Deep Brain Stimulation

What is Deep Brain Stimulation?

DBS involves surgically implanting tiny electrodes into the brain and connecting them to a small pacemaker-like device (with a programmable battery) that has been implanted into the chest wall. The electrodes deliver tiny electrical signals that calm abnormal brain signals, alleviating disabling symptoms, such as tremors, and restoring function to the patient.  

We frequently treat patients with these diagnoses: 

Essential Tremor

DBS is considered when patients with persistent and severe tremor are not receiving significant benefits from medications or the side effects are too severe.

Parkinson's Disease

DBS is considered when a patient has idiopathic Parkinson’s disease, and one of the following issues:

  • Debilitating hand or leg tremor that fails to respond to medications
  • Idiopathic Parkinson's disease with continued good benefit from treatment with medications, but with frequent return of disabling rigidity, slowness of movements, tremor due to "on-off" fluctuations or excessive uncontrollable movements called “dyskinesia”
  • Idiopathic Parkinson’s disease but failure to tolerate all Parkinson’s medications due to severe side effects


DBS is considered when a patient has significant debilitating symptoms of primary dystonia and has failed to respond to oral medication, botulinum toxin therapy (Botox) and other treatment modalities.

Obsessive Compulsive Disorder

DBS is considered when a patient has severe OCD symptoms that have lasted for more than five years and have failed to respond to medication and cognitive therapies.

Steps to becoming a DBS candidate

If you are interested in becoming a candidate for deep brain stimulation at Ohio State’s Center for Neuromodulation, you must have a physician referral. Contact your healthcare provider for an initial evaluation and referral to Ohio State’s Center for Neuromodulation. Your healthcare provider will complete a referral form and submit it to our center. You will then be scheduled to receive a comprehensive screening and evaluation by our multidisciplinary team.

Screening and Evaluation

Each patient who is referred to Ohio State’s Center for Neuromodulation for a DBS consultation will be scheduled for a comprehensive screening and evaluation to determine the likelihood of a successful response. Here are the steps involved in the screening and evaluation:

  • You will receive an evaluation with a movement disorder neurologist or psychiatrist and functional neurosurgeon to assess various aspects of your disease, symptoms, progression, previous treatments and overall health.
  • You will have brain imaging performed and reviewed by our neuroradiologist.
  • You will have a comprehensive evaluation by a neuropsychologist. The neuropsychological testing helps to better understand your cognitive (thinking, memory, concentration, attention) status and provides a baseline for the team to monitor you over time.
  • Our team has a detailed discussion with you and your family about surgery goals, expectations, benefits and side effects.

Once these evaluations are completed, we discuss our findings as a team and make a final recommendation regarding surgery and other therapies, such as further medication adjustments and an individual rehabilitation program.

We work closely with you, your family members, your caregivers and your referring physicians to develop a comprehensive and holistic care plan.

If you are considering DBS, it is important to have realistic expectations about what symptoms may or may not improve. Additionally, your family and support structure need to be in place to help you with follow-up care and appointments.  

Spinal Cord Stimulation

What is Spinal Cord Stimulation?

Spinal cord stimulation involves electrical stimulation of the spinal cord to interrupt pain signals from the spinal cord to the brain. It is a proven, safe and effective therapeutic approach for managing chronic pain of the neck, back, arms and legs, which may occur following spinal surgery. SCS uses a medical device similar to a pacemaker, which is placed beside the spinal cord, to deliver mild electrical impulses before pain signals arrive. Instead of pain, patients feel a tingling sensation from the neurostimulation in areas where the pain is felt. 

Who should consider SCS?

SCS can benefit you if you have chronic pain of the neck, back, arms and legs occurring as a result of spinal surgery. Some of the conditions treated with SCS include:

  • Failed back surgery syndrome
  • Post-laminectomy pain
  • Peripheral neuropathy
  • Complex regional pain syndrome (also known as reflex sympathetic dystrophy) 

You may want to consider SCS when:

  • Other treatment options have failed to adequately provide pain relief
  • Your doctor understands what is causing your chronic pain
  • Further traditional surgeries are not recommended
  • You don’t have a serious, untreated dependence on pain medication
  • You have passed a psychological evaluation
  • You don’t have medical issues that would make surgery difficult
  • You have had a successful neurostimulation screening test


Overall benefits of SCS may include:

  • Significant and sustained reduction in back and leg pain
  • Improved ability to function and participate in activities of daily living
  • Fewer oral pain medications
  • Ability to stop the therapy by turning it off or surgically removing the SCS device
  • Ability to adjust the therapy based on pain level
  • With improvements in a person’s pain, the potential ability to participate in other forms of therapy to better manage the pain

How is SCS performed?

