Symptoms of a Stroke

F.A.S.T. Stroke Symptoms

Ramin Rak breaks down the F.A.S.T. stroke symptoms.

Ramin Rak practices his advanced knowledge of microneurosurgical techniques at Neurological Surgery P.C. on Long Island.

Here, he specializes in awake craniotomies, spinal surgeries, skull-based surgeries, and treatment of tumors.

More information on these complex procedures can be accessed through his Pinterest page.

A stroke is caused by a disturbance in the blood supply and results in the loss of function.

An ischemic stroke is caused by a clot that obstructs blood flow, while a hemorrhagic stroke is a result of a rupturing blood vessel. A transient ischemic attack can also occur, which is essentially a mini stroke caused by a temporary clot. Both types of strokes are extremely serious, as they are the number four cause of death, and the leading cause of adult disability in the United States.

According to strokeassociation.org, F.A.S.T is an easy way to remember the sudden signs of a stroke:

  • Face Drooping- If one side of your face is drooping or your smile is uneven, it could indicate a stroke.
  • Arm Weakness- When one arm is weak, numb, or drifts downward when your arms are raised, seek immediate medical attention.
  • Speech Difficulty- If someone is struggling to form words or unable to repeat a simple sentence, a stroke may be the cause.
  • Time to call 911- If you are experiencing any of these symptoms, call 911 immediately, even if the symptoms go away.

Beyond these core symptoms, a person may also present numbness of the leg, arm or face; trouble seeing; an unexplained sudden, severe headache; dizziness or loss of coordination; and confusion or trouble understanding.

Quick stroke treatment can save lives, so it is crucial to seek immediate medical attention if you have shown any of the above symptoms. After a doctor makes a diagnosis, they will begin a treatment plan specific to the cause of the stroke.

Symptoms of Brain Aneurysms

Brain Aneurysm

Brain Aneurysms are one of many conditions that Dr. Ramin Rak treats.

Ramin Rak is a Board Certified neurosurgeon with Neurological Surgery. P.C.

He is highly skilled at treating a number of conditions involving the brain and spine, including Aneurysms. A brain aneurysm is a weak area in the artery wall, comparable to a thin balloon. Over time, blood flow pounds on these weakened areas and the artery wall becomes thinner and swells outward.

Statistics from the Brain Aneurysm Foundation show that an estimated 6 millions people in the United States have an un-ruptured brain aneurysm, or 1 in 50 people.

Certain factors can increase your risk of developing an aneurysm, including aging, hardening of the arteries, family history, race, gender, high blood pressure, and smoking.

Unfortunately, brain aneurysms that are un-ruptured are typically asymptomatic since they are so small in size.

Larger un-ruptured aneurysms, however, can press on the brain or nerves, causing various neurological symptoms such as:

  • Localized Headache
  • Weakness and numbness
  • Blurred or double vision
  • Pain above and behind eye
  • Difficulty speaking
  • Dilated pupils

When a brain aneurysm ruptures, it causes bleeding into the subarachnoid space, otherwise known as a subarachnoid hemorrhage.

As the blood seeps into the skull, sudden symptoms can occur all at once that require immediate medical attention. These include:

  • Loss of consciousness
  • Vomiting/Nausea
  • Stiff Neck
  • Sensitivity to light
  • Dizziness or sudden trouble walking
  • Sudden numbness and weakness
  • Sudden severe headache
  • Sudden blurred or double vision
  • Drooping eyelid
  • Sudden pain above/behind the eye or difficulty seeing
  • Sudden change in mental status or awareness
  • Seizure

A ruptured brain aneurysm can cause a stroke, brain damage, or even death.

Approximately 15% of patients that suffer from subarachnoid hemorrhage die before reaching the hospital, while four out of seven who recover are faced with disabilities. Though the statistics are grim, Dr. Ramin Rak and the skilled surgeons at Neurological Surgery, P.C. are able to administer advanced surgical treatment to provide patients with the best care possible.

Stereotactic Radiosurgery

Hi all, Ramin Rak back again with another blog post about my work as a neurosurgeon with Neurological Surgery, P.C. I specialize in treating disorders related to the brain and spine, and frequently treat benign and malignant brain tumors with the NSPC Brain Tumor Center.

One way that I treat these tumors is by performing stereotactic radiosurgery.

Stereotactic radiosurgery is a form of radiation therapy where high-powered x-rays are focused on a small area of the body where a tumor is located.

This procedure not only does a better job of targeting the specific area where the tumor is located but also is safer because it is less likely to affect surrounding tissue.  Certain types of stereotactic radiosurgery, such as the Cyberknife and Gamma Knife procedures, require the use of a fitted face mask or frame that goes over the scalp.

Despite its name, stereotactic radiosurgery is not a surgical procedure.

