Rainer acknowledges that this seems miraculous.

When I first reported this story last summer, I kind of acknowledged that medical miracles do sometimes happen.

So could this be a medical miracle?

On a screen in a clinic in central London, there are slides showing cross-sections of brains.

In each hemisphere, a colon of purple light where the dopamine receptors are.

Dr Gratwick points and describes how these colons get smaller and dimmer as the disease progresses.

So it's not possible to have a brain scan showing the brain closing down and then six months later for that to have been reversed and to then see that patient have a normal brain scan?

In 2023, on a poster advertising all three of Raina Wynne's books, Penguin, her publisher, had written, Some people live to walk.

Raina and Moth walk to live.

It's confusing.

In her books, Raina is telling us he's better, but then Moth appears in videos, like the one for the PSPA charity, in which he's describing how difficult life is with his condition.

This video appeared on the PSPA website alongside videos of two other CBD sufferers who were diagnosed more recently than Moth, but who are obviously extremely disabled.

One appears wheelchair-bound and unable to speak.

The other struggles to articulate and walks with the aid of two sticks.

Moth's seated in an armchair by a window.

He's wearing a jumper and his signature cravat.

But then he gets up, puts on and zips up his jacket and then kneels down to tie his laces before striding out the door.

The PSPA have now taken down this video and cut ties with Moth and Rayner because, they said, there were too many unanswered questions raised by my investigation.

How does what you see in this video correspond to your experience of treating patients with this condition?

Last summer, I published the fact that nine neurologists who specialise in the condition had told me they didn't believe the disease could be reversed and that none of them had any experience of a patient with CBD surviving for 18 years.