SCS is performed in two phases. A “trial” phase is done first to see if you can get pain relief from the device. You are normally discharged within 24 hours after the electrode is implanted, and it stays in place for five to seven days. If there is pain relief, a permanent device is implanted, which requires a surgical procedure and an overnight stay at the hospital.

It is important to know that SCS may reduce but not cure your pain. You may feel a tingling instead of the pain, and it may improve your ability to function.

Patient Stories



Don, a retired artist, was losing control of his hands because of his essential tremor.

"There were things that we just couldn't do anymore."

For an artist, having control of your hands means everything. So when Don, a retired art teacher, started experiencing shakiness in his right hand, it threatened to put his lifelong love on hold. Don was diagnosed with essential tremor, a neurological disorder that causes uncontrollable movement. Trying to ease it with medication, Don and his wife Sandy spent their retirement splitting their time in Sylvania, Ohio and in Florida.

Despite medication, Don's tremor persisted. Soon, not only was painting out of the question, but Don's tremor was becoming so bad it was increasingly difficult for him to do things on his own. Simple things like cutting his food and eating required Sandy's help. The active couple started avoiding social situations and ate in the far corner of their favorite Florida restaurant to avoid embarrassment.

"I was a little apprehensive about surgery."

From the beginning, Don's neurologist recommended he consult with The Ohio State University Medical Center about their successful Deep Brain Stimulation therapy (DBS). DBS is an advanced procedure that involves surgically implanting a battery-operated device, similar to a pacemaker, into the body to deliver electric stimulation to the brain.

Although it sounded impressive, Don was apprehensive and scared of the idea of someone operating on his brain. Instead, the couple decided to keep trying different medications to treat Don's tremor. But after a few years of taking many different combinations of more than 30 medications with no relief in sight, Don realized no pill was going to cure his condition.

"It got to the point where I had to do something."

Don's essential tremor continued to interfere with his quality of life, and it was becoming clear medication wasn't the answer. So the couple followed Don's neurologist's recommendation and went to talk to Ohio State. As soon as they walked into the office, they felt completely at ease with neurologist Dr. Agrawal and neurosurgeon Dr. Rezai, who told the couple they thought Don was the perfect candidate for DBS.

They began testing soon after to make sure of Don's eligibility. DBS requires two surgeries. The first places electrodes into the brain, and the second implants the programmer into the chest. After a few days of assessment, Don was cleared for surgery.

"If I knew then what I know now, I would have done it right away and not put it off."

Don's first surgery lasted less than six hours and was completely pain-free. It required Don to stay awake so they could assess the control of his hand throughout the surgery. Sandy was amazed when someone came out of the operating room halfway through to show off a perfectly sketched drawing Don had made.

Now, Don can control his essential tremor with a click of a button. To stop the shaking, he simply holds the antenna near his chest to turn the programmer on. He returns to Ohio State every six months to see his nurse Shannon, who helps him adjust the programmer's settings. Don's life is back in control. He's back to painting and is looking forward to going to Florida again. What's first on the agenda? Dining right out in the middle of his favorite restaurant.



Before Brenda had deep brain stimulation (DBS), her days centered around controlling her symptoms.

Before Brenda Reams had deep brain stimulation (DBS), her days centered around controlling the symptoms of Parkinson’s disease. Since having DBS surgery, her days now revolve around her interests – church activities and her grandchildren.

Brenda’s symptoms began a decade ago. She noticed more mistakes than normal when she was typing and a weakness in her left hand. The symptoms – leaning, foot dragging and lack of arm swinging when she walked – progressed to include her entire left side. She was diagnosed with Parkinson’s disease. Medication helped ease the symptoms, as long as she adhered to a strict regimen, but her quality of life suffered.

“Eventually, I had to take medication every two hours or the symptoms would become obvious.”

“I was a registered nurse working in a hospital, and it was difficult to stay on top of my medication schedule. I worked hard to compensate for the left-side weakness while I was at work, and was exhausted by the time I got home. I felt like I had no strength or stamina for anything else.”

Brenda quit her demanding nursing job of three decades. To compound that disappointment, she also felt unable to take care of her four grandchildren. “I wanted to do things with them and dote on them. When I couldn’t, I was disappointed in myself,” she says.

“I feel like a different person. I play ball with my grandkids and keep up with them. They mean everything to me.”

After DBS, her situation changed and Brenda perked up physically and emotionally, she says. Brenda learned about DBS after being referred to Dr. Agrawal, a neurologist at The Ohio State University Wexner Medical Center. She watched DVDs about the procedure and became eager to learn if she was a candidate. Comprehensive testing confirmed the surgery could help her condition, and she had the procedure eight months later.

