Simple blood tests for dementia to be trialled in NHS

5m project launched with aim of having reliable tests within five years to provide quick diagnosis

Scientists are to begin piloting simple blood tests for dementia that could revolutionise detection of the disease and within five years lead to people being diagnosed in seconds by the NHS.

Currently, getting a formal diagnosis in the UK relies on mental ability tests, brain scans or invasive and painful lumbar punctures, where a sample of cerebrospinal fluid is drawn from the lower back.
