Vitamin B12
Role in the nervous system:
As already mentioned, vitamin B12 is essential for myelin formation. Myelin is a fatty substance that surrounds nerve fibers in the form of a protective sheath. This sheath enables efficient and rapid transmission of electrical signals between nerve cells. Without sufficient myelin, these signals may be delayed or not transmitted at all, leading to neurological symptoms.
Deepening into polyneuropathy:
Polyneuropathy refers to a group of disorders characterized by damage to the peripheral nerves that transmit information between the brain, spinal cord and the rest of the body. Symptoms can include tingling, numbness, muscle weakness, and pain in the affected areas.
A deficiency of vitamin B12 can disrupt myelin synthesis and thus lead to degeneration of the protective myelin sheath. This can impair nerve function and lead to the characteristic symptoms of polyneuropathy.
Additionally, research has shown that vitamin B12 deficiency can not only affect peripheral nerves, but can also lead to damage in the central nervous system. This can lead to symptoms such as memory loss, disorientation and difficulty walking.
Therapeutic significance:
Timely detection and treatment of vitamin B12 deficiency can slow or even reverse the progression of polyneuropathy.
