Beyond Myelin: New Scientific Discovery Reveals Why Brain Cells Die in Multiple Sclerosis
the staff of the Ridgewood blog
Ridgewood NJ, For decades, the fight against Multiple Sclerosis (MS) has been a race to protect one thing: myelin. But a groundbreaking study published yesterday has shifted the entire paradigm of how we understand this neurodegenerative disease.
Neuroscientists have identified a hidden mechanism that causes permanent brain damage, offering a “missing link” that could lead to revolutionary new treatments for the millions living with MS.
The Traditional View: The Myelin War
In a healthy body, nerve cells are wrapped in a protective coating called myelin, much like insulation on an electric wire. Multiple Sclerosis occurs when the immune system mistakenly attacks this coating, “short-circuiting” the central nervous system.
While current treatments excel at reducing these attacks, they often fail to stop the slow, progressive decline in cognitive function. This study finally explains why.
The Discovery: Gray Matter and DNA Damage
The new research reveals that while the immune system is busy attacking myelin, a second, more silent process is happening in the brain’s cortex (the outermost layer of gray matter responsible for high-level thinking).
Researchers found that chronic inflammation triggers specific chemical reactions that do more than just irritate cells—they physically shatter the DNA of gray matter neurons.
Key Findings of the Study:
-
The Target: Neurons in the gray matter, not just the white matter (myelin).
-
The Cause: Inflammation-induced chemical reactions that cause severe DNA damage.
-
The Result: Programmed cell death that leads to permanent neurodegeneration and cognitive loss.
Why This Changes Everything for MS Treatment
This breakthrough suggests that focusing solely on myelin protection is like fixing a wire’s insulation while the copper core is melting. To truly stop the progression of MS, science must now find ways to:
-
Neutralize the chemical reactions in the cortex.
-
Repair DNA damage within neurons before the cells die.
By opening this “additional path,” neuroscientists are hopeful that future therapies can preserve cognitive function and offer a higher quality of life for those with progressive forms of the disease.

Expert Insight: “The results suggest focusing solely on myelin is insufficient to treat the progressive symptoms of the disease.” — Lead Researchers
How do you think this new focus on DNA repa
In your very nice cartoon image of a neuron, Schwann cells are identified as the substance around the axon. Schwann cells provide insulation and nutrition to neurons in the peripheral nervous system and form the myelin sheath wrapped around axons. However, in the central nervous system, oligodendrocytes are the myelin making cells.
