From Coast to Coast - Addiction, Research, and Alzheimer's

San Diego, CA
Third year of residency has started off with a bang. I spent a few days in July at a research meeting in Minneapolis and another few days in DC for the REACH orientation program (Recognizing and Eliminating disparities in Addiction through Culturally informed Healthcare). In early August, I was fortunate to travel to San Diego for the Alzheimer's Association International Conference. To the right is the view from my hotel room. Isn't this unreal? 

Minneapolis

I flew to Minneapolis in early July for the Diversifying CNS Workshop, a program that is committed to retaining diverse investigators (including underrepresented minorities) in neuroscience research. It was nice not to experience the chilling winter weather that the Midwest is known for. In July, the sun was out, it was 70s, and the breeze felt amazing on my face (unlike in North Carolina where it is currently 90s and very sticky and humid). It was a refreshing time learning about the neuroscience research that the other participants (post-docs, early-stage investigators, and graduate students) are carrying out in their careers. The support and advice we offered to each other, as well as the community-building activities, were energizing. Outside of our 2-day meeting, I'm grateful for the chance to meet with a friend from high school who is currently a medical student at the University of Minnesota. We grabbed food from French Meadow, a nice, organic, cafe and bakery in Minneapolis. I am not a vegetarian, but the veggie burger from this place was the absolute bomb. On another night, I ordered takeout from Tea House, a popular Chinese restaurant nearby the Graduate Hotel. That Chinese food was also pretty bomb.

DC

After the 2-day stay in Minneapolis, I returned to NC for my afternoon Neurology clinic, then drove to DC the following morning to attend the orientation for REACH. REACH is an Addiction program that strives to build the capacity of the workforce to better care for racial and ethnic minoritized patients with substance use disorders. REACH stands for Recognizing and Eliminating Disparities in Addiction through Culturally Informed Healthcare. 

This orientation was much more broadly applicable to my career and personal life than I realized. Our discussion about the social determinants of mental health, in particular, completely transformed how I should be thinking about the broader policies and structures that contributed significantly to the inequities and disparities we are seeing in healthcare. It was incredible to hear Dr. Ruth Shim (from UC Davis, who actually gave one of the Duke Psych Grand Rounds) discuss how it is actually more important for us to consider the social determinants of health and the policies and structures that have affected our patients. 

San Diego - Alzheimer's Association International Conference

Finally, I left for San Diego very early the morning after a two-week stint on the consults service at the end of July. Highlights include the view from my hotel room (see photo above), networking, meeting people from all over the world (there were >7,000 registrants for the conference), learning about the latest research in the field of Alzheimer's, and the amazing jerk chicken I ordered from the Rock Steady Jamaican Restaurant. Am I crazy to not have known that there are Jamaicans in San Diego?! They make up a small part of the population, though. 

It was wonderful also meeting with a friend from medical school who is currently in residency at UC San Diego. We went to Oscar's Mexican Seafood, and the shrimp tacos were to die for. Ice cream at the Baked Bear also comes highly recommended.

JAR Year Part 2

I cannot believe it is already the end of my second year of residency. Where has the time gone? Stepping into my new role as a Neurology resident for the first time in July 2021 was overwhelming. Now, I can't believe I can say that I am able to go to a stroke code with a level head and clear mind, ready to help the primary team choose the next best course of action for the patient.

Below is a picture of many residents, fellows, and faculty in the Department of Neurology at Duke University Medical Center. (This is not the entire department.) It was such a privilege to stand next to these folks and celebrate our community that day (June 2022).

Duke Neurology
June 2022 

















I'd like to share a couple of patient encounters this year that have left an indelible mark on me (many did, but these stood out a bit more).

To ensure HIPAA compliance, personally identifying information has been omitted/changed and certain details of these encounters have been modified to protect the patients and their families.


What Did You Just Say?

One day in Neurology clinic, I had a follow-up appointment with a patient for tremor. He was 80 years old and from rural North Carolina (about a two-hour drive away). Let's call him Mr. S. He always brought his daughter to the visits.

"How are you doing today, Mr. S?" I greeted the patient and his daughter warmly upon entering the room. Ie made my way over to the chair with the computer and we proceeded with our visit. I was glad to hear that he was doing well on the topiramate (an anti-seizure medication that is considered second or third-line for essential tremor). Initially, he tried propranolol, but he did not tolerate it due to gastrointestinal upset. Primidone was not tried because it could interfere with another medication he was taking for long-term immunosuppression after a transplant.

