Neurosis vs Neurasthenia: Historical Terms, Symptoms, and Modern Classification
Author: Ukrainian Psychological Hub · Published: September 30, 2026 · Editorial Policy
Neurosis and neurasthenia are related historical terms, but they are not synonyms. Neurosis became a broad and repeatedly changing category for disorders or forms of distress understood in different eras through ideas about the nervous system, psychological conflict, anxiety, defense, and functional symptoms. Neurasthenia was a more specific nineteenth- and twentieth-century diagnosis centered on nervous exhaustion, easy fatigability, weakness, reduced efficiency, and a variable group of physical and mental complaints. The relationship is therefore asymmetric: neurasthenia could be placed within wider neurosis-related classifications, while neurosis could never be reduced to neurasthenia alone.
For a modern reader, the second distinction is just as important. Neither “neurosis” nor “neurasthenia” is a current diagnosis in the American Psychiatric Association’s DSM-5-TR. The DSM-5-TR is the current DSM edition, published in 2022. In the World Health Organization system, ICD-10 retained neurasthenia as F48.0, while ICD-11 clinical guidance reorganizes the relevant territory and does not preserve neurasthenia as the same standalone category. Old labels therefore have to be interpreted historically before they are translated into present-day clinical language.
Neurosis vs Neurasthenia at a Glance
Neurosis: a broad historical umbrella whose meaning changed across medicine, psychiatry, psychoanalysis, and diagnostic manuals.
Neurasthenia: a narrower historical syndrome organized mainly around exhaustion, fatigability, weakness, reduced mental or physical efficiency, and associated somatic complaints.
Historical relationship: neurasthenia was often discussed as one form within the larger territory of nervous or neurotic disorders, but the exact hierarchy depended on the author and classification system.
DSM-5-TR status: neither neurosis nor neurasthenia is a current DSM-5-TR diagnosis.
ICD status: ICD-10 explicitly listed neurasthenia as F48.0; ICD-11 uses different categories and diagnostic requirements.
Modern interpretation: the symptoms once gathered under these labels may today lead to assessment for multiple psychiatric, neurological, sleep, medical, or other conditions. There is no one-to-one modern replacement for either historical term.
If you want the broader history and present-day meaning of the umbrella term, see Neurosis: What It Means Today, Symptoms, History, and Modern Diagnoses. For the historical taxonomy of named neurotic forms, see Types of Neurosis: Historical Categories and Their Modern Equivalents. This page keeps the narrower comparison intent: what neurosis and neurasthenia meant, how they overlapped, where they differed, and how to read those labels now.
What Did “Neurosis” Mean Historically?
The word neurosis is older than neurasthenia by about a century. Historical scholarship traces the term to the Scottish physician William Cullen. In Cullen’s eighteenth-century nosology, neurosis referred broadly to “nervous diseases.” The category belonged to a medical framework very different from twentieth-century psychoanalysis and from current psychiatric classification. The historical chapter by José M. López Piñero on the origin of the concept of neurosis emphasizes that Cullen’s usage should not be retrofitted with later meanings, and the psychiatric historical literature likewise treats Cullen’s concept as a product of eighteenth-century nervous medicine.
During the nineteenth century, “neurosis” was repeatedly reinterpreted as medicine changed its understanding of pathology, anatomy, function, and the nervous system. Some conditions once grouped among neuroses later acquired identifiable neurological or medical explanations. Other forms of distress increasingly became the territory of psychiatry and psychology. This long transition is one reason the word can look deceptively stable while its referent changes underneath it. A nineteenth-century physician, a Freudian analyst, and a mid-twentieth-century psychiatric manual could all use “neurosis” while meaning substantially different things.
By the twentieth century, neurosis was strongly associated in many psychiatric and psychoanalytic traditions with disorders characterized by anxiety, phobic avoidance, obsessions, compulsive phenomena, depressive symptoms, conversion or dissociative symptoms, and other forms of distress in people who were not described as psychotic. Even this summary is period-dependent. The history of the neurosis concept and the later controversies surrounding DSM classification show that neurosis was never one simple disease with one invariant symptom list.
