In the Netherlands, people with dementia can legally chose euthanasia but the debate is going back and forth there. When can dementia patients consent to euthanasia? The answer it turns out - is ethically very complicated and a Dutch doctor is now being prosecuted for performing euthanasia on a patient with advanced Alzheimer’s. In South Korea and the UK we hear from some of the most promising initiatives; and how a dementia friendly society is possible, with action not just from governments and NGOs but crucially from all of us.
