Shared Genetic Signatures Found Across Psychiatric Disorders
Summary: Researchers have uncovered shared biological mechanisms across major psychiatric disorders by analyzing postmortem brain samples from the dorsolateral prefrontal cortex. Instead of looking at gene expression broadly, they zoomed…
Blood Test Identifies Depression Risk in Teenagers
Summary: Researchers have identified nine blood-based microRNAs that are elevated in teens diagnosed with depression, offering a potential biomarker for early detection. These molecules, absent in adult depression, may signal…
Clues in Spinal Fluid Could Unlock Early FTD Diagnosis
Summary: Frontotemporal dementia (FTD), a common form of early-onset dementia, is often misdiagnosed due to its overlapping symptoms with psychiatric and neurological disorders. In a new NIH-funded study, researchers identified…
Tiny Gene Fragment Key to Memory Revealed
Summary: Researchers have discovered that a nine–amino acid microexon spliced into the DAAM1 gene is critical for memory formation, functioning exclusively in neurons. Deleting this microexon in mice resulted in…
Bigger Brains and Strong Immunity Linked to Longer Lifespans
Summary: New research reveals that mammals with larger brains and more robust immune systems tend to live longer lives. By studying 46 species, scientists found a clear link between maximum…
Two Key Signals Shape Brain Structure Early, Varying by Person
Summary: A new study has revealed how two morphogens, WNT and Sonic Hedgehog, act as molecular “traffic cops,” directing early human brain development. Using a custom device and stem cell-derived…
Can Brain Scans Tell Which Antidepressant Will Work for You?
Summary: A new study shows that brain connectivity patterns, especially in the dorsal anterior cingulate cortex, can help predict how patients with major depressive disorder (MDD) will respond to antidepressants.…
