US scientists say a blood test can predict the onset of Alzheimer's disease with 90% accuracy.

Experts said the results needed to be confirmed, but such a test would be "a real step forward".

Vivien Hill, whose late mother was diagnosed with early-onset dementia at 61, said she would take the test.

She told BBC Radio 5 live's Chris Warburton: "It means I could plan for my future... and potentially I could be in on those early trials."
