Summary:
- This article discusses a new study that found a simple blood test could predict the risk of developing dementia up to 25 years before the onset of symptoms.
- The test measures the levels of a protein called neurofilament light chain (NfL), which is released from damaged nerve cells in the brain. Higher levels of NfL in the blood are associated with an increased risk of developing dementia.
- This early detection could allow for earlier interventions and preventive measures to be taken, potentially delaying or even preventing the onset of dementia in some individuals.
