[Autoantibodies to glutamate receptors in children with chronic posttraumatic headache].

Autoantibodies (aAB) to AMPA (Glu R1 subunit) and NMDA (NR 2A subunit) glutamate receptors were studied in blood serum of 60 children, aged 7-16 years, with chronic posttraumatic headache after mild skull injury. All the children were divided into 2 groups: group 1 included 48 children with concussion of the brain, group 2--12 children with brain contusion. Group 1 was divided into 2 subgroups: subgroup 1a comprised 34 children with single concussion and subgroup 1b--14 children with repeated concussion. The aAB level was determined 6 months and 1 year after skull injury. The aAB concentration was expressed in percents to the control level being considered significant if the increase was higher than 120%. The increased NMDA aAB level was observed during the first year after skull injury. In the la subgroup, the NR2 aAB level in blood serum was 145 +/- 12,6%, in the 1b one--108 +/- 12,4%, in group 2--165 +/- 34%. The content of aAB to AMPA receptors was elevated only in children of lb subgroup and group 2 (150 +/- 16,8% and 167 +/- 31,3%, respectively). The EEG examination of this group revealed the nonspecific paroxysmal discharges in 18% of cases and epileptiform activity in 6% of children. The results obtained suggest that children with posttraumatic headache have elevated levels of aAB to glutamate receptors, hyperstimulation of which reflects hypoxic processes in the brain, and are in need of metabolic therapy.

[Methodological approaches to investigation of autonomic nervous system functions in young children].

Techniques for investigation of a functional condition of autonomic nervous system in young children--anamnesis questionnaire, a list of basic vegetative disorders and screening table for vegetative tonus evaluation--were elaborated. These tools have been tested in a longitudinal study of more than 200 children, aged 3 months to 5 years, with various psychic disorders, 143 being related to high-risk group for schizophrenia, and were proved to be higher informative, simpler and more convenient for practitioners.

[Nerve growth factor auto-antibodies in children with various forms of mental dysontogenesis and in schizophrenia high risk group].

The level of autoantibodies (AAb) to nerve growth factor was evaluated in blood serum of 163 children with different forms of mental dysontogenesis of endogenic, residual-organic, psychogenic and deprivative origin. Significant elevation of the level of AAb was found in all forms of psychic dysontogenesis. The most significant elevation of the level of AAb (p < 0.01), as compared with the controls (45 children), was characteristic for endogenic forms of dysontogenesis (schizophrenia, early children's autism, schizotypic diathesis). The level of AAb was also found as an indicator of the acuteness of the pathologic state. Besides, its elevation was observed 1-2 weeks prior to the onset of the clinical exacerbation. Elevation of AAb level was also found in psychic dysontogenesis of residual-organic nature (children with perinatal encephalopathy), but it was not so significant as compared with the controls (p < 0.05%). The analysis in the age dynamics of children from this group revealed, that AAb level may serve as some prognostic index of the severity of psychic dysontogenesis. The level of AAb differs some states in schizotypic diathesis and deprivative dysontogenesis, which are clinically quite similar. The method for the estimation of serum AAb level may be proposed as screening in prophylactic medical examination of children from the first year of life under conditions of pediatric outpatient service for identification of risk-groups by psychic dysontogenesis to perform early special psychoprophylaxis.

[Electroencephalographic correlates of schizophrenic type mental disorders at an early age in childhood].

Electroencephalographic study was performed in 30 children of 1-3 years old from the group with the high risk of schizophrenia. Clinical observation of the patients was performed in the period of EEG recording and follow-up study was also made during 10-12 years. Three groups of patients were picked out with the differences in both clinical and electrophysiologic indices. Bundle beta-activity was registered on EEG in the cases of an active schizophrenic process. A presence of the spindles of the sleep and their dominance on EEG were characteristic for children with nonprocessual disorders of psychopathic-like type with disinhibition of the drives. Hypersynchronism of delta- and theta-activities were observed in the cases of schizotypic diathesis and an early children's autism with the predominance of paroxysmal somato-autonomic disorders.

[Nerve growth factor auto-antibodies in the sera of mothers of schizophrenic children and children from high risk group].

A level of autoantibodies (aAB) to nerve growth factor (NGF) was measured in blood serum of children from 4 groups: 1) schizophrenic patients; 2) children from the families, in which one of the parents suffered with schizophrenia (high risk groups of schizophrenia); 3) children with residual-organic damages of CNS; 4) control group. This index was also determined in their mothers. Significant elevation of a titer of aAB to NGF was observed in blood of children from groups 1 and 2 as well as in their mothers, as compared with 3 and 4 groups. Among the mothers of the children from 1 and 2 groups there were met women with different endogenous mental disorders, with the disorders of personality as well as mentally healthy women. An increase of a level of aAB to NGF was found in all the women from groups 1 and 2, independently of their mental status including mentally healthy women. Such results allow to consider elevated level of aAB to NGF as a risk factor of mental pathology.

[Autoantibodies to the nerve growth factor in disorders in the mental development of young children].

