Ds8 (who has high functioning autism) has developed a vocal tic which is a combination of throat clearing and harsh coughing and it is RELENTLESS. Very loud, every couple of seconds, constant noise. His voice is changing as well and I think he's creating some long term damage to his vocal folds. It's an awful noise that reminds me of lying next to someone who snores and not knowing when the next noise will come and flinching when it does. We all hate it. It upsets ds as he can't concentrate or watch tv as it's too noisy.
The advice is ignore. We're ignoring. It's getting worse....much worse actually. We've tried relaxation, distraction and getting him to do something else like sucking ice cubes (all without telling him why so it doesn't draw attention to it) and nothing is working. I'm most worried about long term damage really.
Anyone got experience?
