My Lords, if I may, I will introduce a slightly discordant note, seeing as my name has been mentioned. I did not intend to speak, but I do think we need to be a little cautious about all this. I congratulate deeply the noble Baroness, Lady Greengross, on her remarkable work in this area, and nobody would doubt for a moment that everybody here is speaking in very good faith and for the best of purposes.
However, as medical practitioners, we must say that the placebo effect is very powerful and can cure people or improve their health in all sorts of ways and with all kinds of activities, not only dementia. Feeling well is not a simple matter. One concern is that we might spend much more money than we expect on these activities, without coming to the gist of why and whether they work, rather than something that substitutes for them.
I remind the House of one thing. For many decades, the health service supported homeopathy. Homeopathy—like cures like—has been widely used across the world and many people have great faith in it. There is actually no evidence at all that it has any genuine medical or chemical benefit; it is probably essentially a placebo effect. I am not suggesting for a moment that we should not look at exercise, music and all the other things, but I implore the Government; if we do this on the health service, there is a duty to ensure that research is done as well, because we must have a health service that looks at evidence-based medicine. That is fundamentally important.
