A woman in the United States has died from severe neurological damage caused by an abnormal protein that was injected into her without her knowledge nearly half a century ago.
Despite having no neurological symptoms for years after the injection, the 58-year-old patient began experiencing tremors and difficulty maintaining balance while walking. In the weeks that followed, she developed urinary incontinence, difficulty speaking, and abnormal breathing. After being hospitalized, she fell into a coma and later died, according to a case report published May 14 in the journal Emerging Infectious Diseases.
A repeat MRI performed during her hospitalization showed brain damage, and additional tests confirmed the presence of an abnormal protein known as a prion.
