Circumlocution refers to:
- A discourse that wanders from the point, only eventually to return to the original subject matter, as seen in fluent aphasias;
- A response to word-finding difficulties, as in early Alzheimer’s disease or nonfluent aphasias: in response to familiar pictures, patients may comment that the name is on the tip-of-the-tongue but they cannot access it, and therefore give alternatives (e.g.,"gardener’s friend" or "beetle" for ladybird).
