Brain stimulation therapies can play a role in treating certain mental disorders. Brain stimulation therapies involve activating or inhibiting the brain directly with electricity. The electricity can be given directly by electrodes implanted in the brain, or noninvasively through electrodes placed on the scalp.
How do they put electrodes on your head for a hair transplant?
The technician will measure your head and mark where to place the electrodes. These spots are scrubbed with a special cream that helps the electrodes get a high-quality reading. The technician will put a sticky gel adhesive on 16 to 25 electrodes, and attach them to spots on your scalp.
How do they put electrodes on your head for EEG?
These spots are scrubbed with a special cream that helps the electrodes get a high-quality reading. The technician will put a sticky gel adhesive on 16 to 25 electrodes, and attach them to spots on your scalp. Once the test begins, the electrodes send electrical impulse data from your brain to the recording machine.
What are brain electrodes and how do they work?
These sensors, called electrodes, pick up activity from cells inside your brain called neurons and send them to a machine, where they show up as a series of lines recorded on moving paper or displayed on a computer screen.
Why would a doctor order an electromyography?
These symptoms may include tingling, numbness, or unexplained weakness in the limbs. EMG results can help the doctor diagnose muscle disorders, nerve disorders, and disorders affecting the connection between nerves and muscles. Some doctors may refer to electromyography as an electrodiagnostic exam. Why is electromyography performed?
How long do the effects of deep brain stimulation last?
When patients ask how long benefits of deep brain stimulation last, "we can now reassure them that, at least for subthalamic nucleus deep brain stimulation, improvement in motor complications lasts beyond 15 years and is often accompanied by improvement in quality of life," the editorialists wrote.
What is the procedure for deep brain stimulation?
Deep brain stimulation involves implanting an electrode deep within the brain. The amount of stimulation delivered by the electrode is controlled by a pacemaker-like device placed under the skin in your chest. A wire that travels under your skin connects the device to the electrode.
What does a deep brain stimulator do?
Deep brain stimulation (DBS) is a surgery to implant a device that sends electrical signals to brain areas responsible for body movement. Electrodes are placed deep in the brain and are connected to a stimulator device. Similar to a heart pacemaker, a neurostimulator uses electric pulses to regulate brain activity.
What type of therapy is deep brain stimulation?
Deep brain stimulation (DBS) is a neurosurgical procedure that uses implanted electrodes and electrical stimulation to treat movement disorders associated with Parkinson's disease (PD), essential tremor, dystonia and other neurological conditions.
Can deep brain stimulation cause dementia?
For Now: DBS Does Not Increase Risk of Dementia (So people with dementia typically are not good candidates for the surgery.) But many wonder if the procedure might increase risk of dementia, significant cognitive changes that interfere with daily life, in those without cognitive changes.
Are you awake during deep brain stimulation?
Standard DBS is performed while you are awake and requires that you stop taking any medications to control your movement disorder. During the surgery, the neurosurgeon uses specialized monitoring equipment to determine a safe path to the location in the brain where the electrodes will be implanted.
Who is not a good candidate for deep brain stimulation?
ET candidates for DBS must have medication refractory tremor defined as having failed maximal titrations and preferably combinations of a beta blocker, primidone, and possibly a benzodiazepine. There are other medications that have been found effective in some patients with ET and these may be tried as well.
Does insurance cover deep brain stimulation?
WILL DBS BE COVERED? Most public and private health insurance companies, including Medicare, cover approved uses of deep brain stimulation, including essential tremor treatment. If you're concerned about therapy coverage, talk with your doctor's office and insurance company.
Can you drive after deep brain stimulation?
The majority of patients resumed driving shortly after DBS surgery. Three months preoperatively, 66 of the 110 patients (60.0%) were active drivers, but 64.7% of patients expected at that time to be able to drive postoperatively. 50.9% of all patients resumed driving within a postoperative period of 3 months.
What is brain therapy called?
Electroconvulsive therapy (ECT) is a procedure, done under general anesthesia, in which small electric currents are passed through the brain, intentionally triggering a brief seizure. ECT seems to cause changes in brain chemistry that can quickly reverse symptoms of certain mental health conditions.
Can deep brain stimulation change your personality?
So far, little is known about the impact of DBS on patients' personality. Nevertheless, DBS induced changes in personality have been observed in some cases [15, 24], while others have found no or little impact on personality [2, 8, 28].
Can deep brain stimulation cause seizures?
In the majority of patients (up to 100% in some studies), DBS implantation–associated seizures occur within 48 hours after implantation.
Overview
Why It's Done
Risks
- Although deep brain stimulation is generally considered to be low risk, any type of surgery has the risk of complications. Also, the brain stimulation itself can cause side effects.
