What Does MRI Showing Possible Demyelinating Disease Or Chronic Ischemia Mean?
My MRI came back with small focus ventricular signal indicating possible demylinating disease or chronic eskemia. All bloodwork is normal. Please translate, what does this mean? My Dr. says he doesn t know and it will be several months before a neurologist can see me. Thank you.

Hello,
You had an MRI. Your MRI shows possibility of demyelinating disease. Damage to the myelin around the nerves is demyelination. Myelin is an insulating material of the nerves. When it’s worn away or damaged, nerves deteriorate, causing problems in the brain and the body. Myelin allows a nerve signal to travel faster. In unmyelinated neurons, a signal can travel along the nerves slow (small focus ventricular signal).
In a myelinated neuron, the signal can travel 100 meters per second. Demyelination slows down messages sent along axons and causes the axon to deteriorate. Depending upon the location of the damage, axon loss can cause problems in co-ordination and various activity. Certain medical conditions can damage myelin, get clinically examined so that the pathology causing the symptoms can be treated at the earliest.
Chronic ischemia is the clinical condition that causes a deficient blood supply to a certain territory, of progressive establishment. Chronic ischemia of the extremities occurs as a consequence of the slow and progressive decrease of blood flow and oxygen supply. Get treated before the symptoms get worse.
Take care. Hope I have answered your question. Let me know if I can assist you further.
