Why diagnoses are exploding: from under-detection to over-correction
Dr. Suzanne O’Sullivan argues that medicine has swung from a past era of missed conditions (learning needs, mental health, chronic disease) to a new era of over-diagnosis. The core concern is not that people aren’t struggling, but that we’re too quick to convert ordinary human difficulty into medical disease labels.
- •Historical under-recognition of autism/ADHD and mental health issues
- •Concern that the pendulum has swung into over-detection and overtreatment
- •Rising prevalence statistics prompt the question: more illness vs more labeling
- •Medical labels may replace social change and practical support
- 2:01 – 3:28
What overdiagnosis actually means—and why a “correct” label can still harm
O’Sullivan clarifies that overdiagnosis is often misunderstood as ‘nothing is wrong.’ Instead, it’s about whether medicalizing a real struggle or risk helps the person—or burdens them unnecessarily, especially when the label doesn’t lead to meaningful benefit.
- •Overdiagnosis isn’t “the diagnosis is false”
- •Key test: ‘Is the diagnosis helping you?’
- •Medicalization can crowd out non-medical solutions
- •Labels can carry psychological, social, and practical costs
- 3:28 – 8:28
Case study: a rare genetic diagnosis that turned a healthy teenager into a patient
O’Sullivan describes diagnosing a mother’s rare genetic condition and testing her 15-year-old daughter, Abigail. Although the diagnosis was technically accurate, she reflects on the guilt of burdening a resilient teen with a neurodegenerative forecast years before it was clinically necessary.
- •Discovery triggered by noticing the daughter shared the mother’s gait pattern
- •Genetic confirmation of an extremely rare mutation with no clear treatment path
- •Diagnosis can shift self-perception: from healthy person to “future patient”
- •Overdiagnosis can be about timing and impact—not correctness
- 8:28 – 11:22
Diagnosis is not neutral: the nocebo effect and learning to “see blood”
Abigail later offers a powerful metaphor: kids cry when they see blood, but keep playing when they don’t. O’Sullivan uses this to explain how labels change attention, amplify symptoms, and reshape a person’s relationship with their body—even when nothing immediate can be done medically.
- •Labels draw attention to sensations that previously felt normal
- •Symptom monitoring can intensify distress and disability
- •Nocebo effects: belief and expectation can worsen experience
- •Resilience varies—clinicians can’t predict who will be harmed by labeling
- 11:22 – 19:10
Huntington’s without the gene: how fear can mimic disease
A pregnant woman, Valentina, learns her mother has Huntington’s and lives for years under the shadow of a 50/50 risk. She develops escalating symptoms she interprets as Huntington’s—until a delayed test reveals she never had the gene, illustrating the power of belief-driven symptom amplification.
- •Family diagnosis instantly changes identity and future expectations
- •Most at-risk people decline testing to preserve hope
- •Hypervigilance and anxiety can create convincing symptom patterns
- •Negative test ends spirals—even if normal clumsiness and stress remain
- 19:10 – 21:57
Words, scans, and incidental findings: when ‘degeneration’ becomes destiny
Dr. Chatterjee shares how a back-scan label affected him for years, and O’Sullivan adds an example of being told she had “arthritis” from an X-ray report. Together they highlight how medical language and incidental findings can turn normal variation into perceived pathology.
- •Many ‘abnormalities’ on scans are common in people without symptoms
- •Radiology language (“degeneration”) can be psychologically damaging
- •Incidental findings can trigger unnecessary worry and behavior change
- •Clinicians must connect test results to the lived clinical picture
- 21:57 – 24:21
What good medicine looks like: slow care, listening, and choosing tests wisely
O’Sullivan argues that good medicine isn’t reflex testing—it’s careful history, examination, follow-up, and selective investigations. They discuss ‘Choosing Wisely’ data showing doctors recognize unnecessary testing as a major problem, yet still do it frequently.
