Migraine with brainstem aura is a rare and complex form of migraine characterized by neurological symptoms related to brainstem functions. It may present with symptoms such as double vision, impaired coordination, dizziness, and other vestibular disturbances. This form of migraine is often accompanied by autonomic disturbances such as nausea, vomiting, and flushing. Episodes of migraine with brainstem aura can last from 20 minutes to several hours and often require a comprehensive approach to diagnosis and treatment, as they require the exclusion of other neurological diseases.
History of the disease and interesting historical facts
The history of migraine goes back many centuries. Since ancient times, migraine has been known as “headache” and was described in the medical texts of Hippocrates and Galen. However, migraine with brainstem aura has only been recognized in recent decades. Interestingly, the first detailed descriptions of the neurological aspects of migraine appeared in the works of such renowned neurologists as Jean-Martin Charcot and Hans Neumann, as well as in the context of modern migraine research, which has begun to take into account the genetic and molecular mechanisms of this condition. For a long time, migraine was considered exclusively a headache until its complex neurological manifestations were identified.
Epidemiology
Migraine with brainstem aura is less common than classic migraine with aura. It is estimated that approximately 16-20% of all migraine patients have aura symptoms, and only a small proportion of these have brainstem symptoms. In the general population, migraine with aura is diagnosed in approximately 12-15% of adults, with a lower prevalence in men and a higher prevalence in women, especially during reproductive age. Epidemiological studies highlight that migraine with brainstem aura is more common in patients with a family history of migraine.
Genetic predisposition to this disease
Recent genetic studies have shown associations with several genes in patients with migraine with brainstem aura. The most studied genes are those responsible for the regulation of neurotransmitters, such as the genes encoding serotonin and dopamine. Mutations in the gene of genetic predisposition to migraine, such as the genes TRPM8 and CACNA1A, may contribute to the development of the pathology. Some studies indicate a significant influence of family history and the frequency of migraine in families, which confirms the presence of a genetic predisposition. The assessment of polygenic risks also reflects the complex nature of the mechanism of migraine occurrence.
Risk factors for the development of this disease
There are many risk factors that can trigger or worsen the symptoms of migraine with brainstem aura. The main ones include:
- Physical factors:
- Physical exertion or overfatigue
- Changes in atmospheric pressure
- Lack of sleep or too much sleep
- Chemical factors:
- Consumption of certain foods (eg chocolate, caffeine, alcohol)
- Hormonal changes, including menstruation in women
- Taking certain medications, such as oral contraceptives
- Psycho-emotional factors:
- Stress and anxiety
- Emotional experiences
Diagnosis of this disease
Diagnosis of migraine with brainstem aura is based on the clinical history and the nature of the manifestations. The main symptoms include:
- Visual disturbances such as flashing lights or double vision
- Impaired vestibular function, including dizziness and impaired coordination
- Autonomic symptoms such as nausea and vomiting
Laboratory tests are not specific for migraine but may be useful in ruling out other conditions. Radiological tests such as MRI and CT scans of the brain may be ordered to rule out organic causes of headache. Differential diagnosis is also important because strokes and other neurological disorders must be ruled out, which requires an analysis of the presentation and timing of symptoms.
Treatment
Treatment of migraine with brainstem aura requires an individual approach and can be both pharmacological and non-pharmacological. General recommendations include:
- Lifestyle changes and stress reduction
- Pharmacological treatment:
- Use of triptans to relieve attacks
- The need to prescribe antidepressants and anticonvulsants
- Prevention – use of β-blockers and antidiabetic immunosuppressants
- Surgical treatment:
- Consideration of the possibility of surgical interventions in the absence of effect from conservative therapy
- Other types of therapy:
- Acupuncture and physiotherapy
- Cognitive behavioral therapy
List of medications used to treat this disease
The main drugs used to treat migraine with brainstem aura include:
- Triptans (Sumatriptan, Rizatriptan)
- NSAIDs (Ibuprofen, Naproxen)
- Antidepressants (Amitriptyline)
- Anticonvulsants (Gabapentin, Topiramate)
- Beta blockers (Propranolol)
Disease monitoring
Monitoring the patient's condition is important to assess the effectiveness of treatment and prevent relapses. Regular monitoring includes:
- Assessment of the frequency and nature of migraine attacks
- Estimated response to therapy and possible side effects
- Determining the prognosis of the disease and potential complications
The prognosis is generally good, but some patients may experience persistent and frequent episodes. Complications may include the development of chronic migraine and deterioration in quality of life.
Age-related features of the disease
Migraine with brainstem aura may present differently in different age groups. Children and adolescents tend to have milder forms and less severe attack episodes. Adults, especially women, often have migraine with pronounced aura symptoms. In older patients, it may present differently, often requiring a reassessment of diagnosis and treatment.
