Is hysteria still a diagnosis?

Not as a term. Current classifications use functional neurological disorder (DSM-5-TR: functional neurological symptom disorder; ICD-11: dissociative neurological symptom disorder). The word "hysteria" is considered outdated and unhelpful.

Does it only affect women?

No. It affects men and women of all ages, and historically it was more often reported in women. Modern studies show a wide spread across sexes.

Can stress or trauma cause it?

Often, yes, but not always. Stress, injury, illness and trauma are commonly reported triggers, and some people have no clear trigger at all.

Are the symptoms faked?

No. Symptoms are involuntary and real. Faking to gain something is a separate condition and is uncommon in these presentations.

Can it go away on its own?

Some people improve without specific treatment, especially early on. But for many, symptoms last months or years without rehabilitation. Early specialist input improves the chance of recovery.

How can family members help?

Be calm and supportive. Avoid "just snap out of it" and avoid excessive protection. Encourage the exercises and sessions, and take part in the explanation.

Can FND and epilepsy occur together?

Yes, though it is less common than either alone. This is one reason a video-EEG assessment in a specialist unit matters before a diagnosis is settled.

Who should I see first?

A neurologist for a full neurological assessment, ideally one with experience of FND. A psychiatrist can help with the stress, anxiety, mood and trauma that often accompany it.

Opening

"The doctors say nothing is wrong. But I cannot walk."

Ruksana was nineteen, a first-year college student from Muzaffarpur. After a loud family argument about her marriage, she woke one morning with her legs refusing to hold her. Three neurologists found nothing on scans or tests. Her family, hearing the phrase "it may be stress", concluded she was pretending. She came to us in a wheelchair, frightened and humiliated. "I'm not lying," she said. "Why would I choose this?"

Details are blended and altered so that no individual can be identified.

Ruksana's question is the one this article tries to answer. The symptoms were real. The brain was working. What had gone wrong was the way the brain was controlling movement, and the old word that once described her condition has, for good reason, been dropped. Today it is called functional neurological disorder (FND).

Three names for one long story

Hysteria

The old word. Ancient physicians linked it to the womb. Discredited, and rightly so: it blamed women's bodies and dismissed real suffering.

Conversion disorder

Freud and Breuer's idea (1895): distress "converted" into physical symptoms. Still widely used, but the mechanism it describes is now seen as too simple.

Functional neurological disorder

The modern term: genuine neurological symptoms with a disorder of how the brain and nervous system function, not of their structure. Used by neurologists and psychiatrists worldwide.

Figure 1. Three names, one condition family. In DSM-5-TR the term is "functional neurological symptom disorder"; in ICD-11 it is "dissociative neurological symptom disorder".⁴⁵ Both drop the old "conversion" label.

What the word hysteria tells us about us

Hystera: the Greek word for the womb

For over two thousand years, doctors blamed strange fits, paralysis and fainting in women on a "wandering womb". The word stuck; the idea did not.

Historical reviews note that hysteria has been described in ancient Egyptian papyri and in the writings of Hippocrates; its link with the uterus persisted for centuries and shaped who was believed to be affected.² In the nineteenth century, the French neurologist Jean-Martin Charcot showed the symptoms in public demonstrations, and his student Sigmund Freud developed the theory that stress turned into bodily symptoms. Pierre Janet proposed that the mind could split off (dissociate) parts of experience. Those ideas shaped the word we use today. But the path from womb to brain is also a path away from blame.

A short history

Five eras of an old illness

Ancient times
Egyptian and Greek writings describe fits, paralysis and breathlessness in women. The explanation: a womb that moves around the body and "suffocates" it. Treatments included scents, marriage and pregnancy.
17th to 18th centuries
Thomas Sydenham, the "English Hippocrates", recognised hysteria as a real illness that could affect men as well as women: an important step, though the womb explanation survived.
1870s to 1890s
Charcot's clinic at the Salpêtrière in Paris studied and photographed patients. Freud and Breuer's Studies on Hysteria (1895) introduced "conversion": distress turned into bodily symptoms.
1952 to 1980
DSM-I and DSM-III adopt "conversion" as a psychiatric diagnosis. Hysteria as a term fades from formal use, but the concept persists in clinical practice and popular culture.
2013 to 2022
DSM-5 renames it "functional neurological symptom disorder"; ICD-11 (in force from 2022) calls it "dissociative neurological symptom disorder". Neurology and psychiatry now share the condition, through functional brain science.

