Two case reports illustrate the therapeutic response of congenital nystagmus to a diet eliminating synthetic food colors, synthetic food flavors, the antioxidant preservatives butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), and a small group of foods thought to contain a natural salicylate radical. A brief discussion of the hyperkinetic syndrome is offered with the proposal that a variety of neurologic and neuromuscular disturbances (grand mal, petit mal, psychomotor seizures; La Tourette syndrome; autism; retardation; the behevioral component of Down's syndrome; and oculomotor disturbances) may be induced by identical chemicals, depending upon the individual's genetic profile and the interaction with other environmental factors. It is perhaps the failure to integrate all the signs presented by the various clinical patterns with hyperkinesis or Minimal Brain Dysfunction (MBD) under a single heading that eye muscle involvement manifested as either nystagmus or strabismus has not been emphasized as part of the hyperkinetic syndrome.

Alpha rhythm is classically described as a bilateral posterior rhythm of substantially constant frequency in the range of 8-13 Hz which is enhanced by mental relaxation and blocked by attention. Since the full expression of alpha rhythm has been shown to occur coincident with puberty, it is possible that the establishment of alpha rhythm is subject to neuroendocrine influences which govern psychosexual maturation. There is ample evidence to indicate that the pineal gland is implicated in cerebral maturation and psychosexual development. Nocturnal plasma melatonin levels have been shown to decline progressively throughout childhood reaching a nadir at puberty. Since administration of melatonin has been reported to block alpha rhythm, it is proposed that the progressive decline in melatonin secretion during childhood facilitates the maturation of the alpha rhythm. Consequently, the presence of alpha rhythm could be used as a neurophysiological marker for the activity of the pineal gland and disorders associated with absent or delayed maturation of the alpha rhythm such as autism, dyslexia, personality disorders, epilepsy, Tourette's syndrome, and schizophrenia might be related to disturbances of pineal melatonin functions in early life. Moreover, since the EEG patterns associated with cerebral immaturity (i.e., slowing, absence of alpha activity) are more pronounced in the left hemisphere, this hypothesis implies differential influence of the pineal gland on hemispheric maturation potentially accounting for the vulnerability of the left hemisphere to cerebral insults.

At the present time, neuroleptics are indicated for the treatment of acute psychotic states as well as Tourette's syndrome in children and adults. Neuroleptics may have a useful role in the attenuation of problem behaviors, such as stereotypies, hyperactivity, self-injury, and aggressive outbursts in infantile autism, pervasive developmental disorder NOS, and mental retardation, but they do not improve the underlying condition. Neuroleptics are not the agents of first choice for treatment of hyperactivity or aggression in children who do not have major developmental handicaps. Common and troublesome side effects associated with neuroleptic use in children and adolescents include sedation, extrapyramidal symptoms, and withdrawal dyskinesias; therefore, close monitoring is required. Neuroleptics should be used cautiously and only as an adjunct to other nonpharmacologic interventions.

This study examined the linkage between elevated blood serotonin in autism and the presence of circulating autoantibodies against the serotonin 5HT1A receptor. Information was also obtained on the diagnostic and receptor specificity of these autoantibodies. Blood serotonin was measured as was inhibition of serotonin binding to human cortical membranes by antibody-rich fractions of blood from controls and from patients with childhood autism, schizophrenia, obsessive-compulsive disorder, Tourette's, and multiple sclerosis. The results showed elevated blood serotonin was not closely related to inhibition of serotonin binding by antibody-rich blood fractions. Inhibition of binding was highest for patients with multiple sclerosis and was not specific to the 5HT1A receptor as currently defined. Although inhibition was not specific to autism, the data were insufficient to establish if people with autism differed from normal controls on this measure.

