[Transcranial dopplerography and variational pulsimetry in the diagnosis of cerebral angiodystonias in children].
The hypoxemia-hypercapnia test with closed-space breathing has been performed in 71 children aged 9-15. The examinees comprised three groups: healthy controls (n = 12), patients with latent cerebral angiodystonia (n = 9), patients with clinical cerebral angiodystonia (n = 50). The patients could hardly tolerate closed-space breathing. They complained of head aches, dizziness, suffered from vegetative stigmas, neurological deficiency. In subclinical and apparent disease vegetative dysadaptation predominated in the parasympathetic and dysregulatory forms. The load-provoked increase in the linear blood flow rate and a decrease in the resistance index appeared more pronounced in the controls. This evidences reduced adaptive potential of brain autoregulation in patients with cerebral angiodystonia.
