Blood Clues to Long-COVID Brain Fog Discovered

Researchers have discovered two blood biomarkers that could predict cognitive deficits, including "brain fog," up to a year after a COVID-19 diagnosis. The study analyzed data from over 1,800 hospitalized patients and identified high levels of fibrinogen and d-dimer, proteins linked to blood coagulation, as being highly correlated with cognitive issues.

Two-Step Blood Test Sharpens Alzheimer’s Diagnosis

Researchers have developed a two-step workflow using a new blood-based p-tau217 biomarker to improve the accuracy of Alzheimer's Disease (AD) diagnosis. The first step uses a diagnostic model that combines plasma p-tau217 with age and the APOE e4 gene to identify high-risk patients.

Blood-Based Markers May Reveal Alzheimer’s Disease Ten Years Before Symptoms Show

A new blood test can detect the GFAP protein at elevated levels in blood samples up to ten years before symptoms of Alzheimer's disease are first noticeable in those with an inherited form of the neurodegenerative disorder.

A Mother’s Blood May Carry the Secret to One Type of Autism

Maternal autoantibody–related autism spectrum disorder (MAR ASD) is marked by specific maternal antibodies that react to certain proteins in the fetal brain. Examining the plasma of expecting mothers, researchers found mothers with reactivity to one of the nine MAR ASD patterns were eight times as likely to have a child diagnosed with autism.

Promising Alzheimer’s Marker in Blood Prompts Warning About Brain-Boosting Supplements

Elevated levels of PHGDH in the blood could signal the earliest stages of Alzheimer's disease. Researchers caution older adults against using "brain-boosting" supplements that contain serine due to its link to PHGDH. As PHGDH is a key enzyme in serine production, elevated PHGDH levels results in increased serine levels in the brain.

New Blood Biomarker for Predicting Dementia Before Symptoms Develop

Measuring blood levels of P-tau181 may allow doctors to diagnose Alzheimer's before the onset of symptoms. Elevated levels of P-tau181 in the blood were associated with greater amyloid beta accumulation in the brain and outperformed two other biomarkers in predicting signs of amyloid beta in brain scans.

Genetic Link Between Routine Blood Test Results and Mental Health Disorders Discovered

Researchers identified a genetic correlation between blood biomarkers and a range of mental health disorders. The study provides evidence some substance measures within the blood may be involved in the cause of mental illnesses. For example, immune system proteins may be involved in the development of depression, schizophrenia, and anorexia.
