Dr Grouse: This is Dr Katie Grouse. Today I'm interviewing Dr Sara LaHue about her article, Neurologic Complications of Pregnancy and Menopause, which appears in the February 2026 Continuum issue on Neurology of Systemic Disease. Welcome to the podcast and please tell us more about yourself.

Dr LaHue: Well, thanks so much for having me. I'm really excited to talk about this topic. So, I'm Sara LaHue. I'm a neurologist at UCSF, assistant professor of neurology, and a neurohospitalist. So much of my role is taking care of people who are coming into the hospital with urgent and emergent neurologic conditions. And so that's very much a framing that I come to this chapter with.

Dr Grouse: I just want to start by congratulating you on your article, which is such a phenomenal compendium of important neurologic issues related to pregnancy and menopause, which I think I really needed and a lot of us really need and was missing, I think, in all of the literature out there. This article will be such an important clinical resource. I know for me, and I'm sure for many of our listeners, this may be a difficult question to answer because of how comprehensive the article is. But what do you hope will be the main takeaway for those who read your article?

Dr LaHue: So, I really hope that listeners walk away with understanding that pregnancy and menopause are not contraindications to providing excellent neurologic care. I think too often we default to withholding treatment, pseudo-assumed risk, rather than actual evidence of harm. And so, I think that the key message here is that protecting maternal health is protecting fetal health, and that under-treating neurologic conditions during pregnancy can harm both mother and baby.

Dr Grouse: You did say specifically in your article that I thought it was so important that presumption of harm from medications during pregnancy, due to lack of evidence rather than evidence of harm, was something that we really had to be aware of, of that bias. And how do you recommend neurologists listening to this podcast approach situations where diagnostic or management strategies become less certain due to safety considerations in pregnancy?

Dr LaHue: Yeah, that's such an important question. I really frame it as a risk-benefit calculation with a patient, and I'm very transparent about what we know and what we don't know. And I emphasize that untreated disease may also impact fetal health. I use resources like LactMed and pregnancy registries that can help provide some of the more latest data. And then when evidence is limited, I document our discussion thoroughly, and I'll often involve maternal-fetal medicine colleagues for their multidisciplinary input. So, the goal is really to have an informed, shared decision-making process rather than a reflexive avoidance of all treatments.

Dr Grouse: I think that's really important to reiterate, and I think something that we're all I think working on as we try to manage these difficult situations and conditions. Now, I want to switch gears a little bit and ask. Your article was so comprehensive and so helpful, but what isn't in the article that you wanted to put in?

Dr LaHue: There was a fair amount that I ended up having to take out. So, this is a question that's near and dear to my heart. So, I would have liked to include more on the neurodevelopmental outcomes for children who are exposed to various neurologic medications in utero. And I also wanted to discuss more about transgender and non-binary individuals who are experiencing pregnancy and menopause, as they're often underrepresented in research. They've faced unique challenges accessing care.

Dr Grouse: Now, I was really struck by one statistic in your article, specifically that intimate partner violence is a leading cause of head injury during pregnancy, and that actually homicide is a leading cause of death during pregnancy in the postpartum period in the US, which was absolutely a surprising statistic to me. What does this mean for our listeners caring for pregnant patients with concussions and head injuries? What should we be doing differently?

Dr LaHue: This is also something that really struck me when I first encountered it. I think that the statistics should really fundamentally change how we approach head injuries in pregnant patients. I think we need to screen everyone routinely and privately for violence in the home and in the relationships, and to document injuries very carefully. But we also need to be prepared if someone does screen positive. And so, it's important to be familiar with what's available in terms of resources within your community, where you work, and also to remember that that strangulation in particular is something that can cause dissection and stroke. And so, to maintain a high index of suspicion for any kind of vascular injury in these cases. So not just thinking about head injury itself, but also thinking about complications of strangulation as well.

Dr Grouse: Really a great reminder of the role that we can play in our own careers and our own clinical settings when we see cases like this. So, I really appreciate that this point was made, and I hope this will change people's practice. Now switching gears to stroke in pregnancy. Could you walk us through your evaluation and management of a patient who comes in with acute stroke in the peripartum period?

