ABSTRACT

Introduction: Children with specific language impairment (SLI) represent an heterogeneous group affecting different linguistic dimensions, both in reception and in the expression. Stark and Tallal, proposed the current clinical criteria including: hearing level, emotional and behavioral status, intellectual coefficient (IQ), neurological status, motor skills and speech reading level, all within normal range, making the diagnosis by exclusion. The white matter has been associated with the speed processing and function connectivity, and abnormalities associated with signal hyperintensities in children with delayed language development has been estimated at 17-26% of cases.
Objetive: To describe brain MRI findings and to identify the risk factors in children with specific language impairment in the period from July 2011 to July 2012.
Methods: Observational, prospective, cross-sectional analytical study including patients seen at the neurology clinic of the Hospital “Dr. Rodolfo Nieto Padrón”. Brain magnetic resonance imaging was performed in twenty patients; we did a descriptive analysis of the demographic data and findings in the brain MRI.
Results: A total of 50 patients were included; a 4:1 ratio in males was reported. Attention deficit hyperactivity disorder was associated with TEL. We used the Rapin and Allen classification in which the most frequent type was type IV, 20 brain MRIs of 50 patients were performed with TEL, reporting 16 resonances with white matter hyper intensities and 4 normal magnetic resonances, with 80% reporting white matter hyperintensities in different regions primary the periventricular zone.
Conclusions: The most common findings in brain MRI were hyperintensity of white matter in periventricular region following at the occipital lobes, parietal lobes and semi-oval centers. Factors associated with specific language impairment such as family history, chronic degenerative diseases, history of drug delivery and consumption were not associated with this pathology. We observed that Attention deficit hyperactivity disorder was significantly associated with specific language impairment.
