The disease is a particularly complicated one to crack, due in part to the fact that its effect on humans is it is nearly impossible to replicate in lab animals; its slow progression and , according to Eric Karran at the Alzheimer's Research UK, "The disease seems to be present in people's brains maybe 15 years prior to... suffering symptoms."
