Research Explores Virtual Reality Floor Test for Early Alzheimer’s Disease.
Funded by an R21 grant from the National Institutes of Health, our research examines the validity of a virtual reality floor maze test that could help identify early signs of Alzheimer’s disease.
Getting lost in familiar spaces can be one of the earliest and most alarming indications of Alzheimer’s disease. With the help of virtual reality technology, this warning sign could soon be used as an opportunity for early diagnosis, too.
Funded by the National Institutes of Health, our study of a virtual reality floor maze test could identify an accessible, non-invasive opportunity to identify Alzheimer’s disease early in the preclinical phase, when treatment is most effective.
A progressive brain disorder caused by damage to nerve cells, Alzheimer’s disease is a type of dementia and one of the leading causes of death in the U.S. About 6.9 million people in the U.S. lived with the condition in 2020. The U.S. Centers for Disease Control and Prevention estimates that number will double to nearly 14 million by 2060.
Existing tests for Alzheimer’s disease, including PET scans and biomarker tests of cerebrospinal fluid, tend to be invasive, expensive, and difficult to access, especially for patients in rural areas.
Symptoms of Alzheimer’s disease can include problems with cognition, including memory loss, difficulty completing familiar tasks, and trouble with spatial navigation. People may get lost in their environment even before they have other signs of cognitive decline.
Our study explores the validity of a virtual reality floor maze that could help spot spatial navigation symptoms of Alzheimer’s disease when irreversible nerve damage has just begun, giving patients the best chance at effective treatment.
Improving spatial navigation testing.
Spatial navigation is a complex skill that integrates visual perception, spatial orientation, learning, and memory information. These processes occur in the brain’s medial temporal lobe, where Alzheimer’s disease first causes damage.
Existing spatial navigation tests that use mazes have limitations.
Paper and pencil and computer-based tests don’t engage the multisensory process involved in spatial navigation. Plus, they can be limited by educational and cultural factors, such as being limited to one language, which can reduce their effectiveness.
Active navigation tests, in which a patient navigates a maze on the floor, provide better results. They integrate brain signals as patients physically move through the maze, and performance on these tests has been shown to predict future risk of developing cognitive impairment. Yet because patients can see the exit (called vista navigation), these tests don’t accurately simulate the full experience of navigating through space (known as environmental navigation). Plus, they’re time-consuming to lay out and challenging to change.
We think virtual reality technology can help.
We’ve used a commercially available VR headset and free software to create virtual floor mazes that can be easily changed, and they can include virtual walls so patients can’t always see the exit. This allows us great flexibility to present new maze challenges to patients and precisely track their movements within a safe 33-foot by 33-foot room outfitted with cameras.
We’re studying this method to determine whether the VR maze tests can be effective and non-invasive and whether further testing is necessary to diagnose Alzheimer’s disease.

Studying the validity of a VR floor maze test.
In this study, we’re enrolling participants over age 65, including people with mild cognitive impairment. They will navigate four mazes representing two types of navigation (vista and environmental)) and two types of exploration (walking and keyboard):
-
Environmental navigation: VR maze with walls
-
Vista navigation: VR maze without walls
-
Walking exploration: Completing the VR maze while walking in real space
-
Keyboard exploration: Completing the VR maze while seated using a keyboard
Before each maze, participants will see the course and plan their route. After completing each maze, participants will be asked to wait 10 minutes before trying again without a chance to prepare.
We’ll monitor how long each maze takes to finish neurological tests to learn about their brain function. We’ll observe how their brain works using functional near-infrared spectroscopy while they’re at rest and navigating the maze, and we’ll analyze their gait using trackers attached to their ankles and hips.
With all this data, we’ll seek to learn:
-
If the virtual reality floor maze test exposes differences in navigation performance with or without walls and with and without walking
-
If the test can help differentiate between levels of risk of cognitive decline
-
How floor maze test results relate to participants’ performance on neurological tests
If the VR maze test proves valid, it could help patients with early Alzheimer’s better understand their cognitive future, and it could have benefits in detecting other conditions, too, including traumatic brain injury, Parkinson’s disease, and autism.