Dr LaHue: This is such an important topic, and I think the first thing I'd like to emphasize is that time is brain. Whether or not you're pregnant. It's important to get whatever imaging modality is going to be fastest. Get the CT or get the MRI as soon as you can. Don't delay for fetal concerns. The radiation risk is minimal compared to missing a treatable, disabling stroke. In terms of treatment, thrombolysis and mechanical thrombectomy should be considered just as in a non-pregnant person, when the benefits outweigh the risks. And so, I think the key is involving obstetrics early for shared decision making, and being very transparent with what treatment options are available for the individual, and to not let pregnancy alone stop you from offering standard stroke therapies.

Dr Grouse: Definitely a helpful resource, and I think the resources that you put in specifically around the considerations and differentials in these various populations. Postpartum, while still pregnant during the period of period, I think is all just so helpful and a great review. So, I encourage our listeners to check that out. Now switching over to the topic of menopause. I have to say, I really appreciated your coverage of neurologic issues related to the perimenopause period. What do you think is the biggest debate or controversy in this area?

Dr LaHue: I think this has to be our understanding of the use of menopausal hormone therapy. The pendulum, when using menopausal hormone therapy, has really swung dramatically. So, we went from routine use to predominantly avoidance. After the Women's Health Initiative was published in 2002, and now we're finding that we're starting to come more to a middle ground. I think there's still great debate when it comes around timing of initiation, formulation of the different therapies, a route of administration and also the dosing, as well as just including how to individualize therapy for individuals with neurologic conditions.

Dr Grouse: Well, going into that a little further, I know I get a lot of questions about the use of hormone therapy as it relates to stroke risk and particularly in higher risk patients such as patients who've had prior strokes, dissections, a history of migraine with aura. And I find it hard to get the answers in the literature that's out there. How are you counseling these patients?

Dr LaHue: So, I think this is where discussions around the route of administration and dosing become especially important. And this is where there's emerging literature that I think is helping to guide some of these discussions. So, for higher risk patients, I discuss how low dose transdermal formulations which can bypass hepatic metabolism and reduce clotting risk. These are medications that can appear safer in those higher risk individuals. I think the key is really individualizing the risk-benefit discussion with the patient. For a woman with severe vasomotor symptoms that are affecting sleep and cognition, who had a remote stroke. I think this is a person for whom low dose transdermal patch might be a reasonable option. All of these factors end up being considerations for that shared decision-making.

Dr Grouse: Now your article covers another topic that I often get questions about, and that's specifically regarding safety of vaginal delivery for patients with neurologic conditions that are sensitive to increased intracranial pressure. Could you summarize your advice for these types of questions when they come up?

Dr LaHue: So broadly speaking, most neurologic conditions don't require C-section delivery. And this is a procedure that, just globally speaking, as has been increasing dramatically. And so, I think that's the key message that really, most neurologic conditions don't require a C-section as a main indication. And really, the indication should be based on obstetric considerations. For most conditions, like controlled idiopathic intracranial hypertension, a vaginal delivery is fine. But for patients with mass effect or obstruction at the foramen magnum, a C-section with general anesthesia, it's probably going to be safer. The transient increase in intracerebral pressure that can come with pushing. It hasn't really been shown to harm patients who have stable, treated neurologic conditions.

Dr Grouse: I really appreciated the advice that you given in the article, which was that if generally you feel like this would be a patient who would be safe to get a lumbar puncture, you have a little less concern about vaginal delivery versus those that you feel would not be safe to get a lumbar puncture, that you'd be more leaning towards a C-section.

Dr LaHue: Yeah, that's exactly right.

Dr Grouse: Now, why do you think we have so many gaps in our understanding of how pregnancy and menopause affect neurologic conditions?

