Reasons for


The most commonly diagnosed viral disease in the spring and autumn periods of the year.And this is due to the activity of ticks - it is these insects, the inhabitants of forests and fields, that carry the disease.Note: in different regions of Russia the incidence of tick-borne encephalitis is different. Encephalitis Tick encephalitis refers to the primary type of disease - the effect of the virus is directly on the substance of the brain or the spinal cord, no concomitant pathologies of infectious, inflammatory etiology are not diagnosed.2-2_profimedia_0017629549

Symptoms of tick encephalitis

When infected with tick-borne encephalitis virus, the symptoms of the pathology manifest themselves almost immediately - if, for example, the bite was done in the morning, then by the evening the patient will show signs of the strongest intoxication of the body:

  • nausea and severe vomiting -It occurs irrespective of how long ago and how many people took food;
  • sharp rise in temperature to critical levels - no antipyretic drugs do not bring relief;
  • headaches are intense, accompanied by pulsation and a feeling of squeezing the skull;
  • skin of face and neck blushes.

After a short time, other signs of encephalitis develop:

  • lowering of arterial pressure;
  • signs of inflammation at the site of a bite( swelling, redness, pain during palpation);
  • cardiac rhythm disturbance - arrhythmia, bradycardia, is expressed in dyspnea and chest pains;
  • rigidity of the occipital muscles - they are extremely strained, the patient can not keep his head straight, it is thrown back;
  • photophobia.

Important: if tick-borne encephalitis was detected at the very beginning of its development, then the forecast doctors give always favorable.Otherwise, a person either dies or becomes disabled. Symptomatology may vary depending on the form in which the disease under consideration develops.The initial period is characterized by the presence of neurological disorders( dizziness, disturbance of the psycho-emotional background, etc.), can result in complete recovery without complications and consequences or the death of the patient.The next period can be accompanied by epileptic attacks, paresis and paralysis, numbness of the skin of the face and neck, increase in body temperature to 39-40 degrees. The doctor observes the degree of difference in neurological disorders and determines the type of tick-borne encephalitis:

  1. Febrile - the patient shows signs of general intoxication of the body, recovery occurs relatively quickly.
  2. Meningeal - proceeds with a fever and all signs of a meningococcal infection, even in a cerebrospinal fluid there is a meningococcal element and a protein.The patient often fixes mental disorders of reversible type - delirium, hallucinations, excessive excitement.The disease in this form has a favorable prognosis, but chronic paresis of facial muscles can develop.
  3. Meningoencephalitic - differs in violation of the mimic picture( eyelids drop, corners of the eyes, face distorted), loss of sonority of voice, disturbance of the speech device.For the meningoencephalitic type of the disease under consideration, the wave current of hyperthermia is characteristic( increase in body temperature).The first wave lasts 2 weeks and is accompanied only by intoxication symptoms, the second comes 2-3 days after the end of the first, accompanied by symptoms of meningitis and lasts 3 weeks.The forecast is favorable.
  4. Poliomyelitis - within the first 2 days patients complain only of fatigue and muscle pain.Then, impaired motor functions develop, regular muscle twitching, paresis in the shoulder and neck regions of the spine, and dangling of the head on the chest.This kind of tick-borne encephalitis has a variety of predictions, because 2-3 weeks after recovery the patient becomes atrophy of the affected muscles - it can be reversible( the patient completely recovers) and irreversible( disability threatens).
  5. Polyradiculoneuritis - viral infection affects the roots of peripheral and frontal nerves, limbs become insensitive to external stimuli.

Diagnosis of tick-borne encephalitis

Preliminary diagnosis is made by the doctor at a primary examination of the patient - complaints of headache, fever, convulsions in muscle tissues,Patient in the forest / park area a few days before the onset of symptoms confirm the suspicion of the onset of the disease in question. But no expert can diagnose without additional examinations:

  • computed tomography of the brain - allows the doctor to see the inflammatory process in the brain, to assess its prevalence and severity;
  • fence for laboratory testing of cerebrospinal fluid( cerebrospinal fluid) - reveals the presence of protein in it, high content of leukocytes;
  • biochemical blood test.

Treatment methods

Big If tick-borne encephalitis has been identified at an early stage of development, then antiancephalitic immunoglobulin therapy will be effective.For successful recovery, the patient is administered inactivated vaccine and ribonucleic acid.Please note: similar vaccination can be carried out and for preventive purposes - it helps to avoid infection with the considered viral disease and reduce intoxication manifestations of the inflammatory process.It is recommended to be vaccinated in the spring and autumn periods - the peak of patients' appeals for the development of typical symptoms of tick-borne encephalitis.

General principles of therapeutic measures

A patient with diagnosed tick-borne encephalitis must comply with strict bed rest during the acute period of the disease course - this greatly facilitates the patient's condition. In addition, doctors can prescribe:

  • antibacterial drugs( antibiotics) - especially their appointment in the development of the meningeal form of the disease in question;
  • antiviral agents;
  • vitamins B and C;
  • immunostimulating agents.

It is important to carry out symptomatic therapy in a timely manner - for example, when the body temperature is elevated, antipyretic agents should be prescribed, if there is an intense pain syndrome, non-steroidal anti-inflammatory drugs or analgesics.Only after 3 weeks, and in case of complete stabilization of the patient's condition, an extract is possible.The rehabilitation period is very long - the patient should visit the therapist once a month and once a month - the neurologist.Mud therapy, sanatorium treatment are useful.

Traditional medicine

A tick, which has already dug into the skin and is absorbed by the blood of a person, is easy to detect( especially the female), but it is almost impossible to pull it out yourself.

All the folk methods of getting rid of the stinging tick( dripping vegetable oil, wrapping it with a thread) are absolutely useless - the infection with tick-borne encephalitis occurs at the moment of biting the insects by human skin.

Lyme_19701_7 Important: folk methods of treatment of the disease in question are aimed at strengthening the body, getting rid of headaches, they are appropriate to use in the recovery phase.It is strictly forbidden to take any medical measures when developing symptoms of tick-borne encephalitis without consulting a doctor - this can lead to rapid development of the disease and death. For the fastest passage of the recovery period it is recommended to use the following tools from the category of traditional medicine:
