	Fatal insomnia is a rare disorder characterized by difficulty sleeping, which gradually worsens over time. Other symptoms may include speech and coordination problems, as well as dementia. This prion disease of the brain eventually leads to death within months to years.		Fatal insomnia is a rare disorder characterized by difficulty sleeping, which gradually worsens over time.

Fatal insomnia is a rare disorder characterized by difficulty sleeping, which gradually worsens over time. Other symptoms may include speech and coordination problems, as well as dementia. This prion disease of the brain eventually leads to death within months to years.

=== Signs and Symptoms ===

Fatal insomnia progresses through four stages:

Increasing insomnia, leading to panic attacks, paranoia, and phobias (about 4 months)
Hallucinations and panic attacks become noticeable (about 5 months)
Complete inability to sleep, accompanied by rapid weight loss (about 3 months)
Dementia, unresponsiveness, or muteness, followed by death (about 6 months)
Additional symptoms may include profuse sweating, pinpoint pupils, sudden menopause for women or impotence for men, neck stiffness, elevated blood pressure and heart rate, and constipation.

=== Cause ===

Fatal insomnia is caused by a mutation in the protein PrPC. It has two forms: [[Fatal Familial Insomnia]] (FFI), which is autosomal dominant, and [[Sporadic Fatal Insomnia]] (sFI), which is due to a non-inherited mutation.
