Brain tumours and brain aneurysms have quite similar symptoms and signs but are nevertheless distinctly different. A brain tumour for example, is caused by cancer whereas a brain aneurysm is typically caused by damage to arteries within the brain.

Composition of a brain aneurysm

A brain aneurysm is a "bulging out" of an artery in the brain that disrupts the normal blood flow. It is estimated that up to 1 in 15 people will develop a brain aneurysm at some point in their life.

Composition of brain tumour

A brain tumour is made up of cancerous cells and brain tissue.

Signs and symptoms of brain tumour

The signs and symptoms of a brain tumour don't definitively indicate one, as they can be signs of a variety of conditions. They can include headaches, nausea or vomiting, changes in speech, vision or hearing, problems balancing or walking, changes in mood, personality or concentration, memory problems, muscle jerks or twitching, seizures, numbness or tingling of the extremities.

Signs and symptoms of a burst aneurysm

The most common sign of a burst aneurysm is that the person complains of the worst headache of their life. They also include nausea, vomiting, stiff neck or neck pain, blurred vision or double vision, pain above and behind the eye, dilated pupils, sensitivity to light, and loss of sensation.

Signs and symptoms of an unruptured brain aneurysm

According to, patients may not experience symptoms. Roughly 40 per cent of patients will experience peripheral vision deficits, thinking or processing problems, speech complications, perceptual problems, sudden changes in behaviour, loss of balance and coordination, decreased concentration, short-term memory difficulty and fatigue.
