CINCINNATI—The University of Cincinnati Neuroscience Institute (UCNI) celebrated its 10th anniversary today by announcing its arrival at a national benchmark with accreditations, certifications, or national association memberships in 13 of 14 important neuroscience specialties.
The accreditations and memberships denote excellence in sub-specialty neurological care and research and are highly coveted by academic health centers throughout the United States.
The UC Neuroscience Institute, first envisioned by John M. Tew, M.D., began with an intention to create a national benchmark in neurological care while leading the advance in humanity’s understanding of the brain. It was established in 1998 by neuroscience specialists at UC Health -- University Hospital, the Mayfield Clinic, and the UC College of Medicine. Initial funding for the venture came from the Health Alliance.
During the 10-year span, the Institute has achieved the following distinctions – all of which are publicly available -- from objective, nationally recognized organizations:
The UC Neuroscience Institute's Alzheimer's Center, its 14th specialty area, is under development.
By comparison, the Cleveland Clinic and Ohio State University have achieved similar distinctions in 4 of these 14 neuroscience specialties; the Mayo Clinic and University of Pittsburgh have achieved 8; Johns Hopkins University has achieved 10; Massachusetts General has achieved 9; and the Barrow Neurological Institute has achieved 5.
The UC Neuroscience Institute is thanking supporters who have played an important role in the Institute’s accomplishments this evening at the new CARE/Crawley Building on the UC Academic Health Center campus.

“In developing the Neuroscience Institute we wanted to create a sense of trust and confidence in our community that would allow people to know that they did not have to go to another place for neurological care,” says Dr. Tew, the Institute’s Clinical Director and a neurosurgeon with the Mayfield Clinic. “We wanted people to know that, whether you have a problem that is simple or complex, you can come to us from all walks of life and know with confidence that we’ll provide you with best care available anywhere in the world.”
The Institute grew with the recruitment of pre-eminent physicians, researchers, and nursing specialists. Today it includes more than 100 faculty members in multiple neuroscience specialties, including neurosurgery, neurology, otolaryngology – head and neck surgery, radiology, emergency medicine, ophthalmology, physical medicine and rehabilitation, and psychiatry. The Institute treats thousands of patients each year, many of whom travel to Cincinnati from around the United States and the world. In fiscal year 2008, the Institute recorded 3,893 inpatient and 35,307 outpatient visits.
“University Hospital is proud to be the medical home for the UC Neuroscience Institute,” says Lee Ann Liska, University Hospital’s Executive Director and Senior Vice President. “We are the region’s primary site of tertiary care for the sickest patients and most complex cases. Our advanced technologies include intraoperative MRI, continuous, 24-hour EEG monitoring, mobile CT scanning, a Level 4 epilepsy monitoring unit, and Lycox monitoring of brain temperature and oxygenation.”
“Patients come to the UCNI because of our terrific team of highly specialized physicians, nurses, and other healthcare providers,” says Joseph P. Broderick, M.D., Research Director at the Institute and Chair of the Department of Neurology. “We have a great passion to provide the best clinical care for those patients. And we share that passion with our referring physicians. But the reason they refer to us is because we have highly specialized physicians. Not just a neurologist, but a neurologist highly trained in epilepsy; not just a neurosurgeon, but a neurosurgeon who does the most difficult spine cases in the world. They also refer to us because we collaborate. We have five weekly subspecialty conferences where the most challenging cases are discussed. And they refer to us because we’re not satisfied with the standard care. Our frustration that we can do better is what fuels our research efforts.”
The Institute comprises seven centers of excellence, which are focused on brain tumors, cerebrovascular disease, epilepsy, disorders of the senses (swallowing, voice, hearing, pain, taste and smell), multiple sclerosis, neurotrauma, and Parkinson’s disease. A center for Alzheimer’s disease is in development.
“The future of the College of Medicine will be based more and more on developing centers of excellence in which we can provide ‘added value’ care, research and education for patients in our region and beyond,” says David Stern, M.D., Dean of the College of Medicine. “The UC Neuroscience Institute has been at the forefront in developing highly differentiated programs that meet our patients’ needs and push the field of neuroscience forward. Whether it is our world-renowned stroke program, or the programs in Parkinson’s disease and multiple sclerosis, or the more recently launched brain tumor program, each of these initiatives has great potential to contribute to reducing morbidity and mortality for patients with neurological disorders in our region.”
