prion disease that affects the brain and other parts of the nervous system. Prion diseases, also known as transmissible spongiform encephalopathies (TSE), are a group of rare neurodegenerative conditions that occur when abnormal proteins clump together and accumulate in the brain, leading to tissue damage. The first symptoms of FFI usually begin in mid-life and may include insomnia that worsens over time and vivid dreams when sleep is achieved. These symptoms may be followed by high blood pressure; episodes of hyperventilation; excessive tearing; and/or sexual and urinary tract dysfunction.

Treatment aims at alleviating symptoms when possible.Fatal familial insomnia (FFI) is an inherited