Why the old word was dropped

Hysteria was never one disease. It was a catch-all for distress, women, and anything the physician could not explain. Calling a patient "hysterical" often meant "not taken seriously". Neurologists writing in the British Journal of Psychiatry have argued that a diagnosis made on positive signs, not on what is "left over" after tests, is more accurate and more respectful.² A systematic review found that since the 1970s such diagnoses have rarely been overturned later.³ The change in name was a change in how we treat patients.

The name, then and now

Then: "hysteria"

Explained by: a wandering womb.

Who was affected: mostly women.

Clinical response: often dismissal, marriage, or confinement.

Mid-century: "conversion"

Explained by: repressed distress turned into symptoms.

Who was affected: anyone, but still often labelled.

Clinical response: psychotherapy, sometimes without neurological reassessment.

Now: "FND"

Explained by: altered brain networks, expectations and stress.

Who was affected: all ages and sexes.

Clinical response: positive diagnosis, physiotherapy, CBT and family work.

Figure 2b. How the explanation, the people affected and the response have changed. Simplified for lay readers.

What it looks like today

Symptoms that are real, varied, and neurological

Any part of the nervous system can be involved: seizure-like episodes, speech and voice, numbness and pins and needles, weakness or paralysis, tremor and jerks, gait and balance, and leg weakness.

Form	What people experience
Functional movement disorder	Limb weakness, tremor, jerky movements, dystonia (twisting), trouble walking that doesn't match the neurology
Functional seizures	Convulsion-like or collapse episodes without the EEG changes of epilepsy; among the most common forms seen in specialist clinics
Functional sensory symptoms	Numbness, tingling, loss of vision or hearing, sudden pain
Functional speech disorder	Loss of voice, stammering, or difficulty speaking with no structural cause
Functional gait disorder	Abnormal walking or balance, often with a fear-of-falling component

Figure 3. Common symptom zones and forms. Each form is a recognised presentation in current classifications. Frequencies vary between clinics and countries.⁸

Symptoms often start suddenly, after stress or injury, and may fluctuate: better when distracted, worse when watched. That pattern is a clue, not a proof.

"Functional" does not mean "fake"

Patients with these symptoms are not pretending, and clinicians do not believe they are. The symptoms are involuntary, cause real disability, and are not intended. The "functional" in the name refers to how the system works, not to whether the suffering is genuine. Malingering (faking for gain) is a different thing, and is rare in these presentations.

The new-age perspective

The brain as a prediction machine

The most exciting modern idea is that the brain does not simply receive signals from the body. It constantly predicts what it expects to feel and do, then checks those predictions against incoming information. When the prediction is strong and the signal is unclear, the prediction can win. Researchers call this a predictive or Bayesian model.⁶

Expectation"My legs will give way" (prior belief, fear, past injury)
Movement planbrain sends the signal to move the leg
Body feedbackmuscles, joints, balance sensory signals

Figure 4. A simplified predictive-processing loop, after Edwards and colleagues (2012). Feedback is compared with expectation; if the expectation dominates, the movement may fail. The idea is that strong expectations, stress and attention can shape what the brain sends to the muscles, without any damage to the nerves themselves.

Three new-age lenses on the same condition

1 · Brain networks

Imaging studies show altered activity in networks for movement, attention, emotion and body awareness in people with FND. The disorder appears to involve how these networks talk to each other, not a single "broken" area.

2 · Trauma and stress

Stressful life events, physical injury and adverse childhood experiences are often reported in FND histories. Family conflict is often a trigger, as in a 2025 case report from Lahore in which symptoms cleared after 18 months of combined care.⁹

3 · Social spread

Outbreaks of tic-like or functional symptoms among groups of teenagers have been described, and some researchers link them to online videos. This "social transmission" is still being studied, but it shows how expectations and attention can spread through a group.

When trauma sits underneath, it deserves care in its own right; our guide to complex PTSD: symptoms, causes and treatment explains how long-standing trauma shows up in the body and mind.

Diagnosis

From "rule out" to "rule in"

For decades, a doctor reached a functional diagnosis by excluding everything else, and then, often, with a shrug. That approach misses people and wastes years. Modern practice looks for positive signs: features in the neurological examination that show the symptom is inconsistent with known disease.¹ Examples include a weakness that changes when the patient is distracted, a tremor that stops when the same limb moves in a different pattern, or a seizure-like episode with features that differ from epilepsy.