Innovating for tomorrow.
We’re enrolling participants with mild cognitive impairment at MedStar Franklin Square Medical Center in partnership with Dr. Gary Volkell. Participating in clinical trials can allow patients to get advanced care before it’s available to the public, and your involvement can help shape science and healthcare for future generations.
To learn more or enroll, contact Clinical Research Coordinator Cynthia Yashinski.
We believe the virtual reality floor maze test can help more people get essential information about potential cognitive decline. Critically, these tests may be able to show evidence of decline earlier, allowing more patients an opportunity for effective treatment that can slow the progression of Alzheimer’s disease.

MS, the Flu, and You: How Influenza Can Cause Multiple Sclerosis Symptoms to Flare.
When the influenza virus invades the body, the immune system responds with inflammation. Some of the flu’s classic symptoms, like fever, are a result of this response. For people with controlled multiple sclerosis (MS), inflammation can cause symptoms to temporarily flare in what’s known as a pseudo relapse.
Most MS medications suppress the immune system, so contagious respiratory viruses such as the flu and COVID-19 can be more severe in people who are taking these treatments. I advise my patients to take common sense steps against getting sick, such as getting vaccinated against both flu and COVID.
Based on this year’s flu season in the southern hemisphere, the U.S. Centers for Disease Control and Prevention predicts an average severity in 2024-2025. Between 2010 and 2023, at least 9 million and as many as 41 million people have contracted the flu each year.
If you are one of the approximately 1 million people in the U.S. diagnosed with multiple sclerosis, there are steps you can take to reduce exposure to the flu and limit your chances of a severe infection this season.
Multiple sclerosis & inflammation.
MS is a chronic immune disease in which inflammation impacts the brain, spinal cord, and/or optic nerve. Areas of inflammation and damage to these important parts of the nervous system are called lesions, and can lead to a wide range of neurologic symptoms, including:
-
Balance issues
-
Difficulty controlling the bladder
-
Dizziness
-
Muscle weakness or stiffness
-
Tingling, numbness, or pain
-
Vision problems
In patients with MS, new inflammation or changes to the body’s stable internal environment can cause symptoms to return or worsen without new lesions. This is called a pseudo relapse.
For example, sometimes being outdoors on a hot day can raise the body’s internal temperature enough for MS symptoms to flare up temporarily. When the core temperature returns to normal, the symptoms go away.
The same thing can happen when any type of inflammation occurs, including when the immune system is fighting off a virus like the flu.

The body’s immune response to flu.
The body’s natural immune response to viral infection like influenza is complex. The immune system releases chemicals that trigger the production of virus-fighting antibodies and other cells. This can trigger inflammation, raise the body’s temperature, and cause other changes that can influence MS symptoms.
Many of the classic symptoms of influenza, such as a runny nose, coughing, fever, and muscle aches, are a result of the body working to fight the infection. If you also have a fever, chills, and body aches, be sure to rest and get plenty of fluids. It’s worth a call to your doctor to check in. We can discuss any MS symptoms you may have and prescribe an antiviral medication if necessary.
Related reading: Cold and Flu Season: 3 Reasons Why You Might Get Sick When It’s Cold Outside.
Flu prevention: Get a vaccine every year.
Medications to treat MS often work by suppressing the immune system to short-circuit symptom-producing inflammation. This leaves patients at greater risk for more severe symptoms from a viral infection like influenza.
I advise my patients to get the latest flu vaccine (and COVID, too) each year to reduce their risk of a serious viral infection. Vaccines can cause a temporary pseudo relapse of symptoms. But these flares last only up to 12 hours instead of a week or more with a flu infection.
Other precautions are similar to those we would recommend for people who don’t have MS. Wash your hands often, and wear a mask if you’re around someone who has symptoms of a respiratory infection.
There is no evidence that getting vaccinated against the flu will cause MS symptoms to worsen in the long run. But the risk of flu is real for people with suppressed immune system. Taking steps to avoid illness will protect your health this flu season and in the long term.