Dr LaHue: So, I think it really comes down to a perfect storm of factors. So, in 1977, the USFDA came down with the recommendation, stating that it was best to exclude all women of reproductive potential from both phase one and phase two studies. And this recommendation wasn't reversed until 1993. And there are also concerns around liability and also the fact that pregnancy is a temporary state is something that may falsely minimize the potential for delays. The potential for harms that come with delays in treatment. And I think that the fact of menopause is also historically been dismissed, despite this is something that is affecting half of the population. I think we need systemic change. We need to mandate inclusion in research. We need funding for dedicated studies. We also need to recognize women's health as a core competency and not just a special interest.

Dr Grouse: That all sounds like a great roadmap for improving our knowledge. And I really hope we get there. But hearing you talk about it really does give me hope that we can improve how we are understanding and treating these conditions. Now, your article included a really helpful overview of headaches in pregnancy, and that's certainly something I think many of our listeners are very familiar with. We do have a lot of questions around that, and I think there's a lot of areas where we don't really always know what the best thing to do is. I think that your article really gave a lot of great information and a really great framework to think about. It would be wonderful to hear you walk through your approach to evaluation of a patient who was pregnant with a new onset headache.

Dr LaHue: You'll see in this chapter that I introduce a mnemonic that's spelled out pericardium as a framework for thinking about headache and pregnancy. And here are the you specifically points to an unusual headache, referring to a new or atypical presentation of headache for the patient. I think this is an important place to start, because one of the initial considerations should be this is a new headache, or is this an old headache? If this is a patient who already has a preexisting diagnosis of migraine or some other primary headache disorder, then it's certainly possible that the headache that they're experiencing during pregnancy is also a continuation of their primary headache disorder. But certainly, our role is to make sure that we're not missing a scary complication, a secondary headache that could be dangerous to the patient. And so, then this is where I also think about, well, where are they in the course of their pregnancy. Is this person currently pregnant or are we in the postpartum period? When someone is after 20 weeks gestation, one of the first things to consider is going to be preeclampsia. And so, it's important in those individuals to check blood pressure, check urine to rule out preeclampsia, as this is always going to be top of mind after 20 weeks.

I think it's also important to emphasize that preeclampsia is not just a condition that can occur when someone is pregnant. This is also something that can occur postpartum. One needs to be vigilant for looking out for this complication during both time periods. And then I think for new headaches, I really want to focus on what the timing is and any other red flags. For example, if it's a thunderclap headache and onset, then I might be worried about something like RCBS or cerebral venous sinus thrombosis. If the headache itself is orthostatic and patient may have had an epidural, then I might think about a post-dural puncture headache, which is a, unfortunately very common complication and reason for headache in the postpartum period. I think the key is that most dangerous headaches often will occur late in the third trimester or early postpartum. And I think it's also important to remember that if you need imaging to make the diagnosis, and you should get it. The risks of missing something serious far outweigh concerns that one might have around imaging. And when possible, it's certainly preferred to get an MRI if that's available.

Dr Grouse: I really did appreciate articles, overview of the various imaging modalities out there and the overview of risk versus benefits and times where they may or may not be needed. So, yet another very useful piece of information that I think that our listeners will appreciate in your article. Now, I'm curious how did you get interested in this area of neurology?

Dr LaHue: So, it really was my interest in both reproductive health and neurology that led me to go to medical school in the first place. I knew early on at the beginning of medical school that I was interested in neurology, but I also was very drawn to obstetrics, and I recognized in medical school and then further on as, as a resident, just how vast the knowledge gaps were. When I was counseling my own patients and I found this to be just a very frequent source of frustration as both a clinician and a researcher, I very much feel an obligation to try to help fill these gaps. And I've also just been very encouraged by an outstanding community of other neurologists that I've been able to meet in this space. It's been a just a wonderful collaborative network that we've been able to grow, both within United States and even more globally, when it comes to other neurologists who are interested in this topic. And I'm just very excited to see the direction that this field is going in.

Dr Grouse: Well, we can't wait to learn more as this field develops and more is understood about the right way to approach these types of diagnostics and treatments. So, thank you for all your work in this space. And it's been absolutely fascinating reading your article and talking with you today.

Dr LaHue: Well, thank you so much for having me, and I'm just so thrilled that these important topics are going to be part of this issue of Continuum.
