Re: Cardiovascular safety of central nervous system stimulants in children and adolescents: population based cohort study
This article interested me. I've felt concern over dopaminergic medications in children ever since knowing a childhood friend who was given Ritalin fall into drug dependency.
Some principles seem well established:
Firstly, Dopaminergic agents can promote affective disorders, by hijacking the 'seeking' system (1).
Secondly, there is a scarcity of safety data for methylphenidate looking at social and psychiatric consequences beyond 2 years (2).
Thirdly, Methylphenidate shares pharmacodynamic porperties with cocaine, but is ameliorated by its longer duration of action. Like cocaine, methyphenidate is also a drug of abuse (3).
Fourthly, exposure to one drug of abuse will prime a person for abuse of other drugs, creating a vulnerability which may persist for years and may lead to relapse.
Lastly, many people first experiment with hedonic drugs in their teens.
We then induce a conclusion: that giving children dopaminergic drugs risks promoting addictive, high seeking behaviour in later life?
Who will fund that one?
