361:) have been studied closely in many scientific studies, whose results indicate a strong link between the disorders, with a disproportionate amount of post traumatic stress patients reporting recurring feelings of derealization and depersonalization (up to 30% of those with the condition) in comparison to the general populace (only around 2%), especially in those who experienced the trauma in childhood. Many possibilities have been suggested by various psychologists to help explain these findings, the most widely accepted including that experiencing trauma can cause individuals to distance themselves from their surroundings and perception, with the aim of subsequently distancing themselves from the trauma and (especially in the case of depersonalisation) their emotional response to it. This could be either as a deliberate coping mechanism or an involuntary, reflexive response depending on circumstance. This possibly not only increases the risk of experiencing problems with derealization and its corresponding disorder, but with all relevant dissociative disorders. In the case of childhood trauma, not only are children more likely to be susceptible to such a response as they are less able to implement more healthy strategies to deal with the emotional implications of experiencing trauma, there is also a lot of evidence that shows trauma can have a substantial detrimental effect on learning and development, especially since those who experience trauma in childhood are far less likely to have received adequate parenting. These are factors proven to increase susceptibility to maladaptive psychological conditions, which of course includes dissociative disorders and subsequently derealization symptoms.
330:, subsequently seeming difficult or impossible to ignore. This type of anxiety can be crippling to the affected and may lead to avoidant behavior. Those who experience this phenomenon may feel concern over the cause of their derealization. It is often difficult to accept that such a disturbing symptom is simply a result of anxiety, and the individual may often think that the cause must be something more serious. This can, in turn, cause more anxiety and worsen the derealization. Derealization also has been shown to interfere with the learning process, with cognitive impairments demonstrated in immediate recall and visuospatial deficits. This can be best understood as the individual feeling as if they see the events in third person.

This "blocking effect" creates a discrepancy of correlation between one's perception of one's surroundings during a derealization episode, and what that same individual would perceive in the absence of a derealization episode.

354:). There is a similarity between visual hypo-emotionality, a reduced emotional response to viewed objects, and derealization. This suggests a disruption of the process by which perception becomes emotionally colored. This qualitative change in the experiencing of perception may lead to reports of anything viewed being unreal or detached.
