Tremor Series: Why tremor?

In the introductory episode for the Tremor Special Series, Dr. Elan Louis tells us about the epidemiology of tremor as well as patients' and health care providers' awareness (or lack thereof). He guides us through his journey from when his mentor suggested that he'd look into familial essential tremor to the most important discoveries of the last two decades. Finally he gives us a glimpse of what's about to come and why tremor matters.
