It may sound like something out of “Star Trek,” but the latest technology to treat patients with essential tremor is a true technological advance that Swedish helped research and now offers. ExAblate Neuro is a non-surgical technique that uses ultrasound to treat essential tremor, a neurological disorder that causes rhythmic shaking, most commonly in the hands, but also in the arms and legs.

On November 14th, 2013 the FDA gave its approval for an implanted brain stimulator to treat patients with medically refractory epilepsy. Epilepsy is one of the most common neurological disorders affecting nearly 1 in 100 Americans. This device has been under investigation for 10 years at the Swedish Neuroscience Institute (SNI) Epilepsy Center.

As principal investigator for the trial, I led  a team including Dr. Michael Doherty, Dr. Lisa Caylor and Dr. Alan Haltiner, along with the research department at Swedish to investigate the safety and effectiveness of the device through pivotal trials. The results showed that the responsive neurostimulator system (RNS) made by NeuroPace was indeed effective in treating patients with drug resistant seizures.

Why is this so significant? This device represents the first new non-medication treatment for seizures proven to be effective since 1997, and gives new hope to patients whose lives have been put on hold due to seizures. ...

Tremor is a normal physiologic reaction to anxiety or stress, but it is not normal to have a tremor when performing typical daily activities.


People who develop a tremor while eating, drinking, writing or doing other common activities may have a movement disorder called Essential Tremor. This is actually the most common movement disorder, and can affect up to 4% of people over age 40. People who have this disorder can take medications to help minimize the tremor, but they don't often reduce the tremor by more than about half. Deep brain stimulation (DBS) is an excellent treatment option for people with severe tremor, and can nearly eliminate the tremor in many patients. Many patients aren't sure when their tremor is severe enough to warrant surgery, and much of our conversation in the office is to help answer this question.

There is no one answer that is right for everyone, but for me it has to do with how well someone is actually doing in their daily life:


The Patient Rating score is based on responses given during the CAHPS Patient Experience Survey.Responses are measured on a 10 - point scale, with 10 being the best score. These scores are then translated to a 5 - point scale in order to display results in a 5 - star rating.Comments are also gathered from the same survey and displayed in their entirety with the exception of any language that may be considered slander, libel or contain private health information, which will be removed prior to publishing the comments.

Came from out of state for a second opinion. Could not have been more pleased! Compassionate, good listener, didn't rush, professional, extremely knowledgeable.

Very helpful, explained everything very well!

My Provider was excellent. He was through at explaining what my condition was and how to move forward. He listened to all my questions and addressed each one with a clear understanding answer.

These doctors were a direct contrast to the care I have received from Dr. [...] and his office and their nurse and nurse practioner. Dr. [...]'s care we consider negligent. This is why we asked for a 2nd opinion visit with Dr. Gwinn

Dr. Guinne was very personable and nice. I believe he's a great provider. I, however, have a complicated medical history and felt the issues I saw him for were easily dismissed due to the other health condition. [...]

Patient care was great. Patient flow management needs some work
