Who is at risk for this disorder?This questions is asking if there is anything that makes a person more likely to get it. Not if they already have it.

This definitely depends on the disorder.

Explanation:

But, let's take diabetes for an example. If you eat too much sugar, and always have high insulin levels, you're most likely to get diabetes when you grow older.

Another Example:

Let's take dyslexia. There is really nothing for this disorder to make you get it, you just simply have trouble with something.
