Migraine is a neurovascular headache and is caused by an interaction between blood vessels and nerve abnormalities. Migraine is the second most common type of primary headache.
Migraine typically lasts anywhere between 4 to several days and is associated with severe pain mostly on one side of the head. However it is possible to affect both sides of the head. Women are more likely to get migraines than men.
It is yet unknown what exactly causes a migraine. Inflammatory processes in the blood vessels of the brain could be involved in the development of migraines. Additionally, a stressful and hectic daily life can promote the development of migraines.
Oftenly, when an individual is predisposed to migraines, they have specific aggravating factors that will bring a migraine on. These factors can vary from person to person and each person has a different trigger.

There are many types of migraines, and they can be categorized by their symptoms. Understanding the type of migraines may help you and your doctor to treat you more effectively. Here they are:
Abdominal migraine: Signs can include severe nausea or vomiting and possible abdominal pain. This type is the most common in children and adolescents.
Hemiplegic migraine: Signs can include temporary motor weakness like one-sided whole-body paralysis. This type is more common in infants and children.
Menstrual migraine: Migraine may be triggered in a woman either just before or during her menstrual cycle.
Migraine with brainstem aura: Formally known as Basilar Migraine. Signs can include dizziness, slurred speech, ringing in the ears, walking abnormality, motion or spinning imbalance, double vision and a lower level of consciousness.
Ocular (Retinal) migraine: Signs can include visual disturbances like flashes of light, wavy lines or blind spots in one eye for approximately 30 minutes.
Silent (Acephalgic) migraine: Signs can include aura symptoms without a headache.
Vestibular migraine: Signs can include extreme sensitivity to motion and dizziness.
Your family doctor or a neurologist can diagnose migraines based on your family history, medical history, symptoms, lifestyle and a physical examination. Mostly, these details are enough to determine or rule out a migraine.
Your doctor may consider further testing like a CT scan or an MRI (Magnetic Resonance Imaging), if your condition is unusual, complex or uncertain. These tests can help doctors to diagnose tumors, strokes, bleeding in the brain, infections and other neurological conditions.
Currently there is no cure for migraines, but there are several treatments and medications available to relieve symptoms. Common migraine treatments include:
Migraines medications either focus on relieving migraine symptoms or on preventing future attacks. You can take pain-relieving medications during a migraine attack to stop the symptoms. However, if you suffer from very severe or frequent migraines, your doctor can suggest regular or daily medications that could help you manage your condition long-term.
OTC Medicines: Over the counter medications are helpful during your migraine treatment plan and work best when taken during the early sign of a migraine. Keep in mind that overuse of OTC pain killers may cause medication-overuse headaches. Other risks may include ulcers and bleeding in the gastrointestinal tract.
Anti-Nausea medicines: When a migraine is accompanied by nausea and vomiting, it is recommended to take anti-nausea drugs.
Triptans: Triptans are prescription drugs that block pain pathways in the brain and balance the chemicals in the brain. Triptans can be taken as pills, shots or nasal sprays.
Opioid medicines: Narcotic opioid medications containing codeine can help relieve migraine symptoms. Your doctor may prescribe these if you cannot take triptans or ergots for some reason. This class of drugs is highly addictive and so are generally used as a last resort if no other treatments are effective.
Sensitivity relief medicines: This drug eases pain, nausea, and sensitivity to light or sound.
If you suffer from frequent or severe migraines, your doctor may prescribe drugs that need to be taken on a regular basis. Here is an outline of some of the classes of drug your doctor may want to use to help you reduce the frequency and severity of your migraines.
CGRP receptor antagonists: This class of drugs works on a protein that’s found around the brain called the Calcitonin Gene-Related Peptide (CGRP) which is believed to be responsible for some of the migraine pain.
Beta-blockers: This class of drugs commonly prescribed for high blood pressure. Beta-blockers can also help reduce both the frequency and intensity of migraines as they decrease the effect of stress hormones on your heart and blood vessels. Possible side effects of beta-blockers are such as fatigue, nausea, dizziness when standing, depression or insomnia.
Calcium channel blockers: This class of drugs is generally used to control blood pressure as they moderate the constriction and dilation of your blood vessels but this also makes them helpful in the management of migraine pain. Possible side effects are such as low blood pressure, weight gain, dizziness or constipation.
Antidepressants: This class of drugs effects on various brain chemicals including serotonin. An increase of serotonin can reduce inflammation and constrict blood vessels, helping alleviate migraines. Possible side effects are such as weight gain and decreased libido.
Anticonvulsants: This class of drugs is generally used to prevent seizures caused by epilepsy and other conditions but they may also alleviate migraine symptoms by calming overactive nerves in the brain. Possible side effects are nausea, vomiting, diarrhea, weight gain, sleepiness, dizziness or blurred vision.
Botulinum toxin type A (Botox): Botox (Botulinum toxin type A) injections in forehead or neck muscles for the treatment of chronic migraine. Generally, these have to be repeated every three months and can be expensive.
Biofeedback uses electronic devices to teach you to control body functions such as heartbeat, blood pressure, and muscle tension
Hormone therapy can be helpful if your migraines are related to your menstrual cycle.
Research has found that some vitamins, minerals and herbs can prevent or treat migraines. These include riboflavin (vitamin B12), coenzyme Q10, Magnesium and melatonin
Resting with your eyes closed in a dark, quiet room
Putting a cool compress or ice pack on your forehead
Doing physical treatments like chiropractic, massage, acupressure, acupuncture and craniosacral therapy
Writing down lifestyle habits like eating, drinking, sleeping, exercise and stressful events in a diary can help you identify what appears to trigger your migraines and what it might be helpful to maintain or avoid in your daily routine. Diary can also help you figure out what positive action to take.
Drinking plenty of liquids
Loss weight if you are overweight
Learn relaxation techniques like meditations, yoga or deep breathing
Eat and sleep on a regular schedule
