New Brain Stimulator Approved to Treat Epilepsy

December 05, 2013
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. ...

How much tremor is too much?

February 26, 2013
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:

Patient Ratings and Comments
About Our Survey

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.

Recommend De. Gwinn for sure.
Swedish Patient

Since I wanted to discuss alternatives to surgery, I felt I was dismissed & given instructions to follow-up with another provider - who NEVER called, nor did Dr. Gwinn's office after multiple calls from me over 2 1/2 weeks - I'm still waiting.
Swedish Patient

I really appreciate Dr. Gwinn's kind help to us, listening, addressing our concerns, and showing thorough compassion.
Swedish Patient

Excellent doctor!
Swedish Patient

love, love, love this provider/surgeon

I was met by Dr. Gwinn's PA who discussed my case with my husband and I. I did not remember meeting him in nICU until later in our conversation. He discussed the possibility of taking a steroid to help and left the room. After, one of the nurses came in to give me a copy of the synopsis of the visit and then PA returned. As we were leaving we happened to run into Dr. Gwinn. We talked a bit and he preformed a wound check in the hallway after following my lead to look at it. I am concerned that the PA was a bit casual in his mannerisms and that he did not perform a wound check early in his meeting with me. I was 10 days post op for a biopsy.
