Hysteria: Clinical manifestations of consciousness and emotional disorders. Consciousness disorder is mostly seen in a hazy state, with a reduced range of consciousness, some in a dream-like state or Moet state. Various defensive reflexes are always present in the disorder of consciousness, and are related to strong emotional experiences, and can have emotional outburst symptoms such as crying, laughing, rolling, chest pounding, shouting and so on. Sometimes it is dramatic, and the content of the speech is related to the inner experience, so it can be easily understood. Psychiatric factors are often evident before the onset of this type of disorder. Despite the patient’s denial, the episodes are often seen by others as a way to get out of a difficult situation, vent repressed emotions, gain sympathy and attention from others, or receive support and compensation. In recurrent episodes, onset is often achieved by recalling and associating events or situations related to previous traumatic experiences. According to the clinical characteristics, this type can be divided into the following categories DSM-III and IV according to their clinical manifestations: dissociative amnesia, dissociative somnambulism, multiple personality, depersonalization disorder and atypical dissociative disorder. Dissociative disorders: acute onset of narrowing of consciousness, emotional outbursts of ventilatory nature, selective amnesia and self-identification disorder, self-impairment is often prominent and episodic in nature, and after the episode, consciousness returns to normal rapidly. Dissociative amnesia, dissociative somnambulism, dissociative xylophobia, dissociative trance and possession, dissociative identity disorder (dual personality, alternate personality), others (affective outbursts, pseudodementia, ganser syndrome, child-like dementia hysterical psychosis). Conversion disorders: mainly manifested as random motor and sensory dysfunction suggesting that the patient may have some neurological or somatic disorder but impairing its signs and symptoms do not correspond to the anatomical and physiological features of the nervous system and are considered to be internal conflicts and desires that the patient cannot resolve Symbolic conversion can be of the following common types. Motor disorders: limb paralysis, limb tremors, inability to get up and walk, mutism, aphasia) spastic disorders, convulsive grand mal seizures sensory disorders (sensory physical examination neurological examination and laboratory tests do not reveal corresponding organic deficits in their internal organs and nervous system, sensory hypersensitivity, abnormalities, visual disturbances, auditory disturbances). (1) Collective onset of hysteria: Also known as epidemic hysteria, girls aged 11 to 15 are most likely to suffer from the disease, mostly in groups that live together, such as schools, churches, monasteries, or in public places. The lack of understanding of the nature of the disorder often causes widespread nervousness and fear in the group, resulting in a short-term epidemic of hysteria under the influence of mutual suggestion and self-suggestion. Most of these hysterical episodes are short-lived and have similar manifestations. The epidemic can be quickly controlled by isolating the patients, especially the first cases, and treating them symptomatically. Most of the patients are young women who are mentally stressed, overworked, sleep deprived, and prone to menstruation, as well as those with performative personality traits. The appearance of exaggerated or persistent symptoms is generally not dictated by the person’s will but by unconscious mechanisms. These cases involving claims for compensation should be dealt with as early as possible in an effort to resolve them completely and should not be delayed in conjunction with psychotherapy to promote the elimination of symptoms. (3) occupational neurosis: this is a type of occupational-related motor coordination disorder, in which the muscles are tense and painful, so that the finger movement is slow and strenuous or bouncing; in severe cases, due to muscle tremors or spasms, the forearm or even the entire upper extremity of the finger cannot be used to give up using the hand or change to other manual activities, then the finger movement returns to normal. In addition to coordinated finger movements, these symptoms can also be manifested as stuttering after stressful speech training. It is advisable to put the patient in a state of mental relaxation and then to train the corresponding muscle coordination functions in a gradual manner, from simple to complex. Analytical, behavioral therapy, family therapy, medications: Differentiation between epilepsy and hysteria: Hysteria: with psychological factors, variable content, can speak, clear consciousness can be hazy, no incontinence, eye avoidance, eyelid impedance, no bite, no fall, several minutes for several hours, many people in a safe place, no sleep attacks. EEG is normal. Epilepsy: no psychological factors, fixed content, never speech, loss of consciousness, incontinence, no eye avoidance, no eyelid impedance, bite, fall, several minutes, no choice of place, sleep may seize. EEG abnormalities.
