Why Vestibular Testing Matters for POTS and Dysautonomia

If you live with POTS or another form of dysautonomia, you’ve probably had your heart rate and blood pressure checked more times than you can count. Those numbers matter. But for many people, they only tell part of the story.

At Lancaster Brain & Spine, we often meet patients who have done everything they were told: more fluids, more salt, compression garments, maybe medication. Some feel a little better. Many still feel dizzy, foggy, and wiped out when they stand. One piece of the puzzle that’s often overlooked is the vestibular system, the balance center in your inner ear and brain. Here’s why we test it, and why it can make such a difference.

Your Inner Ear Does More Than Balance

Most people think of the inner ear as the part of the body that keeps us from falling over. That’s true, but it does much more. Your vestibular system is your body’s reference point for where your head is and which way is up. Tiny sensors in the inner ear detect gravity and every tilt, turn, and change in position, and they report it to your brain all day long.

Your brain uses that information, along with signals from your eyes, joints, and muscles, to keep an up-to-date map of where every part of your body is in space. Think of it like the GPS on your phone, constantly recalculating as you move. Your brain can’t send help to the right places if it doesn’t know where those places are.

Standing Up Is a Team Effort

Think about what happens when you get out of bed in the morning. In about a second, your body has to do two big jobs at once:

  • Turn on the right muscles in your legs, trunk, and back to hold you upright
  • Adjust your blood vessels so blood doesn’t pool in your legs and keeps flowing up to your brain

Your vestibular system helps with both. Signals travel from the inner ear down pathways in the brainstem and spinal cord (the vestibulospinal pathways) that switch on the muscles that keep you upright. At the same moment, that same information about your position helps the brainstem tighten blood vessels and support your blood pressure. Researchers call this second piece the vestibulosympathetic reflex. It works alongside the pressure sensors in your neck and chest, and it’s one of the fastest ways your body gets ready for standing, often before your heart even has to react.

In other words, the same “you’re standing up now” message that tells your muscles to work also helps make sure your blood ends up where it’s needed.

What Happens When That Signal Is Off?

When the vestibular system and the brain aren’t communicating clearly, your brain’s map can be a little off, and the body may get the wrong message about what’s happening. The result may be a response that’s too strong, too weak, or poorly timed. For someone with POTS, that can look like:

  • A racing heart when standing, as your heart works overtime to make up the difference
  • Lightheadedness or feeling like you might pass out
  • Nausea or a “seasick” feeling
  • Brain fog and trouble concentrating
  • Feeling unsteady, off-balance, or visually overwhelmed in busy places

Emerging research supports this connection. Recent studies have found that people with POTS often show differences in how their otolith organs respond compared with people without POTS, and that these differences are linked to how their heart rate and blood pressure behave. The research is still growing, but it points to the vestibular system as a meaningful part of the picture for many patients.

Why Standard Workups Often Miss It

A typical POTS evaluation focuses on the cardiovascular system: heart rate, blood pressure, and sometimes bloodwork. Those tests are important, and we use them too. But the vestibular system is rarely checked. If an inner ear or brain-processing issue is helping drive your symptoms, it can go unnoticed for years. That’s one reason so many people with dysautonomia feel like they’ve tried everything without real progress.

How We Evaluate the Vestibular System

Our approach is to look at the whole person, not just a single number. Alongside tilt table testing, our evaluation includes:

  • Videonystagmography (VNG): a comfortable test where you wear special goggles so we can precisely record your eye movements. Because your eyes and inner ear are closely wired together, this gives us a clear look at how your vestibular system and brain are working.
  • Eye movement assessment: how smoothly your eyes track, how accurately they jump between targets, and how steady your vision stays when your head moves. The areas of the brain and brainstem that control eye movements sit right next to the areas that help regulate your autonomic nervous system, so your eyes offer a valuable window into how those systems are functioning.
  • Neck and cervical spine evaluation: your neck sends a constant stream of position information to the same brain centers that handle balance and autonomic control, so neck problems can add to the mix.
  • A broader look at related factors, such as breathing patterns and conditions like EDS and MCAS that commonly overlap with POTS.

Putting these pieces together gives us a complete picture of what may be driving your symptoms, so your care plan can be built around you.

What Vestibular Treatment Can Look Like

When testing shows the vestibular system is part of the problem, treatment is gentle, specific, and paced to what your body can handle. Depending on your results, it may include:

  • Targeted vestibular and eye movement exercises to help your brain process balance information more accurately
  • Gradual position and tilt work to help your body build tolerance to being upright
  • Neck and posture care when the cervical spine is contributing
  • Home exercises you can do in short sessions on good days and hard days alike

Our goal is never to push you past your limits. We start where you are, watch how your body responds, and build from there. Many patients tell us that simply understanding why they feel the way they do is a huge relief.

