Evaluative Conditioning: A Brief Cognitive Intervention Aimed to Modify Addiction Behaviour of Alcohol-dependent Patients
The study assesses whether adding a behavioral intervention, known as the Adolescent Community Reinforcement Approach (A-CRA), to the treatment of individuals already receiving buprenorphine/naloxone can improve treatment success and retention rates in young adults with severe opioid use disorder.
In this study, the investigators are looking at how people make decisions about reward-related items, both monetary and food related after taking either the dopamine agonist bromocriptine or the COMT inhibitor tolcapone, in healthy control subjects. Subjects will fill self-report questionnaires and undergo an MRI scan.
This is an open label randomized controlled trial, comparing two modes of treatment for internet addiction (gaming or gambling online) with sleep disorders associated.
This is a multicenter, interventional, randomized study for preventive and therapeutic strategies for patients with head and neck or Lung cancer; contribution of an addiction support
Background: - Varenicline (Chantix ) is a drug that is approved by the Food and Drug Administration (FDA) to help people stop smoking. Varenicline is very effective in helping some people quit smoking, but is less effective for others. Researchers are interested in conducting more in-depth studies into how varenicline works, including its effect on smokers' responses to items that may trigger cigarette cravings, in order to develop better smoking cessation medications. Objectives: - To examine the effectiveness of varenicline as an effective medication for tobacco addiction by studying its effect on nicotine reinforcement, nicotine-seeking behavior, cue-elicited craving, and performance impairment and craving after overnight tobacco deprivation. Eligibility: - Individuals between 18 and 50 years of age who have been smoking at least 10 cigarettes per day for at least 2 years. Design: - This study will require 12 study visits. Some visits will be brief and other visits that involve test sessions will last up to 8 hours. If no sessions are repeated, the study will take 26 days. Participants will not be required to attempt to quit smoking during this study. - Participants will be screened with a full physical examination and medical history, blood and urine tests, and other tests as required by the study researchers. - Participants will take two sets of pills during the study: the first set during the first 12 days of the study, followed by a 2-day break, then the second set during the last 12 days. Some of the pills will contain varenicline, and others will be placebos. - On Day 1 of the study, participants will come to the National Institute on Drug Abuse to receive the first set of pills. Participants will take the first pill before leaving. - On Day 8, participants will have a training session that will measure the amount of carbon monoxide in the breath. Participants will also complete several questionnaires about smoking habits and current mood, and will have a chance to practice the procedures they will do in the study. - On Days 9 and 10, participants will have behavioral test sessions that will last 7 to 8 hours. Day 9 will involve tests of cue response to items that may trigger cigarette cravings, and tests of general nicotine cravings over several hours. Day 10 will involve tests of general nicotine cravings over several hours, and then tests of nicotine-seeking behavior. Participants will be provided with lunch during these all-day sessions. - On Day 11, participants will have memory and attention tests, and will provide a blood sample. Participants will not be allowed to smoke for 12 hours before the start of the next test on Day 12. - On Day 12, participants will provide a breath sample, and will have two sets of memory and attention tests before they will be permitted to start smoking again. There will be no tests on Days 13 and 14. - Starting on Day 15, participants will repeat the schedule of tests from Days 1 through 12 with the second set of pills.
Substance-using adults are admitted to hospital for medical complication from their drug and alcohol use at very high rates; yet, their care is often defined by low rates of referral to addiction treatment programs and recidivism. In 1997, we instituted an integrated medical-substance use treatment program at Johns Hopkins, the First Step Day Hospital, designed for intensive post-acute care of previously hospitalized substance using adults. We have shown that patients with dual diagnoses admitted to First Step more often complete their course of medical care and stay in recovery longer than patients not admitted to First Step.(1;2) On discharge from First Step, patients are medically stable and drug-free. Their substance abuse care is transferred to an out-patient substance abuse treatment facility and their medical care is transferred to their primary care provider. Unfortunately, many patients are lost to follow-up during this transition. We believe that a peer mentor-based disease management program (PM) can provide continuity of care that begins in First Step and continues after discharge thereby increasing the proportion of patients who remain in treatment for their addiction and medical conditions. Peer mentors are persons from the target community who have been in recovery for 5 or more years. In cooperation with patients and providers, peer mentors improve the integration of care, quality of care, and access to healthcare services. This pilot study will test the effectiveness of a peer mentor-based disease management program. The specific aims are to compare the impact of the PM intervention verses enhanced usual care on outcomes in three domains (1) medical/psychiatric health status, (2) addiction recovery, and (3) social resource acquisition. If successful, this study will provide evidence supporting a larger randomized controlled trial of the impact of field workers on post-acute care among patients with dual diagnoses.
Background: - Brain imaging studies, genetic research, and investigations of stress have provided more information about the role of dopamine in processing reward and punishment, and in vulnerability to substance dependence. Researchers are interested in learning more about how the brain responds to rewards, including drugs of abuse, and how these responses may involve genetic factors or previous stressful events. - Researchers intend to use the drug amphetamine to increase levels of dopamine in the brain and study the effects through two kinds of scanning: functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). Objectives: - To examine the relationship among dopamine function, brain activity, reward processing, genetic profile and exposure to stress in normal healthy adults. - To examine the variation in these factors between normal healthy adults and individuals with current cocaine-dependence. Eligibility: - Individuals 18 to 45 years of age who are either current cocaine users or healthy volunteers with no history of substance abuse or dependence. Design: - The study will consist of an initial evaluation session and six study visits, four of which will involve fMRI scans (3 hours each) and two of which will involve PET scans (8 to 9 hours each). - Cocaine-using participants will enter the inpatient clinical research ward at the National Institute on Drug Abuse Addiction Research Center the night before each scanning session and will be discharged the following day. Healthy volunteer subjects will not be required to stay overnight and will arrive as outpatients for the PET session. Participants will not be released until researchers have determined that participants are not experiencing significant effects of the drug. - Initial session (1): Participants will complete questionnaires about past reactions to stressful situations, and will be trained to do thinking tasks that will be performed in fMRI visits. The tasks will be practiced in a mockup of an MRI machine. - MRI sessions (2-5): Participants will receive either oral amphetamine or a placebo, and will perform thinking, short-term memory, and reward tasks during MRI scanning as directed by researchers. - PET sessions (6-8): Participants will receive either oral amphetamine or a placebo, and will provide blood samples during the PET scanning sessions. Participants will have short breaks during the PET scanning sessions.
The purpose of this research study is to determine whether Carvedilol, an FDA approved beta blocker, when administered for an 8-week period to veterans currently undergoing treatment for methamphetamine dependence (1) improves their ability to stay in treatment longer, (2)eases the aversive symptoms that accompany stimulant withdrawal, and (3) increases the time they remain abstinent from methamphetamine.
