2 Main Types of Stress

Acute Stress: Survive and thrive

Chronic Stress: Can lead to dysfunction/disease

Excess Chronic Stress can result in Burnout

Immune system:altered

Hypothalamopituitary adrenal (HPA) axis

Cortisol

1. CRH injected into brain ventricles increases locomotor activity

2. CRH facilitates the acoustic startle response

3. CRH produces increased responsiveness to “stress” in an open field test

4. CRH has an “anxiogenic-like” effect in the operant conflict test

5. CRH produces enhanced suppression of responding in conditioned emotional response test

6. CRH produces a dose-dependent facilitation of stress-induced fighting

7. CRH produces “anxiogenic-like” response in the plus maze

8. CRH produces a dose-dependent taste aversion and place aversion

Behavioral (Neurotransmitter) Effects of Corticotropin-Releasing Hormone (CRH)

Physiology of the Stress Response

Importance of the return to baseline…..if not, then:

Sustained high cortisol damages/destroys the neurons mediating cortisol negative feedback restraint on CRH

Chronic stress impairs memory, learning due to damage to hippocampal neurons with hippocampal volume reduction

Excess cortisol causes many metabolic substrate derangements (hyperglycemia, proteolysis, fat deposition)

The most commonly studied interventions have involved mindfulness, stress

management, and small group discussions, and the results suggest that these strategies

can be effective approaches to reduce burnout domain scores.

Mind-Body Medicine: Therapies Meditation

Imagery

Biofeedback

Autogenic Training (self-hypnosis)

Breathing Techniques

Exercise

Yoga, Tai Chi

Efficacy of Mind-Body Therapies Cons iderable Evidence

Coronary Artery Disease (cardiac rehabilitation) Headaches Insomnia Incontinence Chronic low back pain Disease and treatment-related symptoms of cancer Improving post-surgical outcomes

Benefits of Biofeedback Increased awareness and confidence in relaxation skills

Control over “involuntary” functions

Examples: recurrent migraine headache treatment of Raynaud’s disease urinary incontinence arthritis

Let’s try an Experiment Using your Mind-Body Physiology to Manage

Stress and Improve Resiliency:

Autogenic Biofeedback with aSimple Monitor

Neural Connections:Cognitive-Emotional-Autonomic

Hypothalamus/CRH=Master StressHormone

Mind-Body Medicine practices reduce stresssignaling to the hypothalamus and decrease CRH,lower stress hormone levels & reduce sympathetic activity.Result: Vasodilation, more blood flow to skin, increased warming.
