Diagnosis
Unfortunately a specific diagnosis can only be confirmed at post-mortem.
Suspicious cases based upon clinical signs should always be submitted for
examination.
Typical pathological changes include :
- Bilaterally symmetrical vacuolation of the neuropil
- Vacuolation in neurones
These lesions are most often found in the following areas of the brain
:
- Basal ganglia
- Cerebral cortex
- Thalamus
