Deep Brain Stimulation

Dr. Badih Adada, a neurosurgeon at Cleveland Clinic Florida and a former medical director and professor, possesses more than two decades of experience in a range of neurological specialties. Among these fortes is a sound understanding of movement disorders and deep brain stimulation, and Dr. Badih Adada carries out related procedures for patients suffering from epilepsy and Parkinson’s disease.

Deep brain stimulation (DBS) is one surgical option for the treatment of Parkinson’s disease, and can improve symptoms–tremors, rigidity, and difficulty walking, for instance–by blocking electrical signals stemming from certain parts of the brain. The procedure is generally reserved for patients whose symptoms have not responded to medication.

Prior to the surgery, the patient is given an MRI, the image from which helps the neurosurgeon pinpoint the precise spot in the brain requiring stimulation. The location is most often within the thalamus, subthalamic nucleus, or globus pallidus.

The DBS implantation device is made up of three parts: A lead or electrode is implanted into the brain; it is then connected to an IPG (implantable pulse generator) via an insulated wire “extension” that passes beneath the skin, along the shoulder, neck, and head.

DBS procedures do not cause any significant permanent changes to the brain. If the implant results in negative side effects, or the patient chooses to end the treatment for any reason, the IPB can be removed, halting stimulation.


Arteriovenous Malformations – A Basic Introduction

Dr. Badih Adada, a member of the surgical team at the Cleveland Clinic, has earned widespread recognition for his expertise in neurosurgery. Dr. Badih Adada performs extremely complex procedures, such as those that treat arteriovenous malformations.

In a healthy brain, arteries deliver fully oxygenated blood, and veins return blood to the heart after cells have used the oxygen that they need. In patients with an arteriovenous malformation (AVM), however, there is a tangle of blood vessels, called a nidus, causing the blood to move directly from arteries to veins. The veins then carry fully oxygenated blood back to the heart, and the tissues do not receive the oxygen they need to survive.

Without a sufficient supply of oxygen, brain tissues can suffer and experience cell death. The condition can also lead to the weakening of blood vessels, which can burst and cause dangerous, life-threatening hemorrhages.

Treatment most often involves surgery, endovascular embolization or focused radiation therapy, depending on the location and type of the AVM. Surgery requires the removal of the central area of the AVM, for smaller AVMs, focused radiosurgery is sometimes enough to permanently close up the affected vessels.

Signs of Brain Aneurysm

Dr. Badih Adada is an accomplished neurosurgeon who has performed more than 4,000 procedures throughout his 14-year career. Treating patients in Florida, Dr. Badih Adada has performed various neurosurgical procedures to help treat conditions such as epilepsy, Parkinson’s disease, and brain aneurysms.

According to the American Stroke Association, between 1.5 and 5 percent of people will be found to have a brain aneurysm at some point in their lives. Due to the serious nature of this condition, it’s important to recognize the symptoms in the event you or a loved one is in the precarious position of having to deal with an aneurysm.

According to the Brain Aneurysm Foundation, an aneurysm that has not ruptured can be hard to diagnose, because it produces little to no symptoms. If the aneurysm is large enough, however, certain indicators may present themselves. The following symptoms could be indicative of an aneurysm.

-Headache in only one spot.
-Pain above or behind the eye.
-Unusual pupil dilation.
-Blurry or double vision.
-Weakness and/or numbness.
-Slurring of speech.

Additionally, if the aneurysm has ruptured, blood can spill into the areas around the brain, also causing a severe headache.

Seek the immediate attention of a qualified medical professional if these symptoms present themselves. A physician can accurately diagnose whether an aneurysm is present and work through the next steps that need to be taken.

Complex Brain Tumors: Definition, Treatment, and Technologies

Accomplished neurosurgeon Dr. Badih Adada has performed more than 4,000 neurosurgeries since becoming a surgeon 14 years ago. Currently working in Florida, Dr. Badih Adada has performed neurosurgical procedures that help treat conditions such as epilepsy, Parkinson’s disease, and brain aneurysms. He has special training in the treatment of complex brain tumors.

