The family and the child with epilepsy.

Reports documenting psychosocial epiphenomena of chronic illness in individuals with that illness have been common in recent years. Few studies, however, have been concerned with how illness might affect the family. Those that have appeared in the literature often lack critical controls (i.e., control groups) and often fail to investigate possible links between illness-specific variables (i.e. chronicity, inhibition of mobility) and psychosocial outcomes on the family. The present study of 45 families focused on how children with epilepsy affect their families' functioning relative to families with a child with diabetes and families with no chronically ill members. The results suggest several areas of child and family adjustment (i.e. child self-concept, family communication, family cohesion) in which the families of epileptic children have great difficulty. Implications of these results are discussed with regard to differential influences of various chronic illnesses on families and family-based preventive and remedial treatment programs.

Childhood migraine and somnambulism.

Based on a sample of 222 children from four diagnostic groups, a high frequency of somnambulism in children suffering from migraine headache is reported. The strength of the association between somnambulism and childhood migraine raises the possibility that somnambulism might be considered as a minor diagnostic criterion in the clinical diagnosis of childhood migraine. This association may further clarify the nature of the serotonin abnormality underlying migraine.

Coincident infantile autism and Tourette syndrome: a case report.

A 15-year-old boy who had been diagnosed as having infantile autism (IA) at two years of age was found to have Tourette Syndrome (TS) in adolescence. This case report represents the second coincident finding of IA and TS in an adolescent autistic boy. The implications of a co-occurrence of IA and TS are discussed in the light of our current understanding of abnormalities in neurotransmitter metabolism common to both conditions.

Childhood migraine and motion sickness.

The incidence of motion sickness among 222 children in four diagnostic categories--migraine, nonmigraine headaches, seizure disorders, and learning disabilities--was compared. Motion sickness was found to be an associated feature in 45% of the cases of childhood migraine, in contrast to a 5% to 7% incidence in the other groups. Therefore, it is suggested that motion sickness be regarded as an additional reliable minor criterion in the diagnosis of childhood migraine. Hypotheses of common central and peripheral mechanisms underlying both conditions are offered.

Emotional concomitants of childhood epilepsy.

On the basis of the distinguishing features of unpredictability, overt manifestation of symptom, and loss of control in epilepsy, a number of hypotheses about possible emotional concomitants of childhood epilepsy are offered. Comparing fifteen epileptic children with groups of diabetic and healthy children, matched for chronological age, sex, mental age, socioeconomic status, and family variables, the following findings emerged. Epileptic children are more likely than their diabetic or healthy peers to attribute control over even successful events in their lives to external sources. The perception of control by powerful others or by unknown factors was especially pronounced with regard to social events. In addition, epileptic children as a group were found to have lower self-concepts (particularly with regard to their popularity) and to be more anxious than their peers. The clinical and research significance of the findings are discussed.

Spatial perspective-taking and pretend play.

To test the hypothesis that pretend play has a facilitatory effect on young children's spatial perspective taking, 45 children were individually engaged in fantasy or non-fantasy interactions with an adult, after which they were administered 3 standard perspective-taking tasks by a blind examiner. Evidence in support of the hypothesis was found.

Rapid two point kenetic determination of plasma lactic acid.

1. Plasma levels of L-lactic acid were determined employing a two-point kinetic, lactic dehydrogenase method without a protein free filtrate preparation. 2. The method was characterized with regards to precision, linearity, recovery and accuracy. 3. Regression analyses were accomplished by comparison of the kinetic and standard enzymatic end point procedures. 4. Clinically significant values are obtained within 50% less time than routine methods presently employed.
