[Role of the vascular component in the pathogenesis of headaches in neurotic patients].

The authors studied the volume velocity of extracranial blood flow by an original method of venous occlusional cranial pletysmography in 40 individuals with headaches of stress and in 30 examinees without headaches in conditions of calmness and in stress influences (cold test, terminal desympathization, counting by mind and a nitroglycerine test). Different types of reactivity of the extracranial vessels in 20 patients with headaches of stress and in 20 examiness of the control group were studied. It was established that the medium figures of the extracranial blood flow in patients with headaches of stress do not differ from the corresponding figures of the normals in the control group. Some stress influences (counting in mind and nitroglycerine tests) in patients with headaches of stress call forth a more frequent increase of the blood flow than in the control group of normals.
