What is a Basilar Type Migraine?
Basilar type migraine is a rare but severe form of migraine that affects the brainstem. This part of the brain controls vital functions like balance, vision, hearing, and speech. Unlike typical migraines, this type can cause dramatic symptoms that often confuse people.
It usually comes with aura symptoms that impact both sides of the body and may be followed by a painful headache, often in the back of the head.

Overview of Migraine Subtypes
There are many types of migraines, but not all are equal. Some are chronic, some come with aura, and others target specific brain areas.
- Migraine with aura: Involves visual changes or sensory symptoms before the headache starts.
- Chronic migraines: Happen more than 15 days a month.
- Hemiplegic migraines: Cause weakness on one side of the body.
- Where does basilar type migraine fit? It belongs to a unique group affecting the brainstem and is often confused with serious neurological events.
What Makes It ‘Basilar’?
The term “basilar” refers to the basilar artery, a major blood vessel at the base of the brain. This artery supplies the brainstem, which controls key functions like balance, vision, and coordination.
- Originates in the brainstem or back of the head
- Tied to blood flow through the basilar artery
- Hits visual and balance centers, not just pain areas
These features set basilar type migraine apart from other neurological migraines
Basilar Type Migraine Symptoms and Aura
People often mistake the symptoms of basilar type migraine for something worse, like a stroke. The warning signs are scary, but knowing what to expect can make them easier to understand and manage.
Most Common Symptoms
Most of the time, basilar type migraine strikes with strong, unusual symptoms before the pain begins.
- Double vision
- Vertigo or severe dizziness
- Tinnitus (ringing in the ears)
- Slurred speech or trouble talking
- Loss of balance or difficulty walking
- Visual aura, like flashing lights or tunnel vision
- Throbbing headache at back of head, often affecting both sides
Stat: About 80% of basilar type migraine cases involve vertigo or dizziness (Journal of Headache and Pain, 2021).
Duration and Onset Patterns
Aura and headache don’t always follow a fixed pattern.
- Aura lasts 5 to 60 minutes
- Headache may start after aura or not at all
- Can look like a stroke or TIA (mini-stroke)
Because of these symptoms, migraine misdiagnosis is common.

Diagnostic Criteria for Basilar Type Migraine (ICHD-3)
There is no blood test or scan that directly confirms basilar type migraine. Doctors follow clinical guidelines to make a diagnosis.
International Classification of Headache Disorders (ICHD-3) Standards
To be diagnosed, the following criteria must be met:
- Two or more aura symptoms like dizziness, slurred speech, or ringing in ears
- Symptoms localized to the brainstem but without motor weakness
- Aura builds up gradually, taking at least 5 minutes
- Headache starts within 60 minutes of aura
“Diagnosis is clinical—there is no blood test or scan to confirm basilar migraines.” – Dr. Anne MacGregor, Migraine Specialist
Differential Diagnosis
Because symptoms are dramatic, doctors must rule out other serious problems first.
- Stroke (CT scan or MRI to check blood flow and damage)
- Epilepsy (EEG may be used)
- Multiple Sclerosis (MRI and spinal tap)
Neurological exams help pinpoint whether the symptoms match migraine diagnostic criteria or point to other disorders.
Causes and Triggers of Basilar Type Migraines
Understanding what causes a basilar type migraine can help you avoid it. While some causes are out of your hands, others can be controlled.
Potential Causes
Some people are more likely to get basilar type migraine type due to inherited or biological factors.
- Family history of neurological migraines
- Hormonal imbalances, especially in women
- Constriction or irritation of the basilar artery
- Overactivity in the brainstem and sensory centers
Common Triggers
Certain activities or conditions can provoke basilar type migraine in those who are susceptible.
- Stress and anxiety
- Lack of sleep or jet lag
- Flashing lights or visual stimuli
- Hormonal shifts (menstrual cycles, menopause)
- Certain foods: chocolate, aged cheese, processed meats
Stat: Women are 3x more likely to have basilar type migraines, especially around menstruation (NIH, 2023).
| Trigger Category | Examples |
|---|---|
| Hormonal | Menstrual cycle, menopause |
| Environmental | Bright lights, loud sounds |
| Lifestyle | Sleep issues, skipping meals |

