Exam Two Flashcards
Three interrelated anxiety response systems
Physical: flight or flight
Cognitive: attentional shift and hyper vigilance, nervousness, difficulty concentrating
Behavioral: aggression or avoidance
Rituals and repetitive activity
Young children attempting to gain control and master of their environment
Specific phobia (prevalence)
Extreme disabling fear to object or situations that pose little to no danger
Prevalence: 2 to 4% of children
Social anxiety disorder (comorbidity)
Marked, persistent fear of being the focus of attention, or doing something humiliating
Comorbidity: selective mutism
Separation anxiety disorder (prevalence & onset)
Age inappropriate, excessive anxiety about being apart from parents or away from home
Prevalence: 10% of children (most common disorder of childhood)
Onset: earliest
Generalized anxiety disorder (prevalence & onset)
Excessive, uncontrollable anxiety and worry about numerous events and activities, occurring more days than not
Prevalence: 3 to 6% of children
Onset: late childhood or early adolescence
Post Traumatic Stress Disorder
Persistent, frightening thoughts that occur after undergoing a traumatic experience
Three core features of PTSD
Re-experiencing the event
Avoidance and numbing
Arousal
Obsessive-Compulsive disorder (prevalence)
Repeated, intrusive, irrational, and anxiety causing thoughts, accompanied by ritualized behaviors to relieve the anxiety
Prevalence: 2 to 3% of children
Anxiety disorders: biological influences
Neurotransmitters: GABA, serotonin, CRH produce a disposition to become anxious
Limbic system
Anxiety disorders: psychological influences
Intrusive parenting, excessive control, anxious parents modeling fearful behavior
Insecure early attachments
Anxiety disorders: interventions
Behavior therapy: exposure to feared stimulus
Cognitive - behavioral therapy
Euphoria
Exaggerated sense of well-being
Mania
Abnormally elevated or expansive mood
Anhedonia
Lose interest in all activities
Dysphoria

1% in children, 5% in teens
Comorbidity: MDD
Common age of onset is 11 to 12
Mood disorders: genetics and family risk
Heritability ranging from 30 to 45%
Vulnerability to negative affect
Mood disorders: neurochemistry/brain functioning
Dysregulation of neuroendocrine
Role of neurotransmitters
