Can you tell us a little bit more about Esme's umbrella and also about Charles Bonnet syndrome? Because I know over the years you've worked really, really hard to raise awareness of the condition.

Yes, I have, absolutely.

Ten years last November was when I started.

My charity is called Esmis Umbrella, in memory of my mother, and it was her experience of Charles Bonnet syndrome at a time when nobody knew what it was, nobody was talking about it, there was no support, that finally made me, after she had died actually, decide that I really needed to do something.

So Esme's Umbrella was launched at the House of Commons in 2015 as a campaign to raise awareness, to find ways to support people who develop the condition and to inspire research.

And then in 2021, I turned it into a proper charity.

Charles Bonnet Syndrome is a condition which can develop in a child, a young person or an adult It causes vivid, silent visual hallucinations, which can range from very simple images, words, patterns, musical notes, maps, all the way through to people and whole scenes.

Because I think Judith, earlier you mentioned that this is still something we don't really have a lot of information about.
