Fatal familial insomnia and sporadic fatal insomnia differ from other prion diseases because they affect predominantly one area of the brain, the thalamus, which influences sleep. The familial and sporadic forms typically begin between the ages of 30 and 50 years.
Terminal Insomnia - When Sleep Deprivation Is Fatal. Terminal insomnia is a very rare but deadly condition. The two main kinds of terminal insomnia, fortunately, affect fewer than 100 people in the entire world. Fatal familial insomnia is a hereditary condition in which just one amino acid in one gene for one protein is wrong. It makes a protein in which 252 amino acids are right but 1 is wrong, called a prion. As the amount of the protein builds up over decades, it eventually has devastating effects on the brain.