Mr. S was pleasant, though oftentimes he went on tangents about random topics, such as the part-time work he was still doing in construction and his family (he always bragged about his 18 grandchildren. Yes, 18). He could also be quite interruptive whenever I spoke (but not as interruptive of our male supervising attendings, might I add), so today I tried hard to keep us on track. 

Just as we wrapped up our chat and I began to stand to do the neurological exam, Mr. S started another story, this time about his previous neurologist. He spoke with disdain about this physician, who practiced closer to Mr. S's hometown two hours away. "The propranolol he gave me helped at first, but it really made me sick," Mr. S said. I wasn't quite sure why we were rehashing something that was already established several visits ago, but I quietly listened anyway. "You know, I don't like that neurologist. He was dark-skinned, from India."

Whoa. All I could do was stare at Mr. S. A million thoughts ran through my mind:

Is he even hearing what he's saying?! And to ME, no less?

If he doesn't like this other physician who is dark-skinned, then what is he trying to say to me about me?

How is this at all relevant to the visit?

Should I just cut him off and get back to the exam?

The neurologist might not be from India, maybe he's from another South Asian country, the Middle East, or even somewhere in Europe or Africa. Why the automatic assumption that this "dark-skinned" physician with "Indian" features is from India?

The latter thought was, in the grand scheme of things, an irrelevant response to Mr. S's completely inappropriate comment. I decided to counter with, "But I'm dark-skinned, Mr. S." Then I stared at him while resting my chin in my hand to see how he would respond to that. I just wanted him to have some semblance of self-awareness about the words that were coming out of his mouth.

Mr. S stumbled a little. "No, I know you're dark-skinned. But that's different. He's a foreigner, from Iraq or India or something like that. He was born out there. You're from here." 

I noticed that the daughter was completely silent this entire time. I couldn't help but wonder what she was thinking. Was she embarrassed about her father's behavior? 

I didn't have time for this nonsense. We were getting too far off track and I needed to see my next patient. I immediately changed the subject and brought us back to the issue at hand. When he returned to the clinic months later, we carried on as if he'd never made any racist comments and revealed his true self. I shared the story with a few of my colleagues and my family. My colleagues were astonished, and my family found it humorous. "Well, you're in the South, Deb," they told me. 

When I told my mother the story, her immediate question was, "Did your patient have any mental or cognitive issues?" In fact, he did not. All of his cognitive faculties were intact, but given his overt racist ideology, I'd argue that my mother wasn't too far off to wonder if he had some issues with his mind. Racism is a reflection of moral failure, likely lack of education and enriching exposure to cultural diversity throughout one's life, and quite frankly, utter stupidity. The foundation of racism is the belief that a group of people are inferior to another simply because they have more melanin in their skin.... and look "different". That's really what it comes down to. And that is foolishness.

It is easy for us to recognize the faults in our patients who might come to us with this ideology, but it's just as important for us to recognize any biases within ourselves. I'm personally passionate about addressing health disparities among groups that have experienced socioeconomic disadvantages historically, but I'm far from perfect myself. It should be our goal as providers to practice constant self-reflection and strive to recognize any ounce of bias within ourselves that can potentially impede our interactions with our patients or the care we're providing for them.

"The only way to prevent unconscious biases from influencing our actions is to scrutinize our social behaviors, even in situations when we believe ourselves to be above discrimination." - Donald Barr, MD, PhD, Health Disparities in the U.S. (2019).


Why So Stubborn?

Earlier this spring 2022, I saw a 70-year-old male patient in the Neurology clinic at the VA Hospital with one of our well-known attendings in the Department. When asked why he presented to our clinic for the first time, his response was a shrug and a "I don't know. It should be in the records." (I can't tell you how often we hear this, especially at the VA). Review of his medical records revealed that his primary care physician was concerned about memory and walking issues. The description in the note was scarce, but it did mention that he had a heavy drinking history. There was no other contact information in the chart. No one was listed as an emergency contact. The patient, who we will call Mr. M, came to the clinic visit alone. Whenever a patient is coming in with "memory issues", he/she should always come with a loved one who can provide collateral information.

I learned that Mr. M lived alone, was not married, had no children, did not have many friends, and did not speak to his family. Unfortunately, trying to speak with Mr. M about the memory issues was like a painful climb uphill. I was not getting anywhere, and the information he provided was not helpful.

I started off open-ended. "Mr. M, tell me about these memory problems you have been having."

"My memory is fine," he shrugged.

Great start.

