Chorea is one of the forms of hyperkinesis and is a pathology of the nervous system, which is accompanied by malfunctions in the subcortical nodes of the brain and is expressed by chaotic, aimless and episodic twitching mainly in the legs and hands (less often in the trunk).
This term has a dual application. They also identify independent diseases from this group (such as Huntington's chorea or small chorea), and some syndromes that occur in a variety of pathologies. The name "chorea" is also not accidental: in translation from the Greek language it means a certain kind of dance. The patient during the attack looks really awkward: the fast, steep, uncoordinated and jerky movements of limbs and trunks create the impression of a disorderly, somewhat sweeping and involuntary dance. Therefore, chorea acquired another "historical" name - "The Dance of St. Witt", who came to us from the deep Middle Ages. By the way, many people have heard about this uncommon term, which in no way are involved in neurology. The fact is that St. Witt, who lives in Sicily, was tormented by the Romans in his time as an active propagandist of Christianity. And later the belief spread that every person who will dance before the statue of this Saint on his birthday (June 15) will receive a huge amount of energy and vigor for a minimum of one year. So, on this day, around the statue, superstitious citizens began to crowd around, who for their health did not hesitate to "give out" to ridiculously expressive dances. Hence the roots of the expression "the dance of St. Witt", which in due course was christened chorea, grows.
The causes of chorea may be different, but often they are hereditary factors. There are four varieties of this pathology, which became "hostages" of bad genetics (the so-called primary forms). It's about Huntington's chorea, Lesha-Naikhan's disease, neuroacanthosis and benign hereditary chorea.
Among other provoking factors of chorea, doctors indicate the following reasons:
All varieties of chorea, provoked by any factor in this group, are secondary forms of the disease. In addition, there is another type of chorea - psychogenic (it is a kind of psychogenic motor disorders).
Common signs of chorea
Chorea manifests itself as brief, chaotic and, as it were, accidental bodily movements, especially in the limbs. Sometimes they resemble the fast and perfectly normal movements of a healthy person who is disturbed by something, but they are not part of any adequate planned actions. In other cases, arbitrary shudders with chorea are similar to an uncontrolled and emotional "dance." These jerky jerks can be one- or two-sided, and even with the "participation" of both sides of the trunk they are not synchronized.
Khorea Dance of St. Vitus
Manifestations of chorea vary depending on the form of pathology. Thus, with slightly expressed choreic hyperkinesia, there is a slight motor anxiety, which can be accompanied by inadequate gestures, unexpected fussy movements, certain grimaces, increased emotionality and motor disinhibition. As for the clearly expressed forms of chorea, they usually manifest themselves in the peculiar movements of the "devil on the thread" or loosened up violent "dance". Expressive choreic hyperkinesis distorts not only speech and facial expressions, but even movements when walking. The walk of such a sick person can be described as strange and somewhere "clownish". And patients with an extremely severe form of chorea, in contrast, can not at all perform any movements. They find it difficult to move around because of permanent falls, they are not able to fully serve themselves in everyday life, and therefore they are dependent on close people. Choreic twitching in mimic and oral muscles of the face (including the larynx and tongue) prevent both verbal communication and food intake. Such patients can easily carry a fork with food past the mouth or can not "get" a napkin into the nostrils to blow out a stuffy nose.

Chorea and its treatment
Therapeutic actions depend on the specific type of disease . Thus, with Huntington's chorea, there are effective agents that reduce the activity of dopaminergic brain systems: reserpine, haloperidol, phenothiazine derivatives, and the like. Tranquilizers and neuroleptics also help the patient cope with depression and internal discomfort. With a small chorea, you should go to a hospital. In addition to bed rest, antibiotics (peni- and novocellin), glucocorticoid hormones, salicylates, calcium preparations, cardiac drugs, multivitamins are prescribed. From fizioprotsedur actual conifer baths, electrosleep, galvanic collar for Shcherbak with calcium chloride.
