Migraines: how do they affect the body?

Migraines are a common yet debilitating condition that affect millions of people worldwide. Unlike typical headaches, migraines come with a variety of symptoms that can significantly disrupt daily life. From throbbing pain to sensitivity to light and sound, understanding the nature of migraines is crucial for managing them effectively. Revered GP Dr Joshua Plaut  explores what migraines are, their types, common triggers, how they are diagnosed, and the treatment options available.

What are migraines?

Migraines are a neurological condition that can cause intense, throbbing headaches. Unlike typical headaches, migraines often come with additional symptoms such as nausea, sensitivity to light and sound, and, in some cases, visual disturbances known as "auras." These headaches can last from a few hours to several days, which can significantly impact daily life.

Migraines occur due to changes in the brain's blood vessels and chemical activity, although the exact cause isn’t fully understood. What we do know is that migraines can be triggered by a variety of factors, ranging from stress and lack of sleep to certain foods and environmental changes. Migraines often run in families, indicating that there can be genetic element. Migraines can affect anyone, though they are more common in women.

What are the different types of migraines?

Migraines are not all the same, and it's helpful to understand the different types. The most common is a migraine without aura, which presents as a severe headache but without any warning signs. On the other hand, a migraine with aura involves visual or sensory disturbances, such as flashes of light, zigzag patterns, or temporary numbness, typically appearing before the headache begins.

Another type is the chronic migraine, defined as having migraine symptoms on 15 or more days per month. This type can be especially debilitating and requires careful management. Additionally, hemiplegic migraines are rare but can cause temporary weakness or paralysis on one side of the body, mimicking a stroke. Because symptoms can vary widely, it’s important to discuss them with a healthcare provider for accurate diagnosis and treatment.

What triggers a migraine?

Migraine triggers vary from person to person, but several common factors are known to play a role. Stress is one of the biggest culprits, as it causes changes in hormone levels and affects brain chemistry. Sleep disruptions—whether too much or too little—can also be problematic, as the brain relies on regular sleep patterns for proper functioning.

Dietary triggers, such as caffeine, alcohol, aged cheeses, and processed foods, are frequently reported by migraine sufferers. Even environmental factors, like bright lights, loud noises, or strong smells, can provoke an attack. Keeping a migraine diary, where you track your symptoms, diet, and activities, can help identify personal triggers and aid in managing the condition.

How are migraines diagnosed?

Diagnosing migraines typically starts with a detailed discussion of your symptoms. Your doctor will ask about the nature of your headaches—how frequent they are, what they feel like, and any associated symptoms such as nausea or visual changes. A thorough medical history, including family history of migraines, will also help in identifying the condition.

In some cases, additional tests like CT scans or MRI scans may be needed to rule out other potential causes of headaches, such as tumours or bleeding in the brain. However, these tests are usually not required unless there are unusual or severe symptoms.

How can migraines be treated?

Migraine treatment generally involves a combination of lifestyle changes, medication, and sometimes preventive measures. Acute treatment aims to stop the migraine once it has started. This may include over-the-counter pain relief, like paracetamol or ibuprofen, or prescription medications known as triptans, which are specifically designed for migraines.

For those who experience frequent migraines, preventive treatment may be necessary. This can involve daily medications, such as beta-blockers (which lower blood pressure), antidepressants, or even anti-seizure medications. Some patients also benefit from botulinum toxin (Botox) injections, which have been shown to reduce migraine frequency in chronic sufferers.

Lifestyle modifications are key as well. Regular sleep patterns, a balanced diet, stress management techniques, and staying hydrated can all play a part in reducing the number and severity of migraine attacks.
