We’ve all wished for it at one time or another. It may have been with your son who can’t sit still in school, your niece who was throwing a temper-tantrum, or a child who won’t stop crying on that red-eye flight. Wouldn’t it be nice to pull out a tranquiliser dart and poof … turn that little Tasmanian devil into a calm, quiet, sleeping beauty!?
The idea of that is not far from reality. Tranquiliser darts often contain antipsychotic drugs and there is a growing trend to prescribe these to our children.
From 1993 to 2002, the number of office based visits that included an antipsychotic drug increased more than 500% (Ed. in the U.S.)
As a parent desperate for answers, reaching for a quick fix pill can be understandably tempting. But what is the cost of doing so?
Adult Side Effects of Antipsychotic Drugs
Our collective focus on the quick fix makes it easy to ignore the long-term considerations around such an intervention. We have vast amounts of data showing that antipsychotic drugs cause high blood sugar, excess fat accumulation around the waist, low levels of good cholesterol (HDL), high levels of triglycerides, and increased blood pressure in adults.
Having three out of these five risk factors means that you have something called the metabolic syndrome.
Basically, this is a fancy term that means you are at an increased risk of developing diabetes, heart disease and stroke.
Longitudinal studies have shown that up to 52.4% of schizophrenic patients who start an antipsychotic drug will develop metabolic syndrome within the first three months of treatment. Pretty scary stuff.
However, the vast majority of this data comes from studies done on adults, and we’re here to talk about using these drugs on our children. Surprisingly, even though they are being used more and more in our youth, we don’t have a lot of data to see what the long-term consequences will be. Do antipsychotic drugs predispose our children to the metabolic syndrome just like adults? Or are they somehow protected from these deleterious effects?
Recent Study Sheds Light
A recent study helps us to further understand these questions. Children between the ages of six and eighteen were randomised into three groups. Each group was given one of the following ‘second-generation’ antipsychotic drugs: olanzapine, risperidone or aripiprazole. All subjects had behaviour problems and at least one had a psychiatric diagnosis such as ADHD. None of the children had ever taken antipsychotic drugs before.
At the conclusion of the twelve-week study, all three groups showed behavioural change. However, all three groups also showed significant negative side effects. Subjects showed an increased resistance to insulin, putting them at higher risk for early onset diabetes. They also showed an increase in body fat with specific increases deep within the abdomen around the organs.
Fat is Fat … Right?
One of the fascinating developments in our understanding of chronic disease is that the anatomical distribution of fat matters. To sum up a still developing story, fat distributed in the abdomen around the organs (visceral fat) is much more dangerous than fat just below the skin (subcutaneous fat). Thus, two people with the same amount of body fat may have very different health risks based on where their fat is stored.
In short, excess body fat is a risk factor for disease, but if that fat is distributed in the visceral region, it confers an additional independent risk for cardiovascular disease, diabetes, certain cancers, high blood pressure and abnormal cholesterol.
More disturbingly, researchers hypothesised that their study “likely underestimates longer-term treatment effects” because these negative changes are often progressive over the first year of treatment.
For those of you who don’t like maths, what they’re saying is that they only looked at the score in the first quarter, not at the end of the game. The real long-term risks of obesity, diabetes, cardiovascular disease, are probably much greater than those detailed in this short three month study.
Further, children are “physically and emotionally more vulnerable to the adverse effects (of antipsychotic drugs) because of their smaller size, developing physiology, and negative impact on peer perceptions.
To answer our previous question, children are not more resilient to the adverse effects of antipsychotic drugs, they are more susceptible.
Although alarming, these results are not particularly shocking. They confirm that what is bad for adults is also bad for youth … actually worse.
Why are These Drugs Given to Children in the First Place?
In the paediatric population, the majority of antipsychotic drugs are actually not given to treat psychosis, as the name implies. Surprisingly, they are generally prescribed to treat behavioural disorders. For example, only 2.8% of the subjects in this study actually had symptoms consistent with psychosis (some further percentage of whom were likely already treated with a stimulant known to induce psychosis). The remaining 97.2% had behavioural symptoms deemed unacceptable by school, family, or both.
The use of antipsychotic drugs in this manner is largely not approved by the FDA due to “insufficient evidence of safety and efficacy.”
So why is there a growing trend to prescribe them when they are not approved by the FDA and studies are mounting showing severe negative side effects?
Do We Really Practice Evidence Based Medicine?
Robert Whitaker, a medical journalist and author, writes that the field of psychiatry is experiencing an institutionalised form of cognitive dissonance – a conflicted psychological state that occurs when new information challenges deeply held beliefs.
In the context of this article, long held beliefs about the safety and efficacy of antipsychotic drugs are being challenged by new data showing their dangerous side effects and overall ineffectiveness. In general, people resolve this conflicted state “by sifting through information in ways that protect their self-esteem and their financial interests.”
Psychiatry, as an institution, is doing just that. Sifting through data to suit their needs. Research that shows psychiatric drugs in a negative light often gets swept under the rug as being biased, of poor quality or otherwise uninformed. There is little acceptance for anything that goes against that status quo. The goal is no longer to seek better treatment protocols, but to protect the power, prestige and financial interests of the psychiatric institution. Unfortunately, in this state, evidence based medicine cannot be practised.
As Upton Sinclair famously stated, “It is difficult to get a man to understand something, when his salary depends on his not understanding it.”