I thought that offering some examples might be useful. "Have you been having any difficulty remembering things like conversations from earlier in the day, tasks that you need to complete throughout the day, or perhaps words that used to come quickly to your mind when speaking with others?"

"No."

"Have your family or friends ever expressed any concern about your memory?"

"I don't have no friends. And I don't talk to my family. My sister owes me $5,000."

"Do you have a support system around here?" I asked.

"I used to have friends. They would always just call me "crazy" whenever we went out to drink. So I don't hang out with them no more."

I waited for him to offer more information but none came"What do you mean by 'crazy', Mr. M?" 

He shrugged. "I don't know, they just called me crazy."

Dear Lord. I began to feel like I was being punished. Again, I provided some options. "Did they call you crazy because of something you did? Was it the way you were dressed? Your speech? Did you drink too much? Why were they calling you crazy?"

"It wasn't because I drank too much. I don't know why."

"Can you think of anything at all, Mr. M?" I felt myself trying to control my annoyed tone. This was probably the best I was going to get for collateral information.

He paused. "Well, they thought I stumbled on my feet a lot, and that I'd say things that don't make sense."

OK maybe this was going somewhere. I decided to address the stumbling first. "Have you noticed that you've been stumbling on your feet too?"

Mr. M proceeded to describe, with more painful prompting, a picture of syncopal episodes; in his mind, however, the "blacking out" and frequent falling were due to vertigo. (Vertigo, by definition, refers to a sensation of false motion, which he did not at all describe). He refused to use a cane or any assistive walking device because it "made him feel old". (You are 70 years old, Mr. M, I wanted to say). “I just don’t have to fall backward and I’ll be good."

As for "saying things that don't make sense", he explained that months ago, his friends told him he'd forget conversations and had word-finding difficulties from time to time. Throughout all of this, he continued to dismiss his friends' concerns and adamantly state that his memory was fine. I couldn't help but wonder if a denial of the memory problems led him to cut off his friends.

He denied having any problems with his activities of daily living (bathing, dressing, toileting, eating) or instrumental activities of daily living (managing finances and medications, going grocery shopping, driving, etc). Truthfully, I didn't believe some of this because I could already tell that the information he provided wasn't very reliable. He reported drinking only 2 beers/day and 4 on the weekends (also didn't quite believe this given a significantly documented heavy drinking history). He scored a 16/30 on the Montreal Cognitive Assessment (MoCA), our most commonly used neurocognitive test in the Neurology clinic. 16/30 is a poor score, but the MoCA has cultural, language, and educational biases. His highest level of education was high school.

My attending (who has practiced neurology for over 40 years) and I spent a long time trying to convince Mr. M to speak with our Social Worker and see the cardiologists for his episodes of loss of consciousness that were consistent with syncope. He spent 20 minutes alone insisting to my attending (again, who has practiced neurology for over 40 years) that his "blackout" episodes were due to vertigo, not syncope. I grew frustrated after we spent a long time (and multiple times) trying to patiently explain the difference to him. This also wasn't the primary reason for the visit in the first place. 

While writing the note after the visit, I couldn't help but feel discouraged. My initial frustration turned into sadness. We diagnosed the patient with mild cognitive impairment and insisted that he speak with our Social Worker for resources (including an assistive device to help protect against the falls, and get plugged in to a VA support program for individuals with cognitive impairment. We felt particularly strongly about getting him connected to these resources because he had no family or friends around. I was discouraged because he was refusing help (which made me wonder why he even came to the appointment in the first place), and because there was a possibility in the near future he'd suffer another syncopal episode that could result in a massive head injury. Or continue to decline in his cognition, impairing his ability to even take care of himself and complete activities of daily living.

How do you help someone who doesn't want to be helped? This was a particularly challenging case because it hit close to home (I have had many personal experiences with struggling to help loved ones who do not wish to be helped), but I also found it galvanizing to strive to advocate for patients (especially those that have historically suffered from many social disadvantages) even when they cannot or refuse to demand for themselves the things they need to be in good health.

Neurology Junior Assistant Resident (JAR) Year Part 1

I am halfway through my second year of residency (first year of focused Neurology training), and I am both exhausted and thrilled to be doing what I love - saving people's brains (and spinal cords too, sometimes).

The learning curve as a JAR (Junior Assistant Resident) is much steeper. Not to mention the added responsibilities we are tasked with, including teaching interns and medical students, running to stroke codes, providing guidance to medical teams that have requested our expert advice on their patients, etc. 

