RESUMEN
La apnea obstructiva del sueño (AOS) se ha asociado a deterioro cognitivo.

OBJETIVO:

Identificar factores asociados a bajo rendimiento cognitivo (BRC) en adultos con sospecha de AOS.

MÉTODO:

Se realizó evaluación cognitiva empleando la Evaluación Cognitiva de Montreal (MoCA); se consideró BRC un puntaje inferior a 21. El diagnóstico de AOS fue mediante poligrafía respiratoria de 5 canales, según índice de apnea-hipopnea (IAH). Se evaluó también calidad de sueño, síntomas depresivos, entre otros.

RESULTADOS:

En 91,5% de 320 pacientes consecutivos se confirmó el diagnóstico de AOS. El promedio de MoCA fue 20,6 puntos. El grupo con BRC tenía mayor edad, menor escolaridad; mayor frecuencia de hipertensión arterial y diabetes mellitus, y desaturaciones de la oxihemoglobina de mayor magnitud. No hubo diferencias de gravedad según IAH entre ambos grupos.

COMENTARIO:

Los pacientes con BRC presentan factores de riesgo asociados a deterioro cognitivo, y mayor magnitud de desaturaciones de la oxihemoglobina.
ABSTRACT
Obstructive sleep apnea (OSA) has been associated with cognitive decline.

OBJECTIVE:

To identify factors associated with low cognitive performance (LCP) in adults with suspected OSA. MATHOD Cognitive evaluation was performed using Montreal Cognitive Assessment (MoCA), and scores lower than 21 were considered LCP. The diagnosis of OSA was made using 5-channel respiratory polygraphy, according to the apnea-hypopnea index (AHI). Sleep quality, depressive symptoms, among others, were also evaluated.

RESULTS:

In 91.5% of 320 consecutive patients the diagnosis of OSA was confirmed. The MoCA average was 20.6 points. The group with LCP was older, less educated, were more likely to have hypertension and diabetes mellitus, and with more severe oxyhemoblobin desaturations. There were no differences in severity according to AHI between both groups.

COMMENT:

Patients with LCP have risk factors associated with cognitive impairment, besides more severe oxyhemoglobin desaturations.
