Uthman found VNS therapy to lack the side effects associated with some anti-epileptic medications such as drowsiness, lack of coordination and blurred vision. VNS side effects are minimal and usually decrease over time. Patients may experience coughing initially, or a mild tingling in the neck or vibrating voice during stimulation. VNS therapy should not be compared to resective epilepsy surgery or medications, as it stands alone as a separate mode of therapy. It is not meant to replace resective epilepsy surgery, Uthman said, but in well-selected patients can offer a good chance for seizure freedom.
Patients have more options now.
