EEG and Multiple Sclerosis: A Personal Perspective on Diagnosis and Understanding

In November 2025, I experienced a health scare when I was initially told I might have multiple sclerosis (MS). It was a moment filled with uncertainty and fear.


After further evaluation, I was ultimately diagnosed with Transverse Myelitis, a condition that shares some overlapping features with MS.


I woke up one morning with numbness in my saddle region, feet, and legs. Imaging revealed a lesion on my lumbar spine. Since then, I have regained some sensation, particularly in the saddle area, but I still have persistent numbness in my feet and right leg. My neurologist explained that I may not regain full sensation.


In January, I completed a three-day steroid infusion, which has helped to some degree. The human body is incredible—but it is also humbling. The idea that the immune system can attack the spinal cord and disrupt normal function is difficult to fully grasp until you experience it.


This journey has also given me a deeper appreciation for what many of our patients go through. The uncertainty. The lack of control. The fear of the unknown. It has strengthened my empathy and changed the way I approach patient care as an EEG technologist.


It also led me to ask an important question:


What role does EEG play in diagnosing multiple sclerosis?


What Is Multiple Sclerosis?

Multiple Sclerosis (MS) is a chronic autoimmune disorder that affects the central nervous system, particularly the white matter of the brain and spinal cord. It occurs when the immune system mistakenly attacks myelin, the protective covering of nerve fibers.


Common symptoms of MS include:

  • Numbness or tingling

  • Muscle weakness

  • Changes in vision

  • Balance and coordination issues

  • Fatigue

  • Cognitive changes


Several risk factors and triggers have been associated with MS, including:

  • Smoking

  • Vitamin D deficiency

  • Infection with Epstein-Barr virus


Because MS can present in many different ways, diagnosis often requires a combination of clinical evaluation, MRI imaging, and additional testing.


Can EEG Help Diagnose Multiple Sclerosis?

While electroencephalography (EEG) is not a primary diagnostic tool for MS like MRI, emerging research suggests it may play a supportive role in certain cases.

According to studies published by the National Institutes of Health, EEG may help detect and monitor cortical (gray matter) involvement in MS—an area that is not always fully captured by traditional imaging alone.


EEG Findings in MS May Include:

  • Background slowing of alpha activity

  • Changes in brain wave organization

  • Occasional epileptiform discharges

  • Indicators of cognitive dysfunction


EEG may be particularly useful in:

  • Evaluating cognitive impairment in MS patients

  • Monitoring disease progression

  • Identifying cortical involvement not clearly seen on MRI

  • Complementing other neurodiagnostic tools


Rather than replacing imaging, EEG can serve as an adjunct tool, offering additional insight into how MS affects brain function.


A Broader Perspective on Diagnosis


What stood out most to me while reviewing the literature is that MS is not always straightforward. It is a condition that requires looking at the full picture—symptoms, imaging, clinical history, and sometimes additional testing like EEG.

As technologists, we often focus on capturing high-quality data. But behind every study is a person trying to understand what is happening inside their body.

Going through this experience myself has reinforced something important:

Our role is not just technical—it is deeply human.


Final Thoughts

EEG may not be the first test used to diagnose multiple sclerosis, but it has growing value in understanding how the disease affects brain function—especially in relation to cognition and cortical involvement.


For me, this journey has been both challenging and eye-opening. It has deepened my understanding of neurological conditions and strengthened my empathy for the patients we serve every day.

Because when you’ve experienced even a small part of that uncertainty yourself, you begin to see your work—and your patients—differently.
