Most auras are visual and are described as bright shimmering lights around objects or at the edges of the field of vision (called scintillating scotomas) or zigzag lines, wavy images, or hallucinations. Others experience temporary vision loss.
Nonvisual auras include motor weakness, speech or language abnormalities, dizziness, vertigo, and tingling or numbness (parasthesia) of the face, tongue, or extremities.
