Examination of autonomous (vegetative) nervous system

Adequate functioning of the autonomous or vegetative nervous system is very important for the well-being of every person. The evaluation of its functions is important in the event of different complaints. GK Neiroklīnika performs examinations by using modern equipment that enables conclusions to be drawn on the function of the sympathetic, as well as parasympathetic nervous system.

Duration of the procedure

20-30 minutes.

Preparation

Minor amount of preparation is required.

Sensations

The examination is safe, simple and painless.

Limitations

There are no limitations for the performance of this examination.

Advantages of the method

The examination enables decision making on the functionality of the sympathetic and parasympathetic nervous system.

Results

The examination report is drawn up by a neurologist.

Diagnostic principles

Minor preparation for the examination is required one day prior to the examination in order to ensure precision and quality of diagnosis. The specialists will inform you of the nature of preparations, which may include, for instance, abstaining from the use of coffee, sedatives, etc. The examination will be performed by a nurse. The diagnostic procedure is performed by using a device that makes different types of measurements: blood pressure, heart function in a supine and in vertical position, as well as expiration and inspiration control, etc. Thus, the detection of changes with varying loads and in different states is possible. After the examination, the neurologist shall analyse the results and draw up the examination report.

Symptoms that may bear evidence of autonomous (vegetative) nervous system disorders

  • palpitations;
  • dyspnoea;
  • sweating;
  • blurred vision;
  • blushing or paling;
  • anxiety;
  • fatigue;
  • headaches;
  • instability;
  • vertigo;
  • dry mouth or eyes;
  • hypersalivation;
  • frequent diarrhoea or other gastrointestinal tract disorders;
  • weight loss;
  • abdominal pain;
  • urination and sexual function disorders, which cannot be explained by the presence of another disease.

Most common diseases associated with disorders of autonomous nervous system function

  • diabetes mellitus;
  • liver diseases;
  • autoimmune or oncological diseases;
  • metabolic disorders.

Autonomous or vegetative nervous system

Autonomous or vegetative nervous system is an important part of the central and peripheral nervous system that ensures the function of internal organs in accordance with the variable conditions of the internal and external environment. It regulates human body reactions, by preparing the body for physical loads or stressful situations, mobilising organ systems (elevating the blood pressure, increasing the heart rate and respiration frequency, activating perspiration, etc.). Meanwhile at rest it relaxes the body enabling one to restore energy (the heart rate becomes slower, the blood pressure normalises, etc.). Thus, the autonomous nervous system regulates heart function, blood pressure, breathing, sweating, digestion, pupil reactions, urination/defecation, function of endocrine organs and sexual function.

Autonomous nervous system is divided into the sympathetic and parasympathetic nervous system. It functions autonomously and is not subject to human will, however, its functioning is partially affected by the central nervous system (the brain).
