Brain aneurysm means bulging out of a specific portion of the artery that supplies blood to the brain. It usually develops due to weakness in that particular artery. The aneurysm pops out like a berry. Presence of an aneurysm gets detected with imaging studies like CT scan and MRI. In this article we have explained you the early signs and symptoms of brain aneurysms which you should not neglect.

An unruptured brain aneurysm in most cases doesn’t trigger any symptoms; nonetheless individuals might experience the following with the aneurysm pressing the surrounding nerves in the brain

  • Changes in vision: the individual will experience double vision and the objects will appear blurry.
  • Pain behind eyes: Along with problems in vision, the individual might experience pain behind the eyes
  • Dilated pupils- The eyes tend to appear static with very less of no movement. This gives a characteristic dilated appearance of the pupil. The eyelid might also droop
  • Problems with facial movement- Facial pain in one side might be felt and it would be slightly difficult for the individual to perform facial movement. Doctors might refer this state as facial paralysis.

Since it’s not certain for an individual to experience the aforementioned symptoms, one might not realize that he/she is suffering from brain aneurysm. Thus, delay in diagnosis can push it to the next level which means the aneurysm ruptures and starts leaking blood. It causes internal bleeding and the condition is medically defined as subarachnoid hemorrhage.


Early signs of ruptured brain aneurysm are:

  • Severe headache

As per, National Institute of Neurological Disorders and Stroke (NINDS), “leaking aneurysm may cause these warning headaches, or sentinel headaches”. This implies that the patient will continue experiencing headaches every now and then. However, when the aneurysm bursts open, the individual experiences the worst every headache. It absolutely intense and is nothing close to a normal headache.

  • Nausea, fainting and seizures

Vomiting, tiredness and nausea become persistent. The person loses consciousness for a moment (or might experience seizures or fits) and then regains in a while, along with this he/she is most likely to feel confused without realizing what’s going around in the surroundings.

Due to fainting, the patient might lose balance while walking

  • Stiffness in neck

The nerves of the brain are compressed which is why there’s considerable stiffness and pain in and around the neck.

  • Sensitivity to light

Apart from experiencing the aforementioned problems in vision and eyes, a ruptured aneurysm makes eyes sensitive to light. This condition is known as photophobia.

Note: It’s important to not neglect any of the explained signs and symptoms and we advice patients to call for emergency help in that case.
