Headaches can be caused by various factors. Two of the most common causes are aneurysms and migraines.

Knowing the differences between the symptoms of these two types of headaches can help you identify the underlying condition and seek appropriate treatment. Here we compare the symptoms of aneurysms and migraines.

What is an aneurysm?

An aneurysm is a bulge or ballooning in a blood vessel. It can occur in any part of the body, but when it happens in the brain, it is called a cerebral aneurysm. Aneurysms are caused by weakening and thinning of the arterial walls.

When an aneurysm ruptures, it can lead to a life-threatening condition called subarachnoid hemorrhage, which is bleeding within the space surrounding the brain.

What are the symptoms of aneurysms?

The symptoms of an aneurysm depend on its size and location. Small aneurysms may not cause any symptoms and are often found incidentally during imaging tests. However, large or ruptured aneurysms can cause the following symptoms:.

1. Sudden severe headache

A sudden, severe headache is the hallmark symptom of a ruptured aneurysm. The headache is often described as “the worst headache of my life” and can start suddenly or build up gradually over a few days or weeks.

The pain is usually felt on one side of the head.

2. Nausea and vomiting

Many people with a ruptured aneurysm also experience nausea and vomiting, which can be severe and frequent.

3. Stiff neck

A stiff neck is a common symptom of subarachnoid hemorrhage. The neck stiffness is caused by blood in the subarachnoid space irritating the nerves and causing pain.

4. Sensitivity to light

Sensitivity to light, or photophobia, can occur in some people with aneurysms. The bright light can worsen the headache and cause eye discomfort.

5. Loss of consciousness

In severe cases, a ruptured aneurysm can cause loss of consciousness or coma.

What is a migraine?

A migraine is a type of headache that is usually accompanied by other symptoms, such as nausea, vomiting, and sensitivity to light and sound. The pain is often described as throbbing or pulsing and is usually felt on one side of the head.

What are the symptoms of migraines?

The symptoms of migraines can be different from person to person, but some common ones include:.

1. Headache

A severe, throbbing headache, usually on one side of the head, is the most common symptom of migraines.

2. Nausea and vomiting

Many people with migraines also experience nausea and vomiting, which can be severe and frequent.

3. Sensitivity to light and sound

Migraines can make you sensitive to light and sound. You may find that bright light worsens your headache, or that loud noises make it difficult to concentrate.

4. Aura

Some people with migraines experience an aura, which is a temporary disturbance in vision, such as seeing flashing lights or wavy lines.

5. Fatigue

Many people feel tired or fatigued after a migraine attack.

When to seek medical attention?

If you experience sudden, severe headache, especially if it is the worst headache of your life, seek medical attention immediately. A ruptured aneurysm can lead to a life-threatening condition, and prompt treatment is essential for survival.

If you have frequent headaches or migraines that interfere with your daily life, talk to your healthcare provider. You may benefit from preventive or acute treatments to manage your symptoms.
