Introduction: learning disorders (ID) are alterations of the infantile development that are manifested mainly in difficulties for learning academic abilities, with high incidence of electroencephalographic abnormalities of different grades: fused waves (Pi) in occipital areas, focal or widespread paroxysms of 6-14 Hertz, tip discharges (focal), especially in temporal and occipital areas. Objetives: to correlate the electroencephalographic findings with the different lD, in children between 7 and 12 years of age who attend the outpatient clinic of the department of neurology of the Pediatric Hospital "Dr. agustín zubillaga" of Barquisimeto, state of lara, Venezuela. Methods: an electroencephalogram was performed in all patients and a descriptive and transversal study was carried out to determine the correlation in school children that completed the inclusion Results: in 31 children, 54. 8% resulted normal, and 45.1% abnormal the largest percentage was of slow layouts, 64.and 2%, followed by focal 35.6% and widespread 14.2%. the abnormal electroencephalograms were more frequent in boys (32.2%), in whom the focal layouts prevailed (35.6 %) vs. girls (12.9%), in whom prevailed widespread layouts (14.2%). Conclusions: the diagnosis of learning disorders is mainly clinical, psychological and academic, and is not ruled out by a normal neurological examination. the electroencephalogram constitutes a useful tool in its evaluation, with appropriate sensibility and low specificity. in many occasions, it is the only objective evidence of cerebral dysfunction.
