| Fight | Aggression |
| Flight | Escape |
| Fawn | Compliant |
| Affiliate | Oxytocin is released (Attachment Hormone) |
| At Least One Month: -At least one re-experiencing symptom -One avoidance -Two arousal + reactivity -Two cognition + mood -Severe enough to impact daily life -Unrelated to medication, substance use, or illness | |
| Yound Children PTSD Diagnostic Criteria | |
| Re-Experiencing | -Flashbacks -Reoccurring dreams -Distressing thoughts -Physical signs of stress |
| Avoidance | Staying away from things, people, places, activities that are reminders of the traumatic experience -Avoiding thoughts or feelings related to the traumatic event -May lead to a change in routine |
| Arousal and Reactivity | Easily Startled -Feeling on guard, tense -Having difficulty concentrating -Having difficulty falling asleep or staying asleep -Feeling irritable and having angry or aggressive outbursts -Engaging in risky, reckless, or destructive behavior |
| Cognition and Mood | |
| Burnout | Emotional exhaustion, depersonalization, and a reduced feeling of personal accomplishment are symptoms that appear to result from general occupational stress or the wear and tear of cumulative daily stressors |
| Secondary Traumatic Stress (STS) | Symptoms resulting from indirect exposure to the traumatic experiences of others |
| Compassion Fatigue | (another term for STS symptoms [less stigmatizing], can be used interchangeably |
| Individual Risk Factors | -Young age -Inexperience -High empathy -Personal History of Trauma |
| Workplace Risk Factors | High proportion of trauma cases -Low salary -Inadequate training |
| Master control of autonomic system; Plays a role in controlling behaviors like hunger, thirst, sleep, and sexual response. Also regulates secretion of hormones. | |
| Thalamus | Serves as a relay station for almost all information that comes and goes from the cortex. Plays a role in pain sensation, attention, alertness, and memory. |
| Amygdala | Part of the limbic system. Plays a role in sensing and responding to threats. Also known as the “smoke detector” of the brain. |
| Cerebrum/Cerebral cortex | Largest part of the brain; Performs higher functions like speech, language, reasoning, problem-solving, learning, fine motor control, etc. |
| Brain stem | Performs many automatic functions, such as breathing, heart rate, body temperature, wake and sleep cycles, etc. |
| Hippocampus | Plays a major role in learning and memory formation, storage, and recall. Easily damaged by stimuli or neurological disorders (e.g. Alzheimer’s). |
| Pituitary gland | Controls other endocrine glands in the body. Secretes hormones that control response to stress (among other functions). Link between the nervous and endocrine systems. |
| Corpus callosum | A bundle of fibers that transmits messages from one hemisphere of the brain to the other. |
| Gray Matter | Consists primarily of neuronal cell bodies. Rapidly increases in volume during first 10 years, then decreases. |
| White matter | |
| Neurogenesis | The creation of neuronal cells. The brain initially makes far more neurons than it needs. |
| Branching | Neurons develop branches that increase surface area for neurons to form synapses (or connections) with other neurons. |
| Synaptogenesis | The process by which neurons form connections with each other via branches or dendrites. |
| Pruning | The process by which the brain eliminates neuronal circuits because of disuse. |
| Myelination | The process by which layers of myelin are produced along neuronal axons, acting as insulation for transmission of information between neurons. |
| Neuroplasticity | The ability of the nervous system to change its activity in response to stimuli by reorganizing its structure, function, or connections. |