This treatment is intended to shrink tumors solely by using targeted radiation. I recommend this option for individuals with small, deep tumors that would be hard to remove during surgery as well as individuals who are unable to have surgery, such as the sick or elderly.

During this procedure, the patient will lie down on a treatment table, which then slides into the treatment machine.

Radiation is applied in sessions that last between 30 minutes and one hour. Usually no more than five treatment sessions are necessary, but the exact number of needed sessions will be determined based on the type and size of the tumor.

While it is most common for stereotactic radiosurgery to be used for non-surgically addressing tumors, it can also be used following surgery to remove abnormal tissue left behind following surgery.

If you have any questions about stereotactic radiosurgery or other complex brain and spine procedures, check to see if I have addressed them on my Quora.

Thank you for reading,

Microdiscectomy

Hi all, Ramin Rak here with another blog post about the complex neurosurgical procedures I complete at Neurological Surgery, P.C.

I specialize in the completion of surgeries meant to treat ailments affecting the brain and spine. In previous blog posts I have discussed my work with the NSPC Brain Tumor Center and spinal procedures such as Spinal Fusion and the X-Stop Procedure. One spinal procedure that I have not written about is a microdiscectomy.

When a patient complains of leg pain I can use magnetic resource imaging (MRI) or a computer tomography (CT) scan to determine if the patient has a herniated disc.

Using these results, I then decide whether or not a microdiscectomy will relieve the patient’s symptoms.

This spinal procedure is primarily used to treat leg pain, specifically leg pain arising from a herniated lumbar disc. Compression or impingement on the nerve root, defined as bone colliding with or striking the nerve root, will cause considerable leg pain. A microdiscectomy is used to relieve leg pain, and in many cases the patient will feel relief immediately after completion of surgery.

When completing a microdiscectomy, I examine the disc and nerves under a high powered microscope so that I only need to make a small incision.

By using this microneurosurgical technique instead of performing a discectomy, patients experience a much smaller recovery time because there is less tissue damage.

After the incision is made, I move the back muscles off of the bony arch (lamina) of the spine. I am then able to enter the spine by removing a membrane over the nerve roots and visualize the nerve using operating glasses. Once herniated disc material is removed, the procedure is complete.

For more information about the types of spinal procedures I have completed, take a look at my other blog posts or view some of the surgical videos I have uploaded to Vimeo by clicking here.

Kyphoplasty Surgery

Hello again, my name is Ramin Rak and I am writing this post to share information about another complex spinal procedure that I perform at Neurological Surgery, P.C.: Kyphoplasty Surgery.

I am one of six Neurological Surgery, P.C. neurosurgeons who performs kyphoplasty surgery. The others are:

  • Dr. Stephen D. Burstein
  • Dr. William J. Sonstein
  • Dr. Benjamin R. Cohen
  • Dr. Artem Y. Vaynman
  • Donald S. Krieff, D.O., F.A.C.O.S.

I perform kyphoplasty surgery in order to reverse spinal compression caused by a spinal bone fracture.

Individuals who experience compression lose vertebral body height and experience intractable pain. Fortunately kyphoplasty surgery removes pain relief roughly 48 hours after completion of the procedure, and patients can leave the hospital on the same day the procedure is completed.

Once the patient has been sedated, I make a small incision in the patient’s back so that I can insert a narrow tube-like needle into the fractured vertebral body.

I then use an imaging technique called fluoroscopy, which uses x-rays to provide a real-time moving image of the patient’s spinal structure, to guide the needle into the fractured area. Once a path has been made to the spot of the fracture, I insert a balloon into the tube, guide it to the vertebrae, and then slowly inflate it. The inflated balloon elevates the spinal structure, which restores vertebral body height. Next I remove the balloon and fill the cavity created by the balloon with a cement-like material that hardens quickly and stabilizes the spinal structure.

The entire procedure takes roughly one hour per affected vertebra and following conclusion of the procedure, the patient is observed in the recovery room until my doctors determine that he or she can leave.

This is how I complete kyphoplasty surgery at Neurological Surgery, P.C.

Learn more about how I complete this procedure by reaching out to me on Doctor’s Hangout.

Schwannoma

Thank you for visiting my blog. My name is Dr. Ramin Rak and I am a surgeon with Neurological Surgery, P.C.

I specialize in treating complex spinal and brain complications at the eleven different medical facilities affiliated with Neurological Surgery, P.C. and I am a member of the organization’s Neurosurgeon Brain Tumor Team.

The Brain Tumor team includes an Endovascular Neuroradiologist, two Neuro-oncologists, a Neuropsychologist, myself, and seven other neurosurgeons:

  • Dr. Michael H. Brisman, M.D., F.A.C.S.
  • Dr. Jeffrey A. Brown, M.D., F.A.C.S.
  • Dr. Lee Eric Tessler, M.D., F.A.A.N.S.
  • Dr. Alan Mechanic, M.D., F.A.C.S.
  • Dr. Robert N. Holtzman, M.D.
  • Dr. Vladimir Dadashev, M.D.
  • Dr. Gerald M. Zupruk, M.D., F.A.A.N.S.

