Brain aneurysm is also referred to as cerebral aneurysm, and is an abnormal growth in a blood vessel inside of the brain that can rupture and result in a hemorrhagic stroke. Unruptured aneurysms can be treated with lifestyle changes, prescription medications or surgery. People experiencing symptoms of a brain aneurysm should seek urgent medical help. Consider this information from the Mayo Clinic, National Library of Medicine and the National Institute of Neurological Disorders and Stroke about brain aneurysm symptoms.
Headache
Ruptured brain aneurysms cause sudden, severe headaches. People with ruptured aneurysms may describe the feeling as the worst headache they have ever had. According to the Mayo Clinic, people with severe headaches should seek immediate emergency treatment, because nearly half of ruptured aneurysms result in death.
Mood Changes
People with a ruptured aneurysm may develop sudden mood or personality changes, which may become permanent. People with aneurysms may have difficulty not acting on impulses. They may revert to childlike behavior. Brain aneurysms may also cause people to develop a temper, become easily irritated or unusually sleepy.
Muscle Problems
People with a ruptured brain aneurysm may experience sudden problems with muscle function and control. They may be unable to fully open their eyelids or have paralysis of one side of the face. People with brain aneurysms may also experience sudden weakness, numbness or difficulty coordinating movement of the muscles.
Neurological Changes
Brain aneurysms may cause sudden neurological changes in people, who may not be aware that the changes are occurring. People experiencing an aneurysm may become confused or disoriented and be unable to speak or understand words when they are spoken to. Depending on the location and size of the aneurysm, seizures may develop.
Pain
A brain aneurysm may result in the development of sudden pain in the head and upper body. A large unruptured aneurysm can cause pain within and behind the eye. People with brain aneurysms may also experience neck pain or stiffness after the aneurysm ruptures.
Vision Problems
People with a brain aneurysm may experience problems with their vision. An unruptured brain aneurysm causes the pupil of the eye to dilate, which can make it difficult to see in bright lights or sunshine. People with unruptured brain aneurysms may slowly develop blurry or double vision, and rupture of an aneurysm can cause sudden blurriness or complete loss of vision.
