Hoping you lot of experienced and wonderful mumsnetters can help me..
I have an 11 year old son with ADHD (and dyslexia). Was diagnosed in 2007 - all the usual problems, hyperactivity, attention span of literally seconds, inappropriate behaviour, no impulse control, sleep and eating issues etc etc.. the list goes on. It's pretty exhausting to be honest
And getting worse/more apparent as he gets older. He's also dyslexic, but that is a side issue to the ADHD. He's not currently on ADHD medication.. have tried everything and side effects vile... although may retry something soon.
We are currently in the process of going to tribunal to get a statement (using a solicitor) and also to re-consider his current school situation. Also getting more up to date EP and also OP and SALT reports (which we've not had done before).
He's currently in a mainstream comprehensive in year 7, but we are considering all options of private and specialist schools, but also keeping him at his current school with a statement/TA support etc. Don't really know what to do to for the best... 2 local private schools (one of which specialises in dyslexia) have both said they don't think they 'can meet his needs'.. 
Does anyone have any recommendations of specialist ADHD schools in London/Kent/Sussex or experience of this situation?
Not sure if keeping him in mainstream education but getting support of a TA is the answer or finding the right school that can cope with him.
Your thoughts would be much appreciated. Many thanks
