Ataxia

Ataxia is a disorder (violation) coordination (inaccuracy, nanorazmernoi movements, loss of smoothness, continuity). OK coordination is carried out automatically coordinated activities of a number of formations of the nervous system (the cerebellum, pathways deep muscle and joint sensitivity going on in the composition of the rear pillars of the spinal cord, and the vestibular apparatus). Accordingly affecting different parts of this complex system there are three types of ataxia: cerebellar, sensitive and labyrinth.
Ataxia occurs for a number of diseases.
Acute ataxia may develop in infectious diseases (pneumonia, abdominal and typhus tifa, diphtheria and other). Symptoms of ataxia appear at the height of the infectious process.
Symptoms of ataxia can develop in different cases of intoxication (alcohol, nutritional poisoning, mercury and others).
Treatment of ataxia. Along with treatment of the underlying disease atactic disorders respond well therapeutic gymnastics, designed for training coordination. With Friedreich's ataxia, which is a hereditary disease, further childbearing in a family where there are patients is not recommended. Healthy family members can have children, but should avoid related marriages.

Ataxia (from the Greek. ataxia - the lack of order, disorder) is a disorder of motor skills, expressed in infringement of coordination of movements. The latter are disproportionate and awkward.
For accurate and correct execution of the motor act and to keep the balance at various positions of the body requires the coordinated work of several muscle groups and uniform distribution of tone between the agonists and antagonists. OK this work is performed automatically as a result of coordinated activities of a large number of different structures of the Central nervous system. In addition to the system of voluntary movements, pyramid presents ways, and systems for automatic friendly movements represented extrapyramidal ways, there is another movement system that operates automatically and regulatory coordination,the cerebellum, which is the Central body coordination.
Coordinated work of muscles depends on the proper operation of the Central apparatus and security of centripetal proprioceptive impulsaciu. The impulses that come from the muscles, tendons, joints and ligaments are routed through the side columns of the spinal cord to the cerebellum and back columns of the spinal cord and brain stem to the back Central gyrus and parietal area of a bark of the big hemispheres. Not less important and the signals coming from the inner ear from the semicircular canals of the maze to the vestibular nerve. Thus, there is a powerful centripetal ways that send signals about the position of the head and various parts of the body in space. On this difficult alarm cerebellum is responsible via efferent tracts, ending the cells of the anterior horn of the spinal cord, which sends pulses directly to the muscles. This cerebellar system works closely with the higher nervous activity of man by the two powerful systems that connect the brain cortex with opposite hemispheres, cerebellum.
Clinical manifestations there are ataxia static and locomotor. Static balance is disturbed when standing, with locomotor coordination of the movements of the limbs. In both cases, despite the far-reaching motility disorders, paralysis does not happen. Accordingly affecting different parts of a complex system, regulatory coordination, there are ataxia sensitive, cerebellar and labyrinth.
