Cerebellar and cerebral autoregulation in migraine.
BACKGROUND AND PURPOSE Silent ischemic brain lesions frequently occur in migraine with aura and are most often located in cerebellar border zones. This may imply an impairment of cerebellar blood flow autoregulation. This study investigated the characteristics of interictal cerebellar autoregulation in migraine with and without aura. METHODS Thirty-four patients (n=17, migraine without aura; ...
متن کاملCompromised Dynamic Cerebral Autoregulation in Patients with a Right-to-Left Shunt: A Potential Mechanism of Migraine and Cryptogenic Stroke
BACKGROUND AND PURPOSE The relationship between right-to-left shunts (RLS) and migraine and cryptogenic stroke is not well understood. In this study, we investigated whether RLS are associated with impairment of dynamic cerebral autoregulation (dCA), which may play a role in migraine and cryptogenic stroke. METHODS Sixty-six migraineurs were enrolled in the study, including 36 non-RLS patient...
متن کاملCerebral Autoregulation in Stroke
Background and Purpose—Cerebral autoregulation may become impaired after stroke. To provide a review of the nature and extent of any autoregulation impairment after stroke and its course over time, a technique allowing repeated bedside measurements with good temporal resolution is required. Transcranial Doppler (TCD) in combination with continuous blood pressure measurements allows noninvasive ...

reactions. Intermediary metabolism, for example, is run by enzymatic machines that are revved up and down by allosteric responses to the binding of small molecules. And in bacteria we know of one set of genes that is not regulated by recruitment: the inactive promoters bear a special form of tightly-bound RNA polymerase, and the activator uses energy in the form of ATP to turn on transcription....
متن کاملCerebral autoregulation in man.
Cerebral Auwregulalion in Man • Autoregulation was tested by regional blood flow (rCBF) and cardiohemodynamic measurements before and after induced systemic arterial hypertension in 16 patients with varying neurological disorders. Hypertension was induced by increasing the arterial blood pressure by an intravenous infusion of Aramine. Seven (Group 1) of the patients had a mean increase in mean ...
