How does one know they have FFI?

Fatal Familial Insomnia (FFI) is a rare genetic disorder characterized by progressively worsening insomnia, leading to severe sleep disturbances, cognitive decline, and other neurological symptoms. Diagnosis typically involves a combination of clinical evaluation, family history, and genetic testing for mutations in the PRNP gene. Symptoms often include difficulty falling asleep, memory problems, and changes in behavior. If you suspect you have FFI, it is crucial to consult a healthcare professional for proper assessment and guidance.
