Changing the World, Changing the Lives In More than 50 Countries of the World With Our 20 Years of Vagus Treatment Experience We Are Here for a Brand New Quality of Life Our tVNS® health solutions help thousands of patients to discover a brand new quality of life. What is tVNS®? tVNS® is a medical device for the treatment of symptoms of sympathovagal imbalance and was specially developed for patients who are not free of symptoms despite drug therapy. tVNS® stimulates the branch of the vagus nerve in the auricle through the skin with gentle electrical impulses. Signals are passed on to the brain via special nerve fibers: first in the brain stem and then in higher centers. The treatment with tVNS® is applied by patients independently. It has been used by thousands of patients and is a treatment with very few side effects. tVNS® is indicated to treat sympathovagal imbalance in the following conditions: ​ ​ Anxiety Migrain Autism Cognitive Impairment Depression Fibromyalgia E p ilepsy Inflammation Pr ader-Willi Syndrome Sleep Disorders Stroke Tinnitus Asthma Crohn's Disease Atrial Fibrillation Parkinson's tVNS® CARE Therapy Tracking​ THE MOST EFFECTIVE WAY TO GET RESULTS FROM tVNS®* For patient-driven medical device treatments that the patient can apply at home without the supervision of a doctor, the most important need for the success of the treatment is the preparation of a protocol specific to the patient's needs and the remote follow-up by the doctor and an expert team to see whether the patient can use the device correctly. tVNS Care®, o ur unique digital health service, where a patient-specific program is prepared based on the protocols of similar patients in more than 50 countries and all details of the treatment can be followed online by our expert teams.

tVNS PARKINSON EXPERIENCE Barry Hanner is a famous Baritone opera singer. He has been using the tVNS device for Parkinson's disease for about two years. Before tVNS, he was suffering from disturbance of equilibrium. He uses it four hours a day at least five times a week. He says that the biggest effect of tVNS is eliminating the disturbance of equilibrium. " tVNS was recommended to help me with my Parkinson's disease symptoms. I use it at least 5 times a week. I realized that the tVNS device has eliminated the balance disorder caused by Parkinson's disease.The device's biggest advantage is providing such a recovery without the requirement for any surgical intervention and without being exposed to the side effects of drugs. I have been using tVNS device for over 2 years and will continue to use it." Barry Hanner. We are working for a better life...

tVNS Nemos, that has improved the quality of life , in more than 3000 patients with epilepsy in the world since 2012, was has been applied to the first pediatric resistant epilepsy patient in Turkey last week. tVNS Nemos, which is the size of a mobile phone, stimulates the ear branch of the vagus nerve with the help of a special electrode headset, reduce the frequency and severity of epilepsy seizures by providing vagus nerve stimulation without the need for any invasive intervention and placement of a device in the body as a result of a total of 4 hours of sessions applied every day. As tVNS Turkey, we aim to reach patients who are suitable for tVNS vagus stimulation therapy and to increase the quality of life of our epilepsy patients.
