Wales Alzheimers Society

Wales has the worst diagnosis rate in the UK, with around 25,000 people thought to be living with the disease without a diagnosis and therefore without support.

Almost one in five people in Wales who notice symptoms of dementia are waiting more than six months before voicing their concerns, a leading charity has found.

Neil Norman, 93, is completing the challenge to raise money for the Alzheimer's Society, who helped his wife Anne before she died.
