¿Qué es el temblor esencial?

El temblor esencial es un trastorno del sistema nervioso que genera movimientos involuntarios. Se presenta generalmente en las manos, pero puede aparecer en la cabeza, el mentón o con una combinación.

Esta afección también es conocida como temblor postural o de acción. “Es simétrico en ambos miembros y aparece al hacer alguna actividad. No aparece cuando está en reposo”, afirmó el neurólogo Hernán Pavón.

El especialista del Instituto de Neurociencias del Hospital Alemán en Argentina agregó que “generalmente las personas con temblor esencial tienen antecedentes de familiares con el trastorno”.

La prevalencia de ese tipo de temblor para todas las edades es baja. Se estima que el 1,13% de la población lo tiene aunque es más frecuente en personas mayores.

Su tratamiento suelen ser medicamentos betabloqueantes, ansiolíticos y relajantes musculares, anticonvulsivos, entre otros. Estos fármacos también se usan para otras patologías.

Habitualmente el trastorno no genera complicaciones. Con la medicación los pacientes mejoran, aunque no desaparece. En algunos casos, el estrés social hace que el temblor aumente su intensidad”, concluyó Pavón.
