Sigmund Freud, after studying under Charcot, theorized the symptoms as a conversion of repressed libidinal impulses into physical form, which brought about its current title of conversion disorder.
In the 19th century, the phenomenon became a passion of French neurologist Jean Charcot, who identified it primarily as a neurological disorder with psychological underpinnings that could, in some cases, be treated by hypnosis.

Update on Psychogenic Nonepileptic Seizures This theory eventually lost prominence as symptoms of hysteria were increasingly reported in males. Because of its observed frequency in females, hysteria was conceptualized as the result of a “wandering uterus” that had been displaced in the body and subsequently inhabited other organs and appendages, applying pressure and leading to the manifestation of physical symptoms. Equally as varied were the many hypotheses for the causes of hysteria. PNES has a long history in the medical literature, where it has been described by several aliases, the most common being hysteria. It is not uncommon to see both PNES and epileptic seizures in the same patient. The last has largely fallen out of favor because of the pejorative nature of the term “pseudo,” which may imply that the symptoms are not real and therefore undermine the impact of the disorder on a patient’s life.
Alternate names frequently used for PNES are non-epileptic attack disorder, functional seizures, stress seizures, psychogenic seizures, and pseudoseizures. When coding for PNES as a conversion disorder using ICD-10, the diagnosis must include the specifier “with attacks or seizures” (ICD-10 code F44.5) to differentiate it from other conversion symptoms (eg, dysarthria, sensory loss), which are coded separately. PNES is classified as a subtype of conversion disorder under the category, somatic symptom and related disorders in DSM-5. Instead, they are thought to have an underlying psychological cause. Although psychogenic non-epileptic seizures (PNES) are events that appear to be similar to seizures, they are not caused by abnormal electrical brain activity.
