According to the neurotropic hypothesis of major depression, nerve growth factors such as ____ are critical in the regulation
of neural plasticity, resilience, and
neurogenesis
BDNF - brain-
derived neurotrophic factor
True or False: Depression is associated with the GAIN of neurotrophic support and
effective antidepressant
therapies DECREASE neurogenesis
and synaptic connectivity.
False - Depression is associated with the LOSS of neurotrophic support and effective antidepressant
therapies INCREASE neurogenesis
and synaptic connectivity.
According to the monoamine hypothesis of depression, depression is related to a
deficiency in the amount or function of cortical and limbic ___, ___ and ___
Serotonin (5-HT)
NE
DA
True or False: According to the monoamine hypothesis of depression, all classes of antidepressants appear to
enhance the synaptic availability of 5-HT, norepinephrine, or dopamine
True
According to the monoamine hypothesis of depression, AMINE levels increase immediately with antidepressant use, but
maximum beneficial effects of most
antidepressants are not seen for many weeks
True
Fibromyalgia and chronic pain can be treated with which drug class?
A. SSRI
B. SNRI
C. MAOI
B. SNRI
Which atypical antidepressant is most effective at treating post-partum depression?
A. Buproipion
B. Mirtazapine
C. Brexanolone
D. Esketamine
C. Brexanolone
True or False: Esketamine acts on Gluaminergic system
True
MAOI’s act on ___ and ____ systems
Serotonin and NE systems
How can stress disturb HPA Axis, leading to major depressive disorder?
- Elevates cortisol
- Fails to suppress ACTH in response to dexamethasone challenge
- Chronically elevated CRH
True or False: In Major Depressive Disorder, you can have diminished thyrotropin release in response to thyrotropin-releasing-hormone
True
___ and ___ increase BDFN
Glutamine and Monamines
True or False: Elevated monoamines can lead to decrease HPA Steroid abnormalities (aka: decrease cortisol level)
True
Cortisol binding to glucocorticoids receptors in the ___ will inhibit BDNF
A. hypothalamus
B. thalamus
C. hippocampus
C. hippocampus
The response to antidepressant drug treatment generally has a “therapeutic lag” lasting ___weeks before a measurable therapeutic effect becomes evident. What is hypothesized to cause this lag?
3–4 wks
This lag is related to delayed PS changes
When depression improves, first ____ improves, then ____, then ___
sleep; mood; cognition
Why are antidepressants not good as a monotherapy for treating bipolar?
Can induce a switch from a depressed episode to a manic or hypomanic episode in some
patients
Buproprion and some tricyclic antidepressants can reduce ___ threshold
seizure
MAOI’s block MAO, preventing breakdown of…
A. DA
B. NE
C. 5-HT
B. NE/C. 5-HT
SSRI’s and SNRI’s block ___
SNRI’s block ___ and ___
Tricyclic antidepressants block ___, ____, and _____
SERT
SERT and NET
SERT, NET, and alpha-1 adrenergic receptor
___represent a chemically
diverse class of agents that
have as their primary action
the inhibition of the
serotonin transporter
SSRIs
Which class the most common
antidepressants in clinical
use?
SSRI’s
True or False: SSRI’s have high
affinity for monoamine
receptors but lack the
affinity for histamine,
acetylcholine, and α
adrenoceptors that is seen
with the tricyclic
antidepressants (TCAs)
True
True or False: SSRI’s block SERT and NET
False - just SERT; little to no effect on NET
What are the SSRI drugs
