Actually a real case in a US state that has death with dignity laws. One requirement of the law is that you can make the decision only when in a very bad state (high pain, etc as certified by a doctor). And only the person can make the decision. Not a loved one. A woman diagnosed with Alzheimer's couldn't make use of this because it'll only get bad when she loses much of her mental faculty. But by that point she is not mentally fit to make that decision. She filed a lawsuit and eventually moved to Europe to get her death with dignity there.
