fatal familial insomnia (ffi) is a very rare sleep disorder that runs in families. while the main symptom is insomnia, ffi can also cause a range of other symptoms, such as speech problems and dementia. ffi gets its name partly from the fact that it often causes death within a year of two of symptoms starting. these are rare conditions that cause a loss of nerve cells in the brain. they tend to show up between the ages of 32 and 62. however, it’s possible for them to start at a younger or older age. ffi is caused by a mutation of the prnp gene. it’s this loss of cells that lead to ffi’s range of symptoms. a parent with the mutation has a 50 percent chance of passing on the mutation to their child. this can also help rule out any other causes of your sleep problems, such as sleep apnea or narcolepsy.
however, in the united states, you must have a family history of ffi or be able to show that previous tests strongly suggest ffi in order to do this. if you have a confirmed case of ffi in your family, you’re also eligible for prenatal genetic testing. a 2016 animal study suggests that immunotherapy may help, but additional research, including human studies, are needed. researches think it may be an effective way to prevent ffi in people who carry the genetic mutation that causes it. it can be years before the symptoms of ffi start to appear. however, once they start, they tend to get rapidly worse over the course of a year or two. fatigue and tiredness could be warning signs of a sleep disorder. learn how to know if you have a sleep disorder like insomnia or sleep apnea. it can cause various developmental delays, including lower mobility, speech difficulties, and… dysarthria is a speech disorder caused by brain damage.

fatal insomnia can be difficult to identify based on the symptoms alone, especially for people who have no record of a family member with the disease. diagnosing sporadic fatal insomnia involves considering similar symptoms and conducting many of the same tests used to diagnose fatal familial insomnia. sometimes, a detailed analysis of cerebrospinal fluid reveals abnormalities in people with fatal familial insomnia and sporadic fatal insomnia. treatments for fatal familial insomnia and sporadic fatal insomnia are similar and overlapping. dr. vyas is a pediatrician and founder of sleepless in nola. dr. vyas is a pediatrician and founder of sleepless in nola.
