Summary: Carriers of recessive gene mutations, long thought to be unaffected, may actually face subtle disadvantages, including more medical issues, shorter educational attainment, and reduced reproductive success. A study of over 300,000 individuals reveals that people who carry recessive genes for intellectual disability are especially impacted, despite having only one mutated gene copy. These carriers … Read more
Summary: A new study comparing long COVID patients with fully recovered individuals has found that those with persistent cognitive symptoms, like brain fog, show higher brain inflammation and reduced capacity to handle stress. The study revealed lower levels of nerve growth factor and elevated inflammatory markers in the long COVID group. Despite performing similarly on … Read more

New OHSU research reveals an important role in brain function involving an abundant, but often-ignored, star-shaped type of glial cell known as astrocytes. Scientists say the discovery suggests new approaches to treat or prevent neurodegenerative conditions like Alzheimer’s or Parkinson’s diseases. (OHSU/Christine Torres Hicks) An often-ignored type of cell in the brain plays a dynamic … Read more
Summary: A newly identified biomarker, an enlarged salience network in the brain, could dramatically change how depression is detected and treated. This network, responsible for regulating attention and switching between mental states, was found to be consistently larger in people with depression, regardless of symptom severity or treatment history. Crucially, the expansion appears to predate … Read more

Summary: Researchers have identified a biomarker in spinal fluid that can detect Parkinson’s disease in its early stages with over 90% accuracy. Using a patented immuno-infrared sensor (iRS) technology, they measured the misfolding of the alpha-synuclein (αSyn) protein, a key driver of the disease. Early diagnosis is crucial, as clinical symptoms usually appear only after … Read more
