Bipolar depression is not unipolar depression treated in a bipolar patient
Read the prompt precisely: it asks about bipolar DEPRESSION, which is a narrower question than bipolar disorder and has a much shorter list of approved treatments. Most agents called mood stabilizers earned that name in mania or in maintenance, and several are ineffective or actively unhelpful in the depressed phase. Lithium remains the reference agent and is the only one with consistent evidence for reducing suicide risk, so it belongs in the answer with its narrow therapeutic index, the level monitoring, and the renal and thyroid surveillance that go with it. Lamotrigine is the anticonvulsant with the best evidence in the depressed phase and requires slow titration because of serious rash. For FDA approval specifically in bipolar depression, the approvals sit mainly with atypical antipsychotics and combinations — quetiapine and the olanzapine-fluoxetine combination among them — so say clearly which of your named agents carry approval for depression rather than for mania or maintenance.
The special populations and the two named drugs are where marks are lost. In older adults, renal decline, drug interactions, falls and cognitive effects change the calculation: lithium requires lower doses and closer monitoring, valproate carries sedation and fall risk, and lamotrigine is often better tolerated. In children and adolescents the approved list is short and age-banded, and you should give the actual ages rather than saying that some agents are approved. Then topiramate and gabapentin: neither has an FDA indication in bipolar disorder, and the evidence does not support either as a mood stabilizer, which is the answer the question is looking for. Say what each is genuinely used for off-label in psychiatry — topiramate for antipsychotic-associated weight gain, alcohol use disorder and binge eating, with cognitive slowing, metabolic acidosis, kidney stones and glaucoma to monitor; gabapentin for anxiety and withdrawal adjunctively, with sedation, misuse potential and renal dose adjustment.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Distinguish agents approved for bipolar depression from those approved for mania or maintenance.
- 02Weigh risks and benefits of specific agents in the depressed phase.
- 03Adjust selection for geriatric and paediatric populations.
- 04State the evidence and monitoring for two commonly misattributed anticonvulsants.

Course-wide instructions that accompany this question
ADDITIONAL INSTRUCTIONS FOR THE CLASS Discussion Questions (DQ) Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words. Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source. Herzing NU 670 Unit 3 DQ 1 One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words. I encourage you to incorporate the readings from the week (as applicable) into your responses. Weekly Participation Your initial responses to the mandatory DQ do not count toward participation and are graded separately. In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies. Participation posts do not require a scholarly source/citation (unless you cite someone else’s work). Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week. APA Format and Writing Quality Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required). Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation. I highly recommend using the APA Publication Manual, 6th edition. Use of Direct Quotes I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly. As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content. It is best to paraphrase content and cite your source. LopesWrite Policy For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me. Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes. Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own? Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score. Late Policy The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies. Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances. If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect. I do not accept assignments that are two or more weeks late unless we have worked out an extension. As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading. Communication Communication is so very important. There are multiple ways to communicate with me: Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class. Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.

Lithium

Lamotrigine and the approved options
Titration and rash; which agents actually carry a depression indication.
The geriatric population
Renal decline, interactions, falls and cognition; which agents are preferred.
Children and adolescents
Approved agents with their age bands.
Topiramate and gabapentin
Actual psychiatric uses, monitoring, testing and major adverse effects.
