The striatal dopaminergic innervation was investigated postmortem in 49 control and 57 parkinsonian brains by assessing the binding of tritiated alpha-dihydrotetrabenazine ([3H]TBZOH), a specific ligand of the vesicular monoamine transporter. The density of [3H]TBZOH binding sites in the caudate nucleus of control subjects decreased significantly with age, suggesting an age-dependent reduction in striatal dopamine innervation. In contrast, an increase with the age at time of death was observed… CONTINUE READING
