex, the symmetrical tonic neck reflex, the tonic labyrinthine reflex, the positive support reflex, the derotational righting reflex, the Moro reflex, and the Galant reflex. The Primitive Reflex Profile was studied in 53 cerebral palsied patients to assess both the feasibility of its administration and its usefulness in discriminating functional levels of ambulation. The Primitive Reflex Profile was administered by at least two members of a team consisting of four pediatric developmentalists and two physical therapists. In using this instrument, the extreme functional groups were clearly defined and showed the expected overlap with the intermediate classification.

Cerebral palsy. A pediatric developmentalist's overview.

Exploration of the history, terminology, and classification of cerebral palsy reveals it as a complex entity. Criteria exist that may make early diagnosis and appropriate intervention possible. Dealing with patients who have cerebral palsy requires recognition of the associated problems and deficits. Comprehensive management usually requires a multidisciplinary setting, which is used to outline the contributions of many therapeutic modalities--developmental pediatrics, occupational and physical therapy, hearing and speech, psychology, social services, special education, ophthalamology, neurology, orthopedics and neurosurgery. The poor prognosis for full function within the community is recognized, as are areas of research that require investigation.

Photosensitive complex partial seizures aggravated by phenytoin.

A 10-year-old girl is described with pure photosensitive complex partial seizures which consisted of a frightening visual phenomenon of seeing "shadow people," then staring blankly with lip smacking and sometimes becoming limp. The seizures were triggered by bright sunlight. With the institution of phenytoin therapy, her seizure frequency increased dramatically without any clinical evidence of toxicity and her phenytoin blood levels were within the therapeutic range. Discontinuation of phenytoin led to a return to baseline seizure frequency. The mechanism by which antiepileptic drugs may aggravate seizures is still not understood; therefore, awareness of this phenomenon is crucial for early diagnosis and appropriate treatment.

An objective method for the assessment of psychosocial problems in adolescents with epilepsy.

Psychosocial problems in adolescents with epilepsy have been of concern for many years, but have been difficult to assess. This article presents the multicenter development of the Adolescent Psychosocial Seizure Inventory (APSI), an empirically based self-report test patterned after the Washington Psychosocial Seizure Inventory, which is used to evaluate psychosocial problems in adults. After pilot work, 120 adolescents with epilepsy from five centers in North America took the APSI and were interviewed by professionals with respect to adequacy of adjustment in eight psychosocial areas. At least one parent or guardian was also interviewed. Interrater reliability of professional ratings in each area was established. Using an item-by-item, empirically based technique, eight psychosocial scales were developed as well as three validity scales. Reliability of the scales was established by both internal consistency and test-retest procedures. Results for each adolescent are presented in profile form. These results give a visual display of the types and extent of problems that likely would be identified in a detailed professional assessment. It is anticipated that the APSI will be of value in a variety of treatment and research contexts.

Efficacy of the ketogenic diet for intractable seizure disorders: review of 58 cases.

The ketogenic diet was developed in the 1920s as a treatment for intractable childhood seizures when few antiepileptic drugs (AEDs) were available. There are still children whose seizures are refractory even to modern therapy, but use of the ketogenic diet appears to be waning. At Johns Hopkins, we continue to believe that the diet is very effective and well accepted by patients and families. To reevaluate our opinion of the efficacy and acceptability of this form of therapy in patients cared for in the 1980s with the newer AEDs, we analyzed the records of 58 consecutive patients who had been started on the diet. Before using the diet, 80% of the patients had multiple seizure types and 88% were treated with multiple AEDs; these children were among our most intractable patients. Despite this, seizure control improved in 67% of patients with the ketogenic diet, and actuarial analysis indicated that 75% of these improved patients continued the diet for at least 18 months. Sixty-four percent had AEDs reduced, 36% became more alert, and 23% had improved behavior. The improvement in these patients with intractable seizures and the length of time that families maintained the regimen indicate that the ketogenic diet continues to have a very useful therapeutic role in selected patients and their families.

Progressive unilateral encephalopathy of childhood (Rasmussen's syndrome): a reappraisal.

Twelve children with Rasmussen's encephalitis underwent hemispherectomy and have been followed for an average of 9.15 years. Our decision-making process leads to early, rather than late operation. Because hemiplegia is inevitable with or without operation, earlier operation may allow such children to resume a more normal life. We postulate that earlier operation may prevent some of the intellectual decline that accompanies the continued seizures and their treatment. In view of the variable pathologic findings and lack of evidence of a viral etiology, we suggest either use of the term "progressive unilateral encephalopathy of childhood" or "Rasmussen's syndrome" in recognition of its heritage.

Clinical and electroencephalographic evidence for sites of origin of seizures with diffuse electrodecremental pattern.

A diffuse electrodecremental ictal pattern (DEP) has been associated with tonic seizures and, less often, with other forms of epilepsy and has been considered to reflect a generalized seizure disorder of diffuse cortical or subcortical (brainstem) origin. In some seizures associated with DEP, however, focal ictal manifestations have been observed. We reviewed the records of all patients admitted to our seizure monitoring unit for 3 years and detected 39 patients with seizures associated with DEP. In 23 of 39 patients, clinical ictal behaviors resembled seizures of unilateral supero/mesiofrontal lobe origin and interictal EEG showed a prominent unilateral frontal component. Nine of 39 had complex absences (CA)/complex partial seizures (CPS); 4 of them were of unilateral frontal lobe origin. Seven of 39 patients had tonic or atonic seizures. Seven patients were studied further with subdural electrodes. Ictal onsets showed a high-frequency frontal lobe discharge. We conclude that in a subgroup of patients a generalized electrodecremental pattern on scalp EEG results from a regional cortical high-frequency ictal discharge originating in a single frontal lobe.

Myelin disorders of childhood: correlation of MR findings and severity of neurological impairment.

Twenty-five children and young adults with myelin disorders were studied to determine how magnetic resonance (MR) findings correlated with the clinical severity of their disease. The MR images were evaluated using both subjective and objective criteria and graded for extent of white matter involvement. Patients were also graded for severity of their neurological and psychological impairment. The assessment of MR severity of white matter involvement using subjective and objective methods showed moderate to good correlation (r2 = 0.473). There was poor correlation between clinical severity of disease and extent of MR involvement for the overall group of children, however (subjective r2 = 0.038, objective r2 = 0.072). Moderate correlation was seen when clinical severity and MR subjective assessment were compared for the specific diseases metachromatic leukodystrophy and subacute sclerosing panencephalitis.
