En la edición electrónica de "Annals of Neurology" se publican los sorprendentes resultados de un estudio en el que se ha encontrado una asociación entre la disfunción cerebral subyacente a la epilepsia y el riesgo de suicidio.
La investigación, firmada por un equipo de la Columbia University (Estados Unidos), también sugiere que la depresión y el suicidio podrían presentar distintos mecanismos cerebrales.
Según los autores, por razones desconocidas, la depresión incrementa el riesgo de desarrollar epilepsia y también es frecuente en personas epilépticas que experimentan muchas crisis.
Compararon datos tanto de epilepsia como de depresión en 324 pacientes epilépticos y en 647 controles. Comprobaron que la historia de depresión aumenta el riesgo de epilepsia, pero el resultado más chocante fue que las personas epilépticas tienen 4 veces más probabilidades de intentar suicidarse antes de experimentar una crisis.
A juicio de los autores, este hallazgo sugiere claramente la existencia de mecanismos cerebrales subyacentes comunes para la conducta suicida y la epilepsia.
