Keloids tend to have a genetic component, which means one is more likely to have keloids if one or both of their parents has them. However, no single gene has yet been identified which is a causing factor in keloid scarring but several susceptibility loci have been discovered, most notably in Chromosome 15.
The term ‘hysteroid dysphoria’ was first introduced into the field of psychiatry by Klein and Liebowitz in 1979. Their pioneering work derived from research conducted on a subgroup of depressed patients, reporting a consistent pattern of "repeated depressed moods in response to feeling rejected" among the participants.
Dr. Alexiades says that she believes keloids behave like benign tumors of the skin; the fibroblasts—the cells that make collagen—are proliferating and producing collagen out of control in keloids.
The idea that individuals vary in their sensitivity to their environment was historically framed in diathesis-stress [4] or dual-risk terms. [5] These theories suggested that some "vulnerable" individuals, due to their biological, temperamental and/or physiological characteristics (i.e., "diathesis" or "risk 1"), are more vulnerable to the adverse effects of negative experiences (i.e., "stress ...

Reduced affect display, sometimes referred to as emotional blunting or emotional numbing, is a condition of reduced emotional reactivity in an individual. It manifests as a failure to express feelings either verbally or nonverbally, especially when talking about issues that would normally be expected to engage emotions.
Sensory processing sensitivity (SPS) is a temperamental or personality trait involving "an increased sensitivity of the central nervous system and a deeper cognitive processing of physical, social, and emotional stimuli". [2]
For example, when one tastes a potentially nutritious stimulus, the connectivity between the insula and a feeding network including the hypothalamus, ventral pallidum, and striatum is greater than when tasting a potentially harmful stimulus. These results support the existence of an integrated supramodal flavor system in the anterior ventral ...
