Outcome Measures
Primary Outcomes (1)
Change in Hamilton Depression Rating Scale (HAM-D) Scores
Change in Hamilton Rating Scale for Depression over 12 weeks. Hamilton Depression Rating Scale ranges from 0-50. Higher scores represent more significant depression. Mild depression ranges from 8-13, moderate depression from 14-18, severe 19-22 and very severe any score over 23.
from the beginning (0 weeks) to end (12 weeks) of the double-blind phase
Secondary Outcomes (16)
Change in Montgomery-Asberg Depression Rating Scale (MADRS)
from the beginning (0 weeks) to end (12 weeks) of the double-blind phase
Change in Beck Depression Inventory II (BDI-II)
from the beginning (0 weeks) to end (12 weeks) of the double-blind phase
Change in Geriatric Depression Rating Scale (GDS)
from the beginning (0 weeks) to end (12 weeks) of the double-blind phase
Change in Brief Psychiatric Rating Scale (BPRS)
from the beginning (0 weeks) to end (12 weeks) of the double-blind phase
Change in Unified Parkinson's Disease Rating Scale (UPDRS)
from the beginning (0 weeks) to end (12 weeks) of the double-blind phase

Study Arms (3)
paroxetine
ACTIVE COMPARATORParoxetine and venlafaxine will be compared to placebo over 12 weeks.
venlafaxine extended release
ACTIVE COMPARATORParoxetine and venlafaxine will be compared to placebo over 12 weeks.
placebo
PLACEBO COMPARATORParoxetine and venlafaxine will be compared to placebo over 12 weeks.
Interventions
Paroxetine 10 mg tablets or matching placebo given once a day for the first two weeks. If depression is not being effectively treated then the paroxetine or matching placebo will be increased to 20 mg, followed by a 10 mg increase every two weeks (if tolerated). Dosage for this study will not exceed 40 mg.
Venlafaxine XR 37.5 mg capsules or matching placebo given once a day for the first two weeks. If depression is not being effectively treated then the venlafaxine XR capsules or matching placebo will be increased to 75 mg followed by 75 mg increments every 2 weeks (if tolerated). Dosage for this study will not exceed 225 mg.
