title: [Clinical diagnosis of dyslexia].
abstract: In 5 years of experience at the Instituto Nacional de la Comunicacion Humana, 302 clinical histories showed the diagnosis of dyslexia. The following parameters were studied: age, sex, heredofamilial history, gestation, psychomotor development, clinical picture, examination of the language (type, reading, spontaneous writing, dictation, mathematic concepts), laterality, scholarship, scholar failures, psychological study. The following results were obtained: Dyslexia was more important or frequent between 5 to 8.9 years of age. Males predominated 3:1. The heredofamilial history was important. Dyslexia prevailed in products of the first gestations. A high disturbance was found in the psychomotor development of a large percent of dyslexic patients. Examination of language was also important. Dyslexia was more frequent in right-handed patients. Scholar failures in one or more instances were found. The psychological study must be done. If dyslexia is diagnosed on time, it may be prevented and all unwanted sequelae may be avoided.
