Secondary encephalitis

Secondary encephalitis often develop in children against the background of acute or chronic infections, less frequently in adults.
Encephalitis varicella is rare. Neurological symptoms are found more often on 3-8 and day of the illness. On the background of a moderate temperature increase appear convulsions, violent movement, paralysis, disorders of the coordination. May be damaged optic nerves, which leads to violation of view; meningeal symptoms are rare. For favourable residual effects in the form of paralysis, epileptiform seizures are very rare.
Flu-like encephalitis occurs in periods of epidemics in toxic forms of influenza. Encephalitis is developing as in the acute period, and during the extinction of influenza infection. The disease occurs in the form of encephalitis or meningoencephalitis. Against the background of increasing temperature with chills, headache, vomiting, photophobia. In hemorrhagic forms observed agitation, alternating with oglushennosti and coma. Focal brain lesions appear violation of coordination, paralysis, disorders of speech, reveals meningeal syndrome. In the cerebrospinal fluid is determined by the increase in the number of lymphocytes or significant blood high in protein. Hemorrhagic form of the influenza encephalitis gives the mortality rate to 70% and expressed residual effects in the form of paralysis and paresis. To differentiate it from a subarachnoid hemorrhage.
Measles encephalitis occurs in children with measles, usually at the end of the period rash - on 5-8 and day of the illness. The rising temperature, drowsiness, coma with respiratory disorders. Possibly drastic action, delirium, seizures, tonic convulsions followed by the development of paralysis of the limbs, disorders of sensitivity and function of the sphincter, reduced hearing and vision, speech disturbance. Can be meningeal syndrome. In the spinal fluid - the increase in the number of cells to 200-300, protein - up to 0.6-0.8% respectively.
Malaria encephalitis develops during the febrile attack or outside of it. Characterized by periodical increase symptoms in connection with the intensification of malaria. Malaria encephalitis is accompanied by fever, headache, vomiting, acute become paralysed limbs on one side of the body. Often affected the trigeminal nerve, which is manifested by pain in the face. More rarely there is loss of hearing, oculomotor nerves: worsens the hearing, you receive the vision and other children often forced movements, seizures epileptiformnye. In tropical malaria may develop a coma with a high temperature, lack of response to their environment, sharp muscular hypotonia. The icteric skin, facial features sharpened, liver and spleen enlarged in the blood is determined malaria plasmodia.
Rheumatic encephalitis is one of the manifestations of rheumatic affection of nervous system. Ill more often than children aged 6-15 years. Brain damage often develops on the background of a sore throat, joint injury, rheumatic Encomienda. The disease begins subacute, with the emergence of violent movements of limbs, facial muscles and body language - small chorea (see). Broken accuracy of movements, in connection with which children become untidy, unkempt, positivity when walking. Change dramatically handwriting, see gramatycznie, artsy movement, which initially are the antics of the child. Strengthening violent movements leads to the fact that the child becomes self is, to move, to dress. In connection with the hyperkinesia language and muscles of the pharynx is broken it, you receive podergivani with the food. Muscle tone is sharply reduced, children become irritable, cranky.
In other forms of rheumatic encephalitis, other than minor horei may be stereotypical hyperkinesia distal extremities (tapping his brush, the jerking stops and others). The tone of muscles remains normal or dystonia. These hyperkinesia have considerable resistance. In some cases, there may be a phenomenon of torsion dystonia, myoclonic hyperkinesia; children often diencephalic syndrome.
Encephalitis if rubella is rare, develops on 3-8-and the day after rash. There is a high temperature, headache, vomiting, can be a limb paresis, convulsions. During favorable.
Most primary and secondary encephalitis occurs with picture meningoencephalitis (tick, and other flu-like), when there are inflammatory changes of the brain and its meninges. When encephalitis often have a mental disorder. Acute encephalitis in connection with a high fever and swelling of the brain are observed delusions, hallucinations, agitation. Especially pronounced mental disorders are at a lethargic encephalitis. In the chronic phase lethargic encephalitis occur mental disorders in the form of inertia, dullness, dwelling on some details, slowness of thought processes, memory disorders.
