Migraines are a prevalent and debilitating neurological condition that affects millions of people worldwide. Within the realm of migraines, there exists a subtype known as “migraines with aura,” which adds an intriguing layer of complexity to an already intricate condition. In this introductory article, we will delve deep into understanding migraines with aura, exploring their definition, symptoms, and how they distinguish themselves from regular migraines.
What Are Migraines With Aura?
Migraines with aura, also known as “classic migraines,” are a distinct subtype of migraine headaches characterized by the presence of neurological symptoms preceding or accompanying the headache. These neurological symptoms, known as “aura,” typically manifest as visual disturbances, but they can also affect other senses and motor functions. Understanding migraines with aura requires delving into the nature of these unique prelude experiences.
The Aura Experience
Visual Disturbances
Visual disturbances are the most common manifestation of aura in migraines. People experiencing a migraine with aura may describe their visual symptoms as:
Scotomas: These are blind spots or areas of reduced vision that may appear as shimmering zigzag lines, flashing lights, or even temporary blindness in one eye.
Fortification Spectra: This term refers to the visual perception of a geometric pattern resembling a fortress or castle wall. These patterns often expand and move across the visual field.
Photophobia: Heightened sensitivity to light, known as photophobia, is a common accompaniment to aura. Even normal lighting levels can be painful during this phase.
Other Sensory Disturbances
While visual disturbances are the hallmark of aura, other sensory experiences can also occur. These may include:
Auditory Hallucinations: Some individuals with migraines with aura report hearing noises, ringing in the ears, or even music that isn’t present.
Olfactory Hallucinations: Unusual or unpleasant smells may be perceived, even when no source is present.
Tingling Or Numbness: Some people experience tingling or numbness, often starting in the face or hands and spreading gradually.
Language Difficulties: Difficulty in speaking or understanding speech may occur in rare cases.
The Onset Of Migraines With Aura
One of the intriguing aspects of migraines with aura is the predictability of their onset. Unlike regular migraines, where the headache can seemingly strike at any time, migraines with aura often follow a distinct pattern:
Aura Phase: This is the initial phase where the aura symptoms occur. It can last anywhere from a few minutes to an hour.
Headache Phase: Following the aura phase, the headache typically begins. It is often described as a throbbing and intense pain, usually on one side of the head. During this time, people often feel sick, throw up, and are very sensitive to light and sound.
Postdrome Phase: After the headache subsides, individuals may experience a postdrome phase, often described as a “migraine hangover.” This phase can involve fatigue, cognitive difficulties, and an overall sense of malaise.
How Migraines With Aura Differ From Regular Migraines?
Migraines with aura differ from regular migraines primarily in the presence of the aura phase. Regular migraines, also known as “migraines without aura” or “common migraines,” lack these distinctive prelude experiences. Instead, they typically involve only the headache phase and the postdrome phase.
To Summarize The Key Differences:
Aura Presence: The presence of aura is the defining characteristic that sets migraines with aura apart from regular migraines. While some migraine sufferers may experience both types at different times, others exclusively experience one or the other.
Symptom Duration: A migraine with aura includes an additional phase, the aura phase, which can last from minutes to an hour. In contrast, regular migraines typically consist of the headache phase followed by the postdrome phase.
Symptom Variety: Migraine with aura presents a broader spectrum of sensory and motor disturbances, such as visual, auditory, olfactory, and tactile hallucinations, as well as motor weakness. Regular migraines, on the other hand, primarily involve severe headache pain.
Predictability: Migraines with aura often follow a more predictable pattern due to the aura phase’s warning signs, whereas regular migraines can be more unpredictable in their onset.
Possible Causes And Triggers
The precise cause of migraines, whether with or without aura, remains the subject of ongoing research. However, several factors are believed to contribute to the development of migraines with aura:
Genetics: A family history of migraines can increase the likelihood of experiencing migraines with aura.
Neurological Factors: Abnormalities in brain structures and chemical neurotransmitters, such as serotonin, are believed to play a role.
Hormonal Changes: Fluctuations in estrogen levels, such as those occurring during the menstrual cycle, pregnancy, or menopause, can trigger migraines with aura in some individuals.
Environmental Triggers: Common triggers for migraines, including stress, lack of sleep, certain foods (e.g., aged cheese, processed meats), and sensory stimuli (bright lights, loud noises), can also provoke migraines with aura.
Diagnosis And Treatment
A full medical history, a physical exam, and sometimes neuroimaging tests to rule out other possible reasons for the symptoms are usually needed to diagnose headaches with aura. Keeping a migraine diary that tracks the frequency, duration, and potential triggers of migraines can also aid in diagnosis.
Once diagnosed, the management of migraines with aura often includes:
Medications: Acute treatment involves medications to relieve the pain and symptoms during an attack. Preventive medications from South Valley Neurology might also be given to lower the number and intensity of headaches.
Lifestyle Modifications: Finding and staying away from triggers, sticking to a normal sleep plan, dealing with stress, and eating well can all help lower the number of headaches you get.
Biofeedback And Relaxation Techniques: Learning to control physiological functions that contribute to migraines, such as muscle tension and heart rate, can be effective in reducing migraine frequency.
Alternative Therapies: Some individuals find relief from migraines with acupuncture, chiropractic care, or herbal supplements. However, the efficacy of these approaches can vary.
Conclusion
Migraines with aura are a captivating yet challenging variant of the common migraine headache. The distinctive aura phase, characterized by sensory and motor disturbances, sets them apart from regular migraines. Understanding migraines with aura involves recognizing their unique symptoms, potential causes, and the available treatment options.
For individuals living with migraines with aura, seeking professional medical advice and adopting a proactive approach to manage triggers and symptoms can significantly improve their quality of life. Additionally, ongoing research into the causes and treatment of migraines continues to shed light on this complex neurological condition, offering hope for more effective management and relief in the future.
