It is genetically inherited and mainly affects the thalamus, which is the part of the brain that controls the sleep cycle. These mice expressed a humanized version of the PrP protein that also contains the D178N FFI mutation. Progressive insomnia leading to dementia and death. Do you know of an organization?