3 Signs It’s Time to Consider Spine Surgery for Your Back Pain.
Most people experience back pain at some point in their life. But how do you know when the pain is serious enough to seek treatment or even consider surgery?
As a neurosurgeon, this is a conversation I frequently have with my patients. It’s also something I had to consider personally soon after finishing medical school. One morning I woke with pain in my neck that shot down through my arm to my fingers like a lightning bolt. After trying ibuprofen and other conservative treatments, it wasn’t long before I got an MRI that revealed a herniated disc. At the age of 30, I ended up having a discectomy in my neck, which thankfully relieved the pain.
Back pain won’t always require surgery. In fact, most of the time, you don’t need to have back surgery to relieve pain. However, the following three signs may indicate it may be time to get an evaluation from a spine specialist to determine whether back surgery may be an option for you.
Signs you may benefit from back surgery.
1. Back pain continues to get worse, interfering with your daily life.
Back pain affects 80 percent of people at some point in their life. However, the cause or source of back pain can vary. For example, it's common to feel neck or back soreness after sleeping awkwardly or exercising, but typically, this kind of discomfort gets better after several days. In contrast, other causes of back pain may require treatment for relief.
There are several different causes of back pain that persists, including:
- Spine arthritis, which occurs through normal wear and tear on the spine as we age
- Bulging or herniated discs, which can irritate or pinch the nerves in the spine and cause pain that radiates to your arms or legs
- Spine fractures
- Tumors along the spine
In most cases, spine surgery isn’t the first thing we think of when discussing treatment for back pain. We want to help you feel better and avoid surgery whenever possible. There are many different conservative treatment options that can help improve back pain, including:
- Physical therapy
- Anti-inflammatory medications
- Steroid injections
However, if you’re experiencing chronic back pain that gets in the way of your daily life despite trying conservative treatments, it may be time to talk to a spine surgeon about other options.
2. If you feel a painful “burning” sensation in your legs or arms.
Most people can pinpoint where their back or neck hurts. But if you have a pinched nerve near your spine or neck, the nerve can actually cause the pain to shoot through your arm or your leg, depending on the nerve. How you describe the pain to your doctor can provide very strong clues to what might be going on. Imaging tests and other diagnostic tools may be used to further assess your condition and inform treatment. If nonsurgical treatment options don’t help the pain, surgery is an effective way to relieve the pressure on the nerve and alleviate discomfort.
3. You experience numbness in your legs or have difficulty walking.
While many causes of back pain can be treated with a “wait and see” approach before considering surgery, some other conditions may require surgery sooner. For example, if your spinal cord is in danger of damage or injury, we want to treat it before it gets worse.
In addition, other spine conditions can affect your ability to walk long distances and cause a feeling of numbness or weakness. These should be promptly treated. Because numbness or weakness can also be associated with other back conditions, it’s important to get a thorough spine evaluation to assess all potential causes of your pain. This ensures you get individualized treatment that is specific to your particular condition and symptoms.
When should I see a doctor for spine pain?
You probably don’t need to rush off to the emergency room for back pain, in most cases. For example, if you know you just worked out yesterday, it’s reasonable to rest for a few days and see if it gets better. However, if you have back pain that doesn’t improve within several weeks or if things are getting worse, you may want to give your doctor a call.
Oftentimes, when you're first evaluating back pain, seeing a physical therapist can be worthwhile. They can evaluate your muscle strain and identify any red flags, such as significant weakness in the legs, which may indicate something serious.
Talk to our MedStar Health spine specialists today.
At MedStar Health, we take a team approach to helping patients improve their back pain. With both board-certified neurosurgeons and orthopedic surgeons who specialize in spine surgery, pain management physicians, and physical therapists with specialized spine training, we have extensive expertise in treating a wide range of spine conditions with both nonsurgical treatments methods and surgery.