During the past two decades psychopharmacologists have made considerable strides in establishing the safety and efficacy of psychotropic drug therapy for childhood behavior disorders. Most of the research has focused on children with disruptive behavior disorders, autism, or mental retardation, but more recently other disorders such as depression, obsessive compulsive disorder, separation anxiety (school refusal), and Tourette syndrome are also receiving attention. Psychopharmacotherapy has often been a matter of controversy, with most issues pertaining to either the appropriateness of medication (e.g., rationales for treatment, alternative interventions, toxicity, iatrogenic effects) or inadequacies of clinical management (e.g., availability of services, drug assessment procedures, limitations of research). This article presents a brief overview of the safety and efficacy of psychotropic drugs and the issues associated with their use in clinical settings.

Recent twin and family studies have demonstrated a genetic factor in Gilles de la Tourette syndrome, some cases of infantile autism, enuresis, specific reading disability, sleepwalking, night terrors, common fears and anxiety. Family studies have been used to elucidate the nosological relationship of psychiatric disorders; e.g. anorexia nervosa (to affective disorder), Gilles de la Tourette syndrome, and sleeptalking. Advances in biochemical genetics and in enzyme polymorphisms suggest that there are wide individual variations in the adverse effects of drugs and that dosage should be tailored to the individual patient. Recently molecular genetic methods have been introduced to psychiatry, but a major breakthrough in this field appears to be still years away.

The histories of 10 children with autistic disorder or pervasive developmental disorder (PDD) cooccurring with familial Tourette syndrome (TS) are presented. Evidence from the histories of the patients and their relatives combined with other reports of cases of cooccurrence of TS and autism provides support for the hypothesis that TS may be responsible for cases of coocurrence of the disorders, contributes significantly to the etiological heterogeneity of autistic disorder and that a portion of cases of autism may actually be a result of homozygosity for the TS gene. In addition, the presence of affective disorders and autistic-like syndromes or mild disturbances of social relatedness in some of the pedigrees suggests the hypothesis that TS may be responsible for a subgroup of families with cooccurring affective and autistic disorders and for some cases of familial aggregation of autism-PDD.

Children with autism or pervasive developmental disorder (PDD) and Tourette syndrome (TS) share a number of symptoms. Forty-one cases have been reported in which PDD patients subsequently developed TS. We term this PDD----TS. We describe an additional 16 such patients plus 3 families where a close relative of a TS proband had autism. There was a high frequency of alcoholism, drug abuse, obsessive-compulsive, and other behavior disorders in the relatives of these patients. This frequency was virtually identical to that observed in relatives of individuals with TS only. We suggest there is an intimate genetic, neuropathologic relatedness between some cases of PDD and TS. Many observations have led us to suggest that the genetic defect in TS may be a mutation of tryptophan oxygenase and that TS is inherited as a semidominant semirecessive trait, i.e., homozygosity for a common gene which shows some expression in the heterozygous state. We propose that some types of PDD are inherited in the same fashion and by the same gene. This would explain the similarity of symptoms, frequent evolution of PDD into TS, the apparent recessive inheritance of PDD despite no increase in consanguinity, the high frequency of behavior problems in the relatives of PDD----TS patients and the serotonin abnormalities.

A review is presented of the diagnosis and drug treatment of the more common psychiatric and developmental disorders in the pediatric population. Where applicable, DSM III (Diagnostic and Statistical Manual of Psychiatric Disorders, III) criteria are utilized to describe the behavioral syndromes. The indications for usage and appropriate dosages of antipsychotics, antidepressants, anxiolytics, stimulants, and lithium are described. Those disorders discussed are attention deficit disorder, conduct disorders, anxiety disorders, sleep disorders, schizophrenia, autism, Tourette's syndrome, mental retardation, depressive illness, manic depressive illness, eating disorders, and enuresis.

We review the English-language literature on Asperger's syndrome (AS), with particular reference to diagnostic criteria and differentiation from infantile autism and personality disorders, and describe six cases seen in practice: all met DSM-III criteria for 'atypical pervasive developmental disorder'. Three also developed Tourette syndrome: the co-occurrence of the two disorders, and methods of intervention, are discussed.