What Did “Neurasthenia” Mean Historically?
Neurasthenia emerged much later and had a more fatigue-centered identity. George Miller Beard’s 1869 paper, “Neurasthenia, or Nervous Exhaustion”, is the landmark publication that established the diagnosis in American medicine. Beard and later physicians described a state of diminished nervous energy or exhaustion. The label spread widely in the late nineteenth and early twentieth centuries and became entangled with contemporary theories of work, modernity, urban life, heredity, sex, social class, race, gender, and civilization.
Modern historical reviews emphasize that neurasthenia was never completely uniform. Its symptom boundaries varied across clinicians, countries, and decades. A 2020 review, Neurasthenia: tracing the journey of a protean malady, describes a concept that changed across clinical, cultural, and sociological settings. The diagnosis could include physical exhaustion, mental fatigue, headaches, irritability, poor concentration, sleep disturbance, gastrointestinal complaints, sexual symptoms, autonomic complaints, pain, and a general sense of nervous weakness.
The diagnosis also outlived its late-Victorian peak in some settings. Historical hospital data from Queen Square in London show that neurasthenia remained in neurological practice into the early twentieth century before sharply declining. In Death of neurasthenia and its psychological reincarnation, Robert E. Taylor found that the label did not simply vanish because the experiences vanished; patients and symptom patterns were increasingly reclassified under other diagnoses. That is a useful historical finding, but it does not mean that every person once diagnosed with neurasthenia would receive the same modern diagnosis.
The Core Difference: Umbrella Category vs Fatigue-Centered Syndrome
The cleanest comparison is conceptual. Neurosis was a superordinate label in many historical systems. Neurasthenia was a more specific syndrome. A broad neurosis framework might contain anxiety states, phobic symptoms, obsessional phenomena, depressive states, hysterical or conversion phenomena, and other nonpsychotic disturbances. Neurasthenia, by contrast, was organized around exhaustion and reduced capacity, even though its associated symptoms could spread across mood, cognition, sleep, pain, digestion, sexuality, and autonomic functioning.
This difference explains why the two terms can overlap without being interchangeable. Saying that a historical clinician classified neurasthenia among neuroses does not make “neurosis” another word for fatigue. Likewise, calling a patient “neurasthenic” in an old record does not tell us that the patient had what a later psychoanalyst meant by a psychoneurosis. The historical system, date, country, and author matter.
The distinction also prevents a common modern error: treating “neurosis” as the psychological version of neurasthenia and “neurasthenia” as the physical version. Historical usage was more complicated. Both terms crossed mind-body boundaries, and both changed meaning. Their difference was primarily one of conceptual scope and symptom organization, not a timeless division between mental and physical illness.
How the Historical Symptom Profiles Differed
Symptoms commonly associated with neurasthenia
The most stable center of neurasthenia was fatigue or exhaustion. The WHO’s ICD-10 description of F48.0 emphasized persistent and distressing complaints of increased fatigue after mental effort or bodily weakness and exhaustion after minimal physical effort. Associated features could include muscular aches and pains, dizziness, tension headaches, sleep disturbance, inability to relax, irritability, dyspepsia, and concentration difficulties. ICD-10 also explicitly warned that depressive and anxiety disorders should be considered and that medical causes of fatigue had to be evaluated.
That ICD-10 description was itself a late historical stage of the concept, not a faithful copy of Beard’s nineteenth-century theory. It shows how the label survived after its original nervous-energy explanations had lost authority. It also shows why a symptom list alone cannot define the term across all periods. Beard’s neurasthenia, early twentieth-century European neurasthenia, culturally adapted forms of the diagnosis, and ICD-10 F48.0 belong to a lineage, but they are not identical constructs.