Complex brain tumors are tumors that are challenging to treat surgically. Their complexity may be due to their location within the brain or the effects they have on an individual’s cognitive functions. Statistics from the American Brain Tumor Association (ABTA) indicate that upwards of 78,000 Americans will be diagnosed with either malignant (cancerous) or benign (non-cancerous) primary brain tumors this year. ‘Primary’ refers to tumors that form in the brain and stay in the brain. Both malignant and benign tumors can be classified as ‘complex.’

People with complex brain tumors have several options for treatment. They can undergo surgery to have the tumor removed, or they can opt for different forms of radiation therapy. The latter is often done in conjunction with surgery for tumors that can’t be eradicated with surgery alone. New technologies such as brain-mapping and Diffusion Tensor Imaging (DTI) have been instrumental in allowing neurosurgeons to identify and precisely locate brain tumors and to formulate a plan of action for removing them.

Since 2008, board-certified neurosurgeon Dr. Badih Adada has treated patients at the Cleveland Clinic in Weston, Florida. An involved medical professional, Dr. Badih Adada trains fellow neurosurgeons around the globe and maintains memberships in several organizations, including the American Association of Neurological Surgeons (AANS).

In its efforts to advance the specialty of neurological surgery, AANS holds a variety of educational events throughout the year. The organization recently held its largest gathering, the AANS Annual Scientific Meeting, from April 30 to May 4, 2016, in Chicago.

Neurosurgeons and other medical professionals from around the world attended the five-day event to hear from world-class speakers and take part in a scientific program comprising seminars, symposia, and practical clinics on a range of topics related to neurological surgery and care. Outside of the learning activities, attendees at the 84th AANS Annual Scientific Meeting had the opportunity to network with their peers at several social events and browse the latest medical products and services from more than 200 exhibiting companies.

AANS will hold its next Annual Scientific Meeting April 22-27, 2017, in Los Angeles. For more information, visit

Neurological Conditions – Parkinson’s Disease

Parkinson’s Disease

In his capacity as neurosurgeon at the Cleveland Clinic in Weston, Florida, Dr. Badih Adada provides surgical care, including deep brain stimulation for patients challenged by Parkinson’s disease. Before establishing himself in medicine, Dr. Badih Adada completed his residency in neurosurgery at the University of Montreal.

Parkinson’s is a disease that impacts movement, and has no known cause and no cure, though researchers have developed effective therapies to manage the condition as it progresses. When a patient develops Parkinson’s, it means that neurons have begun to die in the substantia nigra, a part of the brain. Many of these neurons are important, as they provide the brain with a molecule that regulates movement. As the neurons die, less of this molecule is released, giving rise to movement difficulties like tremors and balance issues in patients.

Deep brain stimulation is one of many innovative treatments for Parkinson’s disease, which involves surgery to insert electrodes into the brain that stimulate specific neural regions. The stimulus in turn blocks tremor-causing signals. Interestingly, medical researchers do not yet understand the mechanisms that make deep brain stimulation effective in treating Parkinson’s-related tremors.

Brain Tumors – Origins and Grading

Brain Tumors

As a board-certified neurosurgeon, Dr. Badih Adada has performed over 4000 operations, including highly complex procedures to address arterio-venous malformations, aneurysms, and tumors. Presently, Dr. Badih Adada treats patients as neurosurgeon with the Cleveland Clinic Florida.

When examining brain tumors, doctors use special terms to understand the origin and progression of the disease. For example, it is important to determine whether or not brain tumors begin in the brain or spread to the brain from other parts of the body. In the case of the former, doctors refer to the tumor as primary, and in the case of the latter, they refer to the tumor as secondary or metastatic. Depending on the origins of the cancer, different therapies may be appropriate.

Moreover, not all brain tumors are cancerous, or malignant. If a tumor is not malignant, it is considered benign. In the event a brain tumor is malignant, doctors can grade the tumor on a scale from one to four, based on the appearance of its cells. Grade one tumor cells look almost normal and tend to grow sluggishly, while grade four tumor cells look quite strange and tend to grow aggressively.
