What a Case Needs: The Life A Case Study Leaves Out

In graduate school I was handed a case. Fourteen-year-old female athlete, fainting on the field. It was inside a functional medicine and sports nutrition course, so the assignment was clear: what should she eat, and when, to stay fueled through competition and stop the fainting.

I could have done the exercise without letting my mind do what my mind does. Pre-competition meal, post-competition meal, hydration, timing, ratios. I could have written it well, turned it in, and felt fine about it.

But my brain thinks in systems. I cannot see a case without contemplating the whole. Her comprehensive history. Any other aches, pains, signs, or symptoms. And what was true about her everyday patterns and habits.

The presenting complaint—fainting—was never the answer. It was the first piece, face up, in a picture I couldn’t yet see. By the time I was reviewing this case, I’d seen something similar hundreds of times in my own clinical work. Out of range thyroid markers. Resistant weight loss. Interstitial cystitis diagnosis. Or fainting on the field during a game. I’d already learned in real time that if I targeted the concern in isolation from the person, I missed the opportunity to help them fully and sustainably. If I was lucky, they received a short-term resolution to that specific problem. But what was more likely was that another challenge would arise and they’d show up again in my inbox—initial problem settled, new one arising—or move on to another provider for that next thing.

So what I kept thinking about during that assignment was everything the one paragraph did not tell me.

Was she menstruating? If so, when had she started, and how regular was she? When did the fainting start? How often did it happen? What did her home look like on a weeknight? Who wanted her on that field—her, or someone else? What did we know about the games or practices where she didn’t faint? And I wanted to know whether anyone had asked her about the outcome she wanted, and whether she’d have answered honestly if they had.

None of that detail was available to me in the case study. It wasn’t withheld. It had been excluded from the start, because a case that included the individual could not be easily evaluated.

I regularly differentiate between acute and chronic care. If that girl goes down on the field and doesn’t get up, narrowed attention is exactly what she needs. Someone has to move fast on one variable. The apparatus of acute care exists to make that possible, and I’ve spent my career arguing that this is a form of mastery. I stand by those words. A body in crisis needs someone who can localize, focus, and act.

But the fourteen-year-old in the case study wasn’t in an immediate crisis. She was fainting and recuperating repeatedly, over a season, recovering enough to continue playing. And the case had been built to be graded, not for triage, or even assessment.

I completed the exercise. I got the mark. And the discomfort I felt doing it turned out to be at the heart of everything I’ve built and written about since. What had I learned doing the exercise for the grade? And whose accomplishment was my grade actually measuring?

A case study isn’t a life with some details left out. It’s a form with requirements. And the first requirement is that it resolve. There’s one variable in play, an outcome you can measure and mark as a victory, a success story. Which is necessary in some forms of medicine.

The questions I wanted to ask might have helped her. They would not have shown that I’d read the textbook, which was the thing being measured. They would have made the exercise time-consuming for the professor and virtually ungradeable.

Unless curiosity were graded as heavily as the cure, which is rarely the case.

The removal of the information I wanted wasn’t carelessness. The removal was the pedagogy.

Years before grad school, in July of 2000, my husband Isamu had his second craniotomy to remove tumor regrowth in his corpus callosum that was affecting his gait and balance. The first surgery had been just three months earlier.

The neurosurgical resident performed his rounds in the morning. He’d stand at the foot of the bed and talk about the closure of the skull. He’d get up close and put his fingers on Isamu’s shaved scalp—the line of black sutures running ear to ear, the swelling, and talk about how well his sewing was holding. He stood proudly as his attending told him it was beautiful work.

He wasn’t wrong. It’s not easy to stitch a head closed that’s still healing from a previous opening.

Isamu was thirty-two years old, sitting up in bed two days after the operation, the computer programming book he’d been reading open on his lap. I was in the vinyl recliner, where I had uncomfortably spent the night, draped in a scratchy cotton sheet.

They didn’t ignore Isamu completely. They asked how he was doing, and he said fine, because that was the answer the question was built for. Then they returned to the sutures, which were the part of him that most interested them—the part that could be quantified and assessed. The part that yielded the compliment for the trainee: beautiful work.

