Attention Deficit Hyperactivity Disorder, commonly known as ADHD, has become an epidemic. According to the Centres for Disease Control (CDC), ADHD is one of the most common neurodevelopmental disorders of childhood. It is usually first diagnosed in childhood and often lasts into adulthood. Children with ADHD may have trouble paying attention, controlling impulsive behaviours (may act without thinking about what the result will be), or be overly active.

They go on to state that it's normal for children to have trouble focusing and behaving at one time or another. "However, children with ADHD do not just grow out of these behaviours. The symptoms continue, can be severe, and can cause difficulty at school, at home, or with friends."

The CDC claims that children with ADHD might daydream a lot, forget or lose things a lot, squirm or fidget, talk too much, have a hard time resisting temptation, have trouble taking turns, and make carless mistakes or take unnecessary risks. But are these really symptoms of a serious "neurodevelopmental disorder?"

Is This Science-Based?

It's not as if children are taken into the lab and have their brains scanned to determine if serious brain abnormalities exist. ADHD is diagnosed purely off of behaviour, and there may be something very wrong with diagnosing someone with neurological abnormalities simply baed on observation, instead of actual science. Who is to say that the behaviours listed above are not those of a normal child, or even a normal adult, especially within a school or work environment that does not seem to be foster a human being's natural state? Perhaps the person or child in question doesn't actually have neurodevelopmental problems, but is simply responding appropriately to the environmental that they find themselves in?

There is hardly any evidence suggesting that there is a neurological problem, as is often expressed by the medical industry. There are studies, however, that do show differences. For example, one of the largest imaging studies of ADHD to date recently identified differences in five regions of the brain, with the greatest differences seen in children rather than adults.

It's important to note here the the brain of a child is still developing, and that the structure is not permanent and continues to develop until early adulthood. More than 3,000 people diagnosed with ADHD had an MRI compared to controls, to measure the volume and the size of seven regions of the brain that were thought to be linked to ADHD-the pallidum, thalamus, caudate nucleus, putamen, nucleus accumbens, amygdala, and hippocampus. The study found that overall brain volume and five of the regional volumes were smaller in people with ADHD — the caudate nucleus, putamen, nucleus accumbens, amygdala and hippocampus.
"These differences are very small — in the range of a few percent — so the unprecedented size of our study was crucial to help identify these. Similar differences in brain volume are also seen in other psychiatric disorders, especially major depressive disorders."- Dr Martine Hoogman, Radboud University Medical Center, Nijmegen, The Netherlands.(source)
Smaller brain regions do not equate to a neurodevelopmental disorder or a lack of brain functioning though. This is simply an assumption. As with depression, where 6 decades of research that serotonin (or norepinephrine, or dopamine) deficiency is the cause of depression and anxiety, scientific credibility has not been achieved. This is well known. A New England Journal of Medicine review on major depression stated:
" ... numerous studies of norepinephrine and serotonin metabolites in plasma, urine, and cerebrospinal fluid as well as postmortem studies of the brains of patients with depression, have yet to identify the purported deficiency reliably."
Despite this fact, drugs are being prescribed that alter brain chemistry based on the prevailing unsubstantiated 'theories' regarding several 'mental disorders.' Here is an eye opening quote regarding the Diagnostic and Statistical Manual of Mental Disorders:
"[DSM-V] is a wholesale imperial medicalization of normality that will trivialize mental disorder and lead to a deluge of unneeded medication treatment - a bonanza for the pharmaceutical industry but at a huge cost to the new false positive patients caught in the excessively wide DSM-V net."-Allen Frances, DSMIV Taskforce Chair (source)
Financial Ties With Big Pharma

Speaking of the DSM, American psychologist Lisa Cosgrove and researchers have investigated financial ties between the DSM panel members and the pharmaceutical industry. She published her research in the journal Plos One. The study found that, of the 170 DSM members who sat on panels of 'mood disorders,' 'schizophrenia' and other psychotic disorders, most of them had financial ties to drug companies. The connections were especially strong in those diagnostic areas where drugs are the first line of treatment for mental disorders:
The revised Diagnostic and Statistical Manual of Mental Disorders (DSM), scheduled for publication in May 2013 by the American Psychiatric Association (APA), has created a firestorm of controversy because of questions about undue industry influence. Some have questioned whether the inclusion of new disorders (e.g., Attenuated Psychotic Risk Syndrome) and widening of the boundaries of current disorders (e.g., Adjustment Disorder Related to Bereavement) reflects corporate interests. These concerns have been raised because the nomenclature, criteria, and standardization of psychiatric disorders codified in the DSM have a large public impact in a diverse set of areas ranging from insurance claims to jurisprudence. Moreover, through its relationship to the International Classification of Diseases, the system used for classification by many countries around the world, the DSM has a global reach.
Psychiatrist Dr. Daniel Carlat has said:
"And where there is a scientific vacuum, drug companies are happy to insert a marketing message and call it science. As a result, psychiatry has become a proving ground for outrageous manipulations of science in the service of profit."
Questioning The System

Dr. Marcia Angell, a physician and longtime Editor-in-Chief of the New England Medical Journal (NEMJ), also considered one of the most prestigious peer-reviewed medical journals in the world, said the following:
It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgment of trusted physicians or authoritative medical guidelines. I take no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades as an editor of The New England Journal of Medicine. (source)
Here is another great quote:
"The medical profession is being bought by the pharmaceutical industry, not only in terms of the practice of medicine, but also in terms of teaching and research. The academic institutions of this country are allowing themselves to be the paid agents of the pharmaceutical industry. I think it's disgraceful."-Arnold Seymour Relman (1923-2014), Harvard professor of medicine and former Editor-in-Chief of The New England Medical Journal (source)
