Editing Panic attack (section)

=== Amygdala dysfunction theory ===
The amygdala in the human brain has several distinct sections that are responsible for our fear response. This theory suggests that problems in any of these brain areas or the connections between them could lead to excessive fear responses, like panic attacks. Studies have shown that in both animal and human subjects with a history of panic attacks, the amygdala is hyperactive with decreased volume when compared to the control. Another role the amygdala may play in panic attacks is decreased inhibition of amygdalar activity (i.e. the amygdala is not being shut down like it normally should), leading to increased levels of anxiety. A link between childhood traumatic experiences, as well as genetic abnormalities, has been found in those with a dysfunctional amygdala.<ref name=":12" />
