New Insight Into How Brain Stimulation Eases Major Depression

For the first time, researchers understand what happens to the brain when patients with treatment-resistant depression receive repetitive transcranial magnetic stimulation (rTMS). Using functional magnetic resonance imaging (fMRI), they showed that rTMS induces widespread alterations in functional connectivity in brain regions involved in emotion and motor control. ‘How does rTMS work?’ is one of the … Read more

Long-term Brain Health Is Impacted by Severity of COVID-19

The study covered in this summary was published in medRxiv.org as a preprint and has not yet been peer reviewed. Key Takeaways Using resting-state fluctuation amplitudes (RSFA) from functional MRI, follow-up of hospitalized patients with COVID-19 shows that the severity of acute COVID-19 is associated with chronic cerebrovascular consequences for cognitive function and mental well-being. … Read more
