I just saw a very short clip of breakfast television in which a young lady sufferer of ADHD, narrated how she had to be held down by three adults after going berzerk in her living room. Another family member had captured the incident on mobile phone and we were treated to a recording of these events. The girl then explained how she had felt, her mind seemingly full of rage and violence, yet she could not explain it - "all I was doing was watching television".
The actual story being covered is that children who have been treated for Attention Deficit Hyperactivty Disorder with prescribed medication have not in fact benefitted over a longer period of time, if at all. It seems that in fact their growth may be stunted.
