Interesting facts on Brain Aneurysm by Dr Winnie Lim Khoo, Neurologist

  • The annual rate of rupture is approximately 8–10 per 100,000 people or about 30,000 people in the United States suffer a brain aneurysm rupture. There is a brain aneurysm rupturing every 18 minutes. Ruptured brain aneurysms are fatal in about 40% of cases. Of those who survive, about 66% suffer some permanent neurological deficit.
  • Brain aneurysms are most prevalent in people ages 35–60, but can occur in children as well. The median age when aneurysmal hemorrhagic stroke occurs is 50 years old and there are typically no warning signs. Most aneurysms develop after the age of 40.
  • Most aneurysms are small, about 1/8 inch to nearly one inch, and an estimated 50 to 80 percent of all aneurysms do not rupture during the course of a person’s lifetime. Aneurysms larger than one inch are referred to as “giant” aneurysms and can pose a particularly high risk and can be difficult to treat.
  • Accurate early diagnosis is critical, as the initial hemorrhage may be fatal, may result in devastating neurologic outcomes, or may produce minor symptoms. Despite widespread neuroimaging availability, misdiagnosis or delays in diagnosis occurs in up to 25% of patients with subarachnoid hemorrhage (SAH) when initially presenting for medical treatment. Failure to do a scan results in 73% of these misdiagnoses. This makes SAH a low-frequency, high-risk disease. #brain #aneurysm #stroke #headache #migraine #pain #specialist #neurologist #manila #winnielimkhoo #health #tips #advise
