For decades, researchers and doctors have believed that a patient can develop Alzheimer's when there is a history of cranial trauma, genes or cardiovascular problems; However, a study reveals that this disease can be transmitted in a surgery.

To reach this result, experts from the University Hospital Zurich and the Institute of Neuropathology performed a 21-person autopsy, which years before his death had been subjected to a surgical graft of dura mater (membrane that covers the brain).

Who you are?

The analyzes were compared with that of other individuals who, like the first group, had died of Creutzfeldt-Jokob disease, but had not received a graft.

This supports the theory that the Alzheimer's it can be transmitted; but how?

It is believed that the amyloid-b protein is the cause. This can act as a trigger for dementia; that is to say, the grafts (that contain the protein) when being transplanted contaminate the healthy tissues.
