Official title

Nicotinic Modulation of the Cognitive Control System in Late-Life Depression (R33 Phase)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Deficits in cognitive control are core features of late-life depression (LLD), contributing both to emotion dysregulation and problems with inhibiting irrelevant information, conflict detection, and working memory. Clinically characterized as executive dysfunction, these deficits are associated with poor response to antidepressants and higher levels of disability. Improvement of cognitive control network (CCN) dysfunction may benefit both mood and cognitive performance, however no current pharmacotherapy improves Cognitive Control Network deficits in LLD. The study examines the hypothesis that nicotine acetylcholine receptor agonists enhance Cognitive Control Network function. This effect may resultantly improve mood and cognitive performance in LLD. Small, open-label studies of transdermal nicotine (TDN) patches have supported potential clinical benefit and provided support that transdermal nicotine administration engages the Cognitive Control Network. This blinded study will expand past open-label trials supporting potential benefit in LLD. It will examine TDN's effect on depression severity and cognitive control functions measured by neuropsychological testing. The study will evaluate 60 eligible and enrolled participants over a 3-year period.
