Age is significant factor in getting an ADHD ‘diagnosis’

by on January 23, 2017 in ADHD

The Guardian reports on another study showing that the youngest children in a group are more likely to get an ADHD diagnosis.

This makes at least 4 studies which have come to the same result. The others are:

The significance of these studies is that they provide ‘clinical’ proof for what is theoretically obvious. Given that ‘ADHD’ is a category of psychiatry, whose diagnosis is determined by a whole range of subjective factors (whims of parents, management needs of teachers etc.) it is inevitable that diagnoses will be skewed. It is an indication of the power or money (and the compliance with corporate money of the media) that these studies get relatively little coverage whereas studies promoting small causal genetic links get vast amounts of coverage. That’s because the latter support the profitable ADHD drugging scam whereas these ones do not.
