My 6 yr old daughter started having slight involuntary movement, jerking head side to side but now one week later she does it mult times an hour. She jerks head side to side very hard and quick, she nods head forward and backwards and both arms and legs jerk. None of the movements are in a rhythm or in a sequence. Her EEG was neg for seizures but her sleep study showed obstructive sleep apnea due to enlarged tonsils. We see a neurologist for our first visit 7/16/12......the sudden onset of all these moments have us worried sick. Obviously it looks likes Tics to me, they onset in the morning but get worse as the day goes on and its terrible in afternoon and at night then disappears in her sleep. She doesn't really do anything noticeable until she is with family at home, in other words anxiety doesn't bring it on. She sniffs alot to.....so vocal and motor tics right? Why all of a sudden the explosion of tics when a few weeks ago she was fine without any problems. Could a virus last week followed by ear infection start this?
