Scientists say test could replace a costly brain scan or painful lumbar puncture and enable earlier detection of disease

If validated, the test could enable faster diagnosis of the disease, meaning therapies could be initiated earlier.
Alzheimer’s is the most common form of dementia, but diagnosis remains challenging – particularly during the earlier stages of the disease.
