Vision Problems and Pituitary Tumors

Nearly everyone notices vision problems, especially as you get older. In the great majority of cases, this is simply due to changes in the focusing capacity of the lens, and the solution is wearing glasses. However, it isn’t safe to assume that this is always the case. It’s important to have your eyes examined by a trained professional to determine whether something more serious is affecting the eye or the vision nerve. 

In the video below you’ll learn about something I commonly see in my practice – vision loss from a tumor of the pituitary gland that is putting pressure on the vision nerves. This type of vision loss typically reduces the peripheral vision to either side. This can be diagnosed by a test at the eye doctor called Visual Fields. As in this case, a relatively simple operation can reverse the vision problem before it becomes permanent. The key is early diagnosis. If you notice that your peripheral vision is affected, ask your eye doctor to check visual fields.

 

SNI Research Aims to Expand Cerebral Palsy Therapy Options

Before they learn to crawl or walk, about 10,000 babies every year in the United States will develop a condition that will change how they will do just that. Cerebral palsy (CP) is a neurological condition caused by a brain injury before birth, during delivery or before a child’s second birthday. An estimated 800,000 Americans live with CP.

The most common symptom in CP is spasticity, an increase in muscle tension that impairs proper movement. Abnormal postures or movements, weakness or loss of muscle control and rigidity are also part of the constellation of CP signs and symptoms. While physical therapy remains the cornerstone for treatment, new medications and therapies for CP are being developed to help improve and manage symptoms.

Currently, Swedish Neuroscience Institute is participating in a study to determine the safety and tolerability of one such medication. Dalfampridine (AMPYRA ®) is a medication currently used to help improve walking speed in multiple sclerosis (MS) patients. This phase I clinical trial aims to evaluate AMPYRA’s® safety, tolerability and its effect on sensorimotor function of adults with CP. The study will look at how single and multiple doses of the medication have on CP patients, including:

  • Hand strength
  • Manual dexterity
  • Walking speed
  • Gait

There is no cure for cerebral palsy. Therapies for CP ...

Swedish Contributes to New Treatment Option for Multiple Sclerosis

 On September 12, 2012, the Food and Drug Administration (FDA) approved teriflunomide for the treatment of multiple sclerosis (MS). Teriflunomide (AUBAGIO) is a once-daily pill for the treatment of relapsing forms of MS. Led by Dr. Lily Jung Henson, the Swedish Neuroscience Institute was among several clinical sites that tested the drug. Results of the research showed that teriflunomide can lessen MS disease activity. Specifically, it behaves similarly to injectable therapies by slowing MS relapse frequency, the rate of disability and MRI activity.

The safety profile, however, is more challenging than ....

Announcing New Swedish Cerebrovascular Support Group

It is with great pleasure that I announce the beginning of the Swedish Cerebrovascular Support Group. Over the last several months, the care team here at Swedish has had many patients reach out and ask if a service like this was available. I am so glad that the answer is now yes!

Receiving a diagnosis like a cerebral aneurysm is for many a scary and stressful situation. Support groups are a fantastic way for people to alleviate fear and anxiety through discussion and education. These meetings will be a place to connect patients, family members, and caregivers together to share their experiences and advise with one another. The group is open to patients and family members of patients that have been diagnosed with or treated for a cerebral aneurysm or arteriovenous malformation (AVM).

Using Ultrasound for Treatment of Brain Hemorrhage

In September, I co-authored this cover article in the Journal of Neurosurgery on the results of a study using ultrasound for the treatment of brain hemorrhage. The study involved 33 patients with spontaneous intracerebral hemorrhage who were screened for inclusion in a SNI clinical study known as “SLEUTH” (Safety of Lysis with Ultrasound in the Treatment of Intracerebral and Intraventricular Hemorrhage). You can the abstract and full text of the article or see background information on the study, and watch a related video on WebMD.

Best seats in the house…or in this case, the OR

If you’ve ever wanted to sit in the gallery of Grey’s Anatomy and watch a surgery, we have something for you that’s a little more powerful. On Friday, we invite you to tune in to a livestream of a procedure that changes patients’ lives.

 

On Friday, Dec. 16, 2011 from 9 a.m. to 12 p.m. (PST), Drs. Ron Young and Ryder Gwinn, surgeons from the Swedish Neuroscience Institute, will host a livestream on this page to discuss the affects of Essential Tremor (ET), the Deep Brain Stimulation (DBS) surgical procedure used to treat ET and the other innovative treatment options for ET available at Swedish and throughout the country.

ET is a progressive neurological condition that causes a rhythmic trembling of the hands, head, voice, legs or trunk. It is often confused with Parkinson’s disease and is often un-diagnosed.

The livestream will feature a video stream of a recorded DBS surgical procedure performed at Swedish, accompanied by a live web chat led by Drs. Young and Gwinn. The DBS device is like a pacemaker for the brain. During the surgery, a tiny wire is implanted in the area of the brain that controls abnormal movement. This wire modifies the brain’s electrical signals to help control tremors and other abnormal movements.

It gets better

Not only will you have a front seat (from the comfort of home or wherever your mobile device is) to see a life-changing surgical procedure, but you can also ask questions live to our surgeons about the surgery, essential tremor, and any other related questions you may have (like what is Gamma Knife?). And, we’ll have patients who will share their stories about the procedure and how it has changed their lives – for the better.

Tune in on Friday

How do you know if you're having a stroke?

Hopefully, you won't have a stroke. But if you do, do you know what to do? Why is it important that you get to an emergency room quickly? Knowing the signs and symptoms of stroke could help save your life or the life of a loved one. How do you lessen your risk of having another stroke? Is your family at increased risk? Dr. William Likosky, director of Swedish Stroke and Telestroke programs, explains.
