European Union-funded research found that the beta-amyloid protein usually found in patients with Alzheimer's disease causes nerve cells to become more sensitive and excitable, which potentially could lead to an epileptic seizure. The finding "explains some of the link between Alzheimer's and epilepsy, adding a piece to the puzzle of what is happening in the brain during dementia," said Rebecca Wood, chief executive of the Alzheimer's Research Trust.
