A nurse is explaining the role of neurotransmitters in the pathophysiology of MDD to a group of nursing students. Which neurotransmitters are mentioned in the text as being involved in regulating mood, motivation, reward, cognition, and stress response?

Acetylcholine and gamma-aminobutyric acid (GABA).

Glutamate and epinephrine.

Serotonin, dopamine, and norepinephrine.

Endorphins and oxytocin.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Acetylcholine and gamma-aminobutyric acid (GABA) are not the primary neurotransmitters involved in regulating mood, motivation, reward, cognition, and stress response. Acetylcholine plays a role in memory and muscle control, while GABA is an inhibitory neurotransmitter that helps regulate anxiety and sleep. These neurotransmitters are not as closely associated with the functions mentioned in the question.

Choice B rationale:

Glutamate is a major excitatory neurotransmitter in the central nervous system, and epinephrine (also known as adrenaline) is a hormone that prepares the body for the fight-or-flight response. While both glutamate and epinephrine play important roles in various physiological responses, they are not primarily responsible for regulating mood, motivation, reward, cognition, and stress response as mentioned in the question.

Choice C rationale:

Serotonin, dopamine, and norepinephrine are all key neurotransmitters involved in the regulation of mood, motivation, reward, cognition, and stress response. These neurotransmitters have been extensively studied in the context of mood disorders like Major Depressive Disorder (MDD). Serotonin is often associated with feelings of well-being and happiness, dopamine is linked to pleasure and reward pathways, and norepinephrine is involved in the body's stress response. Imbalances in these neurotransmitters have been implicated in the development of mood disorders.

Choice D rationale:

Endorphins and oxytocin are important neurotransmitters, but they are not as directly related to the regulation of mood, motivation, reward, cognition, and stress response as the neurotransmitters mentioned in choice C. Endorphins are known for their role in pain modulation and feelings of pleasure, while oxytocin is often referred to as the "bonding hormone" and is associated with social connections and childbirth.

Correct Answer is B

Explanation

Choice A rationale:

Pharmacological interventions involve the use of medications to treat conditions like Major Depressive Disorder (MDD). This does not involve stimulating the brain electrically or magnetically. While antidepressant medications can have an impact on neuronal activity and neuroplasticity, they are not classified as brain stimulation therapies.

Choice B rationale:

This is the correct answer. Electroconvulsive therapy (ECT) is a treatment modality that involves passing an electrical current through the brain to induce a controlled seizure. This has been found to be effective in cases of severe depression where other treatments have not worked. Other somatic therapies might include repetitive transcranial magnetic stimulation (rTMS) and vagus nerve stimulation (VNS), both of which involve modulating brain activity through electrical or magnetic means.

Choice C rationale:

Psychotherapeutic interventions involve talking therapies aimed at addressing psychological and emotional issues. These therapies do not directly involve electrical or magnetic stimulation of the brain. While they can certainly lead to changes in neuronal activity and neuroplasticity, they are not the primary modalities for brain stimulation.

Choice D rationale:

Cognitive-behavioral therapy (CBT) is a specific type of psychotherapeutic intervention that focuses on changing thought patterns and behaviors. While CBT can lead to changes in brain activity and neuroplasticity, it does not involve direct brain stimulation through electrical or magnetic means like ECT or rTMS.

A. Positive life events. B. High income. C. Lack of social support. D. Optimistic thinking.

Correct Answer is C

Explanation

Choice A rationale:

Positive life events, although beneficial, are not typically considered contributors to the development of depression. Positive events generally have a positive impact on mental health and may even serve as protective factors against depression.

Choice B rationale:

High income is not commonly recognized as a direct contributor to depression. In fact, higher income can provide access to better resources and opportunities that might contribute to better mental health outcomes.

Choice C rationale:

Lack of social support is a well-established factor contributing to the development of depression. Social support plays a crucial role in buffering against stress and providing individuals with a sense of belonging and emotional connection. A lack of strong social ties can lead to feelings of isolation and increase vulnerability to depression.

Choice D rationale:

Optimistic thinking is typically considered a protective factor against depression rather than a contributor to its development. Optimistic thinking involves a positive outlook on life and the expectation of positive outcomes, which can act as a resilience factor against depressive symptoms.
