Does fatal insomnia show on MRI?
In conclusion, considering fatal familial insomnia as a model of thalamic-restricted gliosis in humans, this case demonstrates that multisequences of MRI can detect prion-induced gliosis in vivo, as confirmed by our neuropathologic examination performed just a few days after radiological examination.
What is the root cause of fatal familial insomnia?
What causes it? FFI is caused by a mutation of the PRNP gene. This mutation causes an attack on the thalamus, which controls your sleep cycles and allows different parts of your brain to communicate with each other. It’s considered a progressive neurodegenerative disease.
