New data has shown that UK prescriptions for Ritalin and other similar Attention deficit hyperactivity disorder (ADHD) medications have more than doubled in the last decade, from 3,59,100 in 2004 to 9,22,200 last year.
It generates pharmaceutical sales worth $9 billion per year. However there is no evidence to prove that ADHD is a genuine illness.
"There is no robust evidence to demonstrate that what we call ADHD correlates with any known biological or neurological abnormality," Sami Timimi, child psychiatrist at Lincolnshire NHS Trust.
According to Timimi, the hyperactivity, inattentiveness and lack of impulse control that are at the heart of an ADHD diagnosis are simply a col collection of behaviors.
Anyone who claims that a behavior is being caused by ADHD is perpetrating a philosophical tautology. That person is doing nothing more than telling you that hyperactivity is caused by an alternative name for hyperactivity.
There is still no diagnostic test - no marker in the body - that can identify a person with ADHD. The results of more than 40 brain scan studies are described by Timimi as "consistently inconsistent". No conclusive pattern in brain activity had been found to explain or identify ADHD.