- •‘Test-for-every-symptom’ is not good medicine
- •Therapeutic power of being listened to and followed up
- •System pressures and patient expectations drive over-testing
- •Choosing Wisely: clinicians see the problem but struggle to change behavior
- 24:21 – 31:13
The missing safety net: how society pushes struggles into the medical system
They explore how individualism, reduced community structures, and limited social supports funnel people toward doctors as the default place for help. But seeking help through medicine often requires converting life problems into diagnosable conditions, reinforcing “collusion” between patient needs and medical frameworks.
- •Doctor becomes the catch-all support when other systems weaken
- •To access services, a label is often required
- •Medical training incentivizes diagnosis over context
- •Care pathways can unintentionally force medicalization
- 31:13 – 33:42
Hyper-specialization and ‘diagnosis stacking’: no one sees the whole patient
O’Sullivan critiques modern hyper-specialization, describing young people accumulating multiple diagnoses—sometimes to explain the same symptom. She argues for restoring generalist oversight to review medications, coordinate care, and reduce cascading prescriptions for side effects.
- •Specialists may treat slices of a person rather than the whole
- •Multiple labels can accumulate without improving outcomes
- •Polypharmacy cycles: meds for side effects of other meds
- •Need for hospital and primary-care generalists to integrate the story
- 33:42 – 1:07:00
Primary prevention’s hidden costs: borderline hypertension, pre-diabetes, and fear
They examine how lowered thresholds expand ‘at-risk’ populations and medicalize huge numbers of people to prevent comparatively fewer events. Examples include borderline blood pressure treatment and the broadening definition of pre-diabetes—raising concerns about anxiety, side effects, and downstream life impacts.
- •Lowering cutoffs increases diagnoses without proportional benefit
- •Preventing one event can mean medicalizing hundreds
- •Side effects and falls can outweigh theoretical future benefits
- •Pre-diabetes labeling may frighten many who never progress to diabetes
- 1:07:00 – 1:11:33
Cancer screening and over-treatment: detecting cells we can’t interpret
O’Sullivan explains how modern imaging finds abnormal cells that might never cause harm, especially in screening healthy people. Using breast and prostate examples, she stresses informed consent, ‘watchful waiting,’ and understanding that detection doesn’t always equal life-saving treatment.
- •Screening can save lives but also triggers unnecessary treatment
- •PSA screening: potential harms outweigh benefits at population level
- •Abnormal cells can be common and clinically irrelevant
- •Watchful waiting can prevent needless surgery and distress
- 1:11:33 – 1:27:06
Genetic testing and AI: powerful tools, weak interpretation, family-wide consequences
They discuss BRCA expansion beyond high-risk families, direct-to-consumer genetic testing pitfalls, and how results affect relatives who didn’t consent to the knowledge. AI may read scans well, but cannot decide whether findings explain a person’s symptoms—underscoring the irreplaceable role of clinical judgment and time.
- •Risk genes aren’t deterministic; context and family history matter
- •Direct-to-consumer tests may be incomplete or non–clinical grade
- •Testing implicates family members and changes shared identities
- •AI can detect patterns, but humans must interpret meaning and relevance
- 1:27:06 – 1:37:33
From illness identity to recovery identity: belonging, belief, and getting better
O’Sullivan and Chatterjee explore how diagnoses can become identities that ‘engulf’ a person, sometimes worsening symptoms and increasing healthcare use. Through long COVID recovery communities and Chatterjee’s fibromyalgia case, they argue that recovery often requires imagining a different future and loosening the grip of the label.
- •Illness ‘engulfment’ correlates with greater symptoms and healthcare use
- •Communities can support—or unintentionally reinforce chronicity
- •Recovery requires belief, visualization, and shifting attention
- •Compassionate care: validate suffering without locking identity to illness
- 1:37:33 – 1:43:08
Closing message: protect ‘any kind of future’ with careful, human-centered diagnosis
O’Sullivan’s central takeaway is that diagnosis should serve the person—not simply satisfy the system’s need to label. For young people especially, she urges caution so we can offer support without foreclosing possibility, and calls for medicine to prioritize time, listening, and whole-person care.
- •For some, delayed diagnosis preserves ambition and freedom
- •Hold diagnoses ‘lightly’—they may not need to define a whole life
- •Doctors should rely less on tests and more on narrative and time
- •We must keep the conversation open about the costs of medicalization