How You Prepare
- First, weigh the pros and cons
Deep brain stimulation is a serious and potentially risky procedure. Even if you might be eligible for deep brain stimulation, you and your doctors must carefully weigh the risks and potential benefits of the procedure. - Next, prepare for surgery
Before surgery, you'll likely need medical tests to make sure that deep brain stimulation is a safe and appropriate option for you. You may also need brain-imaging studies, such as an MRI, before the surgery. These studies help to map the areas of your brain that will have the electrodes impl…
What You Can Expect
- During the surgery
In general, here's how surgery for deep brain stimulation works: 1. Brain surgery. For the brain surgery portion, your care team fits you with a special head frame to keep your head still during the procedure (stereotactic head frame). Then, team members use neuroimaging (brain MRI or … - After the procedure
A few weeks after surgery, the pulse generator in your chest is activated in your doctor's office. The doctor can easily program your pulse generator from outside your body using a special remote control. The amount of stimulation is customized to your condition, and may take as lon…
Results
- Deep brain stimulation won't cure your disease, but it may help lessen your symptoms. If deep brain stimulation works, your symptoms will improve significantly, but they usually don't go away completely. In some cases, medications may still be needed for certain conditions. Deep brain stimulation isn't successful for everyone. There are a number of variables involved in the succes…

Terminology
Mechanism
- The brain is still not well understood, nor is the reason for the treatment effects ECT (shock) therapy has on some individuals. It is known that ECT affects hormones, neuropeptides, neurotrophic factors, and neurotransmitters in the brain. All of this may come together to explain how ECT works in treatment.
Preparation
- A full physical is generally needed before shock therapy. Because general anesthesia will be administered, one should not eat or drink 8-12 hours before the shock treatment. This helps to prevent any vomiting during the procedure. Other exams like an electrocardiogram (ECG) may also be given before ECT to ensure the procedure is safe and appropriate.
Treatment
- Shock therapy is performed in a hospital, sometimes in an area specifically set aside for this treatment. An intravenous (IV) is inserted to provide anesthetic medication. Vital signs are taken initially and continuously throughout the shock therapy treatment. An anesthesiologist administers anesthesia and after you are asleep, places a tube in your throat to help you breathe…
Results
- When you awake from the anesthesia, you may be confused and tired. You will likely experience short-term memory loss around the time of the procedure. With multiple treatments, this may increase. Adverse cognitive effects tend to be the most concerning factors around ECT and tend to affect the frequency and duration of treatments and whether ECT is offered at all. Your vital si…
Uses
- It is most common to see shock therapy used in severe cases of depression. Shock therapy is also performed to improve the condition of the following disorders:1
Risks
- The complications associated with ECT / shock therapy are often related to electrode placement with bilateral placement (an electrode by each temple) typically showing greater unwanted cognitive effects than unilateral placement (one electrode at the temple and the other on the forehead). Risks of shock therapy include slow heart beat (bradycardia) and rapid heartbeat (tac…
Prognosis
- Shock treatment for depression often produces a dramatic improvement in symptoms, especially in elderly individuals, sometimes during the first week of treatment. While it is estimated many of these patients will experience a future return of depression symptoms, the prognosis for each episode of depression is good. Mania also often responds well to shock treatment. The picture i…
Overview
Why It's Done
- An EEG can determine changes in brain activity that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder. An EEGmight also be helpful for diagnosing or treating the following disorders: 1. Brain tumor 2. Brain damage from head injury 3. Brain dysfunction that can have a variety of causes (encephalopathy) 4....
Risks
- EEGsare safe and painless. Sometimes seizures are intentionally triggered in people with epilepsy during the test, but appropriate medical care is provided if needed.
How You Prepare
- Food and medications
1. Avoid anything with caffeine on the day of the test because it can affect the test results. 2. Take your usual medications unless instructed otherwise. - Other precautions
1. Wash your hair the night before or the day of the test, but don't use conditioners, hair creams, sprays or styling gels. Hair products can make it harder for the sticky patches that hold the electrodes to adhere to your scalp. 2. If you're supposed to sleep during your EEGtest, your doct…
What You Can Expect
- During the test
You'll feel little or no discomfort during an EEG. The electrodes don't transmit any sensations. They just record your brain waves. Here are some things you can expect to happen during an EEG: 1. A technician measures your head and marks your scalpwith a special pencil to indicate wher… - After the test
The technician removes the electrodes or cap. If you had no sedative, you should feel no side effects after the procedure, and you can return to your normal routine. If you used a sedative, it will take time for the medication to begin to wear off. Arrange to have someone drive you home. …
Results
- Doctors trained to analyze EEGs interpret the recording and send the results to the doctor who ordered the EEG. Your doctor might schedule an office appointment to discuss the results of the test. If possible, bring along a family member or friend to the appointment to help you remember the information you're given. Write down questions to ask your doctor, such as: 1. Based on the r…
