TOPIC 2 - anxiety and somatic disorders Flashcards
brainstem is composed of
medulla, pons, midbrain
cerebellum is responsible for
motor control and cognitive processing
the amygdala processes
fear and anxiety
hyperactive vs hypoactive amygdala
hyper - trauma, may underlie in schizophrenia
hypo - respons to antidepressants
what do antianxiety drugs do to the limbic system
slow
why do drugs that affect brain function stimulate resp depression
basal ganglia controls movement of the diaphragm that is essential for breathing and the basal ganglia is slowed with antipsychotic drugs
what part of the brain is associated with schizophrenia
thalamus and prefrontal cortex
what system is disrupted in depression, anxiety, insomnia, substance use disorder, and alzheimers
how CRH stimulates the cortex to secrete cortisol
first line drug for treating ADHD
sympathomimetics
common side effects of stimulants
decreased appetite and weight loss
CT scans
can detect lesions, abrasions, areas of infarct, aneurysm
MRI and fMRI
used to exclude neurological disorders in those presenting with mental illness
MRI and fMRI
used to exclude neurological disorders in those presenting with mental illness
can detect edema, ischemia, infection, neoplasm, trauma
detect blood flow to functionally active brain regions
PET scan
detect oxygen utilization, glucose metabolism, blood flow, and NE receptor interaction
dopamine
important neurotransmitter involved in cognition, motivation, and movement
stimulate hypothalamus to release hormones
ACH
plays a role in skeletal muscle movement, arousal, memory, and sleep-wake cycle
NE
mood, attention, arousal, stimulate fight or flight
serotonin
mood, sleep regulation, hunger, pain perception, aggression, libido, hormonal activity
histamine
alertness
inflammatory response
GI secretion
GABA
reduce anxiety, excitation, aggression
muscle relaxing
how do SSRIs work in the body
inhibit the re uptake, making it stay longer in the synapse
SSRIs are commonly used to treat …
panic disorder, GAD, OCD, PTSD, social phobia
what does buspirone do
reduce anxiety without causing immediate sedative and mildly euphoric effects of benzodiazepines
action of benzos
promote the activity of GABA
physiological response of anxiety
associated with muscle tension and vigilance in preparation for future danger with cautious or avoidant behaviors
difference between fear and anxiety
anxiety - no known cause
fear - known cause
why is normal anxiety beneficial
provides energy needed to carry out the tasks involved in striving toward goals
acute anxiety
imminent, real, or potential loss that threatens an individuals sense of security
triggered by an acute stressor
pathological anxiety
- intensity is our of proportion to the threat
- emotional response persists after the threat is resolved
- emotional response becomes generalized to benign situations
physical symptoms of mild anxiety
restless, irritable, tension relieving behaviors such as nail biting or finger tapping
physical symptoms of moderate anxiety
tension, pounding heart, increased pulse and resp, voice tremors
what do patients have a sense of with severe anxiety
impending doom
symptoms related to panic level anxiety
confusion, shouting, screaming, extreme withdrawal, hallucinations
what levels are affected with panic level anxiety
perceptual field
ability to concentrate and learn
physical manifestations
what should you do as a nurse when a patient is experiencing mild to moderate anxiety
remain calm, recognize patient distress, be willing to listen
what should you do as a nurse when a patient is experiencing severe to panic level anxiety
firm, short statements to be better understood
speak slower
wait longer for responses
repeat comments
what determines if a defense mechanism is adaptive or maladaptive
adaptive - healthy
maladaptive - unhealthy
frequency, intensity, and duration determines
healthy defenses
altruism, sublimation, humor, suppression
intermediate defenses
repression, displacement, reaction formation, somatization, undoing, rationalization
immature defenses
passive aggression, acting out behaviors, dissociation, devaluation, idealization, splitting, projection, denial
altruism
emotional conflicts and stressorts are addressed by meeting the needs of others which in turn gives them gratification
sublimation
unconsciously substituting constructive and socially acceptable activity for strong impulses that are not usually considered acceptable
ex: man with strong hostile feeling participates in contact sports
humor
emphasizing amusing or ironic aspects of the conflict
suppression
conscious denial of a disturbing situation or feeling
repression
excluding unpleasant or unwanted experiences or ideas from conscious awareness
first line of psychological defense against anxiety
displacement
transfer of emotions associated with a specific person, object, or situation to another person that is not as threatening
ex: dad yells at mom, mom yells at kid
reaction formation
unacceptable feelings are kept out of awareness by developing the opposite behavior or emotion
somatization
repressed anxiety is demonstrated in the form of physical symptoms that have no organic cause
undoing
performing an action to make up for previous behavior
rationalization
justifying illogical or unreasonable ideas, actions, or feelings by developing explanations for the behavior
ex: everybody cheats, why wouldn’t I?
passive aggression
indirectly and unassertively expressing aggression toward others
masks covert resistance, resentment, and hostility
acting out behaviors
by lashing out at others, an individual can transfer the focus from personal doubts and insecurities to another person or object
