An Alzheimer's Society supporter is hoping to raise £100,000 by walking 5,000 miles around the UK.
Philip Williams, 43, is walking around the English, Welsh and Scottish coasts as a tribute to his mother, Margaret, 82, who has Alzheimer's.
Starting his extensive trip in Poole, over the past few months he has journeyed through Poole, Portsmouth, Padstow and Falmouth and is planning to celebrate St David's Day in Swansea on the Welsh leg of his tour.
"Since my mum was diagnosed with dementia seven years ago I have come to realise just how important Alzheimer's Society is. It has provided so much invaluable help and support to me, my mum and my whole family," he told the Alzheimer's Society.
Meanwhile, researchers from Kuakini Medical System in Honolulu have found that dementias are commonly misdiagnosed as Alzheimer's disease.
It was found that around half of the autopsies of those diagnosed with the condition fail to confirm that the patient had Alzheimer's disease, with characteristics of the condition not present.
