For example, one way to acquire a prion disease is through iatrogenic exposure, which is when your condition stems from medical care. Both the sporadic form and familial insomnia are rare human prion diseases.Īdditionally, prion diseases can result from an individual’s environment. Specifically, scientists say that sometimes a person can develop a spontaneous genetic mutation affecting the prion protein, known as Sporadic Fatal Insomnia. Not all cases of fatal insomnia are inherited, though. Want to know more? Find out how genes influence your risk of insomnia. Conversely, recessive genetic disorders need two mutated copies to pass along a disease. In our DNA, we inherit two copies of each gene.Īutosomal refers to when the particular gene is found on a numbered, non-sex chromosome, and dominant means that only a single copy of a mutated gene is needed to carry the disease. People inherit FFI in a gene pattern known as autosomal dominant. The accumulation of these toxic prions can cause a decrease in nerve cells, which is what causes insomnia and associated symptoms. When the gene sends abnormal signals, it can lead to malformed-and toxic-prions. Prion protein (PrP), an active protein in the brain. People with Fatal Familial Insomnia can also experience impairments with their autonomic nervous system, which is responsible for automatic bodily functions such as your heartbeat, breathing, or sweating. According to experts, insomnia symptoms continue to worsen over time. ![]() Fatal Familial Insomnia (FFI) is a degenerative brain disorder that inhibits a person’s ability to fall asleep. ![]()
