The clinical and biochemical status of thyroid function of patients with an autistic syndrome was investigated. The study consisted of 13 patients between the ages of 7 and 21 years. There was no clinical evidence for hypothyroidism in any patient, and T3, T4, and TSH concentrations were within the normal range. Two patients who had retarded bone ages were treated with triiodothyronine for 6 months. Hyperthyroidism developed when T3 levels exceeded physiologic concentrations in these patients. The concept that the clinical response to triiodothyronine in autistic patients results from correction of thyroid dysfunction is not supported by these findings.

Basic research in autism is reviewed. There is mounting indication, but as yet inconclusive evidence, of unique physiologic disturbances etiologically related to autism. Additionally there is indication that some of the physiologic disturbances found in autistic children are also present in children with other developmental disorders. Children called autistic probably represent a complex of clinically similar manifestations in a variety of different subgroups of children, each subgroup representing a basically different physiologic disturbance. However, the possibility remains that there is only one basic disturbance that in varying degrees affects many body systems and thus manifests in a variety of overlapping syndromes. Objective markers are needed so as to allow the demarcation of subgroups of autistic children for further study. Possible markers may be decreased duration of postrotatory nystagmus, auditory evoked response deviations, lymphocytic hyporesponsivity, increased blood platelet serotonin efflux, and/or the presence of urinary DMT or bufotenin.

Symptoms are the verbal and nonverbal communicative expressions of experience. At any one time, the symptom is dependent on structural changes, genetic variations, metabolic abnormalities, immunopathic and other disorders, and the totality of social, economic, and situational experience. Complaints of pain may vary with time depending on the interaction of these features in a manner not directly related to the intensity of a noxious stimulus.

An up-to-date review of drug treatment in psychoses of early childhood is presented. At the present time, of all biological interventions in these developmental disorders, drug treatment alone remains a valuable addition or an essential treatment modality of the total treatment. Experience has shown that a therapeutically effective potent drug can make the autistic child more amenable to other therapies, including special education. However, knowledge is lacking about the effect of various psychoactive agents on cognition in this patient population as well as their influence on growth, weight, endocrine systems, and organs. Drugs currently in use treat symptoms, not diseases. A great need for classification in this area persists. The same symptoms may be caused by a variety of etiologic factors, and autism may or may not be the earliest expression of childhood schizophrenia. It is suggested that clinical distinctions be correlated or even improved by certain biochemical, neuroendocrine, and physiological criteria; this also may be of considerable value in predicting whether a child can benefit from a specific drug.

We used a combined behavioral and electrophysiological technique to test the hypothesis that storage of information is impaired in childhood autism. Endogenous event-related potentials associated with the random deletion of stimuli within a regular train of auditory or visual stimuli were examined in three autistic and three normal children. We found that all subjects were able to detect the stimulus deletions, but cortical potentials associated with stimulus omissions were smaller or absent in the autistic subjects. These results are consistent with dysfunction within the system that includes posterior parietal cortex and its connections with the mesolimbic temporal cortex and hippocampus.

Behavioral effects of L-5-Hydroxytrophan (L-5-HTP), administered in combination with carbidopa, were evaluated in three autistic children using direct behavioral observation and parent ratings. Children were assessed under each of four experimental conditions: Baseline, Placebo I, L-5-HTP plus carbidopa, and Placebo II. During the 20-week study two children showed behavioral change that appeared to be unrelated to drug treatment. The findings did not support the hypothesis that a functional deficit in brain 5-HT underlies the autistic syndrome.

In a patient with the Lesch-Nyhan syndrome we found decreased spinal fluid 5-hydroxyindole acetic acid (5-HIAA), the major metabolite of serotonin, and decreased homovanillic acid (HVA), the major metabolite of dopamine, indicating a decrease in monoamine metabolism. Administration of 5-hydroxytryptophan and carbidopa produced an increase in spinal fluid 5-HIAA, indicating that it might be possible to correct the serotonin deficiency in this syndrome, but there were no changes in the marked mental retardation and neurological deficits. Self-mutilation appeared to be suppressed by therapy but the effectiveness of the drugs decreased with time. There were also changes in the spinal fluid concentration of amino acids that might affect brain protein synthesis. These changes were corrected during administration of 5-hydroxytryptophan and carbidopa.

The historical background and early contributions of the Emma Pendleton Bradley Hospital, the first psychiatric hospital for children in the United States, are described. The focus of this report is on the incorporation of the treatment modality of behavior modification into this traditional psychoanalytically oriented program. Beginning with exploratory studies in the mid-1960s, in recent years within the residential center there has been a separate Autistic Unit, in which the major treatment strategy is consistent application of behavior modification principles and programs. Changes that have occurred in the course of developing the behavior modification program are discussed to show some of the positive and negative aspects of introducing such a radical change into a traditional setting. Case studies are included to reveal both the failures and the successes that have been encountered in treating psychotic children with either psychotherapy or behavior therapy. Description of the current status of the program shows that treatment is comprehensive, including psychodynamic and behavioral approaches, medication when warranted, and special education. The role of parents in the program is now very different from that ascribed to them in traditional psychoanalytically guided treatment.

An analysis of attention to task, deviant classroom behavior, and academic productivity data was conducted on four schizophrenic male children to whom an antipsychotic medication was administered. Although the results indicated varying degrees of success as a function of this psychotropic treatment, the medication appeared to have little influence on classroom behavior for three of the children. It was concluded that empirical strategies must be developed for objectively assessing the influence of medications administered for the purpose of controlling the classroom behavior of disturbed children.

During an open clinical trial, 51 schizophrenic patients were treated with Penfluirdol, 34 for 1 year and 17 for a shorter time. The mean dosage of Penfluirdol was 22 up to 28 mg per week. Assessments were made on days 0, 14, 28, 56, 90, 180, 270, and 365 using the AMP system and the EPRS scale of Simpson and Angus. The symptomatology was mainly reduced during the first 3 months of treatment and remained afterwards relative unchanged. Penfluridol showed a good antipsychotic effect on productive schizophrenic symptoms (thought disorders and paranoid symptoms, autism and schizophrenic affective disorders). The dosage used showed only a slight sedative effect and was well tolerated concerning autonomic and extrapyramidal side-effects.
