Neurocognitive Dysfunction clinical trials at UC Health
3 in progress, 2 open to new patients
open to eligible people ages 18 years and up
Decreased blood flow to the brain can cause decreased cognitive function. Carotid disease can result in decreased blood flow to the brain. The investigators seek to assess this relationship prospectively through performing a battery of neurocognitive assessments, collection of serum markers of inflammation, and through neuroimaging at two points before intervention (2 months and 1 month before stenting) and at two points after intervention (1 month and 2 months after intervention). The goal is to provide prospective evidence to identify the extent to which carotid stenosis and hypoperfusion of the brain results in diminished neurocognitive performance, and see if serum biomarkers before and after stenting correlate with these findings.
open to eligible people ages 18-65
Low oxygen at altitude causes pauses in breathing during sleep, called central sleep apnea. Central sleep apnea causes repeated awakenings and poor sleep. Low oxygen itself and the induced oxidative stress can damage mental function which is likely worsened by poor sleep. Reduced mental function due to low oxygen can pose a serious danger to mountain climbers. However there is also mounting evidence that even in populations of people that live at high altitudes and are considered adapted, low oxygen contributes to reductions in learning and memory. Therefore there is a serious need for treatments which may improve sleep, control of breathing and mental function during low oxygen. Melatonin is a hormone produced in the brain during the night which regulates sleep patterns with strong antioxidant and anti-inflammatory properties. A study previously reported that melatonin taken 90 mins before bed at 4,300 m (14,200 ft) induced sleep earlier, reduced awakenings and improved mental performance the following day. However how melatonin caused these effects was not determined. Therefore this study aims to determine how melatonin effects control of breathing, sleep and mental performance during exposure to low oxygen.

The objective of this proposal is to advance medication development for alcohol use disorder by examining the efficacy and mechanisms of action of minocycline, a neuroimmune modulator, as a potential treatment. This study has important clinical implications, as the available treatments for alcohol use disorder are only modestly effective and testing novel medications is a high research priority.
