Current Primary Outcome Measures ICMJE |
Change From Baseline Hamilton Rating Scale for Depression 24-Item Scale to Study Completion (8 Weeks) [ Time Frame: Change from Baseline to 8 Weeks ] The Hamilton Rating Scale for Depression (HRSD) is a 24-item questionnaire used as an indication of depression and a guide to evaluate recovery. Total scores range from 0-74, not including atypical symptoms sub-scale. A score of 16 or above is typically considered to indicate the presence of depressive symptoms. Higher scores indicate greater severity. Because the full sample was not enrolled and the results are considered unreliable, no statistical analysis was performed other than calculating means and standard deviations.

Original Primary Outcome Measures ICMJE |
Hamilton Depression Rating Scale (HAM-D) [ Time Frame: 8 Weeks ] A multiple item questionnaire used to provide an indication of depression, and as a guide to evaluate recovery. Our target is depressive symptomatology as measured by the HAM-D.

Brief Title ICMJE | L-DOPA vs. Placebo for Depression and Psychomotor Slowing in Older Adults | ||||||
Official Title ICMJE | Targeting Dopaminergic Mechanisms of Slowing to Improve Late Life Depression | ||||||
Brief Summary | Individuals with Late Life Depression (LLD) often have cognitive problems, particularly problems with memory, attention, and problem solving, all of which contribute to antidepressant non-response. Our group and others have shown that decreased thinking speed is the central cause of functional problems in patients with LLD. Similarly, decreased walking speed is associated with depression and carries additional risk for falls, hospitalization, and death. Available evidence suggests that declining functionality in the brain's dopamine system contributes to age-related cognitive and motor slowing. The central hypothesis of this study is that by enhancing dopamine functioning in the brain and improving cognitive and motor slowing, administration of carbidopa/levodopa (L-DOPA) will improve depressive symptoms in older adults. | ||||||
Detailed Description | Enrolled participants were aged 60 and older with (1) a DSM 5 depressive disorder, (2) significant depressive symptoms, and (3) decreased thinking or walking speed will receive 8 weeks of treatment with L-DOPA up to 450mg. We will test whether L-DOPA increases brain dopamine release using neuroimaging and whether it speeds up thinking and walking speed. Data collected in the proposed studies may help identify a new treatment for LLD, which could have large public health ramifications given the prevalence, frequent treatment resistance, and chronicity characteristic of LLD. This project also will elucidate the neurobiology of slowing at molecular, structural, and functional levels of analysis, increasing our understanding of the interplay between these aging-associated processes and the pathophysiologic changes underlying late life neuropsychiatric disorders. Exploring patient characteristics that predict response to L-DOPA may provide useful information to guide differential therapeutics and develop personalized medicine for LLD. | ||||||
