Vegetative-vascular dystonia is a type of dystonia. It shares common features with several autonomic dysfunctions, such as orthostatic hypotension and postural orthostatic tachycardia syndrome. These features include orthostatic intolerance and vasovagal response. Vegetative-vascular dystonia also has considerable overlap with other medical diagnoses, including posttraumatic stress disorder, anxiety disorder, major depressive disorder, and somatoform disorder. However, it is not formally recognized in existing ICD-9 and ICD-10 disease classification systems.
The closest analogue is autonomic dysfunction and mitral valve prolapse syndrome.
Characterization of vegetative-vascular dystonia in Western medical literature is limited. However, this disorder has been characterized extensively in Russian medical literature. Until recently, the (Russian) vegetative-vascular dystonia page incorrectly linked to Da Costa's syndrome via Wikidata. However, a thorough description of this dystonia requires complete translation of the Russian page into English and expansion of this English page on the subject.
