Can mindfulness meditation change your brain differently if you're depressed?

When you practice mindfulness, you're often told to tune into bodily sensations. A new study looked at what's happening in the brain during this 'somatic awareness' in 86 people—some healthy, some with depression—who underwent mindfulness meditation training. The research found that the training changed how brain networks involved in body sensation and attention talk to each other, but in different patterns depending on whether a person was healthy or depressed. For the healthy group, changes seemed to involve more automatic processes, while for the depressed group, they involved networks linked to self-referential thought. Intriguingly, these specific brain changes predicted improvements in insomnia for people in both groups. It's important to note this is a snapshot of brain activity, not a clinical trial. The study didn't report key details like whether there was a control group, how large the effects were, or if the sleep improvements were substantial. The findings suggest a possible 'how' behind mindfulness, but don't yet tell us how well it works as a treatment.
