New research out of Columbia University suggests that Essential Tremor (ET), the most common form of tremor, may be more complex than once thought. According to author Elan D. Louis, MD, MSc, “There is growing evidence that ET may be a family of diseases rather than a single entity.” His study, Essential tremors: a family of neurodegenerative disorders? was recently published in the Archives of Neurology.
Dr. Robert Goodman from the Center for Movement Disorders says, “This study represents a very important new insight into the nature of ET and helps us understand the various subtypes of ET. An important feature that is common to almost all subtypes is hand tremor. Thalamic Deep Brain Stimulation (DBS) remains an effective treatment for many patients with ET, who have disabling hand tremors. It is important to know that this treatment generally provides longstanding tremor control or marked reduction, with improved hand function and ability to perform various important activities of daily living.”
