OCD vs Tic disorder
OCD is voluntary and goal directed; not caused by sensorimotor impulses
more prominent in what ethnic group
white
what drugs are used for OCD
SSRIs and can reduce compulsions and obsessions in up to 50-80% of patients
exposure and response prevention (what is it used for and how does it work)
OCD; exposure to anxiety stimuli without performing the compulsion so patients learn that compulsions do not relieve situations

4 required symptoms for diagnosis of PTSD
hyper vigilance, reliving past events, negative effects on thoughts and mood, avoidance
chronic arousal in PTSD (cause and examples)
changes in CNS; irritability, anger outbursts, insomnia
HPA axis
hypothalamus releases CRF –> pituitary releases ACTH –> adrenal cortex releases cortisol
acute stress disorder onset and duration
within a month after trauma occurs; lasts a month or less
multifinality and equifinality in developing PTSD
depends on biological, environmental and developmental factors
anxiety and depression increase the risks of PTSD (T or F)
T
resting cortisol is higher in those with PTSD (T/F)
F
epinephrine and norepinephrine in PTSD
heightened during traumatic event, leading to overconsolidation of memories and overactivation of the amygdala
dysfunction in hippocampus results in
emotional memories, dissociation, and arousal symptom