A couple of weeks later Isamu renewed his driver’s license. He went to the DMV with the stitches still in place, sat down, and looked into the camera. Swollen head, black wires across his scalp, face stoic and composed, like a mug shot. Snap.

I still have that driver’s license in a drawer, twenty-six years later. What you first see in that miniature photo is what everyone in the hospital had been looking at. Not the man with a pregnant wife, a computer programming book open on his lap, and a future he was still building toward. But the barbed wire across his crown. The man is somewhere beneath them, holding steady, waiting for the flash.

That was the beginning of a particular type of noticing for me. A person can be fully in the room and the only part of him anyone can see is the part that can be evaluated. The A1c. The out-of-range flag. The scar. The scan.

So when I was presented with a paragraph about a girl fainting on a field, I couldn’t read it as a case. I’d already watched what gets left out of the record. And I’d already decided what I wanted my own beautiful work to be—not the closure, but the person under it.

Something else came out of that assignment and followed me into every book I read in my field.

A case used for discussion earns its keep. Someone can raise a hand and ask whether the patient is hydrating or pooping, or what she was most worried about after the procedure. The case is a prompt, and the room supplies what the page left out. Conversation. Concern. Curiosity. The case I received arrived as a written assignment with a mark at the end. There was no margin to ask anything. But I understand what the model is for, and I’ve taught with it as well.

On the page of a book a case is even further removed from critical thinking. There the case arrives finished. It also can’t be questioned, and it’s already been strategically selected. It’s the punctuation to the sentence the book itself represents.

That choosing is what I’ve come to watch for. An author with a framework deemed worthy of publication has years of patients to draw from, and the ones who make it into the book are the ones who demonstrate the framework working. The woman who didn’t improve is not documented. The woman who did improve for reasons the framework can’t claim, is not in the book. You get the resolved version and never see which shelf it was pulled from.

The same thing happens in research. When a trial reports that sixty percent responded, that means that forty percent did not, and they had reasons. That work exists—subgroup analyses, responder analyses—but it’s usually secondary, often underpowered, and it rarely survives the trip to the journal, let alone to you. What travels is the headline number.

At least there’s a study underneath that number.

Emi Nietfeld went through the footnotes of The Body Keeps the Score for an article published in Mother Jones. The book states that traumatized children have fifty times the asthma rate of their peers. The footnote points to a paper on the long-term effects of incest—a paper that never mentions asthma. The study’s author, Jennie Noll, told Nietfeld her group has never published on asthma.

You have no way to audit a footnote. We read the claim, see the citation, and reasonably assume one supports the other. That assumption is what a citation is for. You’re likely not going to email an author to ask about the source of a number. And we extend the same trust to the case studies, where there isn’t even a footnote to check. The case studies ask for the same trust and offer less to verify. It took a reporter a year of pitching and months of checking to find that in places the references in that book didn’t support the claim.

Which means what we’re often holding is a theory wearing the clothes of a clinical record.

This is partly why I’ve been reading novels about old women.

Nobody in them improves in order to prove something. They just keep living, and I get to watch.

I read fiction now in a way I didn’t for most of my working life. I’m far from the beach. And I’m not looking for an escape, though sometimes it serves that purpose too. I read fiction because it’s the only place I can sit beside a whole life for three hundred pages and not be asked what I’d do about the one isolated thing that’s bothering the main character.

Doris isn’t in The Red Address Book because she demonstrates something about aging. She’s ninety-six and alone in a Stockholm flat with the address book she’s had since she was ten. Each time someone died, she crossed out the name. She’s been doing it for eighty years, and almost every name is crossed out now. The novel moves between the woman she is now and the girl who was sent out to work at thirteen, and we get to hold both—Doris today and the trajectory of Doris’s life. The history isn’t intended to explain the present. It accumulates into one continuous person.

[We’ll be reading The Red Address Book in the first ROAR Book Club later this month. Comment if you want to join.]

