A study published in JAMA today revealed that a blood test was about 90% accurate in identifying Alzheimer's in patients with memory issues, outperforming cognitive tests and CT scans interpreted by doctors, which were only 73% and 61% accurate, respectively. The research, presented at the Alzheimer's Association International Conference, suggests that routine blood tests for cognitive impairment could become common in primary care. However, experts stress that blood tests should be part of a comprehensive screening process and are currently recommended only for symptomatic individuals. The new blood test, focusing on the protein tau, could potentially revolutionize Alzheimer's diagnosis and treatment, especially if confirmed in diverse populations. Source: Oman News Agency
