NEUROBIOLOGICAL BASIS FOR PTSD ILLNESS Briefly explain the neurobiological basis for PTSD illness.

Post-traumatic stress disorder is described as a mental health condition that is caused by experience associated with terrifying events. More often than when one witnesses or experiences a terrifying event it is likely that such events can lead to development of wide range of mental disorders but the most common is the post-traumatic stress disorder (PSTD). Studies have shown that the neurological basis for this condition encompasses neuroanatomical basis, neuroendocrine basis and neurochemical basis(O'Connor & Zachariae, 2015). It worth noting that human body can respond to various types of stressful events and for effective responses to be generated by the body, it is the exclusive role of the neuroendocrine systems under the influence of the hyponatremic-pituitary-adrenal axis. During stressful events, neuroendocrine responds by initiating the secretion of corticotropin-releasing hormone (CRH) from the hypothalamus which un turns leads to secretion of adrenocorticotropin hormone (ACTH) to the blood stream along with the release of thyroid, cortisol, as well as catecholamines hormone to initiate changes that promote flight or fight to the identified stress.
