ME/CFS (Chronic Fatigue): What It Is, Why It Happens, and Why Recovery Is So Complex

Chronic Fatigue Syndrome, also known as Myalgic Encephalomyelitis (ME/CFS), is far more than simply feeling tired.

In this video, Dr. Kaplan explains the science behind ME/CFS, including why patients experience debilitating fatigue, post-exertional malaise (PEM), brain fog, non-restorative sleep, and flu-like symptoms that can persist for years.

He explores how dysfunction in the immune system, nervous system, and cellular energy production may contribute to this complex condition—and why so many patients are often misunderstood or misdiagnosed.

You’ll learn:

✔ What ME/CFS is and how it differs from ordinary fatigue
✔ Why post-exertional malaise (PEM) is a defining symptom
✔ The role of neuroinflammation and the “brain on fire” phenomenon
✔ How mitochondrial dysfunction may contribute to profound exhaustion
✔ Why brain fog occurs and what it may reveal about the condition
✔ The connection between ME/CFS and viral triggers such as Epstein-Barr virus, Lyme disease, and Long COVID
✔ Why traditional approaches sometimes fall short
✔ Integrative and emerging approaches being explored for ME/CFS treatment

Dr. Kaplan also discusses the overlap between ME/CFS and fibromyalgia, a condition that shares some biological mechanisms but has its own unique features.
