Cerebral aneurysm historical perspective
Cerebral aneurysm is defined as
- dilations that occur along the weak points along the arterial circulations within brain. [1]
Size:
- small less than 0.5mm
- Medium 6 to 25mm
- Large greater than 25mm
Types:

Prevalence:
The worldwide prevalence of cerebral aneurysms is approximately 3.2%, with a mean age of 50 and an overall 1:1 gender ratio. This ratio changes significantly after age 50, with an increasing female predominance approaching 2:1, thought to be due to decreased circulating estrogen causing a reduction in the collagen content of the vascular tissue.[1]
