How common is sporadic fatal insomnia?

If two copies are inherited, the offspring has a 100 percent chance of developing the disorder. When it does develop, FFI is always fatal, and the time from diagnosis to death is typically a few months to a year and not more than 18 months.
What are the symptoms of sFI?
Like FFI, sFI is characterized pathologically by thalamic atrophy and clinically by disrupted sleep, autonomic dysfunction, and motor abnormalities including myoclonus, ataxia, dysarthria, dysphagia, and pyramidal signs [3].

Can sleeping pills help FFI?
Currently there is no treatment for FFI.
