Ultraviolet Test in Neurology

An ultraviolet test in neurology is a method for detecting unilateral damage to the autonomic nervous system. It consists of equal and simultaneous exposure to ultraviolet radiation on symmetrical areas of the skin, after which the severity of erythema on them is compared.

The principle of operation of the ultraviolet test is based on the fact that ultraviolet radiation causes the dilation of blood vessels in the skin and an increase in blood flow. This leads to redness of the skin - erythema. With unilateral damage to the autonomic nervous system, erythema will be more pronounced on the affected side than on the healthy side.

An ultraviolet test is used to diagnose autonomic disorders, which can be caused by various diseases, such as neuropathy, migraine, stroke and others. It can also be used to determine the effectiveness of treatment and monitor the patient's condition.

To carry out an ultraviolet test, it is necessary to apply ultraviolet radiation to the skin in symmetrical areas. Then the severity of erythema on both sides is compared. If one side is redder, this indicates the presence of autonomic disorders.

Advantages of ultraviolet testing include its ease of use and availability. However, it is not a universal diagnostic method, and may be less accurate than other methods such as electromyography or magnetic resonance imaging.

Ultraviolet testing is one of the most effective and accurate methods for diagnosing damage to the autonomic nervous system. When conducting an ultraviolet test, infrared radiation of a certain wavelength is applied to the patient's skin, which leads to the appearance of erythema (redness) on the skin. Erythema appears on a certain area of ​​the skin that was previously irradiated with ultraviolet light. The method allows you to determine damage to the symmetry of autonomic innervation.
