Abstract
Dysregulations in monoaminergic systems have been implicated in attention deficit/hyperactivity disorder. The spontaneous hypertensive rats (SHR) are used as an animal model for ADHD. Juvenile SHR rats exhibited low dopamine transporter (DAT) density, low vesicular monoamine transporter 2 (VMAT2) density and lower unstimulated dopamine (DA) release in comparison to their corresponding WKY controls. Chronic methylphenidate treatment of the young SHR rats was associated with lower DAT density and lower unstimulated basal dopamine release but with enhanced potassium- and amphetamine-induced dopamine release. These neurochemical alterations might be relevant to the pathophysiology and to the beneficial effect of methylphenidate in ADHD.