Symptoms historically gathered under neurosis
Neurosis never had an equally narrow symptom center. Depending on era and classification, the word could organize anxiety, fears and phobias, obsessional thoughts and compulsive acts, depressive symptoms, bodily complaints, conversion symptoms, dissociative phenomena, trauma-related reactions, and other forms of distress. The modern English Hub guide to neurosis symptoms explains why those historical manifestations should not be turned into a single twenty-first-century checklist.
Therefore, “Which has worse symptoms?” is not a meaningful historical question. Neurasthenia names a relatively circumscribed fatigue-centered pattern; neurosis names a broader and changing family. Severity could range widely within either label. Historical terminology did not provide a stable severity scale that allows the two words to be ranked.
Neurosis, Neurasthenia, and the Mind–Body Problem
Both concepts became important partly because they occupied territory where distress, bodily symptoms, nervous-system theories, and psychological explanations met. Neurasthenia is especially revealing. It could be described through exhaustion of nervous energy, constitutional weakness, overwork, modern life, infection, heredity, sexual behavior, or psychological factors, depending on the author and period. Those explanations were not equivalent, and many belonged to medical theories that are no longer accepted.
The gastric subtype illustrates this historical fluidity. A review of “neurasthenia gastrica” shows how late nineteenth- and early twentieth-century physicians debated interactions between nervous exhaustion and gastrointestinal symptoms. Such material is historically valuable because it shows how physicians built causal models around symptom patterns. It should not be used to infer that modern gastrointestinal disorders are forms of neurasthenia.
Neurosis underwent a parallel conceptual migration. As psychiatry and psychoanalysis developed, explanations increasingly emphasized psychological conflict, anxiety, defense, learning, and personality. This shift did not occur all at once, and biological, neurological, constitutional, and social explanations continued alongside psychological ones. The history is better understood as repeated reclassification than as a single discovery that replaced an earlier error.
Freud: Why Neurasthenia Was Not Simply “Neurosis”
Freud’s early writing is especially useful because it demonstrates the distinction from inside a major theory that later made neurosis central. In his 1895 paper on separating anxiety neurosis from neurasthenia, Freud argued that a particular anxiety syndrome should be detached from the broad field then called neurasthenia. He contrasted what he called “neurasthenia proper” with anxiety neurosis on symptom and etiological grounds.
This matters for terminology. In early Freudian theory, neurasthenia belonged to what Freud came to call the “actual neuroses,” while the psychoneuroses were theorized differently, with a larger role for psychological defense and conflict. Later psychoanalytic theory evolved further. The word “neurosis” therefore cannot be used as if Freud treated every named neurosis as one mechanism, and neurasthenia cannot be treated as a synonym for Freud’s mature concept of psychoneurosis.
The historical lesson is methodological: when a page, case history, or book says “neurosis,” ask whose theory is being used. When it says “neurasthenia,” ask which diagnostic tradition and period are involved. The labels only become clear after their framework is identified.
Neurasthenia Is Also Different From Psychasthenia
Neurasthenia and psychasthenia are frequently confused because their names sound alike and both circulated around the turn of the twentieth century. They were not the same construct. Neurasthenia was primarily organized around nervous exhaustion and fatigability. Pierre Janet’s psychasthenia was associated with obsessions, doubts, fears, compulsive phenomena, feelings of incompleteness, and his theory of reduced psychological tension or impaired “reality function.”
That distinction is relevant to this comparison because later readers sometimes collapse neurasthenia, psychasthenia, and obsessional neurosis into one antiquated category. Historically they had different theoretical centers. Modern OCD, anxiety disorders, depressive disorders, fatigue syndromes, and somatic symptom-related diagnoses likewise have their own current criteria and cannot be reconstructed by simply renaming one of these older labels.
