Symptoms of demyelination. Axonal neuropathy is a condition in which the nerve cells begin to function abnormally because the axons are degenerating. As the brain repeatedly hits against the inside of the skull from the force of the injury, the long connecting fibers in the brain, known as axons, can tear and potentially cause severe damage. Symptoms can occur in various combinations and depend partly on the extent of the damage. See all 4.
