There has been an incredible reaction to ‘Beti and David: Lost for Words’, an hour-long film broadcast this week on BBC One Wales (and still available on the BBC iPlayer).

Filmed over the course of many months, the film is a record of two people facing a terrible illness together. Since David’s diagnosis with Alzheimer’s, his long-time partner Beti has become his carer.

The reaction on Twitter, Facebook and elsewhere showed that the couple’s story struck an emotional chord with many.

David Parry-Jones was once one of the best-known faces in Wales – a news broadcaster and the voice of Welsh rugby during its glory days in the 1970s.

Beti George is still a broadcaster. Now she juggles her working life with looking after David and with campaigning for a better life for carers.

Through Beti’s experience the film reveals the challenges and frustrations faced by tens of thousands of carers across the UK, and questions the way society supports dementia carers.

Beti’s message is clear. ‘We need a revolution in dementia care’, she says.
