"Acephalgic migraine"

OBJECTIVE: Migraine with aura is considered common during the pediatric age and in some cases it could be hard to distinguish migraine from mimicking conditions. We would like to emphasize the role of susceptibility-weighted imaging (SWI) in pediatric migraine patients with aura. METHODS: We retrospectively reviewed the clinical and SWI findings of two pediatric migraine patients with aura. RESULTS: Initial SWI of two pediatric migraine patients with aura demonstrated venous conspicuity in the left cerebral hemisphere and follow-up SWI of them showed normal findings with symmetrical venous vasculature...

A hypothesis is presented on the mechanism of acute intracranial occlusion. The hypothesis is that a chronic dysfunctional response to stress can include migraine, hypertension and systemic platelet activation (a hypercoagulable state). Stress is defined as the perception of excessive threats or demands. Migraine, hypertension, and platelet activation constitute a physiological triad that exists as a distinct entity and can undergo sudden provoked or unprovoked worsening, causing acute stroke. The hypertension and headache may not be apparent in every stroke, much as headache is absent in acephalgic migraine...

Transient visual and neurological episodes are relatively common and can occur for the first time in middle and old age. In many cases these transient events are migraine auras. An aura is a transient, stereotypical, visual or neurological episode usually lasting 4 to 60 minutes in duration. Migraine is usually, but not always, associated with headache and can be accompanied by systemic and autonomic symptoms. Diagnosis is dependent on International Headache Society criteria. The pathophysiology is believed to involve neurovascular mechanisms...

Migraine equivalents of infancy, childhood, and adolescence are recognized periodic, paroxysmal syndromes without associated headache that are thought to be migrainous in etiology. Five such equivalents are presently recognized. Their clinical features and relative frequency in ambulatory pediatric neurology practice have not been well documented. Utilizing a comprehensive, standardized computer database, the occurrence of these migraine equivalents in a single pediatric neurology practice together with their observed clinical features were documented over an 8-year period...

This is a qualitative and chronological analysis of ictal and postictal symptoms, frequency of seizures, family history, response to treatment, and prognosis in nine patients with idiopathic occipital epilepsy and visual seizures. Ictal elementary visual hallucinations are stereotyped for each patient, usually lasting for seconds. They consist of mainly multiple, bright coloured, small circular spots, circles, or balls. Mostly, they appear in a temporal hemifield often moving contralaterally or in the centre where they may be flashing...

Anterior ischemic optic neuropathy is a well-recognized clinical syndrome that has been described in patients after an episode of migraine with visual aura (classic migraine) and, less commonly, after an episode of visual aura without headache (acephalgic migraine). Little emphasis, however, has been placed on migraine-associated retrobulbar or posterior ischemic optic neuropathy. We report two cases of visual loss presumed to be due to posterior ischemic optic neuropathy that occurred in the setting of otherwise typical migraine episodes...

Migraine aura without headache (acephalgic migraines) is a recognized subset of migrainous phenomena in the adult population. No reports of its prevalence or characteristics in a series of children exists. Using diagnostic criteria for migraine aura without headache established by the International Headache Society, a retrospective review of a computerized database of all patients referred over a 4-year period (July 1991 to June 1995 inclusive) to a single university-based pediatric neurologist was performed...

Sixty-one patients with acephalgic migraine have been seen and thoroughly evaluated at the USAF School of Aerospace Medicine over the past 15 years. Patient age ranged in years from 21 to 61, with the number of spells varying between 1 and 100 and lasting from 15 seconds to 3 hours. These phenomena were present for 2 weeks to 25 years. Ocular involvement was represented by scintillation, transient hemianopia, bilateral central scotomata, classic amaurosis fugax, diplopia, altitudinal field loss, tunnel vision; temporal crescent involvement, and several patients who developed a transient central scotoma in one eye with alterations in color perception...

The diagnosis of acephalgic migraine is complicated by the fact that other neurological conditions such as transient ischaemic attacks, demyelinating disease, simple partial epilepsy, and even glaucoma, can present with similar symptoms. Using both flash and pattern stimulation, visual evoked potentials (VEPs) were examined as a means of differentiating between acephalgic migraine, migraine with aura, migraine without aura, demyelinating disease and a control group. This study demonstrated that by analysing the amplitude of the background fast activity in the flash and pattern VEP, acephalgic migraine can be differentiated from demyelinating disease, migraine with aura, migraine without aura and absolute controls...