Dr. Rezai, neurosurgeon at Ohio State’s Wexner Medical Center performed Brenda’s DBS surgery, implanting tiny electrodes in her brain and a small pacemaker-like device in her upper chest. Thin wires then connected the device to the electrodes, delivering electrical pulses that blocked the abnormal signals from the brain. Two days after surgery, Brenda was back at home.

“If you met me, you wouldn’t even know I have Parkinson’s disease.”

“When I meet other people who have the disease, I give them copies of the DVDs and encourage them to check out DBS. My time at Ohio State was superb. I dearly love Dr. Agrawal. He is very patient centered.”

Brenda still takes medication to help control her symptoms, but she now takes lower doses less frequently. She is concerned Parkinson’s symptoms may one day travel to her right side, but she’s confident Drs. Agrawal and Rezai will be able to use DBS to help.

“If my left-side symptoms worsen, the doctors can change the programming in the implanted system to improve them. And if I get symptoms on the right side, they can do another DBS procedure,” Brenda says confidently. “I feel like DBS is a miracle, and the doctors’ ability to do this is amazing. I know they will be able to help me control my Parkinson’s disease so my life doesn’t have to revolve around it. I’m a Type A personality. I like being in control of my own body and life.”



Pat started to avoid social situations because of her tremor.

“I was avoiding more and more social situations because of my condition.”

Approximately six years ago, Pat started noticing tremors getting worse in her right hand. She didn’t think it was noticeable and kept it a secret from most people that she knew. But she began having difficulty grooming – doing her hair and putting on makeup. She also had trouble cooking and was no longer going out with friends in groups. “I was avoiding more and more social situations,” Pat explains.

About three years ago, Pat mentioned how the tremors were affecting her life to her family doctor. He started her on some medications. After trying a few different medications without much success, her doctor suggested that she should see a neurologist. “I remember they asked me to sign a form in the hospital and I really didn’t recognize my own writing it was so bad,” Pat relates. “So when I saw my family doctor the next time I said, ‘I guess it’s time to see a neurologist.’”

“I really feel very fortunate and blessed.”

“I really feel very fortunate and blessed that I found Dr. Rezai at exactly the right time … right when I needed him,” Pat says. Dr. Rezai explained in detail about how they would perform the surgery, how long she would be in hospital and what improvements she would likely see after surgery.

She was asleep for part of the surgery, but awake when they needed her to answer questions and perform certain tasks as they tested the device. “It was pretty awesome to be able to be able to write my name, hold a glass, touch my nose and all of these different things right there on the operating room table,” Pat explains. “In fact, I went to wipe away a tear when I wrote my name. And someone said ‘Why is she crying?’” Shannon, the certified nurse practitioner, said, ‘Haven’t you ever heard of tears of joy?’”

“I consider deep brain surgery like a miracle”

After Pat’s surgery, Pat recalls that her friends wanted to do bring meals over and she told them she really didn’t need help because of the tremendous improvements from her surgery. “I was able to eat soup and do everything with my right hand that I haven’t for a long time,” Pat relates. While she has her deep brain stimulation device on all day, she turns it off at night. “First thing when I wake up I turn it on and life is good again,” she says. “Many times I think it’s good that I do turn the device off because it gives me a reality check of what life would be like if I didn’t have the surgery.” Pat adds, “I’d do it again in a heartbeat. It has made such a difference. I just really feeI that I have my life back.” Sometimes when she’s eating a bowl of soup or carrying her coffee cup to the kitchen table, Pat remembers that she couldn’t do these things a year ago. “My friends will tell me it’s either magic or a miracle. And Pat concludes, “To anyone who is thinking of deep brain stimulation, I really consider it like a miracle.”

“It really makes me realize how fortunate I am that I have had the surgery.”

When Pat met recently with her neurologist, Punit Agrawal, DO, she told him,“I am doing great. It has been able six months since my last appointment and it has made such a difference in my life. Everything I go to do I just do naturally now.”

She demonstrated to Dr. Agrawal the amazing difference that DBS has made in her abilities. With the DBS turned off, her tremors are very evident. She can’t touch her nose without great effort and her writing is hardly legible. When the device is turned on, she can easily repeat the same tasks illustrating the effectiveness of DBS. “It makes me realize how fortunate I am that I made the decision to have the surgery.

“I feel as though I have my life back again.”

In retrospect, Pat acknowledges that she was more depressed than she realized because there were so many things she couldn’t do. “Initially, I didn’t think my condition was severe enough to warrant surgery,” she explains. Pat, who is a retired RN, was apprehensive initially about having brain surgery. “What really made all the difference in the world was my trust and confidence in my doctors.”

