- a disease with polymorphic symptoms, manifested by functional somatic, neurological and mental disorders. These various disorders arise in connection with the increased suggestibility and self-suggestibility of the patient. Therefore, the symptoms of hysteria can resemble the manifestations of various diseases, for which it was called the "great simulator". Hysterical neurosis often occurs in individuals with a hysterical nature (see Psychopathy).
Of the symptoms of the disease, the most prominent are hysterical convulsive seizures, which are now quite rare. There is usually a seizure in the presence of spectators and in a place where the patient cannot inflict damage. Consciousness does not turn off, but rather narrows. The patient does not fall anywhere, but chooses a pre-place, so as not to hit (before falling, "straws underlay"). Convulsive manifestations are not constant and diverse. Movements are sweeping and chaotic. It so happens that the patient's body (more common in women) is curved in the form of an arc. If the patient is lying in bed, then the legs and arms are pulled out, the fingers are cramping ("obstetrician's hand"). Seizures can be without seizures, in the form of various crises (hypertonic, cardiac), attacks of suffocation, trembling in the body ("shaking"), long sobs. Symptoms such as paralysis of the arms and legs, loss of sensation of the type of “gloves”, “socks”, gait disturbances are quite common. Hysterical blindness, deafness, and dumbness occur somewhat less frequently. The patient is silent when asked questions, but answers them in writing, unlike the deaf and dumb. Patients with hysteria, as a rule, are demonstrative in the manifestations of their illness. They always emphasize the exceptional severity of their illness, speak of "terrible" suffering, unbearable pain, unique and unusual symptoms. At the same time, they do not carry out their “grave” condition, they do not try to get rid of it. On the contrary, the disease for them is a "desired", a kind of defensive reaction in the current conflict situation (for example, "I am seriously ill, so I can not be dismissed from work"). With unfavorable circumstances for the patient, an increase in the manifestations of the disease is observed. The behavior of the patients becomes demonstrative, the character is increasingly selfish, all interests focus only on themselves and their illness. Hysterical disorders can be short-term or long, sometimes take a wavy character with frequent exacerbations. It all depends on how patients can achieve with the help of their illness, what they want. However, in life it turns out the opposite. Patients do not so much realize their interests as they do damage to themselves. The family is destroyed, you have to leave work, the whole life turns into a continuous illness.
