In brief: Slow virus
It's viral. It is a type of infection in which infection may not be evident for decades.
Slow viruses are notoriously difficult to culture but advanced dna techniques and electron microscopy can prove their presence.

Prions are similar to viruses but have a less complex structure

Pathology
In brief: Prion
This is an abnormal protein, neither a virus nor a bacterium. It is an altered version of a normal brain protein that catalyzes the transformation of this protein into copies of itself.