80 children aged 1-3 years were examined. They were divided into 3 groups by the degree and structure of disorders of mental development: children with predominant delay of speech development (group 1); with a delay of psychic development due to organic damage of CNS (group 2); with deviation of psychic development and the most pronounced psychopathologic symptomatology (group 3). There was a significant (p < 0.001) elevation in the blood level of autoantibodies to nerve growth factor (NGF) in children from all groups as compared with control one (0.75 +/- 0.24 OD units). The level of such autoantibodies also increased during transition from the 1st to the 3d group (0.95 +/- 0.24 in group 1; 1.13 +/- 0.27 in group 2; 1.24 +/- 0.4 in group 3). The correlations allow us to suppose that the level of autoantibodies to NGF might be considered, together with some other signs, as a potential molecular marker indicating a disorder in the development of nervous system.

[A method for determining the mental development of children up to 3 years old--the Schedule for the Neuropsychological Examination of Infants].

GNOM--is standard method of estimation of health state in babies and infants with determination of coefficient of mental development. Method's basis appears to be tasks and tests allowing to evaluate (in scores) the state of the main neuropsychiatric spheres, namely: sensory, motor, emotional, cognitive and social-communicative. Method exists both in ordinary and computer variations. It was approved in process of observation of 500 children. GNOM permits to perform the screening of children in big children's contingents. It may be used by either the physicians or other medical personnel as well as by the parents too.

[Clinical computed tomographic correlations in children from a group at high risk for schizophrenia].

Computed tomography (CT) was performed in 189 individuals: in 44 children of schizophrenic parents (high risk group, HRG), in 39 parents with schizophrenia or with schizophrenic disturbance, in 56 children with schizophrenia, in 50 children with consequences of early organic damages of central nervous system (mental retardation syndrome and generalized tic syndrome). The frequency of CT changes was equal in the mentioned groups but their character was quite different. The widening of brain's liquor system (89.7%), the signs of frontal and temporal atrophia (31%), foci of decreased density of cerebral brain's matter, closer in subcortical ganglia and periventricular zone, and different anomalies of brain were observed in HRG children.

[Motor disorders and their correction in children from a high-risk group for the development of schizophrenia at an early age].

A 7-year study of locomotor function in 103 children born in the families where one of the parents suffered from schizophrenia has found no locomotor abnormalities only in 20% cases. The rest of them had: disorders of the general locomotor activity, disorders of the static and locomotor development, symptoms of extrapyramidal and cerebral regulation dysfunctions, changes of the muscle tone, ataxia, pathologic locomotor phenomena, speech disorders. The severity of the above disturbances and their variability correlated with the child's general and mental development. Attempts of relevant locomotor correction including massage provided good results.

[Clinico-psychopathological aspects of borderline mental disorders in infancy].

The authors summarize the data obtained during a comprehensive examination of 200 children of the first year of life with borderline mental disorders. Abnormalities of vegetative and instinctive regulation, psychomotor and affective disorders which are, as a rule, of the borderline nature, occupy the leading position in the structure of the above-indicated disorders. The latter ones are associated frequently enough with different types of development retardation and neurological deviations from normal. The signs of differentiating between these disorders and analogous ones within the framework of endogenous mental pathology are depicted. The role is demonstrated of etiological factors (perinatal encephalopathy, constitutional, psychosocial, disturbances of the mother-child system). The studies attest to the basic demonstrability of psychopathological abnormalities and to their great diversity in infants.

[Development of the locomotive and neurologic symptoms in the offspring of schizophrenics during the first few years of life].

The author provides the neurological characteristics and the follow-up data on the development of locomotion in 36 children aged 3 months to 3 years born to schizophrenic patients. Three variants of motor development were distinguished: the first one--early and proper development; the second one--short-term retardation at some stages, namely before the age of 1 year and 4 months, with intermittent episodes in the development and a proper or little changed formula of the postural and motor development; the third one--appreciable retardation and perversion of the motor developmental formula, insufficiency of the extrapyramidal and cortical components of the motor act, preserved even after 3 years of age. Among the discovered neurological symptoms, disorders in the system of gaze innervation, vocal and motor disorders, motor stereotypies, disturbances of the extrapyramidal and cortical component of the motor act, the hydrocephalic syndrome can be attributed to more specific ones as regards the schizotypic dysontogenesis. They were distinguished for using in further follow-up of the children.

[The effect of the earthquake in Armenia on the mental health of the pediatric population of the damaged regions].

The authors relate neuropsychic disorders in children and adolescents of Armenia in the acute period and 3 months after the earthquake. The pathological disorders were dependent on the individual reactivity of the child and environmental factors. 3 months after the earthquake 31% of the examines demonstrated marked mental disturbances. The prevalence of mental pathology among the population groups living in the regions damaged by the earthquake demands organization of specialized assistance for the population.

[Sanatorium-health resort treatment of children with hereditary diseases of the neuromuscular system].

The study was aimed at determining the efficacy of sanatorium treatment of patients with hereditary neuromuscular abnormalities. Sanatorium methods of treatment combined with drug therapy were found to be more effective as compared with outpatient or hospital treatment. The sanatorium treatment proved most effective in children with congenital myopathy, Charcot-Marie neural amyotrophy, and Roussy-Levy polyneuropathy. Improvement in the general status and motor functions was correlated with certain improvement in dynamometric findings, locomotor tests, stabilization of a number of parameters of electroneuromyographic examination, and biochemical findings. The results point to the necessity of setting up specialized departments in childhood neurologic sanatoria or sanatoria specializing in the treatment of children with individual forms of neuromuscular diseases at health resorts which can provide treatment with sulphide waters or therapeutic mud.
