A study by Lanius et al. was conducted to cast light upon why many with individuals suffering from posttraumatic stress disorder (PTSD), including those suffering from complex-PTSD, often find it excruciatingly uncomfortable every time the rules of social etiquette compel them to make eye to eye contact with another human being (I, myself once attempted to circumvent this
Three critical brain regions that may be adversely affected by significant and chronic childhood trauma are :
1) The thalamus
2) The amygdala
3) The hippocampus
Below, I will briefly describe the main functions of each of these three crucial regions of the brain, together with providing a summary of the damage they may sustain to their development due early adverse experiences.
1) Possible Adverse Effects Of Childhood Trauma On The Development Of The Thalamus :
The thalamus is the part of the brain
We have already seen in other articles that I have posted on this site that significant and protracted childhood trauma can physically damage the developing brain and have an adverse effect upon the body’s physiology as a whole. In particular, it can:
– effect the way that the prefrontal cortex, amygdala and hippocampus interact
which, in turn, can:
– lead to massive over-production
Research on the brain carried out by McCarthy suggests that if a child is subjected to significant, chronic stress, particularly when the cause of this stress is unpredictable (eg due to a hostile, abusive, unstable parent prone to random explosions of terrifying rage), s/he may develop brain inflammation.
This is a recent finding – until not long ago, the prevailing wisdom was that brain inflammation could only be caused by physical damage to the brain, not psychological
