I do not doubt that an observant, thorough, and experienced physician may correctly diagnose attention-deficit/hyperactivity disorder in a very young child. It takes, I suspect, some additional courage to prescribe psychotropic medication for that child. Can Rapley et al1 provide any information on what types of physicians (eg, pediatricians, family practitioners, general psychiatrists, or child psychiatrists) made that diagnosis and started pharmacotherapy?
