Features

• The most common symptoms of an intact (non-ruptured) aneurysm are concentration problems, increased fatigue, problems with balance or coordination, behavior changes, perception problems, vision defects, short-term memory changes, speech changes, and critical thinking.
  
  

Identification

• If a cerebral aneurysm has ruptured, patients generally have severe head pain. This is often defined as "the worst headache" ever experienced.
  
  

Effects

• Common symptoms of a non-fatal aneurysm rupture are blurry vision, double vision, dilated pupils, lost sensation, nausea, vomiting, eye pain, light sensitivity, and neck stiffness.
  
  

Considerations

• Most people (about 60 percent) with an in tact cerebral aneurysm have no symptoms.
  
  

Warning

• Sudden death can be the first symptom of a ruptured cerebral aneurysm, but often there are other symptoms, such as seizure, severe headache or loss of consciousness.
