Estudios preliminares han establecido que los pacientes en estadios iniciales de la enfermedad de Parkinson pierden entre un 40-60% de neuronas dopaminérgicas antes de que los síntomas sean detectados.
Los agonistas dopaminérgicos son fármacos de elección para el tratamiento de la enfermedad de Parkinson. Imitan la acción de la dopamina, cuya pérdida es causada por la enfermedad, mediante la estimulación directa de los receptores de la dopamina en el cerebro.
"Aunque persiste el debate sobre el tratamiento de la enfermedad de Parkinson inicial, y teniendo en cuenta que todos los tratamientos deben ser individualizados para cada paciente, este estudio añade importantes elementos de información al conocimiento del tratamiento inicial de la enfermedad , ha comentado el Dr. Kenneth Marek, presidente del Instituto de Alteraciones Neurodegenerativas de New Haven (Estados Unidos).