How Diagnostic Classification Changed
From broad neurosis language to operational diagnosis
The most consequential twentieth-century change in American psychiatry came with DSM-III in 1980. The APA’s DSM history identifies DSM-III as a major revision, and the historical analysis by Bayer and Spitzer documents the controversy over the reduced role of psychodynamic formulations and the term neurosis. Their paper, Neurosis, psychodynamics, and DSM-III, shows that the change was not merely vocabulary editing; it reflected a new approach to diagnostic reliability and classification.
The result is why a historical diagnosis should not be translated by finding a single modern word that “replaced” it. Diagnostic systems reorganized the territory. Anxiety disorders, obsessive-compulsive and related disorders, trauma- and stressor-related disorders, depressive disorders, dissociative disorders, somatic symptom and related disorders, and other categories now divide phenomena that older frameworks could place under broad neurotic language.
DSM-5-TR
The current U.S. manual is DSM-5-TR, published in 2022. It does not use neurosis or neurasthenia as current diagnostic categories. A person presenting today with fatigue, anxiety, obsessions, depressed mood, bodily distress, sleep problems, or functional impairment would be assessed according to the actual pattern of symptoms, duration, severity, context, exclusions, and impairment rather than assigned a diagnosis of “neurosis” or “neurasthenia.” For a focused explanation, see Is Neurosis Still a Diagnosis? DSM-5-TR, ICD-11, and Modern Psychiatry.
ICD-10
ICD-10 preserved more of the older terminology. In the WHO’s mental and behavioral disorders guidance, F40–F48 was titled “Neurotic, stress-related and somatoform disorders,” and F48.0 was neurasthenia. The description required a fatigue-centered syndrome and differentiated it from depressive disorders, anxiety disorders, somatoform disorders, postviral fatigue syndrome, malaise and fatigue, and burnout. This is an important example of why the version number matters: a statement that was true of ICD-10 should not be silently transferred to ICD-11.
ICD-11
ICD-11, which came into effect for health reporting in January 2022, uses a substantially revised mental, behavioral, and neurodevelopmental classification. The WHO published the ICD-11 Clinical Descriptions and Diagnostic Requirements in 2024. Neurasthenia is not retained there as the same standalone mental-disorder diagnosis that appeared as F48.0 in ICD-10.
The relationship to ICD-11 bodily distress disorder requires careful wording. Revision literature describes bodily distress disorder as replacing ICD-10 somatoform disorders and absorbing part of the territory that had included neurasthenia. A comparison of ICD-10 and ICD-11 classification states that bodily distress disorder now includes neurasthenia, while the WHO-linked scientific discussion of bodily distress disorder emphasizes a new construct defined by persistent bodily symptoms accompanied by excessive attention and distress. This does not make ICD-11 bodily distress disorder a simple new name for neurasthenia.
That last distinction is essential. Many historical neurasthenia cases would not necessarily meet ICD-11 bodily distress disorder requirements. Some might be better understood through depressive, anxiety, sleep, neurological, medical, or other diagnoses; some might not meet criteria for any current mental disorder. Diagnostic mapping is a clinical assessment problem, not a word-substitution exercise.
What Do Neurosis and Neurasthenia Map Onto Today?
There is no single modern equivalent for neurosis, and there is no single modern equivalent for neurasthenia. Historical categories were heterogeneous, and current diagnostic systems are organized around different criteria. The safest translation is symptom- and context-based: identify what the historical clinician actually described, then compare those phenomena with current definitions without assuming identity.
The history of generalized anxiety shows how tangled this genealogy can be. A scholarly review notes that generalized anxiety was at one time counted among the many symptoms of neurasthenia and that DSM-III later split the older “anxiety neurosis” into generalized anxiety disorder and panic disorder. See The history of generalized anxiety disorder as a diagnostic category. This is a lineage of concepts, not proof that neurasthenia was “really GAD.”
Longitudinal research likewise shows why one-to-one translation fails. In a Zurich community study, neurasthenia overlapped substantially with depression and showed low longitudinal diagnostic stability. Cross-cultural research has also found substantial variation in what clinicians and patients meant by neurasthenia. A review of cross-cultural and conceptual issues concluded that the construct was heterogeneous and often overlapped with depression, chronic anxiety, and somatoform disorders.
