Motor axon excitability during Wallerian degeneration.
Axonal loss and degeneration are major factors in determining long-term outcome in patients with peripheral nerve disorders or injury. Following loss of axonal continuity, the isolated nerve stump distal to the lesion undergoes Wallerian degeneration in several phases. In the initial 'latent' phase, action potential propagation and structural integrity of the distal segment are maintained. The ...
متن کاملWallerian degeneration of the pontocerebellar fibers.
Two cases of pontine infarct with Wallerian degeneration (WD) of the pontocerebellar fibers are described. WD of pontocerebellar fibers, seen bilaterally along the transverse pontine fibers, is more visible in the middle cerebellar peduncles and extends into the white matter of the cerebellar hemispheres. Understanding the anatomy of the white matter and the temporal evolution of this degenerat...

During the entire periodof follow-up at our center, she required 20 to 30mg daily of oral prednisone. Neurological examination prior to the onset of HiCy therapy revealed symmetrically reduced arm abduction (4−/5) and hip flexion strength ...
متن کاملProgressive multifocal leukoencephalopathy with wallerian degeneration.
A 39-year-old male presented with slurred speech, left hand weakness, gait unsteadiness and headaches over a period of 4 weeks. A brain MRI revealed a right motor strip lesion with Wallerian degeneration along the pyramidal tract plus brain stem and cerebellar FLAIR changes without enhancement ( fig. 1 ). Laboratory findings included a CD4 count of 56, HIV viral load of 2,597 and a positive CSF...
متن کاملBilateral Wallerian Degeneration of the Pontocerebellar Tracts
Wallerian degeneration is the process of progressive demyelination and disintegration of the distal axonal segment following the transection of the axon or damage to the neuron. We report a case of a patient with Wallerian degeneration of the pontocerebellar tracts. She had a history of a pontine infarction 3 months ago. Wallerian degeneration of pontocerebellar tracts is seen bilaterally and s...
