5 Clinical Trials for Various Conditions
Recent research has shown that some individuals become addicted to or dependent on caffeine and are unable to quit or reduce caffeine consumption despite a persistent desire to do so. The aims of the current study are to characterize caffeine use among individuals with physical or psychological dependence on caffeine and evaluate a manual-based intervention to promote caffeine reduction and cessation.
Recent research has established that some individuals report that they are unable to cease caffeine use, despite feeling that caffeine is posing a health risk or causing significant impairment in their daily activities. Despite the high rates of unsuccessful efforts to cease or control caffeine use in the population, there has been little research on the parameters of successful caffeine reduction and no research on caffeine cessation. The goals of the study are as follows: 1. evaluate the applicability of DSM-IV dependence criteria for self-reported problematic caffeine use. 2. evaluate characteristics (e.g, co-morbid psychopathology) of individuals who report that they have had difficulty quitting caffeine use on their own and who are seeking treatment for caffeine use. 3. test the efficacy of a caffeine reduction treatment administered to individuals who would like to quit/reduce caffeine use, but have found it difficult to do so in the past.
The purpose of this online research study is to determine whether or not a gradual caffeine reduction program developed at Johns Hopkins can help people reduce their caffeine use. The investigators will provide materials to help guide caffeine reduction and ask questions to track caffeine use over several weeks. The investigators will also assess how reducing caffeine may benefit common caffeine-related problems such as anxiety, sleep disturbances, and gastrointestinal distress. The study will also determine whether or not people like participating in this caffeine reduction program in an online format.
The ongoing opioid epidemic is a public health crisis, and surgical patients are particularly vulnerable to opioid-dependency and related risks. Emerging data suggest that caffeine may reduce pain after surgery. Thus, the purpose of this study is to test whether caffeine reduces pain and opioid requirements after surgery. The investigators will also test whether caffeine improves mood and brain function (e.g., learning, memory) after surgery.
This study is being done to find out if medicines that affect a neurotransmitter (chemical messenger) in the brain called adenosine improve behavioral problems that are related to drug abuse. Another purpose of the study is to find out how genes related to adenosine change how people respond to these medicines. More information about how these medicines change behaviors may be helpful to come up with new treatments for drug abuse.