The rest of the Brain Tumor Team and I work to treat brain tumors and complications caused by tumors, including gioblastoma, medulloblastoma, acoustic neuroma, and schwannoma.

Schwannoma is a homogenous tumor that is made up entirely of Schwann cells, which conduct nervous impulses along axons, provide trophic support for neurons, and support nerve development and regeneration.

The tumor cells are always on the exterior of the nerve though the tumor itself can cause nerve damage by pushing the nerve aside or into bone. Schwannomas become malignant in less than 1% of cases and are slow growing, but should still be treated if weakness numbness, pain or other symptoms are seen.

The Brain Tumor Team at NSPC uses surgery or stereotactic radiosurgery to treat schwannomas with radiosurgery being an option when the tumor is located in the head or spine.

The most common treatment is stereotactic radiosurgery, or the use of a machine called the Gamma Knife to focus high-powered x-rays at the spot of the tumor. Between 80 and 90% of the patients who opt instead to have surgery report that pain, weakness, and numbness disappears following the procedure.

This is an example of a schwannoma. It typically has dense areas called Antoni A (black arrow) and looser areas called Antoni B (blue arrows). The cells are elongated (spindle shaped) and the nuclei have a tendency to line up as you see here in the Antoni A area. (via ucsf.edu)

NSPC Brain Tumor Center

NSPC Brain Tumor Center with Ramin Rak

Hi all, Ramin Rak here with another blog post about my work as a neurosurgeon.

I am affiliated with Neurological Surgery, P.C., New York’s private largest neurosurgical group. One of the resources that Neurological Surgery, P.C. uses to provide better treatment is the Long Island Brain Tumor Center (their official website is located here).

I am one of the neurosurgeons who is part of the Neurosurgeon Brain Tumor Team, along with:

  • Dr. Michael H. Brisman, M.D., F.A.C.S.
  • Dr. Jeffrey A. Brown, M.D., F.A.C.S.
  • Dr. Lee Eric Tessler, M.D., F.A.A.N.S.
  • Dr. Alan Mechanic, M.D., F.A.C.S.
  • Dr. Robert N. Holtzman, M.D.
  • Dr. Vladimir Dadashev, M.D.
  • Dr. Gerald M. Zupruk, M.D., F.A.A.N.S.

The Brain Tumor Team also includes an Endovascular Neuroradiologist (Dr. John Pile-Spellman, M.D.), a Neuropsychologist (Dr. Gad E. Klein, Ph. D.), and two neuro-oncologists (Dr. Paul Duic, M.D. and Dr. Jai Grewal, M.D.).

The Long Island Brain Tumor Center focuses on treating conditions like acoustic neuroma, schwannoma, ependymoma, astrocytoma, and other ailments related to brain tumors.

A brain tumor occurs as a result of uncontrolled cell division in the brain itself, glial cells, lymphatic tissue, the cranial nerves, brain envelopes, the skull, pituitary and pineal gland, or can even be spread from cancer located in other areas. Symptoms of a brain tumor include phantom odors and tastes, while onset symptoms like an epileptic seizure in a patient with no history of epilepsy or sudden intracranial hypertension have also been observed.

The team of neurosurgeons within the Long Island Brain Tumor Center diagnoses tumors using computed tomography (CT) and magnetic resonance imaging (MRI) mapping techniques.

Tumors must be investigated before a diagnosis and treatment options can be determined, but the good news is that not all brain tumors are cancerous.

Take a look at my other blog posts to find out how I use techniques like Gamma Knife, and CyberKnife procedures to treat brain tumors without surgery.

Spinal Fusion

Good afternoon, and thank you for visiting my blog.

My name is Dr. Ramin Rak and I am a neurosurgeon with Neurological Surgery, P.C. Though I primarily specialize in techniques that treat brain injuries and tumors (like the Cyber Knife and GammaKnife procedures that I spoke of in earlier blog posts), I also complete complex procedures intended to alleviate spinal conditions. Last week I detailed my use of the X-Stop Procedure for individuals suffering from back pain and this week I will talk about my technique for treating a condition called spondylolisthesis.

Spondylolisthesis occurs when a damaged or fractured joint allows a vertebra to slip forward and pinch a nerve joint in the spine.

This pain will travel all the way down to the patient’s legs via the sciatic nerve. Surgeons perform a spinal fusion to treat this condition and alleviate patient pain. At Neurological Surgery, P.C. I am a member of the Spinal Fusion Team along with:

  • William J. Sonstein, M.D. F.A.C.S.
  • Benjamin R. Cohen, M.D. F.A.C.S.
  • Artem Y. Vaynman, M.D. F.A.A.N.S.
  • Donald S. Krieff, D.O. F.A.C.O.S.

