Before You Consider VNS Therapy
Vagus nerve stimulation (VNS) is approved by the FDA as an option to treat epilepsy and treatment-resistant depression. However, experts at 麻豆学生精品版 recommend you get a thorough evaluation for surgery as the first step. Work with your providers to find out which surgery is best for you.
What Is the Vagus Nerve?
Most people don鈥檛 know the vagus nerve by name. It runs from the base of your brain, through your neck and down each side of your body. (Vagus means 鈥渨andering鈥 in Latin.)
The vagus nerve plays a role in several key functions, including:
- heart rate,
- breath, and
- the ability to relax.
It鈥檚 even responsible for 鈥済ut feelings,鈥 because it tells your brain how your body鈥檚 organs are doing at any given time. The mind-body connection is very real.
Vagus Nerve Disorders
Problems linked with vagus nerve can include:
- obesity,
- anxiety,
- mood disorders, such as treatment-resistant depression,
- bradycardia,
- gastrointestinal diseases,
- chronic inflammation,
- fainting, and
- seizures.
Vagus Nerve Stimulator Surgery
You will first have a surgery to implant the vagus nerve stimulator. The surgery is an outpatient surgery, which means you can leave on the same day as your surgery. It鈥檚 also relatively quick.
Your doctor will use general anesthesia to make you comfortable. He or she will then make an incision in the left side of your neck to attach a spiral-shaped electrode around the nerve (which looks like a piece of linguine). Then your doctor will make a second incision in your chest to implant a pacemaker called a pulse generator or vagus nerve stimulator. There are no incisions on your head.
Vagus Nerve Stimulation Device Programming
A few weeks after surgery, you鈥檒l return to the hospital where your doctor will program the VNS device to deliver electric impulses in regular intervals (for example, 30 seconds on and off for five minutes). While the pulse generator won鈥檛 detect seizures, you can use a special magnet to manually start the device if you feel a seizure coming.
You can also use the magnet to turn off your VNS device, like when you鈥檙e speaking or singing in public鈥擵NS therapy can make your voice hoarse. You might also have a slight pain in your neck when the currents are surging.
While VNS therapy is not a cure for movement disorders or other conditions, it can:
- reduce the length and severity of seizures,
- improve your mood,
- improve your overall quality of life.
