Hypochondriacal Neurosis: Historical Meaning and Modern Health-Anxiety Diagnoses
Author: Ukrainian Psychological Hub · Published: September 30, 2026 · Editorial Policy
Hypochondriacal neurosis is a historical psychiatric label, not a current DSM-5-TR diagnosis. In American psychiatry, it appeared as code 300.7 in DSM-II (1968) within the manual's neurosis section. The category centered on persistent preoccupation with bodily disease and fear of illness. The crucial modern point is that the old label does not translate into one single present-day diagnosis. The historical DSM-II list and its later reorganization are documented in Lake and Hurwitz's review of the neuroses, while the American Psychiatric Association identifies DSM-5-TR, published in 2022, as the current DSM edition in its DSM overview.
The modern translation also depends on which classification system is being used. DSM-5 and DSM-5-TR distribute the former territory of hypochondriasis mainly across illness anxiety disorder and somatic symptom disorder. ICD-11, by contrast, still has a formal diagnosis called Hypochondriasis (health anxiety disorder), code 6B23. The World Health Organization's ICD-11 Clinical Descriptions and Diagnostic Requirements place that diagnosis in the obsessive-compulsive and related disorders grouping, with secondary parenting in the anxiety or fear-related disorders grouping. This is one reason statements such as “hypochondriasis was simply renamed illness anxiety disorder” are too crude.
The phrase survives in historical books, old medical records, psychoanalytic writing, indexing systems, and contemporary searches. The U.S. National Library of Medicine's MeSH record for Hypochondriasis still lists “Hypochondriacal Neurosis,” “Hypochondriacal Neuroses,” and “Neurosis, Hypochondriacal” as entry terms. That vocabulary record is evidence of terminological continuity, not evidence that hypochondriacal neurosis remains a current diagnosis.
This article therefore treats hypochondriacal neurosis as a legacy term. It reconstructs what the label meant in its historical settings, follows its movement through DSM and ICD classification, and explains what a modern clinician might consider today without retroactively diagnosing a person from an old label alone. For the wider taxonomy of legacy neurosis categories, see Types of Neurosis: Historical Categories and Their Modern Equivalents.
Quick answer: what was hypochondriacal neurosis?
In its clearest formal American diagnostic use, hypochondriacal neurosis was a DSM-II category. DSM-II was published in 1968 and grouped a number of conditions under “Neuroses (300).” Hypochondriacal neurosis carried code 300.7. Historical descriptions focused on persistent concern about bodily disease, attention to physical sensations or organs, repeated fear that illness was present, and persistence of the concern despite medical reassurance. The diagnosis belonged to the conceptual world of mid-twentieth-century psychiatry; it was not a prototype checklist for DSM-5-TR illness anxiety disorder.
Even in that era, the boundaries were not as clean as the label can make them appear. A 1979 paper titled Hypochondriacal neurosis shows that the term remained active in psychiatric literature at the end of the DSM-II era. A broader historical review by F. E. Kenyon described hypochondriacal phenomena across anxiety states, depression, obsessional neurosis, hysteria, personality pathology, psychosis, organic conditions, and primary hypochondriacal states. In other words, “hypochondriacal” could describe a syndrome, a feature of another condition, or a theoretical construct depending on the author and period.
For a modern reader, the safest short translation is: an old neurosis-era label for clinically significant illness preoccupation and health-related fear. The modern diagnostic question comes afterward. It may point toward illness anxiety disorder, somatic symptom disorder, ICD-11 hypochondriasis, OCD with health-related obsessions, an anxiety disorder, a depressive presentation, a psychotic disorder with somatic delusions, a response to genuine medical illness, or another formulation. The historical label alone cannot decide among them.
Why “hypochondria” and “hypochondriacal neurosis” are not the same historical thing
Hypochondria has a much longer history than the twentieth-century category hypochondriacal neurosis. Its meanings shifted repeatedly across medicine and psychiatry. Kenyon's historical review traces this changing concept and illustrates why an older use of “hypochondria” cannot automatically be read through DSM-II or DSM-5-TR. The word could refer to bodily complaints, illness preoccupation, a syndrome occurring with other mental disorders, or a theoretical account of how psychic conflict became focused on the body.
Adding the word “neurosis” placed hypochondria inside a particular psychiatric and psychodynamic architecture. Neurosis once functioned as a broad family concept that separated certain forms of distress from psychotic disorders and often carried assumptions about conflict, defense, insight, and symptom formation. Those assumptions varied by school and decade. The broader history of the umbrella term is explained in Neurosis: What It Means Today, Symptoms, History, and Modern Diagnoses.
