[Relationship between neurological deficit and intelligence quotient in children and adolescents].

INTRODUCTION: The relationship between developmental and mental deficits due to genetic or acquired causes is well established. However the possible relationship between neurological signs and intellectual development has not been sufficiently studied. OBJECTIVE: We have conducted a transversal study to test the possible association between neurological signs and psychometric measures in children and young adolescents. PATIENTS AND METHODS: 123 patients were neurologically explored (ages between 54-185 months), 36 girls and 87 boys. These subjects were neurologically and psychometrically tested during a period of 3 years. Contingency tables, chi squared tests, discriminant analysis and ROC curves were used for statistical analysis. This statistic allowed to establish the contingencies between neurological signs (presence or absence) and intelligence quotient (IQ) groups (low and normal scores). RESULTS: The results showed a statistically significant relationship between IQ and the presence of 7 neurological signs (chi2=6.213; p=0.013). The discriminant analysis classified correctly 77.2% of subjects. The ROC curves indicated a high sensitivity and specificity if subjects presented more than 3 neurological signs. The frequency analysis established the more discriminant neurological signs. CONCLUSIONS: The obtained results in children with learning and behavioural disabilities suggest comorbidity between low IQ and neurological signs. This association is more marked in the group of children than in the pre- and adolescent group.

[Developmental stuttering and acquired stuttering: resemblances and differences].

INTRODUCTION: In this study the authors analyse, clinically, dysphemia (DP) and acquired stuttering (AS). AIMS. The aim of this study was to evaluate whether AS is a variant of DP or whether it is an entity that shares a common element: stuttered speech. PATIENTS AND METHODS: The authors studied 13 patients with AS and 36 with DP. In addition to the clinical evaluation, electroencephalogram (EEG) and cranial computerised axial tomography (CAT) scans were performed, with a special interest in secondary symptoms/signs, laterality profiles and pathological, personal and familial history. RESULTS: There was a notable predominance in males in both groups. AS began either in infancy or from any other age; DP only started in infancy. The most frequent organic pathology, for both DP and AS, was a severe traumatic brain injury, followed by cerebral anoxia/hypoxia, cerebrovascular accident (CVA) and others. One important element in both groups was the presence of stuttering and high percentages of left-handedness in the families. In AS, all patients were right-handed. None of the patients who experienced the onset of AS in infancy improved/yielded during adolescence. CONCLUSIONS: Both DP and AS are cases of "neurogenic" stuttering because they display organic and/or functional pathologies in the two groups, which invalidates the term "developmental", since AS also occurred in infancy. DP and AS have an element in common: they both share a genetic predisposition on which the organic/functional pathology then gives rise to the clinical symptoms, although this does not account for the absence of tics in AS.
