| Outline of Final Research Achievements |
This study aimed at elucidating the pathophysiological mechanisms and establishing its preclinical drug evaluation for novel pharmacotherapy in the neurodevelopmental disorder, by investigating the validity as an animal model in rats experienced with pharmacological stress (namely ACTH administration) during early postnatal period. The findings in this study suggest that the pharmacological stress during early postnatal period might produce the behavioral abnormalities such as cognitive impairments, anxiety-like and depressive-like behaviors in adulthood but not adolescent, with a critical developmental period. Those behavioral susceptibilities by pharmacological stress during early postnatal period after growth are possibly implicated in a dysregulation of the neuroendocrine system via hypothalamo-pituitary-adrenal (HPA) axis induced by adrenomegaly and dysfunction of the serotonergic/GABAergic neuronal systems in the raphe nuclei.