You Deserve a Complete Evaluation

If you’ve been living with POTS or dysautonomia and still don’t have the answers you need, the vestibular system may be worth a closer look. You’re not imagining your symptoms, and you don’t have to keep guessing.

At Lancaster Brain & Spine in Lancaster, PA, we offer tilt table testing, VNG testing, and a full vestibular evaluation in one place. If you’d like to learn more, call us at 717-299-9600 or book a consultation through our website. We’d love to help you find your next step forward.

Peripheral Neuropathy: A Functional Neurologist’s Approach to Laser Therapy

Peripheral neuropathy is a condition characterized by damage to the peripheral nerves, which transmit signals between the central nervous system (the brain and spinal cord) and the rest of the body. This damage can lead to symptoms such as numbness, tingling, burning pain, and muscle weakness. As a functional neurologist, my approach to treating peripheral neuropathy is holistic, focusing on both symptom management and addressing the underlying causes. One of the most promising treatments in our arsenal is laser therapy.

Understanding Peripheral Neuropathy

Peripheral neuropathy can result from a variety of causes, including diabetes, autoimmune diseases, infections, trauma, and exposure to toxins. The condition can affect sensory nerves (which control sensation), motor nerves (which control movement), or autonomic nerves (which control functions such as blood pressure and heart rate). The diversity of symptoms and causes makes it crucial to adopt a comprehensive and individualized treatment plan.

The Role of Laser Therapy

Laser therapy, particularly low-level laser therapy (LLLT) or cold laser therapy, has emerged as a powerful treatment for peripheral neuropathy. This non-invasive therapy uses specific wavelengths of light to penetrate the skin and stimulate cellular processes that promote healing. Here’s how laser therapy benefits patients with peripheral neuropathy:

    1.    Nerve Regeneration: LLLT stimulates the production of nerve growth factors and enhances mitochondrial activity, leading to improved energy production (ATP) in nerve cells. This promotes the repair and regeneration of damaged nerves.

    2.    Improved Blood Circulation: Laser therapy enhances microcirculation, increasing blood flow to the affected areas. This improved circulation delivers essential nutrients and oxygen to the damaged nerves, accelerating their recovery.

    3.    Pain Reduction: The anti-inflammatory effects of laser therapy help reduce pain and discomfort. By decreasing the production of pro-inflammatory cytokines and promoting the release of endorphins (natural painkillers), LLLT provides significant pain relief for many patients.

Integrative Approaches

While laser therapy is central to our treatment strategy, it is often most effective when combined with other therapies. This multimodal approach ensures comprehensive care and addresses the various aspects of peripheral neuropathy.

    1.    Nutritional Support: Proper nutrition is vital for nerve health. Key supplements that support nerve function and repair include:

    •    Alpha-Lipoic Acid: An antioxidant that reduces oxidative stress and improves nerve function.

    •    B Vitamins: Particularly B1 (thiamine), B6, and B12, which are essential for nerve health and regeneration.

    •    Omega-3 Fatty Acids: These have anti-inflammatory properties and support nerve repair.

    Be sure to check with your healthcare provider before starting any new supplements. 

    2.    Electrical Stimulation: Techniques such as Pulsed Radiofrequency Neuromodulation can complement laser therapy. Electrical stimulation helps to enhance nerve function and reduce pain by interrupting pain signals to the brain. 

    3.    Lifestyle Modifications: Addressing underlying conditions like diabetes through diet, exercise, and weight management is critical. For example, maintaining optimal blood sugar levels can prevent further nerve damage and enhance the efficacy of other treatments.

Clinical Evidence and Case Studies

Research and clinical experience strongly support the efficacy of laser therapy for peripheral neuropathy. Studies have shown that patients undergoing LLLT experience significant improvements in pain reduction, nerve conduction, and overall function. Many patients report decreased reliance on pain medications and improved quality of life.

In our practice, we have witnessed remarkable transformations across a diverse range of patients with peripheral neuropathy. Individuals with conditions such as diabetic neuropathy and trauma-related nerve damage have all experienced significant improvements. Laser therapy has provided relief from chronic pain, enhanced nerve function, and restored mobility for many, enabling patients to return to their daily activities with increased ease and comfort.

Conclusion

Peripheral neuropathy can be a challenging condition to manage, but innovative treatments like laser therapy offer new hope. In our office, we emphasize a holistic approach that combines laser therapy with nutritional support, electrical stimulation, and lifestyle modifications. This integrative strategy not only alleviates symptoms but also addresses the root causes of neuropathy, promoting long-term nerve health and overall well-being.

Laser therapy has proven to be a highly effective treatment for peripheral neuropathy, offering pain relief, enhanced nerve regeneration, and improved quality of life for many patients. By embracing a comprehensive and individualized treatment plan, we can provide the best possible outcomes and help patients regain function and enjoy a better quality of life.
