As mentioned, biological factors (or vulnerabilities) usually have to be in place for an anxiety disorder to manifest because of advancements in genetic research, we now know that many diseases and disorders have a genetic component.

Over sensitive fear response can be explained in terms of the functioning of the autonomic nervous system in some individuals there may be high levels of arousal of the ans, which leads to increased amounts of adrenaline. Biological explanation of phobias genetic factors one biological explanation for the cause of phobic disorders suggests that we can relate it back to our genetics this theory values the ‘nature’ side in the nature vs nurture debate.

Genetics certainly account for some of the biological differences between people, but our biological make-up also accounts for the similarities among people one such similarity is the human response to fear.

Couple of paragraphs of commentary explaining, with reference to these examples and the genetic data we have also looked at, the extent to which phobias can be explained wholly in biological terms liebowitz et al (1985) stressed.
