Brain activations in the premonitory phase of nitroglycerin-triggered migraine attacks.
Our aim was identify brain areas involved in the premonitory phase of migraine using functional neuroimaging. To this end, we performed positron emission tomography scans with H2(15)O to measure cerebral blood flow as a marker of neuronal activity. We conducted positron emission tomography scans at baseline, in the premonitory phase without pain and during migraine headache in eight patients. W...
متن کاملOccipital activation in glyceryl trinitrate induced migraine with visual aura.
A case of migraine is presented with visual aura triggered on two separate occasions by glyceryl trinitrate (GTN). Positron emission tomography was carried out during the second triggering session. Activation in the primary visual area of the occipital cortex was demonstrated during the aura. This is the first published case of migraine aura triggered reproducibly by GTN.
متن کاملA PET study exploring the laterality of brainstem activation in migraine using glyceryl trinitrate.
Migraine is a common disabling condition likely to be associated with dysfunction of brain pathways involved in pain and other sensory modalities. A cardinal, indeed signature, feature of the disorder that led to its name is that the pain may be lateralized. H(2)15O-labelled PET was used to study 24 migraineurs and eight healthy controls. The migraineurs were divided into three groups according...
متن کاملThe prevalence of premonitory symptoms in migraine: a questionnaire study in 461 patients.
Migraine attacks are often preceded by premonitory symptoms. Prevalence rates of migraine patients reporting one or more premonitory symptoms show considerable variability and rates range between 12% and 79%. Sources of variability might be differences in study population or research design. Using a questionnaire, we retrospectively studied the prevalence of 12 predefined premonitory symptoms i...
متن کاملComparison with glyceryl trinitrate
The coronary haemodynamic effects of nifedipine and glyceryl trinitrate were compared in 22 patients undergoing investigations for suspected coronary artery disease. Myocardial blood flow was estimated by the coronary sinus thermodilution technique. In sinus rhythm nifedipine increased mean coronary sinus flow from 135 ml/min to 152 m/min, and reduced arterio-coronary sinus oxygen difference fr...
