2. The mind and body are closely intertwined.
Definition of stress:
anything that taxes one’s personal resources.
Distinguish from distress, which refers to a state of suffering.
3. Adjustment Disorders Mildest disorder
Maladaptive reactions in adapting to an identified stressor that develops within a few months of the onset of the stressor.
Impairment in social, occupational, or academic functioning exceeding normal reactions to stress.
Judgment call on boundaries between expectable reaction and an adjustment disorder.
4. Stress and Illness Psychoneuroimmunology-
The study of the relationship between stressors, endocrine, nervous, and immune systems.
The endocrine system-
ductless glands that secrete hormones
When a stressful event occurs, the hypothalamus stimulates the nearby pituitary gland to secrete ACTH. ACTH stimulates the adrenal gland(the outer layer/adrenal cortex) which releases a group of steroids, corticosteroids.
Catecholamines such as epinephrine (aka adrenaline) and norepinephrine (aka noradrenaline) are released by the adrenal medulla(the inner layer).
5. Immune system
Works through leukocytes, inflammation.
Study on dental students
Measured immunoglobulin A (an antibody that protects the body against infections). Immunoglobulin A was lower during stress school periods.
6. Studies on medical students
Also show poor immune functioning during final exam time.
Support system improves immune functioning.
7. Stress and Life changes Look at stress-illness connection by quantifying life stress in terms of life changes-research by Holmes and Rahe - “Scale of Life-Change” units.
8. Cont Stress and Life changes General Adaptation Syndrome by Hans Selye.
There is a biological response pattern to prolonged/excessive stress.
GAS includes 3 stages
9. Cont Stress and Life changes
10. Cont. Stress and life changes Stress also causes the release of corticosteroids.
On a short-term basis, corticosteroids reduce inflammation and fight allergic reactions; however, on a long-term basis, they weaken the immune system.
11. Psychological factors that moderate stress Styles of coping
Self-efficacy expectancies
Psychological hardiness
Optimism
Social support
Ethnic identity
12. Psychological factors and physical disorders.
Psychosomatic disorders
Physical disorders that are caused or exacerbated by psychological disorders.
Headaches
Tension headaches
from muscle tension
13. Most frequent
dull, steady pain
Migraine
due to changes in blood flow to brain
piercing/throbbing
Migraine without aura (common migraine); has a sudden onset.
Migraine with aura (classic migraine) is preceeded by an aura (perceptual distortions) connected to changes in serotonin/norepinephrine availability to the brain.
14. Theoretical perspectives on headaches Individual response specificity
People respond to a stressor in idiosyncratic ways
Imbalances in serotonin levels due to genetics
These imbalances lead blood vessels in the brain to contract/dilate
Factors that trigger migraines:
stress
stimuli such as bright lights
changes in barometric pressure
pollen, MSG, red wine, hunger, hormonal changes
15. Treatment of headaches Aspirin, ibuprofen, or acetaminophen, caffeine, or serotonin regulators
Thermistor (registers temperature with a sound) enables an individual to alter the blood flow to a particular area such as the hand.
Biofeedback
16. Cardiovascular Disease Risk factors
age
gender
family history
SES
obesity
hypertension
serum cholesterol - LDL(low density lipoprotein) found in animals (bad) Exercise reduces LDL. HDL sweeps out
17. Cont. Risk factors for Heart Disease Patterns of consumption:
drinking, smoking, overeating, etc.
Type A personality
Social environmental stress
Sedentary lifestyle
Ethnicity (African-American highest)
18. Asthma May be triggered by an allergic reaction.
Or a cold,
dry air
It may be an emotional response to anger, laughing.
Stress can increase frequency and severity.
19. Cont. Asthma Treatment
medication
relaxation
biofeedback
family therapy
20. Cancer Risk Factors
heredity
age
ethnicity
dietary practices
smoking
sunbathing
depression
social support/stress
21. Cont. Cancer Treatment/recovery
attitude improves recovery
social support
using coping skills such as
relaxation
guided imagery to decrease nausea/vomiting during chemotherapy
22. AIDS Focus on the psychological effects on victims, families/friends
Factors affecting progression
negative expectancy
use of denial/avoidance
sensitivity to rejection
