For the study, researchers analyzed brain scans of 801 people diagnosed with depression or anxiety. The people were scanned at rest, and again when they were engaged in different tasks intended to ...

Neuroscientists have identified a brain network that is nearly two times larger in the brains of people with depression. By analyzing people's brains over an extended period rather than at a ...

In the late 1980s, researchers identified a rare genetic mutation that leads to Alzheimer's disease, and yet drugs developed in response haven't slowed Alzheimer's progression nearly to the degree ...

She thinks instead that serotonin has such widespread effects in the brain that we may have trouble disentangling their direct antidepressant effect from other changes in our emotions or sensations ...

However, depression changes these dynamics as the disorder progresses. A single fMRI brain scan—a snapshot—can’t capture the brain’s trajectory over time. The team tackled these problems head-on. In a ...

In fMRI images, such as those the brain models shown here are based on, the salience network (shown in black) is twice as large in people with depression (right) than in those without (left). C ...

Depression: How brain scans helped predict long-term treatment outcomes. Activity in the brain’s cognitive control circuit could predict outcomes of depression treatments.

They think genetics, stress, and inflammation might play a role. It’s important to get help for your depression. That’s because repeat episodes seem to damage your brain more and more over time.

The new study appears to be the first to scan and compare brain areas during pregnancy and after childbirth and link the changes to postpartum depression, said Elseline Hoekzema, a neuroscientist ...
