Headache and migraine
- General weakness
- Intolerance to sounds
- Intolerance to bright light
If you notice at least 2 of these symptoms, it is very likely that you have migraine. But you should consult a neurologist to confirm the diagnosis.
Physical activity increases the pain. Pain attacks might occur from once per year to once per week and can last from 4 days to 3 days. Migraines affect 10% of the population. ⅔ are women under 45, due to the influence of sex hormones.
If the pain is not connected with some other disease – as is the case for migraines – it is considered a primary headache. The most common type of primary headache is the tension headache. It occurs if you have stress or problems with the cervical spine. This pain does not increase during physical exercise. It might cause loss of appetite without vomiting. The pain is either episodic – 3-4 times per week – or chronic – more than 15 days per month for half a year.
Cluster headaches are another type of a primary headache. They is quite rare: 1 case for 1000 people, among them 1 woman for 6 men. Cluster is a period of repeated attacks, which last from several weeks to several months. Usually, attacks appear at the same time every day. They are short, lasting from 15 minutes to 3 hours, but extremely painful – involving strong sensations around the eyes, tearing, reddening, and a runny or stuffy nose.
How do migraines start?
- Precursors. Your mood swings from depression and irritability to enthusiasm and excitement. You yawn and have difficulties with speech and reading. Forerunners might start up to 3 days before the pain attack. According to National Center for Biotechnology Information, if you have forerunners, there is a 72% probability the attack will appear.
- Aura. Reversible visual and speech disorders, numbness lasting for 5-60 minutes. To reduce the pain you can take painkillers. This phase might be absent.
- Heavy ripple headache, increasing with minimal physical activity, even walking. It lasts from 4 hours to 3 days and stops on its own. It might be followed by vomiting, nausea, and intolerance to sounds and bright light.
- Recovery. 94% of people have residual symptoms during this phase: mood changes, weakness, and loss of appetite. These disappear in a day.
What causes an attack?
- Female hormones: oral contraceptives, pregnancy, hormone replacement therapy, changes in estrogen levels during one’s menstrual cycle
- Foods and drinks that can constrict blood vessels, such as alcohol and caffeine
- Hunger (decrease of glucose level in blood)
- Stress: emotional or physical (hard workouts or increased sexual activity, injuries)
- Sensory stimulus: bright lights, loud sounds, strong smells, passive smoking
- Changes in sleep cycle
- Weather changes: drops in atmospheric pressure
- Medications: oral contraceptives and vasodilators (nitroglycerin)
Also citrus, chocolate, wine, products with tyramine might cause an attack, however, these reactions are individual and not scientifically proved.
How migraine works?
Brain vessels become narrow. There is a lack of oxygen in nerve cells, which disturbs the process of positive ions coming in cells. This creates a potential sufficient to arouse other nerve endings. As a result, there is an excitation of sensitive trigeminal nerve fibers in the vessels of the brain and in the meninges.
They deliver impulses to the cortex, which is responsible for perceiving pain. The path of painful impulses goes through the nucleus that regulates physiological functions. This causes nausea, vomiting, yawning, watering, loss of appetite, tiredness, irritability, and depression during migraine.
Additional bunches of the trigeminal nerve go into the brain cortex that controls hearing, vision and smell, which causes the aura, and specific headache. Some researchers say that migraine pain might be caused by the improper functioning of neurons responsible for pain treatment. However, in this case, the cause of excitation of such neurons is the excitation wave in the brain.
Is migraine dangerous?
However, a migraine with an aura is different. Researchers observed 27,798 women for 12 years and came to the conclusion that migraines with an aura increase the risk of a heart attack by more than 50 percent, and their risk of stroke more than by 200 percent. There is other research that showed a connection of migraine with aura and cardiovascular diseases. However, the cause is not the migraine itself, but the blood supply disorders which are connected with it. To reduce the risk of a heart attack or stroke you should take measures to prevent cardiovascular diseases.
There is evidence that migraines also change the function and structure of the brain. So it is obvious that a migraine is not merely a pain syndrome, but a series of significant changes taking place inside the brain. So preventive measures and treatment are essential.
How do I treat a migraine?
- Reduce pain
- Prevent future attacks
- Slow down changes inside the brain
Migraine attacks trigger stress, sleep disorders, hunger, and overeating. This means that the reason for the brain’s excitability might be a sensitivity to changes in the metabolism, which is regulated by the hypothalamus. That is why doctors often prescribe medications that affects receptors of ghrelin, leptin, and orexin, help to control weight, stress, and sleep, and prevent overeating and obesity.
Changes in the structure and functions of the brain might occur in different parts, which makes the treatment of migraines a difficult process. We recommend to visit a doctor to find the right treatment.
How do I control my migraines?
- Regulate your sleep cycle: wake up and go to bed at the same time every day. Sleep Cycle, Sleep as Android, Sleep Time, and other sleep-tracking apps/gadgets will help you optimize sleep length and choose an ideal time for falling asleep
- Get some exercise: aerobic fitness can reduce the frequency of migraine attacks
- Maintain an optimal weight: a meta-analysis of 12 studies which covered 300,000 people showed that there is a correlation between migraines and weight disorders (both being overweight and underweight)
- Eat regularly
- Avoid dehydration. You can control your water consumption with trackers, e.g. HealBe GoBe or smart glasses like Sportline HydraCoach, or Pryme Vessyl
Monitor your health with Welltory measurements and migraine diaries, like Migraine Diary or Migraine Buddy to clarify the causes of your migraine. This will help you find correlations between attacks and level of stress and energy, sleep quality, and nutrition, and determine what exactly causes a headache. One’s general susceptibility to migraines reduces only with age, but you can control the frequency and duration of painful attacks.