Other major accomplishments celebrated by the UC Neuroscience Institute include:
CINCINNATI—The University of Cincinnati has been designated a Morris K. Udall Center for Parkinson’s Disease Research by the National Institute of Neurological Disorders and Stroke (NINDS).
The designation carries with it a grant of $6.2 million over five years, which will enhance research at the UC Neuroscience Institute’s James J. and Joan A. Gardner Family Center for Parkinson’s Disease and Movement Disorders. UC researchers will also be working with researchers at Michigan State University’s College of Human Medicine in Grand Rapids.
Parkinson’s disease is a chronic, degenerative neurological order that affects one in 100 people over the age of 60, the average age of disease onset. Symptoms include tremor, or trembling in hands, arms, legs, jaw and face; rigidity, or stiffness of the limbs and trunk; bradykinesia, or slowness of movement; and postural instability, or impaired balance and coordination.
At present, there is no cure for Parkinson’s disease. A variety of medications, however, can provide relief from its symptoms.
The Morris K. Udall Centers of Excellence Program, named in honor of the former U.S. congressman from Utah who died in 1991 after a long battle with Parkinson’s disease, comprises 14 centers including UC’s. Its goal is to create and foster an environment that enhances research effectiveness in a multidisciplinary setting.
“This is certainly an acknowledgment of the excellence of the program here and the talents of our accumulated science investigators,” says Tim Collier, PhD, Director of the Udall Center at UC. “And because community support is a factor in center designation, it’s also an acknowledgment of the generosity of the citizens of Greater Cincinnati and the Tristate region.”
Funding from the Udall Center designation will support a number of research projects, including research by Collier into progenitor cells, or adult stem cells, and how they might promote repair and recovery in the degenerated brain.
Additional research is focusing on such areas as deep brain stimulation, the response of the brain to the standard medication for Parkinson’s disease (levodopa) and the relationship between Parkinson’s disease and depression.
In addition to UC, Udall Centers across the country are Brigham and Women’s Hospital/Harvard Medical School; Columbia University; Harvard University/McLean Hospital; Johns Hopkins University School of Medicine; Massachusetts General Hospital/Massachusetts Institute of Technology; Mayo Clinic, Jacksonville (Fla.); Northwestern University; University of California, Los Angeles; University of Kentucky; University of Miami; University of Pennsylvania School of Medicine; University of Virginia; and University of Washington. The Parkinson’s Disease Data and Organizing Center at the University of Rochester is an associated program.

CINCINNATI--How does a physician approach a complex medical condition that may or may not be what it appears? That is the challenge offered by the bi-monthly Movement Disorders Video Rounds, a collegial, academic exercise at the James J. and Joan A. Gardner Center for Parkinson’s Disease and Movement Disorders at the University of Cincinnati Neuroscience Institute. The video rounds, which feature video of patients with ambiguous or complex diagnoses, are the brainchild of Alberto Espay, M.D., Assistant Professor in the Department of Neurology.
“During video rounds we get together and discuss challenging cases,” Dr. Espay says. “These are patients who have come to us with atypical presentations, and we have had a difficult time diagnosing them. They are not the bread-and-butter presentations for any of the conditions.
“During the sessions we think about these cases from the ground up,” Dr. Espay continues. “We consider the patient, the videotape of the examination, pertinent data and the patient’s medical history. Then we all brainstorm. Of course, the person who is presenting the case has more information, because presumably a number of investigations have already been undertaken to try to determine the diagnosis. And of course, therapy has been delivered to the patient.”
The goal of video rounds, Dr. Espay says, “is to learn one or two things about movement disorders that you didn’t know coming into this session.”
Dr. Espay, who came to UC in 2005, started the video rounds in 2006 as an enjoyable way for physicians and residents to better educate themselves about the spectrum of movement disorders, which is vast and dotted with rarities and exceptions. The field of movement disorders is by its nature highly visual, with patients experiencing a range of symptoms or side-effects related to movement, including balance problems, freezing of gait, stiffness, loss of coordination, tremor, and involuntary movements. Gardner Center neurologists routinely acquire video of patients to preserve a benchmark prior to treatment or disease progression.
Because video rounds are held at the end of the day, and because attendance is voluntary, Dr. Espay offers a little wine and cheese to help the medicine go down. “It’s very informal,” Dr. Espay says. “No one has high brows about this.”