We know surgery can feel like a major decision, and we take our time to ensure you understand the goal of surgery as well as any potential benefits or risks. Just like everyone’s diagnosis and treatment, your outcomes will be unique to you. However, knowing what we’re dealing with before surgery helps us to predict what to expect after surgery. With the help of advanced surgical technology, including computer-assisted navigation and intraoperative imaging, spine surgery is safer than ever with minimal risks for eligible patients.

Read MoreWhat Does Recovery Look Like After a Stroke?
A stroke can be life-changing, and care often doesn’t end when upon discharge from the hospital. There is no predictable timeline for recovery, and different stroke survivors will need different levels of support to help them regain independence and confidence in their daily life. Whether you’ve experienced a stroke or you’re caring for someone who has, here are a few things you can expect.
What kind of care do stroke survivors need?
Many people need some additional care after a stroke, even a mild one. Those who have suffered a more severe stroke may continue to navigate stroke recovery for months and potentially years after treatment.
As you prepare to transition from acute care in the hospital to rehabilitation and recovery, ask the following questions to ensure you understand what happened and what comes next:
- What kind of stroke did I have?
- What brain functions have been impacted by my stroke?
- What will my recovery be like?
- Do I need to take medications?
- Will I need to follow a special diet?
- What are my risk factors for having another stroke?
- Will I be admitted to an inpatient rehabilitation facility or discharged to my home?
- Do I need to make any safety modifications to my home?
- What kind of support will I need at home?
- What services are available at MedStar Health to help me adjust to life after a stroke?
Stroke rehabilitation.
Many patients benefit from stroke rehabilitation, which helps them to regain their strength and independence while recovering from the effects of a stroke. This may involve working with a physical therapist to improve mobility and balance, an occupational therapist to regain confidence in daily activities, and/or a speech therapist to regain communication skills. Your rehabilitation plan will be tailored to your unique short and long term goals, based on your specific needs.
We offer a unique, comprehensive inpatient rehabilitation program at MedStar Good Samaritan Hospital. It’s accredited as a Specialty Program by the Commission on Accreditation of Rehabilitation Facilities (CARF), highlighting our commitment to the highest quality of stroke recovery care. Our neurorehabilitation center ranks among some of the best in the region, with higher patient satisfaction rates and better “gains per day” (a functional improvement measure) than Maryland averages. Patients also benefit from a smooth transition to therapy at any one of our 50 outpatient sites in the region, when appropriate.
Emotional support.
A stroke can significantly impact survivors and their family’s life, which is why we also offer monthly support groups for patients and caregivers. During support group meetings, we discuss a variety of topics, with sessions dedicated to answering patient questions and offering support for the struggles they’re experiencing. With the encouragement and support of family, friends, and peers, our patients find the strength and motivation to overcome challenges they face after their stroke and reclaim their highest quality of life.
Preventing secondary strokes.
One in four stroke survivors will experience another stroke, which is why stroke prevention is an important part of recovery. One of the best ways to minimize your chances of another stroke or serious health event is to partner closely with your primary care provider to manage risk factors.
While a stroke can happen to anybody, certain factors increase your risk of stroke, such as:- Smoking
- High cholesterol
- High blood pressure
- Diabetes
Sometimes, having a stroke can be a wake-up call to adopt healthier habits that may lower risk factors for chronic conditions and other health complications. A primary care provider who knows your personal and family medical history can help create a plan to optimize your overall well-being. At MedStar Health, patients have access to a wide range of services and programs that can help you achieve your health goals and reduce your risk of a secondary stroke, from smoking cessation programs to dietary support services.
After a stroke, we’re invested in your recovery.
Our Comprehensive Stroke Center at MedStar Franklin Square Medical Center provides a Post Stroke Follow-Up Clinic, where stroke survivors can gain access to the right resources and support to help them move forward with a healthier life. Through the clinic, our providers and staff can help them address risk factors, receive individualized education, and learn about lifestyle modifications that will help improve their recovery and outcomes. In addition, referrals and physician follow-up are provided as needed.
