It is based on the formulation of a differential diagnosis, the essence of which is the need to differentiate the signs of similar diseases and syndromes. So, first of all it is important to differentiate the disturbances in the activity of the nervous system from violations of activity and irritability of the muscle fiber. Also at the heart of the pathology may lie the usual decrease in muscle tone. Then it is necessary to differentiate the pathology of nervous and muscular conduction from the characteristic disorders of the brain and its individual parts. It is also important to differentiate this syndrome from other diseases that have similar manifestations.
This pathology is associated with impaired electrical activity of the brain, in which there is a disturbance of circulatory processes, and, first of all, circulation of blood in the brain. The essence of the processes is roughly the same: first, the impulse is perceived by the receptors, then it is transmitted to the brain via the afferent nerve fibers. If the development of encephalopathy occurs, there is a disruption in the activity of the brain departments responsible for processing the information received, as well as the circulatory processes. As a result, an attenuated, or distorted, nerve impulse enters the efferent pathways, which leads to a violation of the muscle tone.
It is a genetic pathology, which is caused by genetic disorders of the structure and function of muscles, as well as their tone. A characteristic feature of myasthenia gravis is the progressive decrease in muscle tone, which is based on the degeneration of muscle fibers, the reduction of reserve nutrients in the cell and tissues. It is accompanied not only by a decrease in tone, but also by pain syndrome, seizures and spasms.
At the heart of pathogenesis is a violation of the muscle tone and normal functional state of the fascia (connective tissue envelope surrounding the muscle). Most often, myofascial syndrome is a consequence of a trauma or inflammatory process. Quite often it occurs in athletes, whose muscles are subjected to increased physical exertion. Often observed with sudden movements, overload of the muscular system.
Spondylarthrosis means a degenerative-dystrophic disorder of a polyethological nature. At the heart of the pathogenesis of spondylarthrosis is the primary lesion of the articular cartilage. Subsequently, the subchondral and metaphyseal layers of the bone are involved in the pathological process. Further progression of the disease is accompanied by damage to the synovial membrane, ligaments, muscles. In this case, there are clearly expressed signs of osteophyte formation, and pain syndrome appears, movements in the joint are sharply limited. It ends with loss of mobility of the joint.
It is characterized by dystrophic processes in the muscular system, in which there is a decrease in reserve nutrients in the muscle tissue, which entails a violation of trophism. Accordingly, the muscle does not receive the necessary amount of nutrients, oxygen, as well as delayed metabolic products and carbon dioxide. The intoxication of muscle tissue is increasing, the supplies of nutrients and oxygen continue to be depleted. With muscular dystrophy , the degradation of the basic structural elements of the muscle fiber is gradually occurring, the muscle is destroyed, and its functional activity is reduced. The process is usually irreversible.
