The effect of voluntary hyperventilation was assessed in 22 cluster headache patients (8 in a cluster period and 14 in a remission) and 19 healthy individuals. Using an ear oximeter and a capnograph with a nasal probe, the oxygen saturation (SaO2) and the end-tidal CO2 were monitored continuously.
The comparison of two groups of migrainous patients with or without hyperventilation syndrome (HS) provided the conclusions that HS provokes more severe migrainous attacks and psychovegetative symptoms in migrainous cephalalgia (MC). The findings also support the existence of stem structure
Twenty-eight cluster headache patients were examined either in remission (n = 10), in the interparoxysmal period ("cluster phase") (n = 12), or during spontaneously occurring (n = 7), or nitroglycerin provoked (n = 7) attacks. Fourteen healthy controls participated in the study. Oxygen saturation
Using the method of rheoencephalography 182 children aged 8 to 16 years and suffering from functional headaches were examined. With regard to the clinical criteria they were divided into two groups: patients with migraine, and those with vasomotor headache. The control group consisted of 345
To study the pathophysiological mechanisms of hyperventilation-induced EEG showing, i.e., the so-called 'buildup' phenomenon, changes in regional cerebral blood flow (rCBF) were investigated before and during the phenomenon in a 16-year-old woman with headache, thought to be of neurotic origin, by
The author describes three observations characterized by the following similar features: 1. Children, between 2 and 9 years, suffering from attacks of sterotyped headaches. 2. EEG with bursts of high- voltage paroxysmal discharges, mainly during hyperventilation. 3. Efficiency of antiepileptic drugs
This basic review is intended to summarize the current knowledge of methemoglobinemia as an important cause of secondary headache with the hope of generating a growing interest in studying this phenomenon.We describe the pathological underpinnings of Hyperventilation (HV) is an important activating procedure in clinical EEG. Paroxysmal HV slowing is associated with hypoglycemia and is common in children. Paroxysmal slowing in adults is sometimes interpreted as indicating cerebral instability or paroxysmal tendencies. We investigated the clinical
OBJECTIVE
To study the frequency and characteristics of headache which is in the past history (HPH) of patients with cervical artery dissection (CeAD) and evaluate with the help of EEG and visual evoked potentials (VEP) the role of central mechanisms in its development.
METHODS
Two hundred and
Ten cluster headache patients and 10 healthy controls were subjected to electrocardiographic and pupillometric procedures in a search for cardiac and pupillary sympathergic asymmetry. Sympathergic stimulation was provoked by hyperventilation and by instilling tyramine into both eyes. In the control
In cluster headache an adrenergic dysfunction of the pupillary sympathetic system can be demonstrated even during pain-free periods by instillation of tyramine in the conjunctival sac. In this study 10 patients with typical cluster headache syndrome exhibited a positive tyramine conjunctival test
Hyperventilation syndrome (HVS) often occurs under stressful conditions, and has been reported during or after anesthesia and operation. HVS, characterized by multiple somatic symptoms and electrolyte imbalances induced by inappropriate hyperventilation, should be managed as an emergency. We report
A single-breath CO2 test was carried out in cluster headache patients both during bout and remission, and in matched healthy individuals (n = 10 for each group) to assess peripheral chemosensitivity. The test subjects inhaled one tidal breath of 13% CO2 in air. The response was expressed as the
OBJECTIVE
To show that demand valve oxygen is an effective acute treatment for cluster headache and to compare this oxygen delivery technique with standard cluster headache therapy of continuous flow oxygen.
METHODS
Single-center, open-label, two-period, two-treatment crossover design, pilot study
35 patients with vegetocirculatory dystonia and hyperventilation syndrome, but without the signs of organic lesion of nervous system were treated. The complex treatment included the breathing exercises with feedback mechanisms, the correction of psychovegetative and neurovascular disturbances, the
