[Rheoencephalographic signs of inadequate blood supply to the brain in early cerebrovascular insufficiency].

Using the method of functional rheoencephalography the author examined 450 patients with initial signs of inadequate blood supply of the brain. Characteristics of the rheoencephalographic signs of the blood supply inadequacy are given and their importance for early diagnosing of various forms of cerebrovascular pathology, revealing latent forms of the latter, and determining collateral circulation paths, compensatory potentialities, and indications for angiographic examinations are discussed.
