Función neuropsicológica en la fenilcetonuria tratada precozmente: Una revisión

Abstract: La fenilcetonuria (FCU) es un error metabólico congénito que implica una deficiencia de la enzima fenilalanina hidroxilasa. Este proceso da lugar a niveles elevados de fenilalanina y niveles bajos de tirosina. Si no se administra tratamiento aparecen graves secuelas neuropatológicas y neuroconductuales. La puesta en práctica de la detección sistemática de recién nacidos y el tratamiento dietético precoz ha reducido significativamente esta morbilidad. A pesar de una función intelectual general relativamente con… Show more

“…In comparison with the prevalence confirmed in other research, this prevalence is significantly higher. In the overall population of children whose age ranges from six to twelve years old, 4 to 12% have ADHD [28,29] . Lower prevalence was recorded by Beckhauser et al [30] who have demonstrated the presence of manifestations of ADHD in thirteen cases (38.2%), with the majority of them having the hyperactive or impulsive form of ADHD.…”

“…Phenylalanine levels are also associated to the results of tests evaluating these aspects. 6 Processing speed is also affected in patients with phenylketonuria, which also seems to be related to the involvement of executive functions. 7 Therefore, it is critical to keep phenylalanine levels within normal ranges and monitor their variability, since the wider the variability the worse the outcome in IQ and executive functions.…”

“…5 También se observan déficits en las funciones ejecutivas, como planificación, organización y memoria operativa, a pesar de un buen control dietético, y se asocian, igualmente, los niveles de fenilalanina a los resultados en los tests que las evalúan. 6 La velocidad de procesamiento se ve afectada en los pacientes con fenilcetonuria, lo cual parece relacionarse también con la afectación de las funciones ejecutivas. 7 Por ello, es importante mantener los valores de fenilalanina en rangos de normalidad y controlar su variabilidad, ya que se ha observado que, a mayor variabilidad, peores resultados en el CI y las funciones ejecutivas.…”
