New research from Emory University is looking hopeful in speeding this process up. Researchers have been using a type of brain scans called PET scans to look at depression. Using brain scans for depression can help doctors pinpoint a treatment method to start with, increasing the likelihood of success.
Researchers report that brain scans can help identify which people will respond well to medication, and which might be better off with cognitive behavioral therapy — based on the amount of brain activity in certain regions.
The downside of this research? It’s in such an early stage that doctors likely won’t be able to use it in practice for many years.
