Wissenschaftler identifizieren ein Gehirnsignal, das Aufschluss darüber gibt, ob Depressionstherapien wirken. Studie berichtet, dass ein spezifisches Gehirnnetzwerksignal zuverlässig vorhersagen kann, ob eine Person mit schwerer Depression auf eine Behandlung mit Antidepressiva anspricht.
Scientists identify a brain signal that reveals whether depression therapies will work

>A new [study](https://doi.org/10.1038/s44184-025-00182-2) published in npj Mental Health Research reports that a specific brain-network signal may reliably predict whether a person with major depression will respond to antidepressant treatment.
>Major depressive disorder affects millions worldwide, yet doctors still lack tools to determine which patients will benefit from antidepressants. Current treatment is largely trial-and-error, often requiring months before knowing whether a medication will work.
>Scientists have long suspected that the brain’s “default mode network”—a system active during self-reflection and rumination—plays a central role in depression. But until now, no study had convincingly shown that patterns within this network could predict treatment outcomes.
>The research team, led by Kaizhong Zheng and Liangjun Chen, set out to test whether communication between the medial prefrontal cortex (mPFC) and the posterior cingulate cortex (PCC)—two hubs of the default mode network—could serve as such a predictor. These regions are known to be involved in self-focused thinking and emotional regulation, both of which are disrupted in depression.
>To investigate this, the research team analyzed resting-state brain scans from a total of 4,271 participants across four datasets. The largest of these cohorts included 2,142 people diagnosed with major depression and 1,991 healthy individuals.
I’d be curious to know how or if there was any variance when it comes to different anti-depressants. Seems they had some other measurements, like if they’ve tried one(s) in the past or not, so has me wondering if they also had further categorization.
Either it seems like a interesting analysis, and I’m curious about what may come next.