These findings support a modern interpretive rule: overlap does not establish equivalence. Two diagnostic constructs can share fatigue, sleep disturbance, concentration problems, irritability, anxiety, or bodily symptoms and still differ in required features, exclusions, course, explanatory model, and treatment implications.
Neurasthenia vs Depression
Historical neurasthenia and modern depressive disorders can overlap in fatigue, reduced energy, impaired concentration, sleep disturbance, and diminished functioning. ICD-10 itself required clinicians to consider depressive illness when evaluating neurasthenia. The Zurich data also found strong overlap. Yet a depressive disorder is not defined by fatigue alone. Current diagnosis depends on the full syndrome, including mood and/or loss of interest or pleasure and the required pattern of accompanying symptoms, duration, impairment, exclusions, and clinical context.
Therefore, it is inaccurate to say that neurasthenia was simply an old name for depression. Some historical cases may resemble modern depression; others do not. The diagnostic categories arose from different systems and were used differently across settings.
Neurasthenia vs Anxiety Disorders
Anxiety could appear within neurasthenia, and historical anxiety concepts often overlapped with the larger neurosis field. But modern anxiety disorders are defined by specific patterns of fear, anxiety, avoidance, worry, panic, and associated impairment. Neurasthenia’s organizing feature was exhaustion rather than a specific fear or anxiety syndrome.
This is another reason to resist reverse diagnosis. A nineteenth-century description of nervousness, palpitations, poor sleep, and fatigue might invite comparison with an anxiety disorder today, but comparison is not retrospective diagnosis. The historical record may lack the information needed to apply modern criteria, and the meaning of the symptoms themselves may have changed with medical language and culture.
Neurasthenia vs ME/CFS, Fibromyalgia, and Other Fatigue or Pain Conditions
Neurasthenia has often been compared with chronic fatigue syndrome, now commonly referred to as ME/CFS in contemporary clinical and research contexts, and with fibromyalgia. Historical and conceptual similarities exist, especially around fatigue, weakness, pain, sleep, and impaired functioning. Reviews of neurasthenia discuss these similarities, and late twentieth-century studies directly examined overlap between ICD-10 neurasthenia and chronic fatigue presentations.
Similarity is not diagnostic identity. ME/CFS and fibromyalgia have their own contemporary definitions, evidence bases, differential diagnoses, and clinical management. The WHO’s ICD-10 description itself excluded postviral fatigue syndrome from F48.0 neurasthenia. A historical genealogy can illuminate why patients with persistent fatigue have been classified differently over time, but it cannot be used to relabel a current medical condition as “neurasthenia.”
The same caution applies to unexplained physical symptoms more generally. If you are reading an older record that calls someone neurasthenic, the label tells you how that clinician organized the case. It does not establish what contemporary medical testing, psychiatric assessment, sleep evaluation, or neurological examination would find.
Neurasthenia vs Burnout
Burnout and neurasthenia are sometimes linked because both can involve exhaustion and reduced capacity. Historically, authors have even described burnout as a successor concept in certain cultural narratives. That is an interpretive history, not a diagnostic equivalence. Burnout is tied specifically to occupational context in ICD-11 and is classified as a factor influencing health status or contact with health services rather than as a mental disorder.
A person can be exhausted from work, have a depressive disorder, have an anxiety disorder, have a sleep disorder, have a medical condition, meet criteria for another diagnosis, or have overlapping problems. Calling all exhaustion “neurasthenia” erases the distinctions that modern assessment is designed to make.
Neurosis vs Neurasthenia in Old Medical Records
If you encounter either word in a historical chart, family archive, military record, asylum record, psychoanalytic case, or early psychiatric textbook, treat the label as evidence about the classification system of its time. Do not begin by asking, “What is the modern diagnosis?” Begin by asking five narrower questions: What year was the label used? In which country and medical tradition? Which clinician or institution used it? What symptoms and functional problems were actually documented? What competing diagnoses were considered?
