Basilar Migraine | Symptoms, Diagnoses, Treatments and Complications

Basilar Migraine

This is an uncommon type of migraine which usually has its starting point from the brainstem; it may result from the difficulty of blood to the reach the brain due to the constriction of the blood vessels leading to the brain. Other common names associated with this type of migraine include Bickerstaff migraine, basilar artery migraine, basilar-type migraine. The involvement of the basilar artery to the name may sometimes be confused to mean that the attack is initiated from the basilar artery; however, research has shown that the nerves rather than the vessels are the cause of this type of migraine. A basilar migraine affects all ages and it is not gender-based, although, it is more common to females than males as other types of aura.
