Your brain on sugar: What the science actually says

Sugar triggers dopamine "hits" in the brain, making us crave more of it. Sugar also disrupts memory formation.

Brain scans help shed light on the PTSD brain, but they cannot diagnose PTSD

The brain can do a lot, but it is vulnerable, especially to traumatic events. Over the years, researchers have learned the unique ways in which it is damaged by experiencing or witnessing trauma.