My team and I perform the spinal fusion procedure to treat intractable back pain by fusing two or three lumbar spine segments.

We start by removing the lamina, which is the portion of the spine that covers the problematic vertebra. Next, the Spinal Fusion team removes any piece of bone that is pinching the vertebra, relieving any pressure and pain. A bone graft is then performed, which fuses together the two spine segments around the vertebra. Finally, screws and rods are used to hold the spine in place while the grafts heal. Once the grafts heal, they will fuse into place and keep the discs from slipping and causing future complications.

Learn more about the spinal fusion team and the PLIF (posterior lumbar interbody fusion) or spinal fusion procedure by clicking here to view a video demonstration on NSPC’s website. Stay up to date on my other neurosurgical techniques when you follow me on Twitter.

The X-Stop Procedure

Hello all, Dr. Ramin Rak here with another blog post.

Many of my posts have focused on complex neurosurgical techniques that I have used and still use, but I also specialize in completing complex spinal surgeries for individuals suffering from back pain. One of my specialties is the X-Stop Procedure, and I am one of only seven surgeons at Neurological Surgery, P.C. who complete this procedure. The others are Dr. Stephen D. Burnstein, Dr. William Sonstein, Dr. Benjamin Cohen, Dr. Artem Vaynman, Dr. Alan Mechanic, and Dr. Donald Krieff.

The X-Stop Procedure involves the insertion of a titanium implant called the X-Stop Spacer.

The spacer is placed in order to treat back pain and leg pain caused by lumbar spinal stenosis (LSS). LSS takes place when space between the vertebrae is reduced, as this lack of space causes bone or tissue to come in contact with the spinal nerve. Individuals who are suffering from LSS find relief when seated or bending over because these positions open up space between the vertebrae. The X-Stop Procedure draws inspiration from this concept, using the X-Stop Spacer to lift the vertebrae off of the pinched nerve and provide long-term relief.

X-Stop Spacer

A diagram of the X-Stop Spacer following placement.

I complete the minimally invasive X-Stop Procedure by surgically inserting the X-Stop Spacer between two bones in the back of the spine; usually L3/4 or L4/5.

The surgical site is located between the posterior spinous processes, which is an area you can feel for yourself by running a finger along your spine. The X-Stop Spacer stays in place by working with one’s natural spinal anatomy, which means that the procedure is completed without using screws or needing to be attached to bones or ligaments.

The X-Stop Procedure takes between 50 and 90 minutes, and patients are able to walk around shortly after the anesthesia wears off. Patients see results immediately after the procedure, as they will no longer experience back pain when standing or walking around.

Learn more about the X-Stop Procedure by visiting their website, or leave a comment below if you still have questions.

Brain Tumor Walk and Neurological Surgery, P.C.

Greetings!

My name is Dr. Ramin Rak and this is my first blog post. I am a Neurological Surgeon and I work for Neurological Surgery, P.C., which is the largest neurosurgical group in New York. I am also the Chief of Neurosurgery in the Neurological Surgery, P.C. office located in Rockville Centre, New York.

I am writing this blog post because some of my colleagues at the Long Island Brain Tumor Center (part of Neurological Surgery, P.C.) are sponsoring the second annual “Run for Rob” walk this Sunday, October 28th.

This annual fundraiser was created to honor the memory of Dr. Robert Bernstein, an obstetrician and gynecologist. At the time I wrote this blog, “Run for Rob” had already raised over $50,000 to fund research for brain cancer. The walk will take place at Bethpage State Park in Farmingdale, New York, with registration beginning at 9 AM. It is not too late to make a donation; simply head to the “Run for Rob” website to make a general donation or to donate to a specific team.

“Run for Rob” is organized by Voices Against Brain Cancer!

This organization was established in loving memory of Gary Lichtenstein, a 24-year old options trader at Wolverine Trading who lost his battle with brain cancer on October 1st of 2003. Gary’s family started “Voices Against Brain Cancer” to advance scientific research, increase awareness in the medical community, and to support patients and family members affected by this terrible disease. Funds raised by Voices Against Brain Cancer pay for research at Universities such as:

  • Columbia
  • Cornell
  • Duke
  • Harvard
  • John Hopkins
  • MD Anderson
  • Memorial Sloan Kettering
  • Yale

Voices Against Brain Cancer also sponsors a number of support groups including the New York Non-Malignant Brain Tumor Support Group, and support groups for family members and caregivers of brain cancer patients.

If you are able to donate to “Run for Rob,” your donation will help fund research that will uncover new methods of treating brain tumors.

Thank you for time, and be sure to stop by again to learn more about my work with Neurological Surgery, P.C.
