Yes he is. But on another note - we make a Will or Lasting Power of Attorney when we have capacity. We make sure our families are looked after and protected on our death. Is there any reason a form could not be devised by the Court of Protection/Law Society to agree to offer ourselves to medical science when we lose all capacity due to dementia/Alzheimer? We can leave our bodies to medical science for research once we have died. We can donate our organs on death to save life. So why not ourselves whilst alive for the benefit of medical science. There would need to be safeguards put in place of course but this would not be beyond the wit of man. The benefits would be incalculable and there can be very few of us who have not had or will have a family member or friend touched by this dreadful illness. Something needs to be done to encourage research which is hugely expensive. Without testing how can we advance. This is not one of the more popular causes but is just as important. We are all, and our children and grandchildren, going to be effected on way or another by dementia, and we need to start sooner rather than later before it's too late.
I agree that delaying the onset of the Amyloid/Tau protein dementias is the key. Increase the age of symptom onset from 80 to 85 years - for example - would mean most people not reaching the point of significant loss of “quality of life” before the natural point of death. This would massively reduce the numbers needing full time residential care and also burden of caring responsibility for offspring often themselves over the age of 60. A very well thought through synopsis of the subject.