Only after reconstructing that context should modern comparison begin. A label such as neurasthenia may have been used for a fatigue-dominant presentation, but the same person’s record may contain anxiety, depressed mood, gastrointestinal symptoms, headaches, pain, sleep disturbance, or post-illness fatigue. A label such as neurosis may tell you even less about the precise symptom pattern unless a subtype is named.
This method protects against anachronism. Historical diagnoses are not merely obsolete words waiting for modern synonyms. They are classifications built from the knowledge, institutions, theories, and social assumptions of their time. Pietikäinen and Turunen’s study of diagnoses of distress across time is especially useful on this point: neurasthenia and later neuroses changed as psychiatry redistributed somatic and psychological forms of distress.
What the Comparison Means Clinically Today
In contemporary care, “neurosis” and “neurasthenia” are usually historical clues rather than sufficient diagnoses. If someone uses one of these words to describe current distress, the clinically useful task is to unpack the actual symptoms: fatigue, fear, panic, worry, obsessions, compulsions, low mood, sleep disruption, pain, dizziness, headaches, gastrointestinal symptoms, cognitive complaints, or functional decline. Each of those phenomena has a modern differential diagnosis.
Fatigue deserves particular care because it can occur in mental disorders, sleep disorders, medication effects, infections, endocrine and metabolic conditions, neurological illnesses, post-viral states, pain conditions, and many other medical contexts. New, severe, persistent, or functionally impairing fatigue should be evaluated on its own merits rather than explained by a legacy psychiatric term.
The same principle applies to physical symptoms historically called neurotic or neurasthenic. The English Hub article on physical symptoms of neurosis and modern differential diagnosis explains why historical somatic language should not be used to dismiss current bodily complaints. A psychological formulation can be appropriate when supported by assessment, but it is not a substitute for the medical evaluation indicated by the presentation.
Treatment Implications: Treat the Current Problem, Not the Historical Label
There is no current evidence-based treatment protocol for “neurosis” as one diagnosis because DSM-5-TR does not define such a disorder. Likewise, treatment recommendations written for historical neurasthenia cannot simply be transferred to a modern patient. Nineteenth-century neurasthenia was treated with approaches ranging from rest cures and electricity to exercise, diet, travel, and other interventions grounded in theories that changed dramatically over time.
Modern treatment follows the condition actually identified. Evidence-based care may differ substantially for a depressive disorder, generalized anxiety disorder, panic disorder, obsessive-compulsive disorder, insomnia, ME/CFS, fibromyalgia, bodily distress disorder, a neurological condition, or a medical cause of fatigue. The category matters because diagnosis guides which evidence base is relevant.
This is also why self-diagnosing “neurasthenia” from an old symptom checklist is unhelpful. The checklist cannot perform the differential diagnosis. It cannot tell whether fatigue is psychiatric, medical, sleep-related, medication-related, post-infectious, mixed, or unexplained. Historical vocabulary can organize research and understanding; clinical decisions require current assessment.
Common Misconceptions
“Neurosis and neurasthenia are the same thing.”
They are historically related but conceptually different. Neurosis was a broad, changing category. Neurasthenia was a narrower exhaustion-centered syndrome.
“Neurasthenia was just anxiety.”
Anxiety was often present, but neurasthenia was not defined simply as anxiety. Freud’s attempt to separate anxiety neurosis from neurasthenia is direct historical evidence that contemporary clinicians were already distinguishing them.
“Neurasthenia was just depression.”
Historical and epidemiological research shows substantial overlap with depression, but overlap is not identity. Many neurasthenia presentations did not map cleanly onto depressive disorders.
“Neurasthenia is the old name for ME/CFS.”
The two have been compared historically because both can involve disabling fatigue, but they are not interchangeable diagnostic labels. ICD-10 explicitly separated postviral fatigue syndrome from neurasthenia.
