Neuropsychological Diagnostic Accuracy: Factors That Might Lead to a Wrong Diagnosis and How to Avoid Them
Neuropsychological Diagnostic Accuracy: Factors That Might Lead to a Wrong Diagnosis and How to Avoid Them
Contenido principal del artículo
Los falsos positivos y los falsos negativos en la evaluación neuropsicológica pueden ocurrir debido a diferentes razones y pueden tener consecuencias graves tales como la administración de un tratamiento innecesario que puede causar efectos adversos y la incapacidad de proporcionar un tratamiento oportuno a los pacientes. Por lo tanto, es importante saber qué tanto podemos confiar en el diagnóstico. Los resultados de las pruebas son insuficientes para este fin. Como punto de partida, debemos establecer hipótesis sobre la condición del paciente utilizando la información que hemos recopilado de varias fuentes. Adicionalmente, es necesario utilizar información sobre las propiedades psicométricas de las pruebas, los valores predictivos y las tasas base de los trastornos neurocognitivos y de las puntuaciones bajas. En ausencia de esta información, la interpretación de los resultados debe ser cautelosa. En este artículo se discuten varias estrategias que pueden contribuir a mejorar la precisión diagnóstica.
