UK Channel 4 programme on ADHD claims it is all a myth, it seems (I have only read a review in the Grauniad.)
My old college friend Iona Heath says it is certainly not a medical condition in her view. Anyone can have the symptoms.
The main argument against seems to be that MRI scans are normal - familiar?
But the reality is perhaps suggested by a recent meta-analysis of GWAS studies. For ADHD based on a doctor's diagnosis there are clear peaks on the Manhattan plots and heritability is estimated at 74%. For ADHD symptoms alone there are still some peaks but they do not reach significance - suggesting dilution.
So it looks as if ADHD is a real biomedical phenomenon but may require careful diagnosis - familiar?
