Para los investigadores, de la Universidad de Maastricht (Países Bajos), este hallazgo plantea la cuestión sobre si la depresión puede ser uno de los primeros síntomas del Parkinson.
Estudiaron un registro con 1.358 pacientes diagnosticados de depresión a lo largo de un período de 15 años y se compararon sus datos con más de 67.000 controles. Ambos grupos fueron seguidos durante 25 años. El número de pacientes depresivos que desarrollaron Parkinson fue de 19, por 259 en el grupo control.
Los autores opinan que los niveles bajos de serotonina característicos de la depresión también desempeñan un papel en el origen del Parkinson, algo que ya han comprobado estudios previos.
