Research provides new evidence that generalized anxiety disorder (GAD) and depressive disorder (DD) have distinct patterns of brain activity. Machine learning analysis of EEG data reveals signature brain features that may enable more accurate diagnosis. Key Facts: DD showed increased beta band power and complexity compared to GAD Brain network connectivity was altered in both …
Researchers have discovered that a common soil bacterium called Mycobacterium vaccae (M. vaccae) may help reduce stress, anxiety, and inflammation in the brain. Key Facts: M. vaccae is a naturally occurring bacterium found in soil, mud, and water. It is considered harmless to humans. When heat-killed M. vaccae is injected into rats, it reduces stress-induced …
Researchers developed a new gene editing technique that reduces anxiety in mice. The technique uses CRISPR technology to edit a specific gene in the brain called HTR2A. Editing this gene leads to lower levels of anxiety behaviors in tests with mice. This research demonstrates the potential of using gene editing tools like CRISPR to precisely …
