In MS, the myelin sheath becomes inflamed or damaged.
Her own immune system attacked the myelin sheaths around the nerves.
The cochleae and myelin sheaths of the neural portion and auditory system are now fully developed.
These cells specialize in making sure the myelin sheath is healthy.
Therefore, with the funicular myelosis, the myelin sheath degenerates with the further development of motor and sensory impairments.
This is a reduction by more than a factor of 6 in the amount of fatty acid available to repair the myelin sheath!
In those with MS, the myelin sheath becomes inflamed or damaged.
Vitamin B12 is involved in the reactions of myelin metabolism,which further forms the myelin sheath of nerve fibers.
Throughout a person's life, the myelin sheath has to be constantly maintained and repaired.
A whopping 25% of the total cholesterol in the body isfound in the brain, and it is present in abundance both in the synapses and in the myelin sheath.
This causes the immune system to destroy the myelin sheath surrounding your axons(the extensions of a nerve cell carrying nerve signals);
As we saw earlier,fatty acid supply is essential as building blocks for the sulfatide that is synthesized by oligodendrocytes to keep the myelin sheath healthy[29].
In multiple sclerosis, the myelin sheath is damaged- it's the cover around the nerves and it's necessary for normal functioning.
So inadequate cholesterol in the synapse will weaken the signal at the outset, andinadequate fat coating the myelin sheath will further weaken it and slow it down during transport.
Another treatment option is the injection of high doses of immunoglobulins(antibodies) against antibodies that are attacking the nerves,reducing inflammation and destruction of the myelin sheath.
Genetically-engineered mice with defective oligodendrocytes exhibit visible pathologies in the myelin sheath which manifest as muscle twitches and tremors(Saher et al, 2005).
By losing the myelin sheath, the nerves become inflamed and this prevents the nervous signal from being transmitted to the muscles, leading to muscle weakness and the sensation of tingling in the legs and arms, for example.
A high concentration will lead to an increase in the rate of delivery to the brain,where it is critically needed to keep the myelin sheath healthy and to promote neuron signaling in the synapses.
This acute orchronic damage to nerves of the peripheral nervous system(primarily the myelin sheath of nerve fibers) is the result of inflammatory or autoimmune process which causes numbness of an arm or a loss of sense of touch in the body under the control of the affected nerve.
In parallel, it is becoming very clear that cholesterol is pervasive in the brain,and that it plays a critical role both in nerve transport in the synapse and in maintaining the health of the myelin sheath coating nerve fibers.
Neurons critically need cholesterol,both in the synapse[50] and in the myelin sheath[45], in order to successfully transmit their signals, and also as a first line of defense against invasive microbes.
As will be discussed further later, people with Alzheimer's also have reduced levels of B-HDL, as well as sharply reduced levels of fatty acids, in the cerbrospinal fluid, i. e,impoverished supply of cholesterol and fats to the myelin sheath[38].
The axons will figure prominently in the discussions below,because they are coated with a fatty substance called the myelin sheath, and this insulating layer is known to be defective in Alzheimer's.
Due to changes in the immune system,the body attacks the peripheral nervous system itself, destroying the myelin sheath, which is the membrane that covers the nerves and accelerates the conduction of the nervous impulse, causing the symptoms.
This is something that researchers are only beginning to appreciate, buttwo related properties of Alzheimer's are poor quality myelin sheath alongside a drastically reduced concentration of fatty acids and cholesterol in the cerebrospinal fluid….
