What are the effects of glucocorticoids on learning?
Glucocorticoid hormones have strong effects on memory and learning in most animals ( Lupien and Lepage, 2001). Glucocorticoids are steroid hormones produced by the adrenal glands, and elevation in glucocorticoids is usually associated with stressful events. The most common glucocorticoid hormone in some mammals including humans is cortisol. Corticosterone, on the other hand, is the main glucocorticoid hormone in reptiles, birds, and other mammals (e.g., some rodents). Glucocorticoids (hereafter CORT) are essential hormones necessary for multiple physiological functions including regulation of metabolism and gluconeogenesis (e.g., Mizoguchi et al., 2004 ).
How do glucocorticoids affect the brain?
Glucocorticoid hormones play a pivotal role in countless processes in the brain at the molecular, cellular, physiological, and behavioral level. In view of their widespread influence, a tight control of glucocorticoid action is of great importance. Evidence has been accumulating that the action of glucocorticoid hormones is controlled in multiple ways. Overall, it seems that glucocorticoid action is checked at roughly three levels: (1) system physiological control of the concentration of circulating, biologically available glucocorticoid hormone and its access to the brain; (2) regulation of the expression of the main mediators of glucocorticoids, the mineralocorticoid receptor (MR) and the glucocorticoid receptor (GR); (3) control of MR and GR action at the effector level in terms of signaling, epigenetics, and genomics. This chapter reviews recent evidence that, at all three levels, regulatory control involves distinct epigenetic mechanisms including histone modifications, DNA methylation changes, and microRNAs, which are tissue-specific, context-dependent, and often redundant. It is clear from this assessment that, although there is still a long way to go, the elucidation of these epigenetic mechanisms in conjunction with the rapid developments in high-throughput technologies and bioinformatics will revolutionize the concepts on glucocorticoid action in the brain.
How do GCs affect the circadian clock?
Being under circadian control, GCs synchronize circadian clocks throughout the body. Since GRs are widely distributed in peripheral and central tissues, rhythmic GCs transmit SCN rhythmicity to target tissues. In cells, they bind to glucocorticoid responsive elements (GREs) in promotors, thereby imposing their own rhythms onto target genes and synchronizing cellular functions. Importantly, GREs are also present in the promotors of clock genes, 30–32 which enables them to reset and synchronize non-SCN circadian rhythms. 33 Interestingly the SCN itself has no GRs and is therefore insensitive to GC signals. 34 This complex interdependence of the stress and the circadian system impedes a precise separation of the two systems. Their intertwined nature becomes particularly clear when their combined influence on brain function and the development of psychiatric disorders is considered.
What hormones are released by the HPA axis?
8.2 ). For example, rhythmic BMAL1/CLOCK temporarily stimulates transcription of the steroidogenic acute regulator protein ( StAR ), the rate-limiting enzyme in steroidogenesis. 23 Consequently, GC synthesis is mainly restricted to times of high BMAL1/CLOCK in the adrenal. Additionally, the circadian release of each hormone (e.g., vasopressin from SCN) within the cascade directly controls the release of the following hormone (e.g., CRH). These oscillations are maintained throughout the entire cascade and result in rhythmic release of GCs from the adrenal gland. Moreover, GC signaling is gated by posttranslational interactions between clock proteins and GRs. Circadian proteins such as, CHRONO, REV-ERBα, and PER1 directly modulate GC/GR signaling. 24–26 In peripheral tissues, CRY1/2 promotes rhythmic repression of GRs, 27 and CLOCK decreases GR sensitivity by acetylation in the morning. 28,29 GRs are also present in all components of the HPA axis. In the anterior pituitary gland and the PVN, they mediate the GC feedback inhibition of the neuroendocrine cascade. 10 Thus the modulation of GR activity by clock proteins has an additional impact on the feedback inhibition of GC release and ultimately contributes to its daily rhythm.
Is the circadian clock bidirectional?
Importantly the connection between the circadian clock and the stress response is bidirectional: The circadian system controls HPA axis activity , while GCs serve as one of the most central internal synchronizers of non-SCN clocks. This tight interplay manifests in molecular interactions between both systems that affect the transcriptional, translational, and posttranslational level.
Which pathway is the glucocorticoid pathway?
The Glucocorticoid Pathway. Glucocorticoid hormones act along the hypothalamus–anterior pituitary–adrenal axis [11]. Corticotropin-releasing hormone is secreted from the hypothalamus gland to the anterior pituitary gland, which in turn signals for the production and release of adrenocorticotropic hormone (ACTH).
Does PTSD have glucocorticoid feedback?
Glucocorticoid stress hormones regulate both fear memory and extinction, and PTSD has been shown to be associated with deficient glucocorticoid feedback 54 and increased cortisol suppression in dexamethasone challenges. 55 These findings have been replicated in a variety of cases including in child abuse, 56 sexual-specific abuse, 57 natural disaster, 58 and holocaust survivor cohorts. 59 In PTSD, these alterations in glucocorticoid responses may influence consolidation or retrieval of trauma 60 by a lack of adaptive mechanisms in the brain, including BDNF, 30 and consequently maladaptive potentiation of trauma memory.
Why does glucocorticoid stop working?
This is of concern if the glucocorticoid is suddenly stopped because the adrenal tissues will not immediately begin producing glucocorticoids again. This is called acute adrenal insufficiency and symptoms include irritability, nausea, joint pains, dizziness and low blood pressure.
What is the effect of glucocorticoids on the immune system?
Glucocorticoids are a type of corticosteroid hormone that is very effective at reducing inflammation and suppressing the immune system. Inflammation is the way our immune system responds to harmful substances and trauma and is part of our healing process.
Can you take glucocorticoids long term?
For people who are taking glucocorticoids long-term, extra doses of glucocorticoids should be given during times of acute stress, such as severe infection or surgery, to mimic the cortisol surge that is normally produced by the body during particularly stressful events, otherwise healing may be delayed or incomplete.
Can glucocorticoids cause Cushing's syndrome?

Glucocorticoids have been associated with a number of side effects including: 1 Agitation and irritability 2 Blurred vision 3 Cataracts or glaucoma 4 Difficulty concentrating 5 Dizziness 6 Facial hair growth in females 7 Fast or irregular heartbeat 8 Fluid retention 9 A headache 10 High blood pressure 11 Increase in blood sugar, cholesterol, or triglyceride levels 12 Increase in the risk of gastric ulcers or gastritis 13 Loss of potassium 14 Osteoporosis due to a suppression of the body’s ability to absorb calcium 15 Reactivation of latent tuberculosis 16 Shortness of breath 17 Sleeplessness 18 Weight gain.
Can glucocorticoids cause insomnia?
Evening dosages of glucocorticoids should be discouraged as they can cause insomnia. Instead, glucocorticoids are normally taken just once a day, or if taken twice a day, they should be dosed in the morning and again at noon. Because glucocorticoids suppress the immune system, they increase the risk of infection.
