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.

The diagnosis of "autism" has been used to encompass a heterogeneous group of children who may differ in etiology, clinical manifestations, prognosis, and needed treatment. This paper presents the results of a comprehensive evaluation, using strict diagnostic criteria, of 33 children comprising the entire population of a self-contained unit for "autistic" children in the public school system of Hillsborough County, Florida. Only five of the children fit the criteria for early infantile autism. Six were diagnosed as suffering from schizophrenia, two as atypical developmental disorders. Twelve of the 33 showed evidence of neurological or recognized genetic abnormality, five had specific developmental language disorders, and three were severely retarded, cause unknown. Of the 12 children with evidence of neurological disease, five had chromosome abnormalities evident on cytogenetic study, two had high serum Cux++, one had histidinemia, one had maternal rubella, and three had dyskinesis of unknown origin. The heterogeneous nature of this group underlines the need for comprehensive evaluation of the autistic syndrome.

The article is devoted to the correlation between manifestations of congenital dysontogenesis, the syndrome of Kanner's early infantile autism and early infantile schizophrenia. The article is largely based on the materials of a follow-up study of a cohort of schizophrenics (n = 268) and patients with Kanner's early infantile autism (n = 32). The authors established developmental deviations in the form of a stigmatized, distorted, retarded type in the premanifest premorbid period in patients with early infantile schizophrenia (in 78% of cases). It has been shown that Kanner's early infantile autism is characterized by disorders in the hierarchy of the development of functional systems and their underdevelopment, which allows some authors to refer it to unprogressive dysontogenesis, while others may refer it to congenital apsychotic schizophrenia.

Differential patterns of symbolic expression, through the modalities of language, gesture, play, and drawing, were investigated in 48 psychotic children: 26 with chart diagnoses of autism and 22 with chart diagnoses of schizophrenia. As predicted, autistic children tended to show an absence of symbol use, while schizophrenic children demonstrated complex or differentiated symbol use. A multiple discriminant analysis supported the hypothesized emergence of a "transitional" group of children, defined on the basis of echolalic language, who showed stereotypic or undifferentiated symbol use.

Spontaneous blink rates are controlled by a definable neural system originating in PPRF with facilitatory modulation from SN and superior colliculus and inhibitory modulation provided by cerebellum and occipital cortex. The thalamus may also be involved but the result of its influence is not clear. Reflex blinking is often reduced when spontaneous blink rate is increased and the reverse applies as well. The anatomic control of reflex is primarily in structures in the caudal half of pontine tegmentum and rostral midbrain. However, SN and cerebellum and other structures that regulate blink rate also modulate reflex blinking. Neurochemical control as determined by neuropharmacological experiments is exerted by dopaminergic, cholinergic and GABAergic systems of brain stem. Dopamine activity correlates directly with blink rate whereas agonism of the other two relevant neurotransmitter systems may inhibit blink rate. Clinical implications in central nervous system disease are currently restricted to Parkinson's disease, schizophrenia and autism. In the former illness, reduced blink rate signifies a worsening of the illness and a significant increase in blink rate in patients treated with dopamine agonist may be a harbinger of agonist-induced dyskinesia. In schizophrenia, increased blink rate, even in medication-naive subjects, may signify involvement of the structures that regulate blinking. This is important because these structures are rarely invoked as sites of potential pathophysiological import in schizophrenia. Similar considerations apply to autism except that increased blinking more clearly differentiates this disorder from other forms of retardation.

A conjectured neural integrative defect (schizotaxia), due to a dominant schizogene completely penetrant for a parametric aberration in synaptic signal selectivity (hypokrisia), gives rise under ordinary social learning regimens to schizotypy, a personality showing ambivalence, aversive drift, dereism, autism, and cognitive slippage. Given unfavorable polygenic potentiators (eg, introversion, hypohedonia, and anxiety) and adverse life experiences (eg, childhood trauma or adult misfortune), around 10% develop schizophrenia. That schizophrenia is basically a neurologic disorder does not contradict whatever is known about its psychodynamics, nor preclude efficacy for psychotherapy or other psychosocial interventions. Research should concentrate on soft neurology and psychophysiology as indicators, being closer in the causal chain to the schizogene than psychometric, social, or high-level cognitive processes. Taxometric statistics are appropriate to testing a major locus model not simplistically formulated.

The article briefly reviews the use of modern molecular genetic methods in research into the genetic bases of psychiatric diseases. It raises some basic methodological problems, and describes more recent technologies (RFLP/VNTR markers). Present knowledge about the molecular genetics of Alzheimer's disease, schizophrenia, manic depression, Tourette's syndrome and infantile autism is briefly reviewed in to order show the potential benefits of gene technological methods in this area of research.

Twelve of eighteen preschool children, previously diagnosed as having an atypical pervasive developmental disorder (APDD), using the third edition of the Diagnostic and Statistical Manual (DSM-III) of the American Psychiatric Association, were followed up 5 years later. The follow-up consisted of a pediatric neurodevelopmental evaluation and the administration of the Personality Inventory for Children (PIC), and a scale derived from the criteria for an autistic disorder (AD) in the revised third edition of the Diagnostic and Statistical Manual (DSM-III-R). The children continued to have significant emotional, social, and cognitive problems at follow-up. Almost all required some form of therapeutic intervention, and many received multiple interventions. A broader range of symptoms (including positive symptoms of schizophrenia and signs of affective and anxiety disorders) were noted. A comparison of DSM-III and DSM-III-R criteria for autism with this population revealed a lack of reliability in diagnoses between systems, both with respect to the more specific diagnosis ("autism") and the less specific atypical diagnoses. The authors discuss the implications of these findings with respect to the interpretation of future follow-up studies of autistic and atypical children.

The relationship between amphetamine-induced stereotyped behavior and a neuroendocrine index of arousal, plasma corticosterone (CCS), was investigated. 6-Hydroxydopamine lesions of the caudate-putamen, which produced dopamine depletions of 60%, blocked stereotypy and prolonged the elevation in corticosterone associated with d-amphetamine treatment (5 mg/kg). Similar dopamine depleting lesions of the nucleus accumbens, which attenuated the locomotor, but not the stereotypic, response to AMPH did not have this effect on CCS. This pattern of results supports the hypothesis that stereotypy has a coping function which may serve to alter arousal and further suggests important differences between the nigrostriatal and mesolimbic dopamine projections in modulating the responsiveness of the neuroendocrine system. These results have implications for understanding the function of behavioral stereotypies common to a number of psychopathological conditions, including schizophrenia and childhood autism.

26 children with diagnoses of autism and 22 children with diagnoses of childhood schizophrenia or a variant thereof were compared on the variable of winter birth. Analyses showed that autistic children had a higher proportion of winter births than schizophrenic children. These findings are related to other research linking winter birth to negative-syndrome adult schizophrenia.
