Some of our common services:
This rare noncancerous tumor presses on the hearing and balance nerves in the inner ear. A large tumor can press on facial nerves and other nerves. Our expert surgical team works with other specialists to ensure treatment contains the tumor’s growth, minimizes side effects and preserves hearing and facial functions.
MS slows down or blocks messages from your brain to your body, causing bodily symptoms. The specialists at our Multiple Sclerosis Center, one of the few comprehensive care centers for MS in the nation, are committed to improving the lives of patients who struggle with MS. UW Medicine is a National MS Society partner that has been a recognized leader in research for over 40 years, awarded with a “Partners in MS Care” designation for the highest level of comprehensive MS care. Our team of providers has extensive training and experience in MS and other related conditions to address each patient’s individual needs.
In a fast-growing field, our doctors, researchers and engineers are developing new technologies that solve neurological problems. They are taking these discoveries from the lab into clinical settings and homes to be used by patients and the public.
An aneurysm is a bulge or ballooning in the wall of an artery. If an aneurysm grows large, it can burst and cause dangerous bleeding or even death. Our surgeons offer the most advanced surgical treatments for cerebral aneurysms, with expertise in microsurgical and endovascular techniques.
Imaging and diagnostic testing help our neurosciences team accurately identify neurologic disorders, determine their severity and monitor a patient’s health after a diagnosis has been made. The specialists at our Neuro-Imaging and Diagnostic Services are skilled at using advanced imaging and diagnostic testing to help guide our patients’ care.
Parkinson's disease, tremors and other movement disorders cause a person’s body to move involuntarily. The specialists at our Movement Disorder Program are leading experts in this field. They’re skilled at diagnosing movement disorders and providing appropriate treatments that either cure the disorder or improve its symptoms and relieve its pain.
Movement disorders are caused by abnormal communication between nerve cells in the brain. DBS delivers an electrical current that will silence this abnormal communication and restore the patient’s movements closer to normal.
AVMs are abnormal, snarled tangles of arteries and veins connected to each other. These tangles occur more often in the brain or spinal cord where they interfere with blood circulation. Our skilled neurosurgeons treat AVMs effectively and safely with the latest endovascular techniques.
This medical field focuses on diseases or injuries of the nervous system that affect vision. Working together with the experts at the UW Medicine Eye Institute, our neuro-ophthalmologists are skilled at helping patients who are losing their sight or have trouble controlling their eye movement due to a nerve condition.

Proton beam therapy is FDA-approved technology that delivers external beam radiation with positively charged atomic particles to tumors. Because of its unique radiation dose deposition properties, proton beam therapy delivers radiation to tumors while reducing radiation exposure to surrounding normal tissues. The SCCA Proton Therapy Center at Northwest Hospital is equipped with the most advanced proton therapy technology available, and the physicians are UW Medicine faculty and have trained and worked at some of the best proton therapy centers nationwide.
These brain disorders cause people to experience persistent disabling or life-altering seizures. The specialists at our Level IV Regional Epilepsy Centers at Harborview and Valley Medical Center use the latest technology to correctly diagnose seizures and determine their causes. Although there is no cure for epilepsy, our specialists develop treatment plans that effectively control seizures and bring relief.
Our surgeons use the state-of-the-art robotic ROSA devise. ROSA helps our neurologists and surgeons precisely pinpoint the areas in the patient’s brain responsible for epileptic seizures. ROSA also makes surgery safer and more reliable by allowing surgeons to accurately position and handle surgical instruments.
These diseases cause muscles or nerves that control movement and sensation to deteriorate. This deterioration leads to twitching, cramps, pain and problems with joints and movement. The specialists in our Division of Neuromuscular Diseases are skilled at providing relief to patients through treatments that include drug therapy and neuro-rehabilitation.
Tumors at the base of the skull require specialized surgery. Patients who have benign or cancerous skull base tumors receive excellent care through our Skull Base Tumor Program. The program’s surgeons offer both minimally invasive endoscopic procedures and open surgery, depending on the type of tumor and its location.
This procedure uses high-energy gamma rays to pinpoint and destroy or contain a tumor without damaging surrounding brain tissue. Gamma Knife is particularly effective in targeting small, localized tumors deep inside the brain. Our Gamma Knife Center offers the latest in high-energy gamma ray technology, and recent upgrades have made us the only m￼edical system in the region to offer both mask-based and frame-based treatment options.
Also known as nerve damage, neuropathy can result from a number of conditions. Types include peripheral, cranial, autonomic, focal and, most commonly, diabetic. If you have diabetes, high blood sugar levels over a long period of time can damage your nerves. This damage can cause pain and numbness and can affect your body’s organs. Our specialists offer treatments that ease neuropathy’s pain, relieve its discomfort and contain its tissue damage.
Sleep is an essential part of your day. If you’re experiencing lack of sleep, you may find it difficult to think, concentrate and get through your day. The experienced sleep specialists at our Sleep Center will help you overcome your sleep problems with proven treatments and healthy sleep habits.

