Deep Brain Stimulation Surgery Advantage: Most Advanced
Technology for Neurosurgery in India
Deep brain stimulation is a way to functionally modulate
variousnuclei in brain like subthalamic nucleus, the
thalamus or globus pallidus without purposefully destroying
or structurally alteringthe brain tissue. In deep brain
stimulation, electrodesare placedin the thalamus (for
essential tremor and multiple sclerosis)or in the subthalamic
nucleus or globus pallidus (for Parkinson'sdisease or PD).
The electrodesare connectedby wires to a type of pacemaker
device (calledan impulse generator, or IPG) implanted under
the skin of the chest, below the collarbone.
Once activated, the device sendscontinuous electricalpulses
to the target areas in the brain, modifyingthe brain circuits
that are responsible for motor symptoms of PD. This is better
than thalamotomy or pallidotomy as it can be modulated as
per needs of the patient and can be done without actually
destroyingparts of the brain.
The IPG can easily be programmed using a computer that sends radio signals to the IPG. Patients are
given specialmagnets so they can externally turnthe IPGon or off.
DMS typically involves Two Separate Surgeries:
Brain surgery - Firstly, doctors have to identify the region of the brain where the electrodes will
be implanted. This is done by analyzing the results of an MRI scan.
Before surgery a stereotactic head frame is fixed to ensure that the patient's head remains still
throughout the whole procedure.
Local anesthesia is used to numb the scalp, and a thin wire with electrodes is implanted into the
brain. Afterwards, a neurostimulator is implanted near the collarbone.
Patients must be awake during the procedure so that the neurologist can ask questions to make
sure the correct areas of the brain are being stimulated.
Chest wall surgery - a day or two after the brain surgery, a pulse stimulator is implanted within
the patient's chest.
A small opening is made behind the ear and the extension wire passes under the skin and
connects to the neurostimulator.
The stimulator is programmed to send electrical pulses to the brain.
Why is deepbrain stimulation performed?
Some people suffering from severe Parkinson's disease cannot be
controlled on medications, and additional methods of alleviating
symptoms, such as DBS, are necessary.
Results of a two-year clinical trial found that DBS greatly
improves overall quality of life and social functioning
among patients in earlier stages of Parkinson's disease.
In addition to treating Parkinson's disease, DBS can
help treat the symptoms of the following conditions and problems:
Dystonia - the largest follow-up record of patients with the most common form of hereditary
dystonia reported very good success rates and lasting benefits from DBS.
Tremors - DBS helped a significant number of patients stop taking medications used
to treat their essential tremors within one year following the surgery.
After the Deep Brain Stimulation procedure
The doctor may advise few antibiotics to prevent infection. The
patient may need to visit the doctor several times after the
surgery to adjust the stimulation with the help of programming.
The doctor may prescribe a detailed medication plan to the
patient. The patient should take some precautions after the
surgery and follow the instructions given by the doctors. He/she
should take care of the incisions and the surgical region on the
head, by keeping it dry and covered. Heavy physical activities
and lifting heavy weights should be avoided for few weeks after
the surgery. Regular follow-up with the treating doctor should be done.
Deep Brain Stimulation Surgery Advantage:
In this surgery we do not injure the brain so it is relatively risk free.
Completely reversible and programmable
Parkinson medications are reduced which results in improvement of drug related side effects.
There is improvement of quality of life in both off and on stage of the disease.
