AMYGDALA AND YOUR MOOD

Alen J SALERIAN MD

  Your amygdala may be the second most important brain region after prefrontal cortex for your mood and happiness.
 The larger your amygdala the greater the chances of your vulnerability to depression. And why? This pair OF almond shape centers mediate fear response. In essence they function as our radar to warn us of impending  external threats. Hence it makes sense that somebody with a sensitive amygdala would pick up more potential hostile threats wearing down her or his prefrontal cortex to a dysfunctional state. Then comes depression.
    Paradoxically people of abnormal and smaller amygdalas seem to be significantly more vulnerable to fibromyalgia and chronic pain. All of these findings are supported by neuroimaging studies.
  In essence what a good psychiatrist to do is to pay as much attention to your amygdala as to your environmental stressors if you're depressed.
