What this trial studies

This clinical study evaluates the impact of extended-release caffeine compared to immediate-release caffeine on mood states, alertness, and cognitive performance following a night of inadequate sleep. It employs a double-blind, randomized, crossover design with 36 healthy participants from the Tampa Bay Area, who will undergo two laboratory visits after a minimum 10-hour fast and a night of sleep deprivation. Participants will be assessed using various cognitive and mood evaluation tools to determine the efficacy and side effect profiles of the caffeine formulations.

Who should consider this trial

Good fit: Ideal candidates are healthy men and women aged 35-50 who are moderate caffeine consumers and have an intermediate chronotype.

Not a fit: Patients with a history of anxiety or sleep disorders, smokers, or those who consume alcohol or sleep medications prior to the study may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into how different caffeine formulations can enhance cognitive function and mood in individuals experiencing sleep deprivation.

How similar studies have performed: While there have been studies on caffeine effects, this specific approach comparing extended-release and immediate-release formulations in a sleep-deprived context is relatively novel.
