Brain Aneurysm

Brain-Aneurysm

A brain aneurysm is an outward bulging or ballooning of a weak spot in the wall of an artery that supplies blood to the brain. Although they do not always break but in some cases they may rupture or leak, releasing blood into the brain and causing a hemorrhagic stroke that may cause brain damage or even death.

Location of Brain Aneurysm

The network of blood vessels at the base of the brain called the circle of Willis

Causes of Brain Aneurysm

Aneurysms have a variety of causes including:

  • High blood pressure

  • Atherosclerosis

  • Trauma

  • Heredity

  • Abnormal blood flow at the junction where arteries come together

  • Infections of the artery wall

  • Brain tumors

  • Drug abuse, especially cocaine

Symptoms of Brain Aneurysm

Generally most of the cases of brain aneurysm show no symptoms and may go unnoticed until some diagnostic tests are performed for other illness. In other cases, the symptoms depend upon rupture or unruptured state of aneurysm.

  • Symptoms of Ruptured Aneurysm

  • Severe, sudden and unbearable headache that is different from past headaches and has never occurred before in life

  • Neck pain & stiffness

  • Nausea & vomiting

  • Loss of sensations

  • Fainting or loss of consciousness

  • Double or blurred vision

  • Sensitivity to light

  • Pain above and behind the eye

  • A dilated pupil

  • Seizures

  • Symptoms of Unruptured Aneurysm

  • Severe headaches

  • Blurred vision

  • Neck pain

  • Fatigue

  • Loss of balance and coordination

  • Short-term memory difficulty

  • Decreased concentration

  • Perceptual problems

  • Sudden changes in behaviour & speech

  • Thinking or processing problems

Diagnosis of Brain Aneurysm

Early diagnosis of brain aneurysm prevents rupturing of the vessels and involves the following:

  • Complete history of the patient

  • Thorough physical & neurological examination

  • CT scan

  • Lumbar puncture

  • Angiography

  • MRI scan

  • Cerebral angiogram