“If a diagnosis disappeared, the symptoms were imaginary.”
Diagnostic categories can disappear while the underlying suffering remains real. Historical work on neurasthenia shows patients being redistributed into new categories as medical classification changed. A change in nosology changes the explanatory and diagnostic frame; it does not erase the patient’s experience.
“Neurosis is still a formal modern diagnosis because people still use the word.”
Everyday, historical, and psychoanalytic usage can persist after a term leaves a current diagnostic manual. Clinical diagnosis depends on the classification actually in use. For the U.S. DSM system, that means DSM-5-TR; for WHO international classification, that means ICD-11, with country-specific implementation and coding practices.
A Practical Translation Rule for Modern Readers
When you see “neurosis,” translate it first as: “a historically variable umbrella term; identify the period, subtype, and theory before mapping it.” When you see “neurasthenia,” translate it first as: “a historical fatigue- and exhaustion-centered diagnosis; identify the diagnostic system and documented symptoms before comparing it with modern conditions.”
That two-step rule is more accurate than replacing either word with a current diagnosis. It keeps the historical meaning intact and still allows modern clinical interpretation. It also respects the fact that current diagnostic categories were built with different criteria and often cut across older boundaries.
FAQ
Are neurosis and neurasthenia the same?
No. Historically, neurosis was the broader and more variable category. Neurasthenia was a more specific syndrome centered on nervous exhaustion, fatigability, weakness, and reduced efficiency. Their relationship depended on the period and classification system.
Was neurasthenia a type of neurosis?
In many historical frameworks, yes: neurasthenia was placed within the larger territory of nervous or neurotic disorders. But that statement is system-specific. Freud, ICD-10, and nineteenth-century neurologists did not use exactly the same taxonomy.
Is neurasthenia a diagnosis in DSM-5-TR?
No. DSM-5-TR, the current American Psychiatric Association manual, does not contain neurasthenia as a current diagnosis. Modern clinicians assess the actual symptom syndrome and differential diagnosis.
Is neurosis a diagnosis in DSM-5-TR?
No. Neurosis is not a current DSM-5-TR diagnostic category. It remains important in psychiatric history, psychoanalytic theory, and ordinary language.
Was neurasthenia in ICD-10?
Yes. WHO ICD-10 listed neurasthenia as F48.0 within the broader F40–F48 grouping “Neurotic, stress-related and somatoform disorders.” Its clinical description centered on mental or physical fatigue and required differential diagnosis from depression, anxiety, medical causes of fatigue, and related conditions.
Is neurasthenia still in ICD-11?
ICD-11 does not retain neurasthenia as the same standalone mental-disorder category used in ICD-10. Some of the old diagnostic territory was reorganized, including within the development of bodily distress disorder, but that category is not a one-to-one replacement for neurasthenia.
Is neurasthenia the same as chronic fatigue syndrome or ME/CFS?
No. Historical descriptions overlap in some symptoms, particularly fatigue and impaired functioning, but ME/CFS is a contemporary condition with its own definitions and evidence base. Historical resemblance does not establish diagnostic identity.
Can neurasthenia be caused by stress?
Historical theories frequently linked neurasthenia with overwork, strain, modern life, or stress-like concepts. Those explanations belonged to changing medical theories. In modern practice, stress can contribute to fatigue and distress, but persistent fatigue still requires a broad differential assessment rather than a historical diagnosis.
What did Freud mean by neurasthenia?
In Freud’s early theory, neurasthenia was not identical to psychoneurosis. He separated anxiety neurosis from neurasthenia and later grouped neurasthenia among the “actual neuroses,” distinguishing these from psychoneuroses that he explained through different mechanisms.
If an old medical record says “neurasthenia,” what does that mean today?
It means the clinician used a historical diagnostic category. To interpret it, examine the date, country, theoretical tradition, recorded symptoms, and differential diagnosis. A modern diagnosis cannot be inferred from the label alone.
