【Basic Knowledge of Occupational Health】Hysteria

Hysteria (disociative-conversion disorder) is a mental disorder caused by psychological factors such as life events, internal conflicts, suggestions, or self-suggestions, acting on individuals who are prone to it. The main manifestations of hysteria are dissociative symptoms and conversion symptoms. Separation refers to a situation in which past experiences do not fully or partially align with one’s current environment and sense of self-identity. Conversion refers to an emotional reaction triggered by psychological stress, followed by the appearance of physical symptoms; once these physical symptoms emerge, the emotional reaction fades away or disappears. The physical symptoms in such cases are known as conversion symptoms. To diagnose conversion symptoms, it is necessary to rule out any organic lesions.

Also known as hysteria or hysteric neurosis, it is a type of psychoneurotic disorder; it usually manifests between the ages of 16 and 30, with females being more affected. Its special personality traits (i.e., hysterical personality traits) constitute an important basis for the onset of the disorder; patients often exhibit high emotional sensitivity, susceptibility to suggestion, and a tendency toward fantasy. Sudden or prolonged mental stressors are also common triggers, such as panic, remorse, anxiety, etc., with anger and sadness being particularly likely to trigger the disorder when they cannot be expressed. Subsequent episodes usually occur when the person recalls the circumstances of the initial episode or experiences similar emotional states. Furthermore, when patients suffer psychological trauma, conditions such as physical weakness and illness, prolonged fatigue, head injuries, as well as periods in women’s lives such as menstruation or postpartum, can also trigger this disease. Its onset is often sudden, and the clinical manifestations are complex and varied, but mainly consist of sensory, motor, and mental disorders. Sensory disturbances are often manifested as numbness in the limbs, but their pattern cannot be explained by the anatomical and physiological properties of nerves. In the case of hyperesthesia, even a light touch often causes severe pain or unusual discomfort. Special sensory disturbances commonly include deafness and blindness, while motor disorders manifest as seizure episodes – such as falling to the ground with convulsions and uncontrolled movements of the limbs; or the limbs remaining straight, with opisthotonos, or behaviors like pulling at one’s hair or clothes and making strange noises. Consciousness and bladder/bowel function remain normal during these episodes. It may result in paralysis, with types including monoplegia, hemiplegia, and paraplegia; all of these are flaccid types without pathological signs. Mental disorders often manifest as emotional outbursts, with patients suddenly crying or laughing uncontrollably, hitting their heads, biting their clothes, pounding on their chests and feet, rolling around on the ground, or saying things that are difficult to understand. The above manifestations during an episode are characterized by the following features: the patient’s defensive responses are normal, allowing them to avoid painful stimuli and self-harm automatically; the duration of the episode depends entirely on the surrounding environment as well as people’s words and attitudes; episodes are often accompanied by strong emotional elements, with all manifestations having a performative and exaggerated nature; they are highly susceptible to suggestion – that is, they can suddenly worsen after being suggested to do so, or they can improve suddenly or even disappear; there are no symptoms such as drowsiness or headache after the episode; except in cases where epilepsy is also present, no epileptic waves are detected on the electroencephalogram during the episode.
