Migraine-associated vertigo

vestibular migraine ( VM ) is a vertigo associated with migraine, either as a migraine symptom or as a neurologic disorder; when referred to as the disease itself, it is also called migraine related vertigo ( MAV ), vertigo migraine , or migraine related vestibulopathy .

A 2010 report from the University of British Columbia published in the journal Headache says that it "... emerges as a popular diagnosis for patients with recurrent vertigo.Although some authors believe that" vertigo-related migraines, " clinical as well as biologically unreasonable as a migraine variant. "Epidemiological studies leave no doubt that there is a strong relationship between vertigo and migraine.

Classification

Significant paroxysmal positivity of parotysmal - Migraine is commonly associated with BPPV, the most common vestibular disorder in dizzy patients. Both can be linked by genetic factors or by vascular damage to the labyrinth.

Disease MÃÆ' Â © niÃÆ'¨re - There is an increase in the prevalence of migraine in patients with MÃÆ'Â © niÃÆ'¨re disease and migraines leading to greater susceptibility to developing the disease MÃÆ'Â Â © niÃÆ'¨re. But they can be distinguished. Diseases MÃÆ'Â Â © niÃÆ'¨re can last for days or even years, while migraines usually do not last more than 24 hours.

Motion sickness is more common in patients with migraine.

Psychiatric Syndrome Dizziness and rotating vertigo are the second most common symptom of panic attacks, and they can also appear as symptoms of severe depression. Migraine is a risk factor for developing severe depression and panic disorder and vice versa.

Signs and symptoms

Vertigo is a medically recognized term for vestibular system disorder symptoms. This may include the feeling of rotation or the sensation of the illusion of motion or both. The general term dizziness is used by non-medical people for these symptoms but often refers to feelings of dizziness, dizziness, drowsiness, or fainting, all of which must be distinguished from the actual vertigo, since the latter symptoms may have other causes.

Motion sickness is more common in migraine patients (30-50% more than in controls). Benign paroxysmal vertigo in childhood is an example of vertigo associated with migraine where headache is not common. Basilar artery migraine (BAM) consists of two or more symptoms (vertigo, tinnitus, hearing loss, ataxia, dysarthria, visual symptoms in both hemifields or both eyes, diplopia, bilateral paresthesias, paresis, consciousness loss and/or loss of consciousness) followed by pulsating headache. Hearing symptoms are rare. However, one study showed a low-tone sensorineural hearing loss that fluctuated in over 50% of patients with BAM with apparent changes in hearing just before the onset of migraine headaches. Vertigo attacks usually coincide with headaches and a family history is usually positive. Diagnostics should rule out: TIA, and paroxysmal vestibular disorders accompanied by headaches.

There is also familial vestibulopathy, familial benign recurrent vertigo (fBRV), in which vertigo episodes occur with or without migraine headaches. The test may indicate a deep vestibular loss. This syndrome responds to acetazolamide. Familial hemiplegia migraine (FHM) has been associated with mutations in the calcium channel gene. (Ophoff et al. 1966 cf. Lempert et al.)

Pathophysiology

The pathophysiology of MAV is not fully understood; both central and peripheral defects have been observed.

Diagnosis

MAV is not recognized as a different diagnostic entity. Lembert and Neuhauser propose criteria for vertigo-related migraines that are uncertain and possible.

The diagnosis of vertigo is definitely migraine related including case history:

• episodic vestibular symptoms at least moderate severity;
• current or previous migraine history by 2004 Classification of International Headaches Disorders ;
• one of the following migraine symptoms for two or more vertigo attacks: migraine headaches, photophobia, phonophobia, visual or other aura; and
• Other causes are ruled out by a proper investigation.

The possible diagnosis of migraine-related vertigo includes a history of episodic vestibular symptom cases at least moderate severity and one of the following:

• current or previous migraine history in accordance with 2004 International Classification of Headache Disorders ;
• migraine symptoms during vestibular symptoms;
• migraine precipitate vertigo in more than 50% of attacks, such as food triggers, sleeplessness, or hormonal changes;
• response to migraine drugs in more than 50% of attacks; and
• Other causes are ruled out by a proper investigation.

Note that, in both of the above criteria, headaches are not necessary to make a migraine-related vertigo diagnosis.

They added that, in patients with a clear history, no vestibular test was required. Other historical criteria that help in the diagnosis of vertigo associated with migraine are vertiginous symptoms throughout the entire patient's life, long history of motion intolerance, sensitivity to environmental stimuli, the illusion of environmental motion, and the vertigo that evokes the patient.

Treatment

Treatment of vertigo-related migraines is similar to those for migraine in general.

Epidemiology

The prevalence of migraine and vertigo was 1.6 times higher in 200 clinical dizziness patients than in 200 age and sex controls from orthopedic clinics. Among patients with unclassified or idiopathic vertigo, the prevalence of migraine was shown to increase. In another study, migraine patients reported 2.5 times more vertigo as well as 2.5 more headaches during the headache period compared to controls.

MAV can occur at any age with a female: male ratio between 1.5 and 5: 1. Family incidents are not uncommon. In most patients, migraine headaches begin early in life rather than MAV with a headache-free period before MAV manifestations.

In the diary study, the prevalence of 1 month MAV was 16%, higher frequency of MAV and longer duration in days with headache, and MAV was a risk factor for co-morbid anxiety.