Last year Dr. Espay took the video rounds concept a step further, by inviting the University of Louisville and the Medical College of Georgia and turning it into the Tri-State Movement Disorders Competition, a CME-accredited educational session sponsored by an unrestricted educational grant from TEVA Pharmaceuticals.
During the competition, each team presents two or three cases, which the opposing schools then strive to think through and diagnose. “The test is to show that your thinking process is logical,” Dr. Espay says. “The answer is the diagnosis. It is a nurturing experience for all of us.”
The Gardner Center team triumphed in 2008 and 2009, and Dr. Espay proudly displays the official trophy in his office.
This year’s most difficult case is likely to be submitted for publication as a case study. It involved the diagnosis of a patient who developed a parkinsonian syndrome in her mid-teens. Dr. Espay, who first saw her in her late teens, disagreed with the initial diagnosis of dopa-responsive dystonia because of inconsistent features of her disease, including disease progression and prominent dyskinesias of the face. Although he had seen only one case like hers before, he correctly postulated that she was suffering from a rare condition known as neuronal intra-nuclear inclusion disease (NIID). A brain biopsy eventually affirmed Dr. Espay’s diagnosis. The patient, he says, “became only the sixth reported case of juvenile parkinsonism and only the second presenting in a way that, early on, was indistinguishable from dopa-responsive dystonia, but that eventually revealed other features that were not consistent with that condition.”
Physicians are not the only ones who benefit from seeing video of patients with movement disorders. “All of our patients are videotaped, and we review these videos with them,” Dr. Espay says. “If patients come back three years after their first assessment and wonder what they were like before, we can show them. It’s a great tool for us, and our patients really appreciate this resource.”
CINCINNATI—Around the United States and the world, April is Parkinson’s Awareness Month. A proclamation signed by Mayor Mark Mallory has designated April as Parkinson’s Awareness Month in Cincinnati as well.

CINCINNATI–A $51,000 grant will enable University of Cincinnati (UC) researchers to determine whether sophisticated new imaging technologies can help them achieve pinpoint placement of deep-brain stimulation electrodes in patients with Parkinson’s disease. George Mandybur, MD, a neurosurgeon with the Mayfield Clinic and the UC Neuroscience Institute, is leading the pilot study, which will take place at University Hospital.
Mandybur and his team will use a 3-Tesla MRI scanner with high-resolution sequences, along with diffusion tensor imaging fiber tracking, in an attempt to quickly and accurately predict the size and position of the subthalamic nucleus, a small area deep within the brain. The size and location of the subthalamic nucleus can vary significantly from patient to patient.
Physicians have long known that by stimulating the subthalamic nucleus they can alleviate symptoms and improve the lives of some patients with Parkinson’s disease. Traditionally, surgeons have located the target by using standard medical atlases and multiple preoperative and intraoperative imaging techniques, including 1.5-Tesla MRI. “But current methods have drawbacks,” Mandybur says. “The borders of the subthalamic nucleus can be indistinct, to the extent that sometimes we cannot visualize the nucleus well.”
To be certain that the electrodes are in the right place, surgeons have relied on electrophysiological confirmation, stimulating the target while the patient is awake and often making multiple passes through brain tissue. When surgery is prolonged in an effort to define the target, the risk of complications can increase.
In their study, Mandybur and his co-investigators will use new imaging modalities, including the more powerful 3-Tesla MRI and diffusion tensor imaging, which provides a map of critical white-matter tracts in the brain. White-matter tracts are electrical connections that should not be surgically disrupted.
The study will involve 20 patients at the James J. and Joan A. Gardner Center for Parkinson’s Disease and Movement Disorders at the UC Neuroscience Institute. Funding comes from the Sunflower Revolution, an annual fundraiser and bike ride held in Cincinnati. The Sunflower event is a collaboration among the UC Neuroscience Institute, the University Hospital Foundation and the Davis Phinney Foundation of Boulder, Colo.
Mandybur’s co-investigators are Gregory Toczyl, MD, a neurosurgeon and the 2008-2009 Davis Phinney-Donald Krumme Fellow in Parkinson’s Disease and Movement Disorders; Jim Eliassen, PhD, and Jing-Huei Lee, PhD, of the UC Department of Psychiatry; Fredy J. Revilla, MD, of the UC Department of Neurology; and James Leach, MD, of the Department of Radiology at Cincinnati Children’s Hospital Medical Center.

The Sunflower Revolution was founded in 2004 by Kathleen Krumme, a Cincinnati bicycle shop manager whose late father suffered from Parkinson’s disease, and cycling legend Davis Phinney, a former Tour de France stage-winner who was diagnosed with Parkinson’s disease at age 40. Phinney’s 18-year-old son, Taylor, is world cycling champion in the 4-kilometer individual pursuit.
Scientists at The Gardner Center for Parkinson's Disease and Movement Disorders recently received research grants totaling $153,000 from the annual Sunflower Revolution fundraiser. Professor Kim Seroogy, Ph.D., director of the Selma Schottenstein Harris Laboratory for Research in Parkinson’s, received $53,000 to study the effects of exercise therapy on stress-induced depression in an animal model. Professor Timothy Collier, Ph.D., received $50,000 to investigate the ability of antidepressants to protect dopamine neurons that are lost in the disease in an animal model. And associate professor Caryl Sortwell, Ph.D. received $50,000 to study the mechanism that may underlie some of the therapeutic benefits of deep brain stimulation in patients with Parkinson’s disease.
The Davis Phinney Foundation is dedicated to supporting research aimed at understanding, preventing, and treating Parkinson’s disease. The Foundation also seeks to find ways to improve the lives of individuals challenged by the disease.

CINCINNATI—Scientists at the James J. and Joan A. Gardner Family Center for Parkinson’s Disease and Movement Disorders at the University of Cincinnati Neuroscience Institute have received grants totaling $153,000 for research into Parkinson’s disease.
The funding was provided by the University Hospital Foundation, which co-hosts the annual Sunflower Revolution gala and bike ride with the Colorado-based Davis Phinney Foundation.
Kim Seroogy, PhD, a professor of neurology and director of the Selma Schottenstein Harris Laboratory for Research in Parkinson’s, received $53,000 to study the effects of exercise therapy on stress-induced depression in animal models of Parkinson’s disease.
Seroogy has previously shown that experimental depression exacerbates Parkinson’s symptoms in an animal model of the debilitating movement disorder. Depression is highly correlated with Parkinson’s disease, and exercise is known to produce antidepressant responses in individuals who have depression.
Seroogy’s team will attempt to determine the effect of repetitive exercise on coexisting Parkinson’s disease, stress and depression, with the hope that the research will lead to non-pharmocological therapies that will alleviate both mood and motor symptoms of Parkinson’s.
Tim Collier, PhD, a professor of neurology, received $50,000 to investigate the ability of antidepressants to protect dopamine neurons that are lost in the disease in an animal model of Parkinson’s. Although many studies have evaluated the safety and effectiveness of antidepressants in the Parkinson’s disease population, no one has directly investigated whether antidepressants impact the continuing progression of the disease.
About 40-50 percent of Parkinson’s patients are diagnosed with depression and take antidepressants daily. Therefore, it is important to determine whether antidepressants have any effects on the cells that are normally lost in Parkinson’s disease in addition to their ability to relieve the symptoms of depression.
Collier hopes that a better understanding of the impact antidepressants have on the degenerating dopamine system will help clinicians provide better treatment to patients with both depression and Parkinson’s disease.
Caryl Sortwell, PhD, associate professor of neurology, received $50,000 to study the mechanism that may underlie some of the therapeutic benefits of deep brain stimulation in patients with Parkinson’s disease. More than 20,000 patients had received deep brain stimulation—electrical stimulation of the subthalamic nucleus via implanted electrodes—as of 2006.
Sortwell and her co-investigators will use an existing rodent model of Parkinson’s to study the effects of acute and chronic deep brain stimulation on the neurotransmitter glutamate. In a previous study funded by the Davis Phinney Foundation and the University Hospital Foundation, Sortwell found that the act of stimulating neurons with electrodes boosted the amount of a nurturing, growth-promoting protein in the rats’ brains.
In her new study, Sortwell will incorporate state-of-the-art technology to detect low levels of glutamate in the substantia nigra, an area of the brain that receives inervation from the subthalamic nucleus and that contains dopamine neurons. Sortwell also will use the study to document the extent to which deep brain stimulation protects healthy dopamine neurons in the rodents’ brains.
The UC Neuroscience Institute, a regional center of excellence at UC and University Hospital, is dedicated to patient care, research, education, and the development of new treatments for stroke, brain and spinal tumors, epilepsy, traumatic brain and spinal injury, multiple sclerosis, Parkinson’s disease, Alzheimer’s disease, disorders of the nerves and muscles, disorders of the senses (swallowing, voice, hearing, pain, taste, and smell) and psychiatric conditions (bipolar disorder, schizophrenia and depression).
CINCINNATI–Deep brain stimulation, a surgical technique often viewed as a last resort for people with Parkinson’s disease, halts the progression of dopamine-cell loss in animal models, according to preliminary research by scientists at the Neuroscience Institute at the University of Cincinnati (UC) and University Hospital.
The scientists also discovered clues to why the technique works. The act of stimulating neurons with electrodes boosted the amount of an important protein in animals’ brains. The protein, a trophic factor known as BDNF (brain-derived neurotrophic factor), is a nurturing, growth-promoting chemical.
Parkinson’s disease is a degenerative neurological disorder involving the death of dopamine-producing brain cells, or neurons.
“Demonstrating that deep brain stimulation halts the progression of dopamine-cell loss was basically a confirmation and extension of previous findings,” says Caryl Sortwell, PhD, associate professor of neurology at UC and the study’s lead investigator. “But finding the mechanism is a novel discovery that is even more critical. We now know not only that it works, we also are beginning to understand how it is working.”
Sortwell recently announced her team’s results at a professional conference held by the Cleveland Clinic and the National Institute of Neurological Disorders and Stroke.
The research holds important implications for patients with Parkinson’s disease and could alter the current recommended timetable for surgical intervention.
In a typical treatment scenario, a patient has lost about 50 percent of his or her dopamine-producing neurons when symptoms first appear and a diagnosis is made. The typical patient then waits an average of 14 additional years before undergoing deep brain stimulation surgery. During that 14-year span, medications can offer symptomatic relief, but cell loss continues unabated. There is at present no cure for the disease.
Sortwell’s research was a response to an observation by physicians, including co-investigator George Mandybur, M.D., associate professor of neurosurgery, who have long been able to neutralize, in certain patients, some of the most debilitating symptoms of Parkinson’s disease, including tremor, stiffness, and slowness, by stimulating an area deep within the brain.
“The surgery for Parkinson's disease has been available for over 10 years, and in that time we have noticed that in some patients the disease does not seem to progress as rapidly after surgery as it did before the surgery,” says Mandybur, a neurosurgeon with the Mayfield Clinic. As a result, he and others theorized that DBS not only alleviated symptoms, but also provided neuroprotection.
The UC study, Mandybur says, “helps us to understand why this is going on and what may be happening in the brain. It also gives some evidence to support performing the surgery earlier to slow the overall progression of Parkinson's disease.”
Sortwell’s study, which is continuing, is supported by a $120,000 grant from the Sunflower Revolution fundraiser, a partnership of the University Hospital Foundation and the Davis Phinney Foundation. The 2008 Sunflower Revolution, scheduled for Sept. 5-7, includes a gala, a free educational symposium for patients, families and caregivers, and bike rides of 20, 40, and 100 kilometers. (See www.sunflowerrev.org.)
During the DBS study, researchers implanted high-frequency stimulating electrodes in the subthalamic nucleus, an area of the brain associated with movement, in rats and then induced dopamine neuron loss. When the rats had experienced a 50 percent loss of dopamine neurons, the researchers initiated brain stimulation in half of the group. Measurements of surviving, functioning dopamine neurons in rats implanted with active stimulators were then compared to a control group implanted with inactive stimulators. While the control group’s loss of dopamine neurons increased to 75 percent after two weeks, the rats implanted with active stimulators experienced no further loss of cells during that time.
Subsequent tissue analysis revealed that in rats implanted with active stimulators the trophic factor BDNF had tripled in the striatum, a part of the brain that houses dopamine terminals and “receives” the dopamine neurotransmitters that are produced in the substantia nigra.
The study has brought together investigators from four academic disciplines: Sortwell, and Timothy Collier, PhD., and doctoral student Anne Spieles-Engemann, from UC’s department of neurology; Michael Behbehani, PhD, from the department of physiology; Jack Lipton, PhD, from the department of psychiatry; and Mandybur, from the department of neurosurgery. Michael Behbehani, PhD, professor of molecular and cellular physiology and anesthesia, established the method for implanting the electrodes in the rat’s tiny subthalamic nucleus.
