About ten days ago I noticed that she has started to nod her head up and down, rhythmically, constantly, and very slightly, when she's sitting up. At the same time, she has begun to roll her lips and, after each roll, slightly protrude her tongue. These movements are involuntary and she says she isn't aware of them. Her PCP is scheduling an appointment with a neurologist. Has anyone else seen this in an otherwise healthy parent, and what should I expect to happen next? .