This distinction matters when reading old records. “Hypochondria,” “hypochondriasis,” “hypochondriacal state,” “hypochondriacal neurosis,” and “health anxiety” are historically connected expressions, but they are not interchangeable labels with a single stable definition across time.
Hypochondria in psychoanalysis: Freud's “actual neurosis” is a theory, not a current diagnosis
Psychoanalytic writing gave hypochondria another layer of meaning. Freud classified hypochondria among the “actual neuroses” in parts of his work, a theoretical category distinct from the later DSM-II diagnosis. Contemporary psychoanalytic scholarship continues to analyze that framework; for example, Bernd Nissen's paper Hypochondria as an actual neurosis explicitly begins from Freud's designation and develops a metapsychological account.
That is a psychoanalytic concept. It should be presented as Freud's and later psychoanalytic theorists' explanatory framework, not as a finding established by modern diagnostic research. Current DSM and ICD systems classify disorders descriptively and operationally. A person can therefore encounter “hypochondria” in a Freud text, “hypochondriacal neurosis” in DSM-II, “hypochondriasis” in DSM-IV, “illness anxiety disorder” in DSM-5-TR, and “hypochondriasis (health anxiety disorder)” in ICD-11 without those phrases denoting one unchanged disease entity.
This is also why historical claims about mechanisms require attribution. Psychoanalytic explanations involving libido, conflict, defense, or object relations belong to specific theoretical traditions. Modern empirical work on health anxiety investigates cognitive, behavioral, attentional, interoceptive, learning, and other mechanisms using different methods and should be evaluated on its own evidence base.
DSM-II: when hypochondriacal neurosis was a formal American diagnosis
DSM-II, published by the American Psychiatric Association in 1968, is the clearest American classification point for the exact phrase. It included hypochondriacal neurosis as 300.7 within the section on neuroses. The ten DSM-II neurosis subtypes, including 300.7, are reproduced in Lake and Hurwitz's historical review.
The historical category emphasized bodily and illness preoccupation rather than loss or distortion of a bodily function. That distinction separated it from parts of the era's hysterical-neurosis territory. The illness belief was also historically distinguished from delusional conviction. These boundaries were clinically important at the time, but the categories and explanatory assumptions around them were later reorganized.
A DSM-II diagnosis should therefore be read as a period-specific classification. If a chart from the 1960s or 1970s says “hypochondriacal neurosis,” it tells us how a clinician used the diagnostic language then. It does not establish that the same person would meet DSM-5-TR criteria for illness anxiety disorder, somatic symptom disorder, OCD, or any other modern diagnosis.
DSM-III and DSM-IV: from neurosis to hypochondriasis
DSM-III, published in 1980, transformed American psychiatric classification. The American Psychiatric Association's DSM history notes that DSM-III introduced explicit diagnostic criteria, a multiaxial system, and an approach intended to be neutral with respect to causes. The broad neurosis architecture was dismantled and its former categories were redistributed.
Hypochondriacal neurosis did not continue as a DSM-III diagnosis under that name. The relevant diagnostic territory became hypochondriasis within the somatoform-disorder framework. DSM-IV, published in 1994, continued hypochondriasis within Somatoform Disorders. This step is historically important because it shows an intermediate stage between the neurosis-era label and the current DSM system.
That intermediate stage is sometimes skipped in popular explanations, producing the misleading story that “hypochondriacal neurosis became illness anxiety disorder.” The actual trajectory is more complex: neurosis-era category → hypochondriasis within somatoform classification → DSM-5 split and reconceptualization.
DSM-5 and DSM-5-TR: the former hypochondriasis territory was split
DSM-5, published in 2013, removed hypochondriasis as a diagnosis and introduced illness anxiety disorder and somatic symptom disorder within Somatic Symptom and Related Disorders. A U.S. government comparison prepared by the Substance Abuse and Mental Health Services Administration shows the transition from DSM-IV hypochondriasis to DSM-5 illness anxiety disorder. DSM-5-TR, published in 2022, is the current DSM edition according to the American Psychiatric Association.
Illness anxiety disorder is centered on preoccupation with having or acquiring a serious illness when somatic symptoms are absent or only mild. The DSM-5 formulation also attends to high health anxiety and excessive health-related behaviors or maladaptive avoidance. Somatic symptom disorder, by contrast, requires one or more distressing somatic symptoms together with excessive symptom-related thoughts, feelings, or behaviors. A modern review of somatic symptom disorder and health anxiety emphasizes that pathological health anxiety can fall under either diagnosis depending in part on the intensity of accompanying somatic symptoms.
