BACKGROUND
A high-risk subgroup of older patients with depression has slowed processing and gait speeds. This study examined whether carbidopa/levodopa (L-DOPA) monotherapy increased dopamine availability, increased processing/gait speed, and relieved depressive symptoms.
METHODS
Adult outpatients with depression >59 years old underwent baseline [
RESULTS
Thirty-six subjects participated (age, 75.3 ± 7.5 years; 44.4% male). Significant, dose-dependent increases in processing and gait speed were observed with L-DOPA (450-mg dose: processing speed factor score effect size = 0.41, p = .001; dual-task gait speed effect size = 0.43, p = .002). [
CONCLUSIONS
By enhancing availability of dopamine, L-DOPA improved processing and gait speed in older adults with depression and significantly decreased [
