RESUMEN
El trastorno del espectro autista (TEA) es un desorden del desarrollo complejo caracterizado principalmente
por carencias en la comunicación y en la interacción social, así como por patrones de
comportamiento, intereses o actividades repetidas y restrictivas. La prevalencia es mayor en niños.
Se desconocen las causas exactas de las anomalías o irregularidades en las conexiones neuronales
subyacentes a la enfermedad, pero etiológicamente el tea se considera un padecimiento multifactorial.
Se han propuesto diferentes mecanismos fisiopatológicos para explicar las manifestaciones del
trastorno, entre los que destaca una alteración en el balance de señales excitadoras e inhibidoras
mediadas por el glutamato y el ácido gamma amino-butírico (GABA), respectivamente, en circuitos
que controlan funciones cognitivas como la memoria y aprendizaje. El tratamiento del tea consiste
en apoyo psicopedagógico y farmacológicos, cada caso debe ser individualizado. Esta revisión
aborda aspectos relevantes de los mecanismos fisiopatológicos, características clínicas y terapéutica
de este trastorno.
