Fatal sleep deprivation is caused by the systemic failure of specific autonomic and metabolic mechanisms.
Evidence from clinical and neuroimaging studies on fatal familial insomnia demonstrates that progressive sleep deprivation and eventual fatality are driven by profound autonomic and metabolic failures originating from thalamic and central neurodegeneration.
The retrieved case reports and imaging studies on fatal familial insomnia (FFI) consistently show that the fatal progression is characterized by severe autonomic dysfunction, agrypnia excitata, and structuro-metabolic abnormalities in the thalamus and connected brain regions. Since the literature uniformly points to these systemic autonomic and metabolic disruptions as central to the pathophysiology and fatal outcome of fatal sleep disorders, the claim is supported.

Specific structuro-metabolic pattern of thalamic subnuclei in fatal familial insomnia: A PET/MRI imaging study. 2022. https://doi.org/10.1016/j.nicl.2022.103026
Demonstrates that thalamic structural and metabolic dysfunction is a core pathophysiological feature of fatal familial insomnia.
