Overview

• Thousands of Britons to participate in landmark trials for a new blood test that could significantly improve Alzheimer's diagnosis rates.
• The tests, costing about £100 each, seek to identify early-stage proteins linked to Alzheimer's and other dementias, potentially speeding up diagnosis.
• Over 900,000 people in the UK currently live with dementia, with the trials aiming to address the nation's 'shocking' diagnosis rates.
• Researchers hope the blood tests will facilitate earlier treatment with a new class of drugs, enhancing their effectiveness.
• The trials are backed by £5 million from the People’s Postcode Lottery, with results potentially ready for NHS use within five years.
