ABSTRACT
Introduction: diverse neurological diseases are present in pediatrics and respond to a great number of causes, that is, infectious, genetic, metabolic and degenerative, among others. Within the clinical method in neurology, the genetic diagnosis is related to the etiological diagnosis. There are very few publications that show the frequency of neurogenetic diseases as an etiologic group.
Objective: to describe the frequency of some neuropediatric diseases in the Neurogenetics Service of the Institute of Neurology and Neurosurgery.
Methods: a prospective and descriptive research study was conducted in the 2008-2010 period. The patients were grouped by age and the frequency rate was estimated for infantile spinal muscular atrophy, Dechenne/Becker-type muscular dystrophy, the static lesions of prenatal genetic origin in the central nervous system, and finally for the classification of the groups by the type of inheritance.
Results: the universe of study was composed by 161 patients of whom 72.6 % were males, for a sex ratio of 2.5. The schoolchildren were the majority (37.8 %) and the average age was 5 years. Duchene type muscular dystrophy was the most frequent (24.8 %). Of the total number, 41.40 % was classified as recessive autosomal inheritance. The results agreed with those of the literature.
Conclusions: the hereditary neuromuscular diseases and the static lesions of the central nervous system of prenatal genetic origin are the most common reasons for the request of genetic counseling in the Neurogenetics Service.
