Practical Neurology – The Clinical Features of Migraine With and Without Aura


Practical Neurology - The Clinical Features of Migraine With and Without Aura

Visual snow has often been considered a form of persistent migraine aura. I know how intense and real these health related fears can be, but they are NOT REAL. Not even 50 percent. I thought EVERYONE HAD TO DEAL WITH THIS 24/7!! And that that something might be “visual snow” or “static”. I guess we have to live with it.. Tinnitus, ringing in the ear, the annoying constant noise in the head.

But “there’s no lyme disease around here”!! I, too, had my eyes checked and they were fine. When I was a bit older I fancied in my imagination that it was the subatomic makeup of everything that I was seeing, haha. Of course, I used to like to look at sky and cloud, but now it is not as fun, but not that bad either. When more than one aura symptom occurred, they occurred in succession in 96 percent and simultaneously in four percent of patients. In more than half cases it manifested as simple visual phenomenons (spots, dots, frills, lines). The effect of silence on tinnitus perception.

I really appreciate the Wikipedia article as I now have a name for it. the article then asked me to repeat in my head STOP IT!!!, everytime i found myself thinking like that……this had a massive effect on my outlook and i began to think less and less negative thoughts, i also noticed other people around me thinking negativly and made sure not to let it effect me. I really believe this is what brought it on – that the virus was already hanging out in my body, but the stress made everything haywire and blammo! This is inflammation of the optic nerve caused by multiple sclerosis, or MS. I feel as though my vision will just go in a split second and when i hear loud noises with my eye shut i see bright flashes, i have headaches every day now but no one seems to be taken it seriously. I’m not sure what it is with me and green lights! Less common and rare visual auras include corona phenomena, palinopsia,20 metamorphopsia, macropsia, micropsia, telescopic vision, teleopsia, mosaic vision, and multiple images.

When she attempted to rise, she was weak and unsteady. It prevented reading. Visual aura has been reported as lasting more than one hour in 6-10 percent of patients.21 Other aura symptoms can also last more than one hour as follows: somatosensory aura in 14-27 percent and aphasic aura in 17-60 percent of patients. Hmmm…. The first quarter starts in a few days, and I’m beginning to get worried that my symptoms aren’t from migraines anymore, which is why I stumbled upon this place. So I remember at that point I’d become really sensitive to light, I had the most painful headache I’d ever experience, and I just wanted to lie in a dark room ’cause the light was killing me… A true motor aura is rare, but sensory ataxia or a heavy feeling is often misinterpreted as weakness.

Patients often report a speech disturbance when the spreading paresthesias reach the face or tongue. As a result, patients with ear disorders may be unable to hear sounds properly, or they may feel dizzy. Last month, I developed an itchy scalp and itching tried without success OTC medications. Headache: The Journal of Head and Face Pain 54 (6): 957 966. I really hope this research leads to reasonable treatment options. However, in a prospective study of 861 attacks of migraine with aura from 201 patients, during the aura phase, 73 percent of attacks were associated with headaches; with 54 percent of the headaches fulfilling migraine criteria during the first 15 minutes within the onset of aura.23 Aura follows headache in about 3-8 percent of cases.17 The headache may be contralateral to the side of the visual aura, ipsilateral in up to 62 percent of patients for some attacks,18 or bilateral. So unlike symptoms due to cerebral ischemia, migraine visual or sensory auras typically have a slow spreading quality where symptoms slowly spread across the visual field or body part followed by a gradual return to normal function in the areas first affected after 20 to 60 minutes.24 Cerebral ischemic events typically have a sudden onset with an equal distribution in the relevant vascular territory although the affected area can expand step-wise if blood flow drops in additional vessels.25 The progression in partial seizures is typically much more rapid.

I read online, and found that tinnitus take magnesium as a suggestion. As noted, when more than one aura type occurs, the auras almost always are reported asoccurring one after the other, in contrast to cerebral ischemia where multiple neurological symptoms typically occur at the same time. Finally, migraine aura often begins with positive phenomena such as shimmering lights, zigzags in the vision, or tingling and then followed in minutes by negative symptoms such as scotoma, numbness, or loss of sensation which can also occur during seizures but with a typically faster progression of symptoms. This progression from positive to negative symptoms is not typical of cerebral ischemia. Fisher reported new onset “late life migrainous accompaniments” in 85 patients ages 40 to 73 years with episodes resembling transient ischemic attacks26 similar to the 120 patients he had previously described.27 Most had visual symptoms occurring alone (44/205) or combined with other aura symptoms. Headache was associated with the episodes in 40 percent of cases. In the Framingham study, visual migrainous symptoms were reported by 1.23 percent of subjects (1.33 percent of women and 1.08 percent of men) with onset after age 50 years in 77 percent with the following characteristics: stereotyped in 65 percent; never accompanied by headaches in 58 percent; the number of episodes ranging from 1 to 500 with 10 or more in 69 percent of subjects; and lasting 15-60 minutes in 50 percent.28 In a study of 1000 patients presenting for a comprehensive eye examination in Alabama,29 6.5 percent reported visual symptoms consistent with migraine aura without headache, 8.6 percent females and 2.9 percent males with risk factors including female gender, a history of migraine headaches, and a history of childhood motion sickness.

