[Cerebral circulation (measured by isotopes) and acid-base equilibrium of the cerebrospinal fluid during migraine]. 1976

D Saurugg, and G Schnaberth

In migraine patients a considerable metabolic disturbance characterised by a decrease in bicarbonate and an increase in lactate was demonstrated during the migrainous state. Measurements of the cerebral circulation were taken by means of radioactive isotope and showed a distinct decrease in blood supply to the entire brain during the migraine attack. Following forced hyperventilation during the attack-free interval a pathological reactivity with decreased blood flow was found in the hemisphere which had been indicated as the usual site of the migrainous pain.

UI	MeSH Term	Description	Entries
D006985	Hyperventilation	A pulmonary ventilation rate faster than is metabolically necessary for the exchange of gases. It is the result of an increased frequency of breathing, an increased tidal volume, or a combination of both. It causes an excess intake of oxygen and the blowing off of carbon dioxide.	Hyperventilations
D007773	Lactates	Salts or esters of LACTIC ACID containing the general formula CH3CHOHCOOR.
D008881	Migraine Disorders	A class of disabling primary headache disorders, characterized by recurrent unilateral pulsatile headaches. The two major subtypes are common migraine (without aura) and classic migraine (with aura or neurological symptoms). (International Classification of Headache Disorders, 2nd ed.

D012146	Rest	Freedom from activity.	Rests
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon

D001639	Bicarbonates	Inorganic salts that contain the -HCO3 radical. They are an important factor in determining the pH of the blood and the concentration of bicarbonate ions is regulated by the kidney. Levels in the blood are an index of the alkali reserve or buffering capacity.
