A woman in the U.S. has died from severe neurological symptoms that were caused by an abnormal protein — which she was unknowingly injected with nearly 50 years earlier.
Having shown no neurological symptoms in the decades since the injection, the 58-year-old recently began experiencing tremors and changes in her ability to balance while walking. In the following weeks, she developed urinary incontinence, difficulty speaking and abnormal breathing. After being admitted to hospital, she entered a coma and later died, according to a case report published May 14 in the journal Emerging Infectious Diseases.
