Could it be a disease, or not...?

Question

I've got a colleague, she's a young girl and - nothing to say about her work (she does it very well) but most of the time she's very clumsy, or better, I've always been thinking she was so because she often can't keep objects in her hands, knocking papers, pens and scissors off, and many times she gets wrong letters while writing at PC, making many mistakes (not grammar mistakes but errors like - for example - CARRS instead of CARS ..)
As I was saying I thought she was just a bit clumsy but in the last days I noticed that her hands shake when she's writing or holding something... Could it be a serious disease?? Or simply clumsiness?
