A blood test can predict dementia up to 15 years before symptoms start
Scientists have developed a blood test that can predict dementia up to 15 years before symptoms start with more than 90% accuracy.
The blood test could replace the expensive, time-consuming, and invasive tests currently used to diagnose dementia.
The identification of these protein biomarkers in the blood may also help guide the development of new drugs to slow or even reverse dementia. [ more ]
Early blood test to predict dementia is step closer as biological markers identified
Researchers have discovered biological markers for dementia in blood samples that can predict the risk of developing the condition over a decade before diagnosis.
A blood test that combines protein profiles with other risk factors can predict dementia with an estimated 90% accuracy 15 years before clinical confirmation. [ more ]
Johns Hopkins researchers make progress in developing blood test for psychiatric disorders
Johns Hopkins researchers are developing a blood test to detect brain changes associated with psychiatric and neurological disorders.
Extracellular vesicles, which contain mRNA, can provide information about what's happening inside the brain and could be used as a biological marker for detecting mental health issues. [ more ]
Alzheimer's blood test could hit the market in early 2024, researchers say
A new blood test developed by Resonant achieved 100% accuracy in identifying patients with Alzheimer's disease and those with mild cognitive impairment (MCI) who went on to develop Alzheimer's within five years.
The test works by detecting the presence of DNA released from neurons in the blood, indicating neurodegeneration.
Researchers are also working to apply this technology to other neurodegenerative diseases, such as Parkinson's and ALS. [ more ]
