Math for Primates co-host Nick Horton wrote a personal post on how he manages his depression. Here’s a bit on the neuroscience of depression:
The Prefrontal cortex is the part of your brain that deals with (among other things) the regulation of mood states. If it is atrophied, then your ability to deal with these tasks gets downgraded. This becomes particularly problematic given that without the prefrontal cortex running at full speed, you can’t dampen the negative emotions generated by the Amygdala. The amygdala is that part of your brain that deals with Fight or Flight responses. It is your brains Fear Factory. To add fuel to the fire, in depressed people the amygdala tends to be overactive.
Think of the Amygdala and the prefrontal cortex as the brains Yin and Yang. You need both to be strong and healthy to have a strong healthy brain that is in balance. Depressed folk ain’t in balance. Generally, the prefrontal cortex is responsible for saying, “Hey, Amygdala, I got your message. We’re cool here. No need to freak out, dude!” But, when your brain is broke (like mine), you can be flooded with negative emotional responses that can result in despair and overwhelming helplessness.
I found this part interesting as well:
Depression is so debilitating precisely because of the trick your mind plays on you. It tricks you into believing that how you feel is valid. This sparks a downward spiral of sadness that makes life impossible. The more you play into its tricks, the harder it gets to drag yourself out of it.
It gave me an idea. People of above average intelligent are known to be prone to depression, right? Could it be because smart people are better at finding reasons to be depressed, locking themselves into this downward spiral? Could people of average or less intelligence be better at talking themselves out of being depressed? I’m not sure how to test this hypothesis.
