In a face-to-face questionnaire-based survey involving a total of 111 essential tremor (ET) patients and their relatives, we demonstrated a general lack of genetic insight amongst our study subjects. There was no significant correlation between genetic knowledge of ET and age, level of education, disease duration or severity. A proactive effort is needed to encourage physicians managing ET patients to incorporate genetic information and education into their practice.
