Drugs that alleviate mania tend to reduce levels of the neurotransmitter

Question

BlackTom AI · Accepted Answer

To approach this question, consider what neurotransmitter systems are most closely linked with mania and the pharmacologic effects of common mood stabilizers.
Option a: serotonin. While serotonin plays a major role in depression and anxiety, mania is not typically described as being driven by excess serotonin in the same way as dopaminergic or glutamatergic activity. Treatments targeting mania do not primarily hinge on reducing serotonin levels, so this choice is not the best explanation for mania control.
Option b: glutamate. This is the correct line of reasoning because mania has been associated with heightened glutamatergic neurotransmission in certain brain circuits. Medications and research aimed at dampening excessive glutamate signaling (for example, through NMDA receptor modulation or related pathways) can help stabilize mood and reduce manic symptoms. Therefore, reducing glutamate activity aligns with pharmacologic strategies for alleviating mania.
Option c: norepinephrine. Norepinephrine is involved in arousal and mood regulation, but mania is not classically explained by an excess of norepinephrine alone. While some antidepressants affect norepinephrine, treating mania typically focuses more on dopaminergic and glutamatergic systems than on lowering norepinephrine.
Option d: dopamine. Although dopaminergic overactivity is linked to mania, and dopamine antagonists can help manage manic symptoms, the statement says drugs that alleviate mania tend to reduce levels of the neurotransmitter, implying a primary reduction in dopamine alone. In practice, glutamatergic modulation often provides a broader stabilizing effect, and dopamine-targeted strategies do not always involve a straightforward decrease of dopamine levels across the brain. Thus, this option is less precise as a general rule for mania relief compared to the glutamate-focused explanation.
In summary, the most accurate linkage is that mania can be mitigated by approaches that dampen glutamatergic signaling, making glutamate the neurotransmitter most consistently associated with reducing manic symptoms in this context.