For example, if you have a heart murmur, you may hear a whooshing sound with every heartbeat; your clinician can also hear that sound through a stethoscope. Aura symptoms were mostly visual. The aura duration was similar in both groups with duration in those with late onset aura as follows: 60 minutes, 13 percent. As this fluid builds up, it causes the membranous labyrinth, which houses the nerve endings in the inner ear for both hearing and balance, to become swollen like an overinflated water balloon. If your bite is not aligned properly, the nerve can cause tinnitus and earache. Alice in Wonderland Syndrome, a term coined by Todd in 1955,31 is a rare migraine aura usually where patients experience distortion in body image characterized by enlargement, diminution, or distortion of part of or the whole body, which they know is not real. Lyme disease, caused by Borrelia burgdorferi, is the No.

The cause may be migrainous ischemia of the nondominant posterior parietal lobule. Other causes include medications (topiramate,32 cough syrup with dihydrocodein phosphate and dl-methylephredrine hydrochloride), Epstein-Barr virus and other infections,33 depression, seizures and a right medial temporal lobe stroke. Persistent visual aura Rarely, migraineurs may have persistent visual aura with some 35 cases reported.34,35 This aura usually consists of simple, unformed hallucinations in the entire visual field of both eyes, including innumerable dots, television static, clouds, heat waves, flashing or flickering lights, lines of ants, a rainlike or snowlike pattern, squiggles, bubbles, and grainy vision. A strong cup of coffee can send me into a spin in a matter of minutes. ICHD, 3rd edition describes persistent aura without infarction as aura symptoms persisting for one week or more without evidence of infarction on neuroimaging. Bfep is actually a normal phenomenon, however those who suffer from visual snow tend to have bfep more often and in scenarios which others don’t usually see it. In all groups, almost all of the people with visual snow had a variety of additional visual symptoms (palinopsia, enhanced entopic phenomena, photophobia, and impaired night vision).

The authors suggest that visual snow is a unique visual disturbance clinically distinct from migraine aura without an effective treatment. Table 2 provides the ICHD, 3rd edition, criteria for migraine with brainstem aura which was formerly termed basilar-type migraine which is now not used because involvement of the basilar artery is unlikely. Migraine with brainstem aura is a rare disorder that usually occurs from ages 7-20 years and rarely presents in patients older than 50 years.37 In one study, the following aura symptoms were reported: vertigo, 61 percent; dysarthria, 53 percent; tinnitus, 45 percent; diplopia, 45 percent; bilateral visual symptoms, 40 percent; bilateral paresthesias, 24 percent; decreased level of consciousness, 24 percent, and hypacusis, 21 percent. Visual symptoms, which usually take the form of blurred vision, shimmering colored lights accompanied by blank spots in the visual field, scintillating scotoma, and graying of vision, may start in one visual field and then spread to become bilateral. The median duration of aura was 60 minutes (range of 2 minutes to 72 hours) with two or more aura symptoms always occurring. Retinal migraine is rare with a mean age at onset of 25 years presenting with fully reversible monocular positive and/or negative visual phenomena lasting less than one hour (Table 3 provides the criteria).38 Typically, patients report flashing rays of light and zigzag lightning and less often, bright colored streaks, halos, or diagonal lines. When i got my floaters i had been on every perscription known to man.

Elementary forms of scotoma are perceived as blank areas, black dots, or spots in the field of vision. Visual field defects can be altitudinal, quadrantic, central, or arcuate. The harsh reality is there are some serious possible complications from the surgery, despite this I do think one day I will build up the courage to get the operation performed on both my eyes. Almost 50 percent have a history of migraine with visual aura. Some patients who report monocular visual disturbance have hemianopsia which they are not aware of since they do not do a cover/uncover test. In retrospect Zoloft caused me more problems than it was worth. Retinal migraine can lead to permanent monocular visual loss.

In a study by mail of 219 migraineurs (32 percent with aura and 68 percent without) who had been seen in a tertiary headache clinic as compared to controls, the presence of both migraine and aura was associated with significantly higher frequencies of autokinesis, metamorphopsia, dyschromatopsia, cinematographic vision, illusionary visual spread, and synesthesia.39 Double vision, inverted 2- and 3-dimensional vision, and altered perception of body weight and size were found more often in patients with migraine without aura than in those with aura. In contrast, aura was associated with the occurrence of visual splitting and corona phenomenon. The authors propose that the sensory and neuropsychological symptoms which occurred more often in migraineurs be termed “migraine trait symptoms” and suggest a prospective study to confirm these findings.