And, you’ll gain access to all of the resources and expertise within the entire MedStar Health system, including primary care providers, emergency department providers, neurologists, neurosurgeons, rehabilitation specialists, and nurses who can help you achieve your highest level of health. With one electronic health record, we seamlessly communicate and coordinate with your entire care to enhance your recovery and also prevent future strokes. Patients do not need to have received emergent stroke treatment at a MedStar Health hospital in order to participate. To schedule an appointment, please call 443-777-7320.

Read MoreB.E. F.A.S.T to Recognize the Warning Signs of a Stroke.
May is National Stroke Awareness month and a good opportunity to help people understand how to recognize a stroke and why it’s important to get immediate medical care. Stroke treatment is most effective when it’s given as soon as possible after symptoms begin. In fact, every minute counts when it comes to getting stroke treatment. That’s why knowing the warning signs of a stroke is critical to helping you or a loved one get to the emergency room fast.
A stroke is essentially a “heart attack” in the brain.
Most people know that chest pain is a sign of a heart attack and a reason to quickly dial 911. Fewer men and women know that a fast response is just as important if you have any signs of a stroke.
Stroke is caused by either loss of blood flow (ischemic stroke) or blood accumulating where it doesn’t belong (hemorrhagic stroke). Regardless of the cause or type of stroke you have, the moment a stroke occurs, brain tissue begins to die rapidly. Unlike a heart attack, most strokes are painless, which is why some people may mistakenly wait it out to see if things get better.
Unfortunately, delayed care can lead to permanent brain damage or even death. For every minute that goes by, roughly two million brain cells can be lost. The earlier you can receive treatment, the more brain cells we can save and the better we can preserve your neurological function.B.E.F.A.S.T to recognize the warning signs of a stroke
We use the acronym B.E. F.A.S.T. to help people identify symptoms of a stroke. Because a stroke occurs so suddenly, often someone around you may notice warning signs before you do. Knowing the following warning signs may also help you to quickly spot a stroke occurring in someone else:
B - Balance
Changes in coordination may be a sign of a stroke. If someone has difficulty walking due to dizziness or weakness in one or both sides of the body, call 911.
E- Eyes
Visual impairments in one or both eyes, such as double vision or loss of eyesight, may be another warning sign.
F - Face
Drooping on one or both sides of the face may indicate a stroke. Look at the eyes, cheeks, or lips to see if you notice any abnormal drooping.
A - Arms
Another warning sign of a stroke is weakness in either arm. Most commonly, strokes affect one side of the body, so check if one arm might appear to be weaker than the other.
S - Speech.
Someone who is experiencing a stroke may have difficulty communicating. This could sound like slurred speech or words that don’t really make sense, signaling confusion. Ask the person to repeat a simple phrase to see if you notice any speech impairments.
T - Time
If you or someone around you experiences one or more of these stroke symptoms, call 911 immediately to get to a hospital for life-saving treatment. Be clear with the 911 dispatcher that you’re experiencing or witnessing stroke signs. Do not attempt to drive to the emergency room on your own.
Even if your symptoms subside within five minutes, it’s important to seek prompt care. A small blood clot may have caused a “mini-stroke” or transient ischemic attack (TIA). While this may not result in damage to brain tissue, it’s often a warning sign that a larger, serious stroke may be coming. Your healthcare providers can help you understand and lower your risk of having a real stroke by addressing the underlying cause(s).
Don’t wait for pain. Call 911 at the onset of any warning signs.
If you don’t have pain at the onset of a stroke, you may be inclined to wait and see if it gets better. But the faster you can get to the hospital to receive treatment within the appropriate time window, the higher the likelihood that you can leave the hospital with the best possible results. Treatments have time windows and we want to save as much brain tissue as possible. Intravenous (IV) medications that restore adequate blood flow must be given within 4.5 hours after your first symptom. And emergency endovascular procedures must be performed as soon as possible within 24 hours.
Time really matters. When you know how to B.E. F.A.S.T and call 911 at the signs of a stroke, you significantly increase the chances of getting the care you need to reverse or prevent stroke damage as quickly as possible.
