Patient's Query

Hello doctor,

What are the ways a neurosurgeon can get to someone's brain? Along those lines, what does a person typically experience after having their skull opened or a bone flap?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome to icliniq.com. Regarding your concern, I would explain that there are a lot of ways that a neurosurgeon can reach the brain: 1. Craniectomy: Trepanation and excision of the skull, which is called open surgery. 2. Endoscopy, through a device like a tube with a camera, which is called closed surgery. 3. Gala knife, which is a radiation technique, to treat brain lesions without opening the skull, but through radiation therapy. 4. Transphenoidal excision, through the nose, in case of pituitary tumors. This method avoids trepanation and uses anatomical ways through the nasal bone. 5. Endovascular catheterization to treat brain aneurysm and other vascular malformations by inserting catheters in the jugular vein, without trephination of the skull. In all these cases, the patient experiences mild pain, mainly due to the wound, which is well dominated by Ibuprofen or Tylenol. So, just like other surgery but the main thing is that brain tissue does not hurt. So, nothing tremendous happens after surgery. Recovery is quite painless, compared to other types of surgery.

Patient's Query

Thank you doctor,

Last question. Do you know anything about brain implant technologies?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. Regarding brain implants, they are electronic devices put on the surface of the brain, used to stimulate that part of the brain. They are mini-invasive surgery with low pain after surgery. They are quite safe. In this regard, there are some different types of implants: 1. Deep brain stimulation in different parts of basal ganglia, used for movement disorders. 2. Vagal nerve stimulation used in epilepsy.

Patient's Query

Hi doctor,

Thank you so much. How can I contact you via call?

Answered by Dr. Aida Abaz Quka

Hi,

Welcome back to icliniq.com. I am glad to have been helpful to you. You can contact the customer care team for further details about consulting me through call.

Patient's Query

Thank you doctor,

If someone was to get a neural implant put in what is the surgery or procedure like to remove it? Also, are these implants visible with any type of scan prior to surgery?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. Usually, removal is like implantation procedure. The pain is minimal as this is mini invasive surgery (stereotactic). But the main risks are bleeding risk and infection risk. The device can be detected through brain computed tomography (CT) scan or Magnetic resonance imaging (MRI). If the procedure is done by a specialist in the field, the rate of complications is less than 5 %.

Patient's Query

Hello doctor,

How does one go about getting a computed tomography (CT) scan or an Magnetic resonance imaging (MRI)?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. Regarding your concern, I would explain that a neurologist should order these two tests. Usually, a brain magnetic resonance imaging (MRI) is a better test with a higher resolution for basal ganglia. In addition, it is a better test to examine for movement disorders and study the region of deep brain stimulation. While the brain computed tomography (CT) scan can be performed after the procedure, as it takes a short time to complete, lower cost, and helps exclude possible bleeding as a complication of the process. You should discuss with your attending physician about those tests.

Patient's Query

Hello doctor,

Does both magnetic resonance imaging (MRI) and computed tomography (CT) scan detect a brain implant correctly?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. Yes, both these tests can detect a brain-deep stimulation device. There is no consensus on which test is best after a deep brain stimulation device is implanted. They can help determine the device's position and possible complications like brain hemorrhage. Different centers use different imaging methods (computed tomography (CT) or magnetic resonance imaging (MRI)).

Patient's Query

Hello doctor,

Is it possible to get a brain computed tomography (CT) scan or an magnetic resonance imaging (MRI) on your own without a prescription from a neurologist?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. Yes, this may be possible in a private hospital or private clinic, as you pay for the tests you want to perform. But usually, it is necessary to consult a doctor before (general practitioner, ear, nose, and throat (ENT) specialist, or neurologist) doing these procedures.

Patient's Query

Hello doctor,

Can I just walk in and ask for one of those tests?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. In a private clinic or hospital, you can request one of these tests and do that test. In many countries, you can do this. Anyway, you should discuss with your doctor about this, because different countries have different health systems.

Patient's Query

Hello doctor,

What do brain implant devices look like on a brain computed tomography (CT) scan or an magnetic resonance imaging (MRI)?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. A brain implant device looks like a black spot on the magnetic resonance imaging (MRI) or a white spot on a computed tomography (CT) scan. This is because these are what the electrodes look like. But some artifacts, like lines, are also created by the MRI or CT scan machine.

Patient's Query

Hello,

Welcome back to icliniq.com. As far as circumference, how big are neural implants? Just want to know how visible they are. Also, when I get scanned, will the doctor give me a copy of the magnetic resonance imaging (MRI) or the computed tomography (CT) scan for my records? If so, would I be able to share them with you here?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. They are of millimetres in diameter, so small. They may be seen less than 0.39 inches diameter. I would be glad to review those test reports as soon as you will be able to upload them.

Patient's Query

Hello doctor,

So you are saying that they can be a little as a millimeter and as large as a centimeter.

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. No, I mean some millimetres up to one centimeter, depending on the device and the technique used.

Patient's Query

Hello doctor,

Would you be able to give me a referral or a script to get these two tests done?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. Unfortunately, this site aims to guide patients through the right path to diagnosis and treatment options. We are not able to make prescriptions for tests or medications. We can only suggest to you what to do and discuss it with your doctor about it.

Patient's Query

Hello doctor,

Do they have telemedicine for attention deficit hyperactivity disorder (ADHD)?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. I do not really understand your question. Attention deficit hyperactivity disorder (ADHD) is a chronic disorder, not an emergency. Telemedicine can be used to consult with a doctor online for a second opinion. It can be done for ADHD patients, as for other disorders.

Patient's Query

Hello doctor,

What does a brain implant look like in an ultrasound?

Answered by Dr. Aida Abaz Quka

Hello,

Welcome back to icliniq.com. Regarding your concern, I would explain that the brain is not visible in normal ultrasound because it is inside the skull. But, it can be visible in transcranial ultrasound, a special type of ultrasound that uses specific regions of the skull where the bones match each other. Brain implants are hyperechogenic and show acoustic shadows. A brain computed tomography (CT) scan is a more accurate tool to examine brain implants.

Same symptoms don't mean you have the same problem. Consult a doctor now!
