It’s not just a matter of semantics — if researchers can trace addiction’s root causes to an actual medical malfunction in the brain, perhaps that disease could be directly treated. Who am I to disagree with a “four-year process with more than 80 experts actively working on it?” Their result? Addiction is a “chronic brain disorder and not simply a behavioral problem.” I suppose if we wanted, one could argue that all mental disorders can be viewed as “brain disorders” and not “simply behavioral problems.”...

The appeal of puzzles goes far deeper than the dopamine-reward rush of finding a solution. The very idea of doing a crossword or a Sudoku puzzle typically shifts the brain into an open, playful state. There are different ways to solve a puzzle: an analytical way of trial and errors and an “insight” or creative way.  Recent neuroimaging studies looked at what happens in the brain of people preparing to solve a puzzle. Results suggest that a particular signature of preparatory activity, one that is strongly correlated with positive moods, can be observed in people’s brains who are more likely to solve puzzles with sudden insight than with trial and...

A new study reports that high levels of brain activity in an emotional center called the amygdala reflect patients' hypersensitivity to anticipation of adverse events. At the same time, high activity in a regulatory region known as the anterior cingulate cortex is associated with a positive clinical response to a common antidepressant medication. The study will appear in an upcoming issue of the American Journal of Psychiatry. For individuals with anxiety disorders, the anticipation of a bad outcome can be worse than the outcome itself, says Jack Nitschke, assistant professor and clinical psy...

"Such biomarkers that identify who will benefit from a new class of antidepressants could someday minimize trial-and-error prescribing and speed delivery of care for what can be a life-threatening illness," said Carlos Zarate, MD, of the National Institute of Mental Health (NIMH), Mood and Anxiety Disorders Program. In the new study at the National Institutes of Health in Bethesda, MD, depressed patients showed increasing activity in a mood-regulating hub near the front of the brain while viewing flashing scary faces - the more the increase, the better thei...

In addition to functional abnormalities, these results suggest that structural abnormalities of the ACC contribute to the pathophysiology of panic disorder. (Link added; ed.) Source...

This is the first time I've seen that relates the stress of poverty to brain changes. This needs to be a target for prevention policy. Blogs Scientific American Community "The authors recruited 100 middle-aged volunteers from a Pennsylvania community registry and acquired three important measures from each. First, participants provided information that qualified as an objective indicator of personal and community socioeconomic status (for example, educational attainment and household income). Second, they received the MacArthur Scale of Subjective Social Status. In this scale, participants were presented with a 10 step "social ladder" and asked to place an "X" on the step the...
