Impulse Control Disorders-Zuchowski Flashcards
What are the 5 Impulse Control Disorders?
- Intermittent Explosive Disorder
- Kleptomania
- Pyromania
mpulses such as hunger originate in the (blank)
This impulse can be put off, but its drive will increase with time.
satiety center of the hypothalamus
Impulses to fear and reactions to anger occur in the (blank). If you see anger being physically manifested how does this affect your amygdala?
amygdala
even more so!! (i.e seeing an angry face doesnt light up your amygdala as much as seeing an angry person grabbing someone)
The (blank) structure such as the hypothalamus is the main region where impulses arise. These impulses are then modulated by specific areas of the (blank, blank and blank) typically resulting in (blank).
mid brain structure
cortex; the prefrontal cortex and the orbital frontal cortex
processing and suppression
The mid brain structure such as the hypothalamus is the main region where impulses arise. These impulses are then modulated by specific areas of the cortex; the prefrontal cortex and the orbital frontal cortex. When it gets here, what happens to the impulse?
information is sent for cognitive appraisal where the impulse can either be stopped or driven.
Sensory processing can be affected by many factors such as ….?
sensory deficits or distortions, cultural/social factors and level of cognition or cognitive impairment.
(blank) function in the suppression and regulation of impulse (acts as the breaks)
The Orbital Frontal (and anterior cingulate gyrus)
The (blank and blank) are the “bottom up” signals and work to drive the impulse.
amygdala and insula
What are brain disorders with secondary impulse control problems?
a. Trauma to the frontal lobes
b. Presence of epidural hematomas
c. Dementia’s, particularly Frontal Temporal Dementia
d. Vascular dementia can also show signs of impulse control dysregulation depending on what areas are affected.
T or F
Levels of neuromodulators effect impulse control
T
Low (blank) and enhanced (blank) are associated with poor impulse control and aggressive behavior.
serotonin dopamine (and norepinephrine)
Low serotonin and enhanced dopamine (and norepinephrine) are associated with poor impulse control and aggressive behaviors. These neuromodulators have their effects primarily on the (blank) brain circuitry and abnormal levels of these neuromodulators are associated with conditions such as (blank……)
cortical
- cortical lesion (trauma, tumor),
- decreased cortical volume
- orbitalfrontal/cingulate cortex processing inefficiency
(blank) GABA, (blank) glutamate and (blank) acetylcholine are also associated with poor impulse control
These neurotransmitters have their effects primarily on the (blank) and can cause what?
Reduced
enhanced
enhanced
limbic system
- hyperactivity of the amygdala and limbic system
- reduced amaygdalar volume
- emotional hypersensitivity
- kindling
Low CSF serotonin levels are correlated with what?
- more violent forms of aggression
- loss of impulse control
- greater risk taking
- more physical wounds
(blank) is associated with low social rank, and higher dysfunctional aggression
Low serotonin
“appropriate” aggression used to maintain social dominance was not associated with (blank) in monkeys
low serotonin levels
What is reactive aggression?
What happens if you have poor impulse control?
What is an example of this?
response to a perceived threat or provocation
-lower threshold to perceive provocation and/or lower threshold to repond aggressively
PTSD
What is proactive aggression?
Is it associated with poor impulse control?
a behavior that anticipates reward such as attention, esteem of peers, money and drugs and is associated with a thought process that aggression will result with a “positive outcome” i.e bullying
It is not associated with impulse control.
If you commit a murder in the context of a sex crime, what are your serotonin levels like?
What about a murderer without a sex crime?
What about for people who commit suicide?
Very low serotonin
Normal serotonin
Low serotonin
What are serotonin levels like in patients with intermittent explosive disorder?
less serotonergic innervation in the anterior cingulate cortex AND pnts have fewer platelet serotonin binding sites
What do physiological disorders do you use dopamine agonists for and what are some dopamine agonists?
Parkinsons and restless leg syndrome
Ropinirole (requip) and Pramipexole (mirapex)
Research has shown that certain impulse control problems can result from the use of dopamine agonists, what are these?
How did we figure this out?
- hypersexuality
- hyperphagia
- pathological gambling
- compulsive shopping
We compared parkinsons patients behavior on dopamine agonists with parkinsons patients not on dopamine.
(PD itself does not appear to increase risk of impulse control problems)
Using the “gas” and “brake” analogy for impulse control, which statement is most accurate?
A) Dopamine is the brake, serotonin the gas
B) GABA is the gas, serotonin the brake
C) Dopamine is the gas, glutamate is the brake
D) Dopamine is the gas, serotonin the brake
D) Dopamine is the gas, serotonin the brake
What is this:
-Recurrent verbal or physical aggression
(grossly out of proportion to provocation)
-Not premeditated
-No tangible objective
-Intermittency leads to potential for escalating meds doses and/or irrational polypharmacy
-Patients frequently report memory lapse or a “graying out” during outburst
Intermittent Explosive Disorder
