Doctors have launched a clinical trial of a £100 blood test for Alzheimer’s disease in the hope of transforming diagnosis of the devastating condition in the NHS.

More than 1,000 patients with suspected dementia are being recruited from memory clinics across the UK to see whether the test leads to faster and more reliable diagnoses and better care for those found to have the disease.
