We assess currently available biological markers to query their validity for aiding in the diagnosis of major depression. To date, however, none of these markers are sufficiently specific to contribute to the diagnosis of major depression.

Some of the maternal traumatic stress has significant impact on most important microenvironmental stimuli are neurodevelopment. The development of the human receptor-mediated signals from neurotransmitters brain continues beyond birth and its development and hormones, which act as morphogens. That is remains vulnerable to the abnormal patterns of why the stress response is extremely important for neurotransmitter and hormone activity associated brain organization (Perry and Pollard 1998).
