Migraine is a common neurological disorder characterized by complex and diverse symptoms. Patients may experience symptoms at different stages, ranging from mild prodromal signs to severe pain phases, and even postictal discomfort. Understanding these symptom variations aids in early diagnosis and management of the condition.
The severity and manifestation of symptoms vary from person to person; some patients may only experience mild headaches, while severe cases may be accompanied by neurological disturbances. This article will detail the symptoms of the various stages of migraine, assisting readers in recognizing potential warning signs and understanding when to seek medical assistance.
About 30-40% of patients experience prodromal symptoms 24 hours to several days before a migraine attack. These signs may include:
These signs may be mistaken for general fatigue or stress responses, but for chronic patients, these patterned signs help predict an impending attack.
About 25-30% of patients experience neurological aura symptoms before the onset of headache, which typically last from 10 minutes to 1 hour. Visual auras are the most common, including:
It is noteworthy that about 1/3 of auras may occur without accompanying headaches, a condition known as a silent aura migraine, which still requires professional evaluation to rule out other diseases.
Typical migraine pain has the following characteristics:
Pain may last from 4 to 72 hours, with children typically experiencing shorter attack durations. Many individuals may exhibit autonomic nervous system abnormalities during the headache, such as pupil constriction or facial flushing.
The headache phase is often accompanied by the following physiological responses:
These accompanying symptoms may be more severe than the headache itself, leading patients to avoid environmental stimuli. About 40% of patients will be completely bedridden during the peak of their headache.
The symptoms of migraine may progress through four stages, with a temporal characteristic:
It is important to note that about 60% of patients do not exhibit symptoms that conform to the typical four-stage pattern, and may present irregular overlapping stages or a leapfrog development. Some patients may continue to experience cognitive impairment, known as "brain fog," for several days after headache relief.
Pediatric patients often present with bilateral headaches, and auras may primarily manifest as visual disturbances; adolescent patients may experience severe nausea; adults more commonly exhibit unilateral pulsating pain; and elderly patients may present symptoms that manifest as neck stiffness or balance issues, which need to be differentiated from strokes.
Female patients may experience exacerbated symptoms around their menstrual periods, a phenomenon known as "menstrual migraine," where pain intensity and duration may increase by 30-50%. Hormonal changes during pregnancy or menopause can also trigger changes in symptom patterns.
If any of the following situations occur, immediate medical attention should be sought:
These signs may indicate other serious conditions such as cerebral hemorrhage or meningitis, requiring immediate imaging studies.
Even if not an emergency, the following situations warrant professional evaluation:
Early diagnosis can prevent symptom worsening, and a neurologist may conduct head imaging studies or neuropsychological assessments to develop a personalized treatment plan.
In addition to painkillers, applying a cold compress to the painful side of the head or neck, or resting in a quiet, dimly lit environment may help. Some patients find relief through acupuncture or massage of the cervical spine acupoints, but this should be performed by a qualified physician.
What dietary factors in daily life may trigger migraines?Certain foods such as processed meats containing nitrites, cheeses containing tyramine, chocolate, and caffeinated beverages may trigger migraines. Additionally, excessive dieting or prolonged fasting may also provoke attacks; it is advisable to maintain a regular diet and avoid excessive intake of stimulating foods.
Can migraine patients safely use folk remedies or traditional Chinese medicine?Some traditional Chinese medicines or folk remedies may interact with conventional medications or exacerbate symptoms on their own. It is recommended to consult a neurologist or traditional Chinese medicine practitioner for professional advice before using any alternative therapies, and to regularly monitor changes in the condition.
Why do migraines often accompany nausea or visual disturbances?The pathophysiological mechanisms of migraine involve abnormal excitability of the brain's neurovascular system, which may lead to nausea, vomiting, or "aura symptoms" such as visual zigzag lines. These phenomena are typically related to cortical spreading depression and are part of the typical disease course.
How can one differentiate between migraines and regular tension headaches?Migraine is usually accompanied by pulsating pain, sensitivity to light or sound, and may worsen with activity; tension headaches are often described as a "tight band" pressure pain, with symptoms less affected by environmental stimuli. If attacks occur more than 15 days per month, a detailed neurological evaluation is recommended.
