Chapter 5 Stress
The diagnosis of PTSD requires that symptoms must last for at least
1 month
The DSM-5 recognizes 20 symptoms for PTSD but the 4 main areas of concern are:
1. Intrusion. 2. Avoidance. 3. Negative alterations in cognitions and mood. 4. Arousal and reactivity.

Jayden is a black male who works as a lawyer. Since childhood, he has experienced discrimination and unfair treatment because of his race. He recently found out that he has high blood pressure and early signs of cardiovascular disease despite exercising regularly and being relatively young. Building on preliminary research by Lewis and colleagues, Jayden would likely show higher levels of __________ in his liver.
C-reactive protein (CRP)
_______ can augment or enhance an immune system response or cause immunosuppression, depending on the specific type that is released.
Cytokines
_________ are small protein molecules that are an important component of the immune system,. They serve as chemical messengers and allow immune cells to communicate with each other.
Cytokines
_______ are risk factors for the development of CHD
Depression, hostility and anxiety
____ or bad stress has the potential to do the most damage
Distress
Which of the following most accurately describes how early life stressors affect the perception of stress later in life? (People who are depressed see stressors as less stressful because they do not care as much about things going on around them. Experiencing stress early in life always helps people to learn how to cope with it later. Early life stressors may make us more sensitive to stress later on, and the effects of stress can be cumulative. Genetics are not related at all to how stress is perceived._
Early life stressors may make us more sensitive to stress later on, and the effects of stress can be cumulative.

The hypothalamic-pituitary-adrenal (HPA) system, where the hypothalamus releases a hormone called corticotropin-releasing hormone (CRH). This travels through the blood and stimulates the pituitary gland. This now secretes
adrenocorticotropic hormone (ACTH)
In the SAM system, the stress response begins in the hypothalamus and stimulates the sympathetic nervous system. This causes the inner portion of the adrenal glands )adrenal medulla) to secrete adrenaline (epinephrine) and noradrenaline (norepinephrine). As this circulates through the blood this causes

coronary artery deterioration
The hypothalamic-pituitary-adrenal (HPA) system, where the hypothalamus releases a hormone called
corticotropin-releasing hormone (CRH)
The brain has receptors to detect cortisol. When these are activated, they send a feedback message that is designed to dampen the activity of the glands involved in the stress response. But if the stressor remains, the HPA axis stays active and
cortisol release continues
HPA System. Hypothalamus -> CRH -> Pituitary gland -> ACTH -> Adrenal Cortex ->
cortisol.
Prolonged stress leads to secretion of the adrenal hormone ______, which elevates blood sugar and increases metabolism. These changes help the body sustain prolonged activity but at the expense of decreased ______.

anti-inflammatory cytokines such as IL-4, IL-10, and IL-13 ________.
decrease or dampen the response that the immune system makes. Sometimes they accomplish this by blocking the synthesis of other cytokine
Knowing what to expect going into a stressful situation such as surgery has proven to ____
decrease overall stress and increase recovery time
Like stress, ______ is associated with disrupted immune function
depression
PTSD is not in the anxiety disorders section. It is in the
diagnostic category called trauma and stressor related disorders. This is because experience of major stress is central to the development.
Although depression is a greater risk factor than medical factors are in predicting mortality for patients who have already had a heart attack, many physicians fail to treat depression. This oversight has been attributed to the physician's tendency to __________.

Hans Selye stated that stress occurs
in positive and negative situations.
Chronic stress appears to impair the body's ability to respond to the signals that will terminate immune system reactivity. The result of this impairment is __________.
inflammation
Chronic stress impairs the body's ability to respond to the negative feedback signals set off by cytokines production. This results in
inflammation.
Evidence is growing that inflammation—increased levels of proinflammatory cytokines—is increased in people who are under prolonged stress. This is because long-term stress seems to ______
interfere with the body's ability to turn off cytokine production.
