Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Difference of AMPA receptor density in the brain between the panic disorder patients and healthy controls (obtained in other studies) | — |
Secondary
| Measure | Time frame |
|---|---|
| 1) Correlation between AMPA receptor density in the brain and clinical measurements in patients with panic disorder. 2) Correlation between functional connectivity and AMPA receptor density in the brain regions composing the connections where connectivity differed from healthy controls; Association between fALFF values and AMPA receptor density in brain regions where fALFF values differed from healthy controls. | — |
