Etymology: A scatterbrain is, quite literally, a brain that scatters. The word joins "scatter", which goes back to Middle English and likely to a Scandinavian source related to Norwegian "skotra" meaning to scatter, with "brain", the Old English "brægen" that has always named the organ inside the skull. Put together, they describe a mind whose thoughts fly off in all directions instead of staying on one track. The compound is a plain piece of English word-building, formed by joining two existing words rather than borrowing anything from another language. Its sense is figurative from the start: nobody's brain literally scatters, so the image is of attention dispersing like seeds or pebbles thrown across the ground. The word is recorded as a noun for a person and has stayed close to that meaning ever since.
