The controversial theory that the “seeds” of Alzheimer’s disease may have been transmitted between patients during surgical procedures involving the use of donated human tissue has been supported by the discovery of new evidence. Scientists have found a link between patients who received nerve-tissue grafts several decades ago and the presence of a protein in the brain that is normally seen in the earliest stages of Alzheimer’s disease. The study supports findings published last September suggesting that people who had been injected with human growth hormone when they were children were harbouring the same seeds of Alzheimer’s disease at the time of their death several decades later.
