Recognizing these prodromal features offers a vital chance for timely support,...
Prion Disease: Early Signs, Diagnostic Innovations, and Management Plans
Prion diseases are a group of rare but devastating brain disorders caused by misfolded prion proteins that trigger a chain reaction, converting healthy prion proteins into the abnormal form. As these misfolded proteins accumulate, they create sponge-like holes in brain tissue, leading to rapid neurological decline. Although prion diseases—such as Creutzfeldt-Jakob disease (CJD), fatal familial insomnia, and Gerstmann–Sträussler–Scheinker syndrome—are...
