All substances of abuse
Although helpful for anxiety, what drugs have abuse potential when treating anxiety?
Benzo’s
What drugs can be used to treat anxiety disorders
SSRI’s, TCA’s, MAO-I’s, SNRI’s (Antidepressants)
What are positive symptoms of schizophrenia?
Hallucinations, delusions, agitation behaviors
What are negative symptoms of schizophrenia?
Anhedonia, apathy, blunted/flat affect, poverty of thought, emptiness, a motivational
What region of the brain is responsible for mesolimbic overactivity and what type of symptoms does it produce?
positive symptoms. Dopamine goes from the VTA to Nucleus Accumbens and amygdala.
What region of the brain is responsible for mesocortical underactivity and what type of symptoms does it produce?
Prefrontal cortex. Negative symptoms. Dopamine
What is the mechanism of action of benzos
the bind to the GABA receptor and will enhance the conductance of chloride ions. This results in neurons being LESS likely to fire and thus “quiets or inhibits” the central nervous system.
What is the mechanism of action for busbar
This is a partial agonist at the serotonin-1a receptor (5HT1a). It will enhance the effects of SSRI’s and can itself help with GAD.
What is the mechanism of action for abilify
Aripiprazole is a partial agonist at the Dopamine-2 receptor. In a patient with schizophrenia, by being a partial agonist, it will increase frontal lobe dopamine activity (because the baseline dopamine is low = negative symptoms of schizophrenia). It will also decrease the dopamine activity in the midbrain (limbic) dopamine (because there the dopamine is very high in schizophrenia = positive symptoms)
What neurotransmitters are impacted by PTSD?
Serotonin, GABA, Dopamine & Norepinephrine
What neurotransmitters are impacted by OCD?
Serotonin, Dopamine,
What neurotransmitters are impacted by Social anxiety disorder?
norepinephrine, serotonin, GABA
What neurotransmitters are impacted by Panic Disorder
norepinephrine, serotonin, GABA
What were the mechanism of action for typical antipsychotics?
Dopamine D2 receptor antagonists. They were intended to block the dopamine receptor sites.
