"A year on from the broadcast of our documentary A Different Brain, I have very fond memories of making the programme and of the experience of getting to know all the contributors. It takes a special kind of courage to allow someone into your life and trust them to tell your story - and even more so when you have gone through something as life-changing as a brain injury.

"Among the many moments that will stay with me are our visit to Natalie’s mum’s house in Wales for Natalie’s birthday; Dan’s mischievous sense of humour and his understandable sense of irritation at the restraints on his freedom (in particular, the meeting at which he said he wanted to leave Redford Court, which struck me as a brave statement on his part); Earl playing a song by Fetty Wap at high volume while his mum looked on in frustration; and of course the day we spent with Rob and Amanda and their wholly relatable sense of exasperation mixed with love as they talked over the kitchen table about their problems and tried to find a new footing for their relationship.

"I should also say how grateful I am to those who took part whose stories didn’t make the final cut - of which there were quite a few.

"It had been a dream of mine for many years to make a programme that touched on neurology and brain function. Having made it, what I came away with was a sense of the preciousness of life; the importance of taking care of each other; how one moment of inattention or plain bad luck can send the trajectory of one's existence careening off course; and the resources of stoicism and love people find in themselves to get through the most difficult of times. I don’t want for a second to minimise what coping with brain in jury entails. There is a great deal of sadness. Not all the stories we looked at involved people coming together. Families can drift apart. In some cases, I was struck by how slow the process of rehab appeared to be - and that even after years of help the gains could seem very small. But even in the darkest of stories there were redemptive qualities; sometimes just keeping going is a kind of miracle.

"I should also say that for all of the residents, it seemed to me BIRT was doing its best to provide safe and sensitive care. I appreciated their efforts and their willingness to put up with me and my BBC team. I am always curious to know what happens after the cameras leave, so I’m also grateful for this update. I send best wishes to all."