If you suffer from chronic daily headaches, the specialists at our Headache Clinic – including the only board-certified headache specialist in Washington -- can relieve your pain. They will help you manage your headaches with a multimodal approach and a personalized treatment plan that focuses on the importance of good sleep, nutrition, exercise and stress reduction. Therapies may include BOTOX, SPG, CEFALY and gammaCore.
People usually are asked to undergo neuropsychological testing to check if they’ve experienced any behavioral and cognitive changes from a neurological injury or disease. The specialists at our Neuropsychological Assessment Services are skilled at conducting these tests, interpreting the results and offering recommendations to help plan the patient’s treatment.
A stroke is a medical emergency that requires expert care. The UW Medicine Comprehensive Stroke Center at Harborview is the only one in Washington state certified by the Joint Commission for consistently providing the highest standards of care 24/7/365. Primary stroke centers are also located at Northwest Hospital and Valley Medical Center to treat all types of strokes.

The specialists in our Hydrocephalus Program bring needed relief to adults with hydrocephalus, a buildup of excess spinal fluid in the brain. We also offer a Transitional Hydrocephalus Program, in partnership with Seattle Children’s Hospital, to seamlessly transition teens into adult care.
The neurotrauma specialists at Harborview's Level 1 Trauma and Burn Center offer emergency care, surgery and therapy to people who have conditions such as traumatic brain injury, spinal cord injury, skull and spinal column fractures and concussions. Our center is the only one of its kind that provides neurotrauma care to Washington and neighboring states.
Teens with neurologic conditions have needs that are best understood by pediatric neurologists. To meet these needs, we work with Seattle Children’s Hospital to offer Transitional Neurological Care. Program neurologists are skilled in both pediatric and adult neurosciences to help teens ease into adult care as they become young adults.
Intracranial hypertension is neither a brain tumor nor a result of high blood pressure. Researchers believe that cerebrospinal fluid (CSF), the normal fluid created within the brain, does not reabsorb or drain properly into the major veins of the brain, which raises the pressure of the CSF inside the skull. Elevated cerebrospinal fluid pressure can cause headaches, and also exert pressure on the optic nerve and its blood supply, leading to swelling of the optic nerve (papilledema) and visual symptoms, including blindness.
The specialists in our Intracranial Hypertension Program understand the physical and emotional toll caused by this disease and offer the highest level of services to alleviate its pain and anxiety.

Multiple sclerosis (MS) is a long-lasting (chronic) disease of the central nervous system. Some people with MS may have only mild symptoms. Others may lose their ability to see clearly, write, speak, or walk when communication between the brain and other parts of the body becomes disrupted.
The first symptoms of MS are blurred or double vision, red-green color distortion, pain and loss of vision, trouble walking and an abnormal feeling or pain, such as numbness, prickling, or pins and needles. About 50 percent of people with MS have cognitive problems affecting concentration, attention, memory and judgment.
Causes and risk factors
The cause of MS is unknown, and there is no single risk factor for it, but several factors are believed to contribute to overall risk. Smoking, obesity, autoimmune disorders, thyroid disease, type 1 diabetes, inflammatory bowel disease and infectious agents such as viruses are all risk factors for multiple sclerosis.
An MS evaluation involves a complete health history and neurological exam. This includes: mental, emotional and language functions; movement and coordination; vision; balance; and functions of the five senses. Tests that may be used include an MRI, evoked potentials, cerebral spinal fluid analysis and blood tests.
There is no cure yet for MS. But you can do things to help change the course of the disease, treat flare-ups, manage symptoms, and improve your function and mobility. Treatments for the conditions seen with MS may include medicines, equipment such as canes, braces, or walkers and rehabilitation activities.
The complications of MS range from mild to severe. They can range from fatigue to the inability to walk. Other problems include loss of vision, balance, and bowel or bladder control. Depression can result from the difficulty of living with a chronic condition.
