A lack of sleep, chronic stress at home, poor nutrition--all these factors can activate the brain's stress response system
, Desautels says.
The element of depression may increase in cats with the increase of threat either related to any conflict (Moesta and Crowell-Davis 2011) or fetal developmental stress response system
(Westropp et al.
Trauma can over-activate a growing brain's stress response system
Decades ago, Hans Selye demonstrated that chronic activation of the stress response system
resulted initially in hyperactivity of the physiological stress response.
They investigated the role of hCLOCK in the hypoxia-oxidative stress response system
at the biochemical level.
The purpose of this article is to describe the functioning of the stress response system
of the brain and to review literature pertaining to the impact of early life stress on the development of the stress response mechanisms.
If they're living in a threatening enough environment, their stress response system
, their sympathetic nervous system, their hormonal system and their immune system can all be activated searching for the threat.
The findings suggest that dementia may involve in part a failure of the brain's stress response system
Children in those situations who do not have adequate adult support can develop a prolonged activation of the stress response system
, which can disrupt the brain's development and increase the risk for stress-related disease and cognitive impairment, even into adulthood.
Recent research suggests that these hormonal changes are the trigger for the direct stimulation of reduced growth in response to environmental stress; this stress response system
is basically activated by the low availability of a resource.
One of the most valuable aspects of the stress response system
is its feedback loop; when the threat subsides, the parasympathetic system returns the body to homeostasis, and the effects are reversed.
Another pathway that also has been implicated in alcohol abuse, and particularly in the transition to alcohol dependence, involves two stress-response systems, the hypothalamic-pituitary-adrenal (HPA) axis and the extra-hypothalamic corticotropin-releasing factor (CRF) stress response system
, which mediate the interaction of psychosocial stress and early alcohol use.
