Condition: Major Depressive Disorder · Sponsor: University of British Columbia
Background Adults over the age of 60 with symptoms of major depressive disorder are said to have late-life depression (LLD), a condition that usually decreases a person's quality of life and is associated with other risks like physical frailty and dementia. A common feature of more severe LLD is psychomotor slowing, where a person's ability to think and move are impaired. For example, they might not be able to walk or process information as quickly, and they might have problems with their working memory. Psychomotor slowing in LLD might be the result of a problem with the way a person's body produces or responds to the neurotransmitter dopamine. The drug Levodopa (L-DOPA), which can replace missing dopamine in the brain, has been used to treat to treat Parkinson's disease for many decades, and it might also affect psychomotor slowing in LLD. Methods In this study, participants are adults aged 60 years or older with moderate to severe major depression. Participants undergo the "L-DOPA challenge"-a 2-week period where they receive a dose of L-DOPA once a day for the first week and a dose of L-DOPA twice a day for the second week. Before and after a participant completes the L-DOPA challenge, the study team assesses their depressive symptoms and psychomotor function. After the L-DOPA challenge, if a participant still shows signs of moderate or severe depression, they receive an antidepressant for 12 weeks. Aims The first aim of this study is to test the feasibility of the …
