An unstable, staggering manner of standing and walking. Patients do not generally injure themselves from this condition, as they only appear to fall when a person or soft object is within range to catch them.
Example: The patient reels about the room in a dramatic manner. He seems constantly on the verge of falling, but always saves himself.
