I experienced a stroke. What is the risk that my children may have the same experience?

After experiencing a sub arachnoid haemorrhage (SAH) at age 57, I asked several experts the question of whether my children were at risk of the same experience. The general advice was the following: 1. Some strokes are hereditary, however with smaller families now, the risk of a hereditary stroke is that much less. Unless there are 2 or more members of the family (possibly across multiple generations) with similar experiences, there is a low risk of an inherited stroke. 2. In the specific case of an aneurism, the risk can be assessed by a CT scan. However, if an aneurism is found, the operation to correct it is itself high risk and may result in prematurely causing other health problems. Hence, unless children are seriously concerned about the risk, it is probably better to not have any scan unless any symptoms appear. So far our children have taken the path of not being scanned for aneurisms, but they are of this option if they ever choose to take it up in the future.
