Amyloid beta pathology – protein deposits in the brain – might have been transmitted by contaminated neurosurgical instruments, suggests a new UCL-led study. Researchers studied the medical records of four people who had brain bleeds caused by amyloid beta build-up in the blood vessels of the brain. They found that all four people had undergone neurosurgery two or three decades earlier, raising the possibility that amyloid beta deposition may be transmissible through neurosurgical instruments. Amyloid beta is best known for being one of the hallmark proteins of Alzheimer’s disease.
