Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Change score in thalamic [123I]FP-CIT binding ratio between SPECT scan 1 and 2 (i.e. SERT occupancy), and the interaction effect with citalopram dose. 2. Change score in thalamic CBF (phMRI study). This is the difference between baseline CBF and post-citalopram CBF scores. The interaction effect of delta CBF scores and citalopram dose will also be assessed. Endpoint: association between SERT occupancy and delta CBF. | — |
