Abstract
Introduction

Studies that have compared the cognitive alterations of the children of parents with bipolar disorder (CPBD) versus the children of control parents (CCP), present heterogeneous results due to the studies’ methodological differences, the age of the population studied, and the lack of standardisation of the measures used for the different neurocognitive domains. The objective was to compare the neurocognitive profile of CPBD versus CCP to observe if there are differences that could be proposed as possible endophenotypes of BD.

Results

A total of 107 individuals (51 CPBD, and 56 CCP) with ages between 6 and 16 (mean, 12.2±2.80) years of age were evaluated. Seventy-four point five percent of the CPBD group had some disorder compared to 67.9% of the CCP group. Tests such as letter-F phonemic verbal fluency, letter-S phonemic verbal fluency, overall F-A-S phonemic verbal fluency, story recall and retrieval, and Wisconsin perseverative errors showed a difference with a small effect size, but with a high degree of uncertainty.

Conclusions

The CPBD did not have differences in their neurocognitive profile in comparison with CCP. Both groups have a high prevalence of psychopathology, which is a factor that could explain the lack of differences in neurocognitive performance.

Resumen
Introducción

Los estudios que han comparado las alteraciones cognitivas de los hijos de padres con trastorno bipolar (HPB) con las de los hijos de padres de control (HPC) presentan resultados heterogéneos debido a las diferencias metodológicas de los estudios, la edad de la población estudiada y la falta de estandarización de las medidas utilizadas para los diferentes dominios neurocognitivos. El objetivo es comparar los perfiles neurocognitivos de los HPB y los HPC para observar si existen diferencias que puedan llegar a proponerse como posibles endofenotipos del trastorno bipolar.

Resultados

Se evaluó a un total de 107 individuos (51 HPB y 56 HPC) de 616 (media, 12,2±2,80) años de edad. El 74,5% del grupo de HPB presentó algún trastorno en comparación con el 67,9% del grupo de HPC. Las pruebas de fluidez verbal fonológica-letra efe, fluidez verbal fonológica-letra ese, fluidez fonológica F-A-S total, recuerdo y recuperación de una historia y errores perseverativos del Wisconsin mostraron una diferencia con un tamaño del efecto pequeño, pero con alto grado de incertidumbre.

Conclusiones

Los HPB no presentaron diferencias en el perfil neurocognitivo en comparación con los HPC. Los 2 grupos presentaron una alta prevalencia de psicopatología, lo cual es un factor que puede explicar la falta de diferencias en el desempeño neurocognitivo.