“Since the surgery, I feel as though I have my life back again,” Pat shares. “It’s probably one of the best decisions I’ve made in my life. I’ve had excellent results. In my estimation, my tremor has improved about 100 percent.”



Rob was shocked by the diagnosis of Parkinson’s at the age of 30.

Rob Reeser was diagnosed with Parkinson’s disease when he was only 30 years old. He’d been married for 10 years and had three children. He was shocked by the diagnosis and disheartened by the likely course of the disease. Last year, he had deep brain stimulation (DBS) surgery at The Ohio State University Wexner Medical Center and says he feels like the clock has been turned back 12 years.

“I feel like I did pre-Parkinson’s. I have my life back, and my kids have their dad back.”

Reeser, now 42, lives in Circleville, Ohio, coaches his 12-year-old daughter’s basketball team and golfs with his son, 16. He plays baseball and basketball, and exercises on a treadmill.

Before DBS surgery, Reeser had severe tremors in his arms and legs, and rigidity (dyskenesis). The symptoms, which began as a severe tremor in his thumb, progressed over a decade.

“I was a municipal clerk. When I could no longer write, I had to quit work.”

“Eventually, I was unable to do activities with my kids. My life changed. I couldn’t do normal things people my age could do. My wife, Deanna, said I acted like I was 60. I tried every medication possible, and they caused the dyskenesia. DBS was my only hope.”

During DBS surgery Reeser could tell the procedure was a success. “Dr. Rezai had me hold a glass of water up to my mouth to see if I could drink. Before, I could only drink through a straw because of my tremors. I easily took a drink from the glass. It felt awesome. I was so excited.”

Dr. Rezai implanted tiny electrodes in Reeser’s brain. Thin wires connect the electrodes to a small pacemaker-like device in his chest wall. The electrodes deliver electrical stimulation to block abnormal signals from the brain that cause the disabling symptoms of Parkinson’s disease.

“If DBS surgery hadn’t been available, my life would revolve around medications,” says Reeser. “People who have Parkinson’s should know things aren’t hopeless. This surgery is the hope.”



Roger’s Parkinson’s disease threatened to end his woodworking hobby.

"It’s my hobby and my passion. I don’t know what I would do if I couldn’t do it anymore.”

Roger Evans has been a woodworker for 40 years, making detailed cabinets and custom furniture. Roger retired from a broadcasting career as a popular radio personality in the Huntington-Ashland area, and woodworking fills his days. That he can still pursue his hobby even though he has tremor-dominant Parkinson’s disease is remarkable.

Without the leading-edge treatment he’s had over the last two years, Roger’s tremors would prevent him from feeding himself, shaving or operating a remote control, much less a power tool. But if you meet him today, you would not even know he has a debilitating tremor disorder. Roger had deep brain stimulation (DBS) at The Ohio State University Wexner Medical Center. This neurological surgical procedure implants tiny electrodes into the brain. The electrodes are connected by thin wires to a small battery-like device that is implanted in the chest wall. The electrodes deliver small electrical signals that calm the abnormal signals that cause the tremors.

Roger had DBS to control tremors on his right side. A year later, when his left side began to be affected by tremors, he had DBS to control that side. A single device in Roger’s chest controls both sides.

“It was immediate, and I was amazed."

The first time his device was activated, Roger watched his right hand go from shaking to still. Both sides of his body are tremor-free now. “It’s not a cure - it’s just symptom control. But it has given me my life back. Before, I couldn’t take care of myself. I didn’t want to be a burden to my wife.”

Roger’s tremors began 15 years ago. They were slight and only in his right hand. He saw several neurologists over the next decade as the condition worsened. He tried medications, but they didn’t control his tremors. The cause went undiagnosed until he saw Dr. Agrawal, neurologist at Ohio State’s Wexner Medical Center two years ago. The Parkinson’s diagnosis hit him “like a kick in the head.”

 “I felt like I’d just been handed a death sentence,” says Roger. “Dr. Agrawal and Dr. Rezai showed me that didn’t have to be the case. The care I had at Ohio State could not have been better, and there was hardly any recovery at all. I wouldn’t have any kind of life without deep brain stimulation.”

 “I know my condition is progressive, so it will get worse. But Dr. Rezai is the top in his field and is doing great things. I’m hoping someday they will find a cure for Parkinson’s.”

Roger showed his gratitude to his care team at Ohio State’s Wexner Medical Center by getting busy in his woodworking shop. “The doctors and nurses all have cutting boards now,” he says. “It’s the least I could do to show my appreciation.”
