“Female hysteria” no longer exists as a diagnosis. It was officially removed from the Diagnostic and Statistical Manual of Mental Disorders (DSM) in 1980, when the third edition replaced the umbrella concept of “hysterical neurosis” with several more specific, gender-neutral conditions. The symptoms once lumped together as hysteria are now recognized across at least three distinct diagnoses: functional neurological disorder, somatic symptom disorder, and dissociative disorders. Many cases historically labeled hysteria were also simply undiagnosed physical illnesses.
Why Hysteria Was Abandoned
For centuries, hysteria was tied to the uterus (the word itself comes from the Greek “hystera,” meaning womb) and applied almost exclusively to women. The diagnosis covered an impossibly broad range of symptoms: seizures, paralysis, anxiety, fainting, irritability, insomnia, pain with no apparent cause, and emotional outbursts. Essentially, if a woman had symptoms a doctor couldn’t explain, hysteria was the default label.
By the mid-20th century, psychiatry recognized that this catch-all approach was both scientifically useless and deeply biased. The 1980 DSM-III broke the concept apart. Rather than one vague diagnosis rooted in gender, the new system created categories based on the actual pattern of symptoms a person experienced. The shift also acknowledged that men could have the same symptoms, something the hysteria framework had largely ignored.
Functional Neurological Disorder
The closest modern equivalent to the physical symptoms of hysteria is functional neurological disorder (FND), previously called conversion disorder. The old name came from a Freudian idea that psychological distress “converted” into physical symptoms. Research has since shown that explanation is incomplete. Brain imaging reveals that people with FND have measurable changes in how their brain sends and receives signals, and not everyone with the condition has a history of trauma or stress.
FND causes real neurological symptoms like weakness, paralysis, tremors, seizures, numbness, or difficulty speaking, but standard neurological tests don’t find structural damage like a stroke or tumor. Instead, diagnosis relies on specific clinical signs showing that the symptom pattern is internally inconsistent with known neurological diseases. The DSM-5-TR requires that these symptoms cause significant distress or impairment in daily life and that no other medical or mental health condition better explains them.
The condition is more common than many people realize. A 2024 systematic review estimated the incidence of FND at 10 to 22 new cases per 100,000 people each year, with a minimum prevalence of 80 to 140 per 100,000. Applied to a country like the UK, that translates to at least 50,000 to 100,000 people living with the condition. Most studies likely undercount because of diagnostic challenges and the lingering stigma around symptoms that don’t show up on standard tests.
Somatic Symptom Disorder
Another piece of what was once called hysteria now falls under somatic symptom disorder (SSD). This diagnosis applies when a person has one or more physical symptoms, whether or not they have a known medical cause, accompanied by excessive worry, anxiety, or behavioral changes focused on those symptoms. The distress or preoccupation must persist for more than six months.
A key change in the DSM-5 was dropping the old requirement that symptoms be “medically unexplained.” Earlier editions had essentially required doctors to prove a negative, that no physical cause existed, before making the diagnosis. The current criteria focus instead on the person’s disproportionate thoughts, feelings, and behaviors around their symptoms. This shift was meant to reduce the adversarial dynamic where patients felt dismissed and doctors felt pressured to rule out every conceivable condition before offering help.
Dissociative Disorders
When the DSM-III retired hysteria in 1980, it explicitly reclassified hysterical symptoms as manifestations of dissociative disorders. These conditions involve disruptions in consciousness, memory, identity, or perception. Someone might experience gaps in memory, feel detached from their own body, or have episodes where they lose awareness of their surroundings. The international classification system (ICD-10) also grouped functional neurological symptoms under dissociative disorders, reflecting the overlap between these categories.
Histrionic Personality Disorder
The behavioral and emotional traits once attributed to hysteria, rather than the physical symptoms, were partly absorbed into histrionic personality disorder. The name preserves the etymological link. People with this diagnosis show a persistent pattern of excessive emotionality and attention-seeking: being overly dramatic, easily influenced, highly sensitive to criticism, and uncomfortable when not the center of attention. Importantly, this is a personality disorder diagnosis, not a condition defined by physical symptoms. It applies to a stable pattern of behavior across many situations, not to episodes of illness.
Conditions Misdiagnosed as Hysteria
A significant number of women historically diagnosed with hysteria almost certainly had identifiable medical conditions that doctors either couldn’t or didn’t bother to diagnose. Epilepsy, multiple sclerosis, endometriosis, lupus, thyroid disorders, and autonomic conditions like postural orthostatic tachycardia syndrome (POTS) all produce symptoms that overlap with what doctors once called hysteria. Chronic pain conditions, migraines, and autoimmune diseases were routinely dismissed when they occurred in women.
This history continues to affect healthcare. Research consistently shows that women wait longer for diagnoses of serious conditions, are more likely to have pain attributed to psychological causes, and are less likely to receive aggressive treatment for the same symptoms as men. The legacy of hysteria didn’t vanish when the word left the textbooks. Understanding that the diagnosis was retired for good reason can help patients advocate for thorough evaluation when their symptoms are being minimized.
How FND Is Treated Today
Treatment for functional neurological disorder looks nothing like the rest cures, hydrotherapy, and institutionalization that defined the hysteria era. Modern care is typically multidisciplinary, involving neurologists, mental health professionals, and rehabilitation therapists working together.
For some patients, simply receiving a clear explanation of what FND is and confirmation that their symptoms are real, not imagined, is itself therapeutic. Beyond education, physical and occupational therapy are first-line treatments, focused on retraining movement patterns and gradually increasing function. Speech therapy helps when symptoms affect speaking or swallowing. Psychological approaches, including cognitive behavioral therapy and stress-reduction techniques like progressive muscle relaxation and breathing exercises, address the mental health dimensions without implying the symptoms are “all in your head.”
The renaming from conversion disorder to functional neurological disorder was itself partly therapeutic. The old name implied a psychological mechanism that couldn’t always be identified and carried the stigma of the hysteria diagnosis it descended from. The current name simply describes what’s happening: the nervous system is functioning abnormally, even without structural damage. That framing makes it easier for patients to engage with treatment and for clinicians to take the condition seriously.
