Neuroscientists have amassed more evidence for the hypothesis that sticky proteins that are a hallmark of neurodegenerative diseases can be transferred between people under particular conditions — and cause new damage in a recipient’s brain.

They stress that their research does not suggest that disorders such as Alzheimer’s disease are contagious, but it does raise concern that certain medical and surgical procedures pose a risk of transmitting such proteins between humans, which might lead to brain disease decades later.

“The risk may turn out to be minor — but it needs to be investigated urgently,” says John Collinge, a neurologist at University College London
