I am a retired psychotherapist
There is no research that says medication works for ADHD. medication is developed for big Pharma not the individual. The medication is awful. I have seen the disasterous and debilitating effects on children. Who, in my opinion do not need a tranquiliser at 10 years old. They need better parenting.
In the early 1990's ADHD was quite rare. Amazingly as soon as one child was diagnsed with ADHD suddenly there was an increase in Parents taking their children to the GP for diagnosis. It seems that the diagnosis was spread by parents standing outside the school gates with nothing better to do.
Children are inherently naughty, messy. dishevelled, argumentative, and generally annying but this does not mean they need a medicated cosh to keep then under parental control.
The symptoms of ADHD are experienced by 100% of the human population.