"It's all in your head."

No. The symptoms are generated by the nervous system, however they arise. Telling patients this is a physical-and-psychological problem helps them engage with treatment.

"Once it's functional, there's nothing to check."

Wrong. A functional diagnosis is made after proper tests and examination, and is revisited if new features appear. Some patients do have epilepsy or other disease later.

"Psychiatric problems cause it."

Not always. Many people with FND have no diagnosed psychiatric illness. Stress is common, but it is not the whole explanation.

"Epileptic seizures and psychogenic ones look the same."

Often not. Only video-EEG monitoring in a specialist unit reliably tells them apart. Guessing from a video at home is unsafe for diagnosis.

Please do not self-diagnose or dismiss a symptom.

New weakness, collapse, fits, loss of consciousness, speech change, or sudden loss of vision are medical emergencies until proven otherwise. Go to a neurologist or hospital promptly. A functional diagnosis can only be made by a clinician after the right assessment.

What the assessment in India might include

A neurological examination, MRI and blood tests as indicated, EEG (including video-EEG where seizures are possible), a psychiatric and trauma history, and a careful look at family and work stress. In my practice, I also ask about sleep, alcohol, medicines, and any previous "fits" or fainting. A good assessment ends with an explanation the patient can understand and a plan. Our Patna team works with neurologists to make sure no physical cause is missed.

At the clinic, this assessment is offered through our neuropsychiatry service in Patna. Where fits are part of the picture, see our epilepsy assessment and treatment page, and for other conditions where brain and mind overlap, care for neuropsychiatric illness.

Treatment

What the evidence supports now

Treatment has moved from waiting for symptoms to fade, towards active rehabilitation. The most strongly supported approaches combine specialist physiotherapy, cognitive behavioural therapy and clear explanation. Each reshapes the predictions that drive the symptoms.

Specialist physiotherapy (motor symptoms)

Strongest for limb & gait symptoms

Randomised trials: about 72% of patients improved vs 18% in usual care at 6 months (Nielsen 2017)

CBT adapted for FND

Good evidence, growing

Trials show better function and fewer seizures in several groups; most effective combined with physio

Clear, supportive diagnosis

Essential first step

Explaining the diagnosis positively is part of nearly every effective programme

Multidisciplinary rehab programmes

Promising, mostly open studies

An 8-week outpatient programme combining physio, CBT, self-management and psychoeducation reduced symptoms in a published cohort of 50

Medicines

None

No specific treatment for FND itself; used only for co-existing depression, anxiety, or sleep problems, as prescribed

Figure 5. The evidence landscape, graded in plain terms.⁷¹⁰ Bar lengths are illustrative of the strength of evidence, not effect sizes.

1Explain the diagnosis
Describe the symptoms as real, nervous-system based and treatable, without blame.
2Retrain movement
Specialist physiotherapy: retrain movement and confidence, often in intensive short blocks.
3Reshape predictions
CBT for the fear, stress and expectation that feed the symptoms; gradual return to activities.
4Involve the family
Family members learn to respond supportively: not over-protect, not dismiss, and not watch every move.

What happens in a course of cognitive behavioural therapy (CBT), and why it works on expectations and fear, is explained in our CBT guide.

What happened to Ruksana

Ruksana had a neurological review, MRI and EEG, all of which were normal. We explained the diagnosis together with her family, referred her to a physiotherapist trained in functional movement disorders, and began weekly sessions of CBT focused on the fear of falling and the family conflict. Over four months she moved from a wheelchair to a frame, then to walking with a stick. Her parents came to two sessions. "I thought she was being dramatic," her father said quietly. "Now I know she was being brave."

Before your appointment

Questions to ask your neurologist

Could this be a functional symptom, and what are the positive signs?
Do I need EEG or video-EEG to rule out epilepsy?
Is there a physiotherapist or rehab team who treats this?
Should I see a psychiatrist for stress, anxiety or sleep?
What signs should prompt me to come back urgently?

Go to emergency care now if...

sudden weakness of one side of the body, face droop or slurred speech
a first fit, or a fit lasting over five minutes
collapse with injury, or unconsciousness
sudden loss of vision or speech
any symptom with chest pain, breathlessness or confusion

Call 112 or 108. These can be serious even when a cause is later found to be functional.

For stress, anxiety, mood or trauma alongside functional symptoms, you can book a consultation in Patna or online.
