My 8 yr old step daughter has Aspergers,on a regular basis she walks up and down the room with one fist clenched and in a state of trance unaware of her surroundings. When asked why she does this she said it helps her de stress. I've searched the internet and have come across Stimming/absence seizures, the paediatrician has never heard of this and is basically not interested. Other people have said its a coping mechanism although I'm not convinced. Has anyone else experienced this or anything similar? I'm very worried as it's getting worse and nobody seems interested
