Q

Mild stress: what happen?

A
  • desensitize circuits –> experience based resilience;
    • 5HT ↑’s availability of BDNF, preventing or reversing neuron loss
    • hippocampus vulnerable to these losses

Q

Chronic stress: what happens?

A
  • turns off BDNF genes –> ↓creation/maintenance of neurons & connections –> synapse loss or apoptosis (loss of the whole neuron)
  • Stress and cortisol exposure decrease BDNF expression and can cause hippocampal atrophy, similar to atrophy that occurs in depression

Q

What is BDNF?

A
  • Brain Derived Neurotrophic Factor
  • A protein; member of neurotrophins – r/t NGF or nerve growth factor
  • Found in brain & periphery
  • Supports neuron survival, encourages growth/differentiation of new neurons and synapses.
  • Active in hippocampus, cortex, basal forebrain – r/t learning, memory, higher thinking
  • Neurotrophins help to stimulate and control neurogenesis and BDNF is very active
  • In animal models, exercise increases BDNF secretion in hippocampus

Q

Cortisol vs corticosterone

A

Cortisol is the predominant glucocorticoid in humans (and is produced in the adrenal zona fasciculata), whereas corticosterone is less abundant in humans, but is the dominant glucocorticoid in rodents (in humans it is produced in the zonae fasciculata AND glomerulusa).

A

process of achieving stability (homeostasis) through adaptive physiologic or behavior change. Good in short term. Possibly damaging if not “shut off”

Q

Stress response: what happens when we perceive a threat?

A

Thalamus → Amygdala. Lateral amygdala receives sensory input (ex: fear) → to central nucleus of amygdala → output activates HPA axis & sympathetic ns

  • Hypothalamus secretes:
    • CRH → triggers ACTH release from anterior pituitary → triggers stress hormone release (glucocoritcoids, i.e. cortisol) from adrenal cortex
    • β-endorphin (mitigates pain reduction) → stimulates epinephrine release from adrenal medulla;
    • AVP also released from hypothalamus
  • Hippocampus has adrenal steroid receptors:
    • Type I: mineralocorticoid; Type II: glucocorticoid
    • Produces excitation, if prolonged can lead to excitotoxicity/damage

Q

Describe the hormonal cascade involved in HPA activation

A
  • Corticotrophin releasing hormone (CRH) secreted in hypothalamus →
  • AP, which releases ACTH →
  • Through bloodstream to adrenal cortex, which releases glucocorticoids (cortisol) →
  • Cortisol feeds back, slowing release of ACTH & CRH

Q

HPA response: when does it occur in response to stress?

A

approx. 5 min after event
* from Hypothalamus (PVN) → CRH → Vasopressin (AVP) → pituitary → ACTH → Adrenal cortex → cortisol
* response: PNS –> SNS –> HPA*

37
Q

balance between the sympathetic and parasympathetic nervous system: image

A
38
Q

What happens in a normal stress response?

A

CRH is released from the hypothalamus → Pituitary which releases ACTH → Adrenal gland which releases glucocorticoids → hypothalamus (glucocorticoids inhibit CRH release)

39
Q

What happens in a chronic stress response?

A

same flow as normal stress response, BUT excess glucocorticoid release can cause hippocampal atrophy and the disinhibition of the hypothalamus occurs. Causing greater risk of Psychiatric symptoms

40
Q

A

memory (declarative, spatial), learning

43
Q

Effect of stress on the hippocampus

A

44
Q

Effect of cortisol on memory

A

(increased memory is associated w/increased hippocampal volume)

45
Q

Findings on relationships between inflammatory markers and Major Depression

A
  • TNF-alpha: Increased HPA activity in acute depression leads to TNF-alpha activity. After remission, normal HPA activity, but increased TNF alpha.