As a PGY-2, I complete inpatient rotations such as Stroke, General Neurology, the Neurology consult service, the Neuroscience Intensive Care Unit, and outpatient rotations in neuroimmunology, headache, neurodegenerative (i.e. movement, memory disorders), and at the Durham VA Hospital. We also have a few weeks of elective time which we can use to complete rotations in certain sub-specialties and related areas such as neuro-ophthalmology, neuro-otology, sleep medicine, neuroradiology, and research. 

2021 was overall a tough year, what with the demands of residency and the stress of the persistent COVID pandemic, but truthfully, I am so grateful for the challenging experiences because they have made me into an even stronger and more mature individual. I am also grateful for my achievements this year, which would not have been possible without the mentorship of incredible faculty. This includes the Duke R38 Research Grant to study some of the mechanisms underlying racial disparities in Alzheimer's Disease. I appreciate the opportunity to share more about my research interests on the Duke website through a Resident Spotlight interview. I've grown more passionate about cognitive impairment over the last few years and decided to take up volunteering as a Community Educator through the Alzheimer's Association. 

I'm tired but these activities are fulfilling and honestly, they keep me going. Dr. Siddhartha Muckherjee's 2018 article in the NY Times entitled "For Doctors, Delving Deeper as a Way to Avoid Burnout" encapsulates how much the extracurricular pursuits we're passionate about can keep us engaged in our medical careers. Throughout the article, in discussing his and a few of his former medical school classmates' research pursuits, he states, "We survived, I think, by deepening our commitments to research. We tried to increase our mastery within peculiar medical niches. And powerful, autonomous interests kept us going." Importantly, however, the support of my family, friends, co-residents, and therapist has been critical for my mental health and overall survival in residency.

I cannot forget the sheer exhaustion I have experienced just over the past few months, especially during my time rotating through the Neurology consult service. I remember that one of my busiest nights was in early August 2021, a couple of months into my first year as a Neurology resident (PGY-2). Things got so crazy that I didn’t get the chance to eat for the entire night and I barely drank any water. (Truthfully, I could and should have taken a break but unwisely chose to power through). I only ate a raspberry cheesecake cookie from the Subway downstairs nearby our cafeteria. I’m not sure I even went to the bathroom. It was a busy night. We had about 5 stroke codes and 6 consults in 12 hours. I guess it could’ve been worse, but it was still bad.

By the way, just for reference, one consult alone takes a lot of time - it involves chart review, seeing the patient to chat with them about their illness and to do a physicial exam (or even contacting family members if the patient is not able to explain what brought them to the hospital), relaying recommendations to the primary team (main medical team that is taking care of the patient), assisting with the disposition (where the patient will end up, i.e. home, admission to the hospital, etc), and writing the consult note, which consists of documentation of the HPI (history of present illness: the patient's narrative), physical exam, and assessment and plan. All of this can take quite some time.

Regardless, when I am woken up out of sleep and have to drag myself out of the cozy, dark, and warm on-call room to see that 3AM seizure consult in the emergency room, I remind myself why I chose this career in the first place.... and all becomes right in the world once more. It's truly a privilege to see patients who are suffering from neurologic emergencies and conditions like stroke, seizure, acute demyelinating diseases in the brain or spinal cord, etc, and to be able to get them the treatment they need (i.e. thrombectomy to remove the clot that's causing the stroke, anti-seizure medication, steroids for the demyelinating diseases such as multiple sclerosis, etc).

Localization in neurology is also pretty cool (and scary, depending on how you look at it). Believe it or not, one very tiny stroke in a small part of the brain (i.e. brainstem) can cause multiple tremendously debilitating symptoms, such as eye problems, weakness, speech changes, sensory deficits, and/or other symptoms. 

Stroke is certainly the biggest neurologic issue that we deal with and are consulted for in the hospital. What's the biggest risk factor for stroke? High blood pressure. Other risk factors include high cholesterol, diabetes, obesity, obstructive sleep apnea, heart disease, tobacco use, etc. We have to get our blood pressure under control! Let's also get that cholesterol under control by modifying what we consume on a regular basis. Let's try to be more active in our day-to-day as well. And the diabetes? We need to keep that in check too. If you snore and are overweight, you might consider asking your doctor to order a sleep study for you (keep in mind though that sleep apnea can also occur in people who are not overweight). If you have sleep apnea, that needs to be treated. Stop smoking! Go to your follow-up doctor visits. Take your medications. It's simple! An estimated 80% of strokes are preventable. Can you believe that?

Anyway, I'll get off my soapbox now. I will try to post another entry sometime this spring highlighting some interesting cases.

Thanks for reading! :)
