Polyvagal Theory and Hope In Healing from Childhood Trauma
Polyvagal theory emphasizes the evolutionary development of two systems: the parasympathetic nervous system which is ultimately connected to the vagal nerve and the sympathetic nervous system. Each has its own function, and cause the body to react differently before, during, and after a traumatic or stressful event. If these two systems become damaged from excessive and recurrent trauma, a break down occurs and mental illnesses such as CPTSD and anxiety disorders may result.