That division is not a simple historical rename. In a study by Bailer and colleagues, individuals previously diagnosed with DSM-IV hypochondriasis predominantly met DSM-5 criteria for somatic symptom disorder rather than illness anxiety disorder in that sample. In a separate treatment-seeking health-anxiety sample, Newby and colleagues found substantial distribution across both diagnoses. The percentages differed between studies, which is exactly why one should not use a single conversion rule for an individual person.
Those findings also show the difference between a diagnostic-history statement and an individual diagnosis. It is accurate to say that DSM-5 replaced DSM-IV hypochondriasis with new categories that divide much of its territory. It is inaccurate to infer from an old chart that a particular person “really had” illness anxiety disorder or somatic symptom disorder without a modern assessment of symptoms, duration, impairment, medical context, exclusions, and differential diagnosis.
ICD-10 took a different route: F45.2 Hypochondriacal disorder
The World Health Organization's ICD-10 preserved more explicit continuity with the old terminology. In the 1992 ICD-10 Clinical Descriptions and Diagnostic Guidelines, F45.2 was Hypochondriacal disorder within the F40–F48 block titled “Neurotic, stress-related and somatoform disorders.” The manual described persistent preoccupation with serious physical disease, frequent interpretation of ordinary sensations as abnormal or distressing, and illness-focused concern.
ICD-10 also explicitly included “hypochondriacal neurosis” under F45.2, alongside hypochondriasis and nosophobia. This is a useful reminder that the DSM and ICD did not retire neurosis language on the same timetable. A label could disappear from one system while surviving as an inclusion term or grouping language in another.
ICD-10's F45.2 also illustrates why direct translation across editions is risky. Its historical scope included body dysmorphic disorder and nondelusional dysmorphophobia, whereas current classification separates body dysmorphic disorder into a different contemporary framework. An old ICD-10 code therefore needs to be interpreted within ICD-10 itself before any modern crosswalk is attempted.
ICD-11 still uses Hypochondriasis (health anxiety disorder)
ICD-11 is especially important because it prevents an overgeneralization often made from DSM-5. In the WHO's current mental-disorders manual, the diagnosis is called Hypochondriasis (health anxiety disorder), code 6B23. The ICD-11 CDDR is the clinical manual for ICD-11, which came into effect for health reporting in January 2022.
In ICD-11, 6B23 is placed in the obsessive-compulsive and related disorders grouping and is also secondary-parented under anxiety or fear-related disorders. The WHO manual's diagnostic tables identify 6B23 Hypochondriasis (health anxiety disorder) and provide insight specifiers. This architecture reflects the classification debate around health anxiety: it has phenomenological relationships to anxiety and to repetitive checking, reassurance, avoidance, and obsessional processes.
Therefore the statement “hypochondriasis is no longer a diagnosis” is only correct if it is explicitly limited to the current DSM. It is not correct as a global claim about current psychiatric classification. DSM-5-TR does not diagnose hypochondriasis; ICD-11 does.
What phenomena were historically gathered under hypochondriacal neurosis?
Historical descriptions repeatedly converged on several themes: persistent attention to the body, fear or conviction that serious disease might be present, distress around ordinary or ambiguous bodily sensations, repeated medical consultation or requests for reassurance, and difficulty accepting reassurance for long. These themes also appear in later hypochondriasis and health-anxiety research, but their presence does not by itself establish any one modern diagnosis.
The old literature was heterogeneous. Kenyon's review described hypochondriacal symptoms in multiple psychiatric syndromes rather than treating them as a single self-contained disease in every case. That observation still has practical value: illness-focused fear can occur in different diagnostic contexts. The modern task is to determine what process organizes the presentation now.
A historical symptom description is not a screening test. It does not establish severity, duration, functional impairment, relation to medical illness, level of insight, or whether another mental disorder better explains the concern. Those are precisely the questions that modern diagnosis asks.
What does hypochondriacal neurosis map onto today?
There is no one-to-one map. The most plausible modern destinations depend on the actual presentation and the classification system being used.
Illness anxiety disorder in DSM-5-TR
Illness anxiety disorder is the closest modern DSM label for some people whose central problem is persistent preoccupation with having or acquiring serious illness while somatic symptoms are absent or mild. High health anxiety, repeated checking or care seeking, and care avoidance can be part of the presentation. Yet “closest” does not mean “identical”: DSM-5 changed both the name and the structure of the diagnostic territory.
Somatic symptom disorder in DSM-5-TR
Somatic symptom disorder may fit some former hypochondriasis presentations when distressing somatic symptoms are prominent and are accompanied by excessive symptom-related thoughts, feelings, or behaviors. The modern framework is not based on proving that symptoms are medically unexplained. A person can have a genuine medical condition and also meet criteria for somatic symptom disorder if the full psychological and functional criteria are met. The 2023 review by Scarella and colleagues summarizes this shift.
Hypochondriasis (health anxiety disorder) in ICD-11
ICD-11 provides a more direct terminological descendant: Hypochondriasis (health anxiety disorder), 6B23. Even here, the current diagnosis should not be projected backward onto a DSM-II record. ICD-11 has contemporary diagnostic requirements and its own placement within the modern classification.
OCD with health-related obsessions and compulsions
Health fears can also occur in obsessive-compulsive disorder. The organizing pattern may involve intrusive obsessional doubt, compulsive checking, reassurance seeking, mental review, internet searching, avoidance, or rituals aimed at reducing uncertainty. OCD and illness anxiety disorder can look similar at the surface level, but their diagnostic formulations and treatment planning are not interchangeable. For the modern comparison, see OCD vs Illness Anxiety Disorder: Health Fears, Checking, Reassurance, and Obsessions.
Anxiety, panic, depression, psychosis, and other conditions
Health-focused fear can occur in generalized anxiety disorder, panic disorder, depressive disorders, trauma-related conditions, and other presentations. Somatic delusions can occur in psychotic disorders and require a different assessment of conviction, reality testing, associated psychotic symptoms, and context. Body dysmorphic disorder is another distinct modern diagnosis when the central preoccupation concerns perceived defects in appearance rather than feared disease. Medical and neurological conditions must also remain part of the differential whenever symptoms warrant evaluation.
The key principle is organizational rather than lexical: modern diagnosis asks what pattern best explains the current symptoms, behaviors, impairment, time course, and context. An old word in a record is evidence about historical classification, not a substitute for that assessment.
Health anxiety is a symptom dimension, not automatically a disorder
Health anxiety describes worry, fear, vigilance, or preoccupation related to health and illness. It can range from ordinary concern to severe and disabling preoccupation. The phrase itself is not a single DSM-5-TR diagnosis. It appears in research across illness anxiety disorder, somatic symptom disorder, OCD, anxiety disorders, and medical populations.
This distinction matters especially when real illness is present. A systematic review of health anxiety and illness-related fears across chronic diseases found that illness-related fears are common in chronic medical conditions and emphasized the conceptual difficulty of deciding when fear becomes clinically excessive. A realistic concern about a diagnosed disease is not transformed into a psychiatric disorder merely because it is intense.
Clinical significance depends on the whole pattern: persistence, proportionality to actual risk and medical information, functional interference, repetitive checking or avoidance, distress, and whether another diagnosis or medical condition better explains the presentation. That judgment belongs to a proper clinical assessment rather than an online checklist.
A real medical condition and health anxiety can coexist
One of the most damaging misconceptions inherited from older language is the idea that health anxiety means “nothing is physically wrong.” Modern classification is more careful. Somatic symptom disorder can be diagnosed in the presence of a real medical condition when the required excessive thoughts, feelings, behaviors, and impairment are present. Illness anxiety disorder can also be considered when a person has a medical condition or elevated medical risk if the illness preoccupation is clearly excessive in relation to that context.
The practical consequence is straightforward: psychological formulation should never be used as a shortcut for ignoring new, changing, or medically significant symptoms. Medical evaluation and mental-health assessment answer different questions and can be needed at the same time.
Hypochondriacal neurosis vs illness anxiety disorder
These terms are historically related but not synonymous. Hypochondriacal neurosis belongs to the neurosis-era classification of DSM-II and related psychiatric language. Illness anxiety disorder is a current DSM-5-TR diagnosis with contemporary criteria. Between them lie DSM-III and DSM-IV hypochondriasis, major changes in the organization of mental disorders, and a DSM-5 split that directed some former hypochondriasis presentations toward somatic symptom disorder.
For historical writing, the distinction should be preserved even when a simplified explanation would be easier. Saying “hypochondriacal neurosis is now called illness anxiety disorder” erases both the somatic symptom disorder branch and the differing ICD-11 solution.
Hypochondriacal neurosis vs somatic symptom disorder
The older diagnosis centered heavily on illness preoccupation and bodily disease fears. Modern somatic symptom disorder is defined around distressing somatic symptoms plus excessive thoughts, feelings, or behaviors related to those symptoms. It does not require that the symptoms be medically unexplained. Some people who would once have received hypochondriasis diagnoses fall into this modern category, but others do not.
The split is empirically imperfect. Bailer and colleagues found that many people with DSM-IV hypochondriasis met somatic symptom disorder criteria, while Newby and colleagues found substantial representation in both somatic symptom disorder and illness anxiety disorder. Those studies support cautious crosswalking rather than a universal replacement formula.
Hypochondriacal neurosis vs OCD
The overlap is usually behavioral: both presentations can involve checking the body, seeking reassurance, researching symptoms, avoiding health information, or repeatedly consulting professionals. The meaning and structure of those behaviors matter. In OCD, they may function as compulsions linked to intrusive obsessions and intolerance of uncertainty; in illness anxiety disorder, the central organizing concern is illness preoccupation and health anxiety. Co-occurrence is also possible.
Because this article owns the historical hypochondriacal-neurosis intent rather than the modern OCD differential, the full contemporary comparison belongs to the English OCD cluster: OCD vs Illness Anxiety Disorder.
What the historical term does not tell you
It does not tell you that a person's physical symptoms were imaginary. It does not establish that a medical disease was absent. It does not prove that the person had illness anxiety disorder, somatic symptom disorder, OCD, or a personality disorder by current criteria. It does not establish a modern mechanism. And it does not mean that “neurotic” is an appropriate personality description.
The label also does not tell you how severe the condition was. Historical diagnoses were shaped by the concepts, manuals, and clinical conventions available at the time. Two people given the same old diagnosis could have presentations that would be classified differently today.
How to interpret “hypochondriacal neurosis” in an old medical record
First, identify the date. A 1969 American psychiatric record, a 1985 record, and an ICD-10-era European record may use similar words under different classification systems.
Second, identify the source system if possible. In DSM-II, hypochondriacal neurosis was an official category. In DSM-III and DSM-IV, the DSM diagnosis was hypochondriasis rather than hypochondriacal neurosis. In ICD-10, hypochondriacal neurosis survived as an inclusion term under F45.2 Hypochondriacal disorder.
Third, read the accompanying clinical description. Look for what the clinician actually documented: illness preoccupation, bodily symptoms, reassurance seeking, functional impairment, depression, panic, obsessional symptoms, delusional conviction, medical findings, and treatment context. The narrative often tells more than the legacy label.
Fourth, avoid retrospective certainty. A historical record can be translated into a set of modern diagnostic possibilities, but a current diagnosis requires current evidence. If the question is scholarly or archival, preserve the original term and explain its period-specific meaning. If the question is clinical, use the old label as background rather than as a current diagnosis.
Does repeated reassurance distinguish the condition?
Persistence despite reassurance was prominent in older hypochondriasis formulations, and repeated reassurance seeking remains clinically relevant in modern health-anxiety presentations. But reassurance response is not a stand-alone diagnostic test. People can seek reassurance in OCD, panic disorder, generalized anxiety, chronic medical illness, and ordinary periods of uncertainty.
Modern assessment asks what happens around the reassurance: what fear triggers it, whether relief is brief, whether checking or avoidance escalates, how much time the cycle consumes, and how it affects functioning. Those patterns are more informative than counting doctor visits or internet searches in isolation.
Treatment implications: treat the current presentation, not the old label
There is no modern evidence-based treatment protocol for “hypochondriacal neurosis” as a DSM-II diagnosis because that category is historical. Treatment today is selected according to the current presentation and current diagnosis, while medical evaluation is pursued when clinically indicated.
For clinically significant health anxiety, cognitive behavioral therapy has a substantial evidence base. A 2019 systematic review and meta-analysis of randomized trials found a moderate-to-large pooled effect of CBT on health anxiety, with benefits generally maintained over follow-up. A newer 2026 systematic review and network meta-analysis found significant effects for several psychological approaches and concluded that CBT and third-wave CBT are reasonable first-line psychological choices for health anxiety.
That evidence should not be generalized mechanically across diagnoses. OCD has its own evidence-based treatment framework, psychotic disorders require a different approach, and distress associated with genuine medical disease may need integrated medical and psychological care. The historical label is therefore a starting point for translation, not a treatment target.
Common misconceptions
“Hypochondriacal neurosis is the old name for illness anxiety disorder.”
