<h2>What is deep brain stimulation?</h2>
Deep brain stimulation (DBS) is a surgical procedure where electrodes are implanted into specific areas of the brain. These electrodes send electrical impulses that regulate abnormal brain activity to treat various medical conditions.
&nbsp;
The deep brain stimulation treatment works like a pacemaker for the brain. A small device placed under the skin in the chest sends signals through a wire to the electrodes, helping patients control symptoms, such as those from Parkinson&#8217;s disease or tremors, more effectively than using medication alone.
&nbsp;

Deep brain stimulation (DBS) functions by adjusting the neural signals responsible for movement-related symptoms. By delivering precise electrical pulses, this treatment can be customized to focus on different brain regions depending on the specific medical condition being addressed. DBS methods typically focus on the following areas:
&nbsp;
<ul>
<li style="font-weight: 400">Globus pallidus internus: This area is targeted to do deep brain stimulation for movement disorders, primarily for treating Parkinson’s disease and dystonia.</li>
<li style="font-weight: 400">Thalamus: This part of the brain integrates sensory and movement information; it is the main target for treating <a style="color: #00826a" href="https://www.phyathai.com/en/pyt2/article/2625-essential-tremors">essential tremor</a> and deep brain stimulation Parkinson&#8217;s disease.</li>
<li style="font-weight: 400">Subthalamic nucleus: This region is targeted to help the body prepare for movement, which is beneficial for patients with Parkinson’s disease and dystonia.</li>
</ul>
&nbsp;
To ensure the highest level of accuracy, neurosurgeons utilize noninvasive imaging like MRI or CT scans to map out the best location for the leads before the operation begins. During the actual surgery, many specialists use a monitoring wire to track nerve cell responses, allowing them to pinpoint the perfect spot for the DBS system to do its work.
&nbsp;
<h2>Possible side effects after deep brain stimulation</h2>
