Migraine: Causes, Symptoms, Treatment, and Prevention

 

Migraines are more than just headaches. They are a neurological condition that can cause intense, throbbing pain, often on one side of the head, along with nausea, vomiting, and sensitivity to light and sound. Migraine attacks can last anywhere from a few hours to several days, making it difficult to carry out daily activities.

Millions of people worldwide suffer from migraines, but with proper understanding, treatment, and lifestyle changes, the frequency and severity of attacks can often be reduced.

What is a Migraine?

A migraine is a neurological disorder characterized by recurrent episodes of moderate to severe headaches. Unlike ordinary headaches, migraines are often accompanied by additional symptoms such as visual disturbances, nausea, dizziness, and extreme sensitivity to environmental stimuli.

Some people experience warning signs known as aura, which may include flashing lights, blind spots, tingling sensations, or difficulty speaking before the headache begins.

Types of Migraine

1. Migraine Without Aura

The most common type, causing severe headache without warning signs.

2. Migraine With Aura

Occurs with temporary visual or sensory symptoms before the headache starts.

3. Chronic Migraine

Headaches occur on 15 or more days per month for at least three months.

4. Vestibular Migraine

Primarily causes dizziness, balance problems, and vertigo.

5. Hemiplegic Migraine

A rare type that causes temporary weakness on one side of the body.

How is Migraine Diagnosed?

Doctors diagnose migraine based on:

These tests help rule out other neurological conditions.

Avoid self-medication, especially frequent painkiller use, as it may lead to medication-overuse headaches.

Many people find relief with simple lifestyle measures:

• Rest in a dark, quiet room
• Stay hydrated
• Apply a cold compress to the forehead

• Get adequate sleep
