Otherwise one would realize they had FFI only after potentially passing it on to their children. With onset landing around middle age it is essential that any potential patient be tested. The mutated protein, called PrP Sc, has been found in just 40 families worldwide, affecting about 100 people if only one parent has the gene, the offspring have a 50% risk of inheriting it and developing the disease. The average survival span for patients diagnosed with FFI after the onset of symptoms is 18 months. FFI has no known cure and involves progressively worsening insomnia, which leads to hallucinations, delirium, and confusional states like that of dementia.
