VM Study: Antecedents

What preceded the condition

Antecedents Overview

The survey asked questions about family history with VM and related conditions, as well as possible event immediately prior to the onset of the condition that may have been causal factors. Such links require more focussed examination in order to draw strong conclusions.

Sample title
64.9% Migraineurs in families

The survey exposes a strong family link with non-vestibular migraines

Sample title
7.7% VM in family

Almost all respondents were the only VM sufferers in family

Sample title
27.9% Vestibular disorders in family

More than 1 in 4 have other vestibular patients in the family

Sample title
60.6% with allergic family members

Nearly 40% say this is in their immediate family

Sample title
48.1% High stress before onset

Nearly half report a period of high stress preceding the onset of their symptoms

Sample title
7.2% Stomach issues

Less than 1 in 10 recall stomach issue before their VM symptoms

Family history: Vestibular

Vestibular disorders in family

15% of respondents report a 'strong' family history of vestibular issues, with other sufferers in their immediate family.

Other sources cite rates of 35% of 40 year olds experiencing some form of vestibular dysfunction (http://vestibular.org/understanding-vestibular-disorder) within the general population, so the rates here do not suggest any significant familial disposition.

Migraineurs in the family

While familial rates of vestibular issues are not out of line with what has been reported in the general population, the rates of migraine within the families of respondents are out of range.

The Migraine Research Foundation reports that 1 in 4 families have someone with migraine (http://migraineresearchfoundation.org/about-migraine/migraine-facts/). The strong family history reported here suggests that if a family has one migraineur, they are far more likely to have another.

Sample title

VM in the family

While respondents report moderate rates of vestibular disorder and migraine within the family, it appears that having more than one VM sufferer within a family is rare, with less than one in 10 reporting another member with the condition, even in their extended family.

Sample title

Allergy rates not out of range

Allergies within the general population are relatively common, with the World Allergy Organisation reporting rates anywhere between 10-40% (https://www.allergyuk.org/information-and-advice/statistics). 

At these rates, a report of 39.4% in immediate family and 21.1% in the extended family doesn't suggest that VM sufferers are any more likely to come from a family with allergies.

Sample title

Stress before onset

48.1% report a period of high stress or anxiety prior to the onset of VM symptoms. VM has long been linked to emotional and cognitive disorders and is often treated with antidepressants.

This might be interpreted as one of the most interesting findings of the survey, and warrants further, more focussed research.

Want to dig into the data yourself?

The VM Survey examined background factors that may have a relationship to the condition of the survey participants. These included familial history as well as events that preceded their diagnosis.

Further focussed examination will be required to draw any conclusions about the impact of these factors on the prevalence of the vestibular migraines.
