A basilar artery migraine, also known as basilar migraine or migraine with brainstem aura, is a type of migraine that originates in the brainstem. It is characterized by the presence of aura symptoms that can include vertigo, difficulty speaking, impaired hearing, double vision, and loss of muscle control. These symptoms can be accompanied by a throbbing headache that typically starts on one side of the head and spreads. Basilar migraine episodes can last anywhere from 4 to 72 hours and can be debilitating for the individual. It is more common in females and often begins in childhood or the teen years. Triggers for basilar migraine can include stress, alcohol, lack of sleep, hormonal changes, and certain foods. It is important to seek medical attention to ensure a proper diagnosis and appropriate management of basilar artery migraines.

Pathophysiology of Basilar Migraine
Basilar migraines, once thought to be caused by basilar artery spasms, are now known to be a subtype of migraines with aura. This type of migraine is characterized by the firing of nerves in the brainstem, leading to the manifestation of aura symptoms. The underlying pathophysiology of basilar migraines is related to a phenomenon known as cortical spreading depression.
Cortical spreading depression is a self-propagating wave of depolarization that occurs in neurons and glia. In basilar migraines, this wave primarily affects the brainstem or both occipital hemispheres, as opposed to typical migraines with aura, which usually involve a unilateral hemisphere. The aura symptoms experienced in basilar migraines, such as vertigo, impaired hearing, and double vision, are believed to be a result of this cortical spreading depression.
In contrast to the earlier belief of vascular pathology in basilar migraines, there is currently no proven evidence of basilar artery spasms contributing to the pathophysiology of this condition. Instead, the focus is on the abnormal neuronal activity that occurs in the brainstem and its role in triggering the aura symptoms characteristic of basilar migraines.
Symptoms of Basilar Migraine
The symptoms of basilar migraines can vary, but they often include:
- Vertigo
- Dysarthria (difficulty speaking)
- Diplopia (double vision)
- Tinnitus (ringing in the ears)
- Impaired hearing
- Lack of coordination
- Confusion
- Loss of consciousness
These symptoms may be accompanied by typical aura symptoms such as:
- Photopsia (flashes of light)
- Loss of vision
- Paresthesia (tingling or numbness)
- Language problems
It is important to note that all aura symptoms are reversible, and they are often followed by an occipital headache that can last for hours to days. It’s worth mentioning that not all individuals with basilar migraines experience a headache; some may only have aura symptoms.
Diagnosis of Basilar Migraine
The diagnosis of basilar migraines is based on specific criteria outlined by the International Classification of Headache Disorders. In order to confirm a diagnosis of basilar migraine, healthcare professionals will consider the presence of aura symptoms that originate from the brainstem or both occipital hemispheres. The duration and characteristics of the aura symptoms, as well as the association of the migraine headache with the aura, are also taken into account. It is crucial to rule out other conditions that can mimic basilar migraines, such as stroke, tumors, and infections. Diagnostic tests such as brain imaging (MRI or CT scans) and EEG may be necessary to exclude other pathological causes.
If you suspect that you may be experiencing basilar migraines, it is important to consult a healthcare professional for a proper evaluation and diagnosis. They will be able to provide you with accurate information and develop a suitable treatment plan tailored to your specific needs.
Diagnostic Criteria for Basilar Migraine
| Criteria | Explanation |
|---|---|
| Aura Symptoms | Presence of aura symptoms originating from the brainstem or both occipital hemispheres |
| Aura Duration | Duration of aura symptoms lasting minutes up to 60 minutes |
| Aura Characteristics | Visual, sensory, or language disturbances during the aura phase |
| Headache Association | Migraine headache that follows the aura phase |
It is crucial to note that the diagnosis of basilar migraines should be made by a healthcare professional based on a thorough evaluation of your symptoms and medical history. Diagnostic tests may be necessary to exclude other potential causes and ensure an accurate diagnosis.
Treatment and Management of Basilar Migraine
When it comes to the treatment and management of basilar migraines, the focus is on alleviating symptoms during acute attacks and preventing future episodes. Here are some approaches that can help:
Medications for Acute Attacks
During acute attacks, nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, and anti-emetic medications, like metoclopramide, can be used to relieve pain and nausea. However, it’s important to avoid triptans and ergotamines, as they may potentially increase the risk of cerebral ischemia.
Preventive Therapy
In order to reduce the frequency and severity of basilar migraine episodes, preventive therapy may be recommended. Medications such as verapamil, a calcium channel blocker, and topiramate, an anticonvulsant, have shown effectiveness in managing basilar migraines.
Lifestyle Modifications
In addition to medication, making certain lifestyle modifications can make a significant difference. Techniques to reduce stress, regular exercise, following a balanced diet, and prioritizing adequate sleep can all help prevent or manage basilar migraines. It’s important to identify and avoid triggers, such as alcohol and certain foods, that may contribute to migraine episodes.
Non-Pharmacological Therapies
Various non-pharmacological therapies can complement medical treatment in managing basilar migraines. Relaxation techniques, such as deep breathing and progressive muscle relaxation, acupuncture, massage, cognitive behavior therapy (CBT), and biofeedback are alternative approaches to consider.
Remember, finding the right treatment and management plan may require some trial and error. It’s important to work closely with a healthcare professional to tailor a strategy that is most effective for you.
Differential Diagnosis of Basilar Migraine
When experiencing symptoms associated with basilar migraine, it is crucial to differentiate them from other conditions with similar presentations. The following conditions are among the differential diagnoses to consider:
