Rheoencephalography (bioimpedance plethysmography, cerebral rheography) is a method of diagnosis of brain blood supply.The procedure is performed using a special machine called rheography.For

cerebral rheography using metal electrodes, which by means of rubber bands are fastened to the head.To enhance the sensitivity to disc electrodes applied a special grease introducer.Portions of the scalp, which are attached to the electrode plates, previously degreased with alcohol.Then, through the electrodes passes a small current, which plays a major role in registering the state of cerebral vessels.

Rheoencephalography is a non-invasive method for studying cerebral vessels.The physical basis of this procedure - the difference between the electrical conductivity of the body tissues and blood.

Cerebral rheography gives you the opportunity to get objective information about the magnitude of pulse volume, peripheral vascular resistance, as well as th

e reactivity, flexibility and tone of cerebral vessels.

main advantages of the brain are rheoencephalography:

  • simplicity of the method.
  • Ability to conduct research over a long period of time.
  • Implementation of procedures in all conditions.
  • Getting separate health information venous and arterial systems of the brain.
  • Getting information about intracerebral vessels of different diameters.

When appointed?

Make rheoencephalography cerebrovascular medical experts recommend the following states:

  • frequent headache.
  • Vertigo.
  • hearing and visual impairment of unknown origin.
  • Hypertensive heart disease.
  • cognitive impairment, sleep and memory.
  • weather-sensitive (reaction to changes in the weather).
  • Stroke.
  • craniocerebral trauma.
  • Violation of cerebral blood flow.
  • cervical-cranial syndrome.
  • neck injury.
  • concussion and brain contusion.
  • lability intracranial pressure.
  • vertebrobasilar insufficiency.
  • Parkinson's disease.
  • Encephalopathy.
  • pituitary adenoma.
  • vascular dystonia.

Doctors prescribe brain rheoencephalography in cases when it is necessary to find the viscosity of blood, if you want to determine the speed of blood flow, with periodic inspections, for the prevention of, and if from time to time there is a strange noise in the ears.Rheoencephalography recommended for persons who have a predisposition to epilepsy.

How to prepare?

Any diagnostic procedure requires training and rheoencephalography vessels of the brain is no exception.

result will be more reliable if the patient is on the eve of a good night's sleep.On the morning before the rheoencephalography doctors are advised to refrain from smoking and drinking strong tea and coffee.Sometimes (by a doctor) a few days before the examination the patient should stop taking medications that affect the vascular tone.In most cases, this procedure is carried out during therapy.

Immediately before the test in 10-15 minutes, doctors recommend rest, sitting in the ventilated room.

patient, it is desirable to take a napkin or handkerchief, which will be useful to him after the examination (to wipe introducer grease).The fairer sex, who have long hair, must have a gum and bobby pins.