Partly, but too simple. Illness anxiety disorder inherits some of the old territory, while somatic symptom disorder inherits another part. ICD-11 also retains a current diagnosis called Hypochondriasis (health anxiety disorder).
“Hypochondriasis no longer exists in any modern diagnostic system.”
Incorrect. It is absent as a diagnosis from DSM-5-TR, but ICD-11 includes Hypochondriasis (health anxiety disorder), 6B23.
“If someone has health anxiety, their physical symptoms are not real.”
Incorrect. Modern somatic symptom classification does not require symptoms to be medically unexplained, and health anxiety can coexist with diagnosed medical illness.
“Health anxiety is always a psychiatric disorder.”
Incorrect. Concern about health exists on a continuum and can be proportionate to medical circumstances. A clinical disorder requires a broader pattern of persistence, distress or impairment, and diagnostic fit.
“A historical diagnosis can be converted by changing the label.”
Incorrect. Diagnostic systems changed their criteria, boundaries, theoretical assumptions, and groupings. Historical crosswalks are probabilistic and contextual, not simple word substitutions.
Practical interpretation for a modern reader
If you encounter “hypochondriacal neurosis” in a book, archive, family record, or old clinical note, read it first as a historical classification marker. Ask which manual or theory was operating at that time. Then separate the documented phenomena from the label: illness fear, somatic symptoms, checking, reassurance seeking, avoidance, depression, panic, obsessional doubt, delusional conviction, or another pattern.
If those concerns are current and causing substantial distress or impairment, the useful question is not “Do I have hypochondriacal neurosis?” The useful question is which current formulation best describes the presentation and whether medical, psychiatric, psychological, or combined assessment is appropriate. DSM-5-TR and ICD-11 answer that question differently in some respects, so the classification system should always be named.
The historical term still matters because it shows how psychiatry reorganized a large area of illness-focused distress. Its value today is explanatory and genealogical: it helps us understand where current concepts came from, why their boundaries differ, and why a modern diagnosis cannot be read directly out of an old name.
FAQ
Is hypochondriacal neurosis still a diagnosis?
Not in DSM-5-TR. Hypochondriacal neurosis was a historical diagnosis in DSM-II. ICD-10 later used “hypochondriacal neurosis” as an inclusion term under F45.2 Hypochondriacal disorder. ICD-11 now uses Hypochondriasis (health anxiety disorder), code 6B23, rather than a neurosis diagnosis.
What is the modern name for hypochondriacal neurosis?
There is no single universal modern name. In DSM-5-TR, relevant presentations may be classified as illness anxiety disorder or somatic symptom disorder, among other possibilities. In ICD-11, Hypochondriasis (health anxiety disorder) is a current diagnosis.
Is hypochondriacal neurosis the same as illness anxiety disorder?
No. They are historically related, but hypochondriacal neurosis was a neurosis-era category and illness anxiety disorder is a modern DSM diagnosis with different criteria and boundaries.
Is hypochondriacal neurosis the same as somatic symptom disorder?
No. Some historical hypochondriasis presentations may map to somatic symptom disorder, especially when prominent somatic symptoms and excessive symptom-related responses are central, but the categories are not identical.
Is hypochondriacal neurosis the same as OCD?
No. Health-related obsessions and compulsions can resemble illness anxiety, and the conditions can overlap or co-occur, but OCD has its own diagnostic structure. The pattern and function of obsessions, compulsions, checking, reassurance seeking, and avoidance matter.
Does ICD-11 still diagnose hypochondriasis?
Yes. ICD-11 includes Hypochondriasis (health anxiety disorder), code 6B23, within obsessive-compulsive and related disorders and secondary-parented under anxiety or fear-related disorders.
What did DSM-II mean by hypochondriacal neurosis?
DSM-II used the term for a neurosis characterized by persistent illness and bodily preoccupation in which fears of disease were not treated as delusional psychosis. It was code 300.7 within the 1968 neurosis section.
Can health anxiety occur when someone really has a medical illness?
Yes. Health-related fear can occur alongside real medical disease. Modern assessment considers whether concern and behavior are proportionate to the medical context and whether a psychiatric diagnosis is otherwise supported; it does not assume that physical illness is absent.
Should an old diagnosis be changed to a modern one in a historical record?
For historical accuracy, preserve the original diagnosis and identify the classification system and date. A modern crosswalk can be added as interpretation, but it should be presented as a set of possible correspondences rather than a retrospective diagnosis.
