New research reveals that Alzheimer's disease may impair nerve function not by reducing myelin, but by altering the proteins ...

"Myelin requires a lot of lipids [a group of molecules that includes fats] for normal function," Grutzendler says. "In Alzheimer's disease, lipid metabolism could be abnormally affected in a way ...

The disruption of axons—the thread-like part of nerve cells that transmits electrical signals—is associated with Alzheimer’s disease. One way axonal function may be hindered is through damage to the ...

Mitochondrial abnormalities, or problems in cells' powerhouses, contribute to nerve cell death linked to motor control in MS, ...

A new study reveals how mitochondrial failure in brain cells may be behind motor dysfunction in multiple sclerosis, offering ...

An experimental medicine, 2-D08, boosts motor function in mice and primate models of multiple sclerosis (MS) by repairing the myelin sheath, the protective coating on nerve fibers that’s damaged ...

Schwann cells are a type of satellite cell that function similarly to oligodendrocytes in the CNS. They create a myelin sheath around nerves, which helps insulate them for faster conduction.

For most people with MS, a cup or two a day is fine and may even help some symptoms like fatigue and cognitive function. But ...
