The Evolution of THIS Troubled Mind
April 29th, 2008, 4:12 pm by craig@depressionisms.comMind Hacks has a post on Evolution of a Troubled Mind that continues the theme set in a recent edition of ABC Radio National’s All in the Mind. Natasha’s show is always awesome, but I’ve been slack and not listened to my podcasts or her latest episode yet. Still, what Mind Hacks wrote resonated somewhat with an experience I had yesterday…
I was feeling depressed with the urge to do ’something’ at a time when everything around me had negative connotations, so I sat on the floor.
Not happy with the novelty of sitting on the floor - while not something I normally do - I then felt the need to to sit in the cupboard before stopping myself and thinking that’s completely mad, even though I was alone and could be completely mad.
At that moment the thought occurred that the unrelenting urge to do something novel, felt like a flight survival instinct. Something I’ve been doing my entire life. That my innate desire to do something ‘differently’ takes hold in order to present myself with a novel concept, or way of looking at things from a different perspective and one more enticing; hence a new environment to become absorbed in. Possibly why I get bored and depressed so quickly.
When I think about this and the way in which we learn and store memories, the more I’m convinced that these tendencies are evolutionary. I say this because I keep reading about glucocorticoids, stress, amygdala enhancement and the strength of emotive episodes that result from those contributing factors. There’s also the known inhibition of orexin-A gene expression and concentration and memory formation problems that result when I get depressed and sleep disturbed.
Prior to my recent depressive episode I had consumed large amounts of glucose and milk chocolate foods and initially later felt a strong desire to seek out company; something I hadn’t done for a while, especially on a high fruit & veg fructose diet.
I do know that fruit flies choose to procreate over preserve when exposed to high protein diets… and that mothers with high calorie intake and variety are more likely to have boys. Three in this family! Calorie restriction is also implicated in life extension, not to mention there’s an antidepressant that life extends working through calorie restriction. Fluoxetine from memory, but maybe not.
I also know that my mother was very anxious when she had me because of a prior miscarriage and her own anxiety tendencies, and that in rats this affects offspring for generations.
A very stressful early life with school and dad, and I now find myself very susceptible to social and environmental stress. With what I know now about gene expression as a result of social stress, and traits that are passed on, that it certainly indicates to me there’s an evolutionary element to mental illness.
Survival until a time when the environment is seen to be appealing and conducive to procreation…
I’m reminded of another study about ants that play-dead that are 4 times more likely to survive an attack from an outside colony…
Most of the time when the environment I find myself in makes me feel depressed, I play-dead and feel like I don’t exist and just want to be left alone or find a new environment to explore.
My problem is I feel like I’m under constant attack in every environment and the reward to participate is non-existent.
