This invention relates to a method of predicting the activity of a CNS drug on striatal dopamine transporter populations. The method uses SPECT brain imaging to predict the activity of antidepressants or anxiolytic agents on striatal dopamine transporter populations. The method uses the increase in dopamine transporter populations as a marker for predicting sexual dysfunction side effects, as well as to determine proper dosing for antidepressants or anxiolytics agents in order to avoid the sexual dysfunction side effects.