Treatment and Management of Basilar Migraine
The treatment of basilar migraine focuses on alleviating symptoms and effectively managing acute attacks. It also involves preventive therapy to reduce the frequency and severity of migraine episodes. Here are some key approaches for treating and managing basilar migraine:
Symptomatic Relief for Acute Attacks
During acute attacks, nonsteroidal anti-inflammatory drugs (NSAIDs) and anti-emetics can provide symptomatic relief. NSAIDs, such as ibuprofen, can help to reduce headache pain, while anti-emetics like metoclopramide can alleviate nausea and vomiting commonly associated with migraines.
Recent studies have shown that triptans and ergotamines, which were previously avoided due to concerns about cerebral ischemia, can be beneficial in managing the headache phase of basilar type migraine. These medications work by constricting blood vessels in the brain and reducing inflammation.
Preventive Therapy
To prevent future basilar type migraine episodes, it is important to identify and modify triggers. Keeping a headache diary can help identify patterns and potential triggers such as stress, certain foods, hormonal changes, and environmental factors. Avoiding these triggers can significantly reduce the frequency of migraines.
For individuals with frequent or severe basilar migraines, preventive medications may be recommended. Verapamil, a calcium channel blocker, and topiramate, an antiepileptic drug, are commonly prescribed options. These medications help stabilize blood vessels and reduce the likelihood of migraine attacks.
Non-Pharmacological Therapies
In addition to medication, non-pharmacological therapies can also be helpful in preventing migraines. These include relaxation techniques, acupuncture, massage, cognitive behavior therapy (CBT), and biofeedback techniques.
Relaxation techniques, such as deep breathing exercises and progressive muscle relaxation, can help manage stress and reduce the frequency of migraines. Acupuncture and massage have been shown to provide relief by promoting muscle relaxation and improving blood flow.
Cognitive behavior therapy (CBT) can assist individuals in identifying and managing stress, modifying thoughts and behaviors, and coping with migraines more effectively. Biofeedback techniques, which involve learning how to control bodily responses, have shown promising results in reducing the frequency and intensity of migraines.
Overall, a combination of pharmacological and non-pharmacological approaches tailored to the individual’s specific needs and triggers is essential for effective treatment and management of basilar migraine. Consult with a healthcare professional to develop a personalized treatment plan that addresses your symptoms and improves your quality of life.
Differential Diagnosis of Basilar Migraine
Basilar migraine, with its unique set of symptoms, can sometimes be mistaken for other types of migraines. It is crucial to conduct a thorough differential diagnosis to rule out similar conditions and confirm the diagnosis of basilar migraine. Some of the conditions that should be considered during the diagnostic process include:
- Hemiplegic migraine: This type of migraine is characterized by temporary paralysis or weakness on one side of the body, which can be mistaken for the lack of coordination seen in basilar migraine.
- Migraine with typical aura: This type of migraine includes various visual disturbances, such as flashing lights or blind spots, that may resemble the aura symptoms experienced in basilar migraine.
- Meniere’s disease: Meniere’s disease involves recurring episodes of vertigo, hearing loss, tinnitus, and a feeling of ear fullness. These symptoms can overlap with those of basilar migraine.
- Vestibular disease: Disorders affecting the vestibular system, such as vestibular neuritis or labyrinthitis, can cause symptoms like vertigo and impaired coordination, which may mimic the presentation of basilar migraine.
- Transient ischemic attack (TIA): TIAs are brief episodes of reduced blood flow to the brain, resulting in temporary neurological symptoms similar to those of basilar migraine. It is crucial to distinguish between TIAs and basilar migraine to ensure appropriate management.
- Stroke: Stroke can cause symptoms such as sudden and severe headache, dizziness, slurred speech, and difficulty walking, which can overlap with basilar migraine. Prompt differentiation is essential to provide timely intervention.
- Brainstem arteriovenous malformation: Arteriovenous malformation (AVM) in the brainstem can lead to neurological symptoms like vertigo, difficulty speaking, and impaired coordination, mimicking basilar migraine. Imaging studies are necessary to exclude AVM.
- Tumors: Certain brain tumors, especially those located in the brainstem or affecting blood vessels, can manifest as symptoms similar to basilar migraine. Diagnostic imaging is crucial to identify the presence of tumors.
- Meningitis: Inflammation of the meninges can cause severe headaches, neck stiffness, fever, and neurological symptoms similar to those of basilar migraine. Prompt evaluation is necessary to rule out meningitis.
To confirm the diagnosis of basilar migraine, a comprehensive evaluation, including a detailed history, physical examination, and appropriate diagnostic imaging, should be conducted. These diagnostic measures help eliminate other potential conditions and establish basilar migraine as the definitive diagnosis.
