Migraine with aura
Migraine with aura, what is it?
Definition of migraine with aura
Migraines with aura are different from normal migraines, which are
called migraines without aura. Migraine is a form of headache that manifests
itself in repeated attacks. This results in pain in the head which is usually
unilateral and throbbing.
Aura is a transient neurological disorder that precedes a migraine
attack. Migraine with visual aura, or ocular migraine, represents 90% of cases.
In other cases, pre-migraine may be a sensory disorder or a language disorder.
Causes of migraines including aura
The origins of migraines are still poorly understood.
In the case of migraines, including aura, the activity of neurons in the brain may be disrupted. Decreased cerebral blood flow may be an explanation.
There seems to be a genetic predisposition as well. More research
is needed to better understand the causes of migraine with Aura.
Risk factors
Observational studies have identified some factors that may
encourage migraine attacks. Among them especially:
Positive or negative emotional variation;
An abnormal change in rhythm such as intense physical exertion,
overwork or, conversely, relaxation;
Too little or too much sleep;
Hormonal imbalances such as decreased estrogen levels during
menstruation;
Sensitive changes such as sudden change in light or presence of strong
odor;
Climate change such as the arrival of heat, cold or strong winds;
Changes in eating habits such as drinking, overeating or eating
disorders.
Diagnosis of migraine with Aura
Physical examination is usually sufficient to diagnose migraine. It
is only diagnosed after two migraine attacks with Ara. No other disorder should
be able to explain the onset of headaches.
People with migraines, including Aura
Migraines with aura are not the most common. They only concern 20
to 30% of migraine patients. With or without Ava, migraines can affect anyone.
However, they seem to mainly affect adults before the age of 40. Prepubertal
children seem to have a higher risk of migraines. Finally, statistics show that
women are most prone to migraines. About 18 to 6% of women are infected,
compared to only 15% of men.