Lillian Boxfish Takes a Walk does it across a single New Year’s Eve in 1984. An eighty-five-year-old woman walks ten miles through Manhattan while sixty years of her own life join her en route. Mad Mabel does it differently—as we get to know eighty-one-year-old Elsie, who was Australia’s youngest convicted murderer.

I know that nothing is being smuggled in these books. I’m aware that Doris was invented. The book doesn’t borrow the authority of a clinical record while being written toward a conclusion. It isn’t claiming to be evidence of anything, which is what lets me trust what it shows me about a long life.

What all of these books give me is duration.

A case is a cross-section—one woman, one moment, the variables that fit on the page. The presenting problem given from a fixed point in time. A novel is the same woman at eighty-five and at twenty-two, and we get to hold the expanse. Her aches show up. So does everything that came before them, arriving all at once and unsorted, which is the part no intake form can produce.

I finish these novels with more empathy than any case study ever gave me, and I don’t think that’s sentiment. I think it’s information I was structurally prevented from having and that most medicine has written out of the methodology. Which may be okay for some types of practices, but was never acceptable in my own.

This is also, I’ve come to think, where the longevity conversation goes wrong.

The dominant model is the case study at scale. Isolate a variable, make the rest inert, measure the outcome. Metformin. Senolytics. mTOR inhibitors. The compound is the variable. Everything else about the person taking it is noise the design exists to suppress.

But consider what else actually has evidence behind it for extending life. Connection. Purpose. Being known by someone over a long time. These resist the design rather than fitting it. Researchers do try—there are trials of loneliness interventions, validated instruments for purpose in life, cohorts that follow people for decades. What they can’t do is hold the rest of a life static and administer belonging on a schedule. And what can’t be isolated can’t easily be sold, which is a large part of why the intervention with a molecule attached gets the headlines every time.

This is the strangest part: The factors with the best evidence behind them are the ones a novel is built to show and a study is built to exclude. Doris at ninety-six, going through a list of the people she has outlived. Every story opens into who the person was to her, when they met, what was said and what wasn’t, and what her life looked and felt like in the years she had that person in her life. That’s a document about connection and its loss across eight decades. Not a measure of it. You feel the weight of the names accumulating, because you’ve been given the years they came from. No trial could hold that still long enough to count it. Connection over a lifetime isn’t a variable. It’s the shape of the life.

I’m not against the molecule. I’m saying we’ve built an entire field on a structure that requires life to be removed and we revert to it again and again. And then we wonder why the results don’t land on actual people. Ourselves included.

Something else changed for me in this, and it took longer to see.

I’ve worked in a field that defines success as an outcome. The symptom resolved. The fainting stopped. That’s a fair definition and it’s the one the case study taught me.

What I believe now is that success looks like a person becoming legible to herself. Knowing what her own body responds to, what sets it off, what settles it, in her particular life with its particular pressures. That’s a harder thing to measure and it doesn’t produce a hook. It also travels with her, which no protocol ever does.

The meal plan would have made me legible. The top ten lists are, again, about me. They make me appear to have all the answers—to be competent, thorough, correct. But they don’t necessarily have anything to do with making that girl legible to herself, and she’d have been fourteen years old, fainting on a field, with no idea why.

So here are the two questions I’ve been carrying, and they have opposite answers.

What does a case need in order to be studied? It needs to be reducible. Fewer variables, a stable frame, a resolution.

What does a life need in order to be worth reading? It needs to be irreducible. You stay with Doris because you can’t tell which thing is causing the other, and the not-knowing is the whole reason to keep turning pages.

I can’t write the story that confirms what I already want to tell you. I can only read the ones that make me think differently, and carry what they’ve shown me about the woman in front of me who has a life the intake form has no field for.

Where else do we get to sit beside a full life, except on the page? One other place. You’re in one. Unedited, unresolved, with everything still in it—including all the parts you’ve learned to leave out when someone asks.

The Red Address Book is our first ROAR (Reading on Aging, Reframed) selection. We meet Thursday, August 27 at 4pm PT / 7pm ET.
