A rare genetic disorder known as Fatal Familial Insomnia (FFI) condemns its victims to months of total sleeplessness, leading to exhaustion and death. The disease, caused by a misfolded prion protein, has plagued a handful of families for centuries, leaving a trail of tragedy in its wake.
Silvano, a 53-year-old Italian man, first noticed symptoms while on a cruise: excessive sweating and constricted pupils. He recognised the signs from his father and sisters, who had died from the same mysterious illness. Despite knowing his fate, he donated his brain to science to help unravel the disorder.
Researchers at the University of Bologna traced FFI back to an 18th-century Venetian doctor. The condition is caused by a genetic mutation that leads to prion accumulation in the thalamus, destroying the brain region that regulates sleep and autonomic functions. Unlike Creutzfeldt-Jakob disease, FFI specifically targets the thalamus, leaving it riddled with damage.
Silvano died within two years of his diagnosis, but his contribution has advanced understanding of the disease. A promising new drug offers hope, but the genetic nature of FFI raises ethical questions about whether at-risk family members should be informed of their potential fate.
