Psychopharmacology of Mood Disorders
This quiz is designed to assess your knowledge of the psychopharmacology of mood disorders. It covers topics such as the neurobiology of mood disorders, the different classes of antidepressants and their mechanisms of action, and the side effects and interactions of these medications.
Questions
Which of the following is not a neurotransmitter implicated in the pathophysiology of mood disorders?
- Serotonin
- Norepinephrine
- Dopamine
- Glutamate
Which of the following is the most commonly prescribed class of antidepressants?
- Selective serotonin reuptake inhibitors (SSRIs)
- Serotonin-norepinephrine reuptake inhibitors (SNRIs)
- Tricyclic antidepressants (TCAs)
- Monoamine oxidase inhibitors (MAOIs)
What is the mechanism of action of SSRIs?
- They increase the levels of serotonin in the synaptic cleft.
- They decrease the levels of serotonin in the synaptic cleft.
- They block the reuptake of serotonin into the presynaptic neuron.
- They inhibit the metabolism of serotonin.
Which of the following is a common side effect of SSRIs?
- Nausea
- Headache
- Diarrhea
- Sexual dysfunction
Which of the following is a contraindication to the use of MAOIs?
- Hypertension
- Pheochromocytoma
- Thyroid disease
- Bipolar disorder
What is the mechanism of action of TCAs?
- They block the reuptake of serotonin and norepinephrine into the presynaptic neuron.
- They increase the levels of serotonin and norepinephrine in the synaptic cleft.
- They decrease the levels of serotonin and norepinephrine in the synaptic cleft.
- They inhibit the metabolism of serotonin and norepinephrine.
Which of the following is a common side effect of TCAs?
- Anticholinergic effects
- Cardiotoxicity
- Seizures
- Weight gain
Which of the following is a newer class of antidepressants that is effective in treating treatment-resistant depression?
- Ketamine
- Esketamine
- Lithium
- Valproate
What is the mechanism of action of ketamine?
- It blocks the NMDA receptor.
- It increases the levels of glutamate in the synaptic cleft.
- It decreases the levels of glutamate in the synaptic cleft.
- It inhibits the metabolism of glutamate.
Which of the following is a common side effect of ketamine?
- Dissociation
- Nausea
- Headache
- Seizures
Which of the following is a mood stabilizer that is used to treat bipolar disorder?
- Lithium
- Valproate
- Lamotrigine
- Carbamazepine
What is the mechanism of action of lithium?
- It inhibits the reuptake of serotonin and norepinephrine.
- It increases the levels of serotonin and norepinephrine in the synaptic cleft.
- It decreases the levels of serotonin and norepinephrine in the synaptic cleft.
- It inhibits the metabolism of serotonin and norepinephrine.
Which of the following is a common side effect of lithium?
- Nausea
- Vomiting
- Diarrhea
- Tremor
Which of the following is an anticonvulsant that is used to treat bipolar disorder?
- Valproate
- Lamotrigine
- Carbamazepine
- Phenytoin
What is the mechanism of action of valproate?
- It blocks the voltage-gated sodium channels.
- It increases the levels of GABA in the synaptic cleft.
- It decreases the levels of GABA in the synaptic cleft.
- It inhibits the metabolism of GABA.
Which of the following is a common side effect of valproate?
- Nausea
- Vomiting
- Diarrhea
- Hepatotoxicity
