1. Because axonal continuity is lost, Wallerian degeneration occurs. 2. Wallerian degeneration outside the lesions has been reported.3. Thalamus degeneration in MS presents several features, such as trans-neuronal or Wallerian degeneration . 4. Macrophages also play a role in inducing the proliferation of Schwann cells that occurs during Wallerian degeneration . 5. Degeneration appears distally in the paralysed facial nerve but this takes time, this process is called Wallerian degeneration . 6. Symptoms of Wallerian Degeneration ( also known as Brain Stem Degeneration ) are rare but prominent in early onset cases. 7. Another possible effect of Bell s palsy is Wallerian Degeneration ( WD ), which may take days to become evident. 8. Following Wallerian degeneration the axon regenerates along the original nerve path at a rate of approximately 1 2 mm per day. 9. Wallerian degeneration occurs after axonal injury in both the peripheral nervous system ( PNS ) and central nervous system ( CNS ).10. This results in degeneration of the intracellular elements, axons, and myelin sheath ( which houses the neuroma ) with wallerian degeneration .
