Filter by:Background: People with addictions often find it hard to choose the long-term benefits of abstinence over the short-term effects of using drugs. Researchers think this is partly due to parts of the brain involved in certain types of learning and decision-making. Researchers want to test these basic functions using a simple task with pictures and odors. Objective: To see if performance in a learning task differs between people who have opioid-use disorder and people who don t. Eligibility: Adults 21-60 years old who are willing to fast for at least 6 hours and smell food odors. Those with an opioid-use disorder must either not use for at least 3 weeks or be in treatment. Design: Participants will have 1 visit that will take up to 5 hours. Before the visit, participants will be asked to not eat or drink anything except water for at least 6 hours. At the visit, participants will be checked for signs of intoxication. Participants will give urine and breath samples. Participants will have tests of learning and behavior. They will look at shapes on a computer screen. The shapes will be paired with different food odors. The odors will come from a sterile tube placed under the nose. Participants will have their breathing monitored with a belt around the upper abdomen. About 30 days and 60 days later, participants will be called and asked about their drug use over the past 30 days. ...
Abuse of analgesics represents an important part of prescription drug abuse. The consequences in terms of morbidity and mortality at the population level could reach worryingly high levels, as illustrated by the US context. This issue should not focus only on opioid analgesics, but must also account for some antiepileptics or antidepressants with abuse potential (for example, pregabalin or gabapentin). In France, reports related to tramadol abuse are increasing, in particular since dextropropoxyphene withdrawal. Trends of growing abuse are also reported for other analgesics. Patients with no history of primary dependence constituted a significant proportion of those developing a tramadol abuse. There is therefore a need for early identification of these patients and to raise awareness of health professionals on this issue, in particular in primary care. Given the extensive use of analgesic drugs in France, the problem of primary dependence should not be neglected. Since it will affect people who have no history of drug abuse, strategies for identification and prevention are differing from a population already using psychotropic products for example.
The management of the craving is a key element in addiction treatment as the craving is linked to the probability of relapse. Several cues could induce the craving, some generic substance-induced cues or addictive behavior-related cues (e.g. gambling-related cues), and also some more subject-specific cues. The awareness of the craving intensity and its individual cues for each patient will allow the clinician to tailor a better treatment. The aim of this study is to evaluate the efficacy of a program based on an Individually Adjusted Therapy scale added to a treatment as usual for the treatment of addiction.
Craving arises in response to an affective tone that is associated with perceptual representations of a sensory object, rather than directly in response to the object. The investigators presume that qi gong functions to decouple pleasant and unpleasant experience from habitual reactions by removing the affective bias that fuels such emotional reactivity. Qi gong training may specifically target the associated learning process with an emphasis on the critical link between affect and craving in an addictive loop.
Background: Many smartphone apps intend to help people with addictions. But not enough is known about how they should work. Researchers want to study an app that gives people the advice they need, just when they need it. This is a JITAI. It stands for Just-In-Time Adaptive Intervention. To create a good JITAI, researchers need to know what approaches work best at different moments. Objective: To develop ways to treat addiction with a smartphone app. Eligibility: Adults ages 18-75 who use heroin or other opioids Design: Participants will be screened in another protocol. Participants will visit a Baltimore clinic 3 days a week to give urine and breath samples. Some participants will get their treatment at this clinic. Participants will answer questions about their personality and stress. Participants will randomly be assigned to the JITAI group or a comparison group. Participants will have a training session on using the smartphone app. JITAI participants will also watch a video about the written messages they ll see in the app. Weeks 3-10: participants will carry a smartphone. Four times a day, it will beep and ask questions. These will be about the participant s activities and mood. The JITAI group will see a short message after. The message is meant to be helpful. For the first 16 evenings, JITAI participants will get more information on the phone. Answers to the app s questions will be transferred automatically from the smartphone to secure computers at the NIH. During the last week, participants can choose the kind of messages they see. Week 11: participants will return the smartphone and answer questions. Weeks 12-16, participants who are getting their medicine from the research clinic will be encouraged to transfer to other clinics. Otherwise, they will have their dose slowly reduced to zero.
Patients over 65 years old who are exposed to alcohol or benzodiazepines will be recruited through the Fragility Assessment and Addictions Prevention Day Hospital, the Addiction Service and the Geriatric Post-Emergency Department. Toulouse University Hospital. The investigators will study descriptively the frequency of substance use disorder and the frequency of DSM-5 criteria associated with this diagnosis in a population of elderly subjects.
Our goal is to determine the representations of addiction among caregivers working in the field of mental health. We hypothesize that caregivers, despite their investment in care, have a negative social representation of patients suffering from addictive disorders, which could be related to a lack of training on the pathology and its social repercussions.
Cocaine abuse is associated with serious physical, psychiatric and social problems. Addiction results in the compulsive use of a substance with loss of control and persistence despite the negative consequences.The act of re-engaging in the search for drugs is called relapse and a particularly insidious aspect of addiction is that vulnerability to relapse lasts for many years after stopping drug use. The main reason why people continue to use cocaine is because of its influence on the reward system.Indeed, this substance makes it possible to increase the level of dopamine, particularly in the nucleus accumbens.This increase in dopamine is not related to the hedonic pleasure that consumption provides. Instead, it imprints a positive value to enhancers and facilitates the learning of reward associations through the modulation of the cortical and subcortical regions of the brain.In other words, it suggests that users become sensitive to a series of stimuli that combine with a rewarding feeling, which drives them to consume when they encounter them. N-acetylcysteine (NAC) has been used for a long time, mainly as mucolytic. It has also been used as a glutathione antioxidant precursor in the treatment of paracetamol overdose for more than 30 years. NAC has shown beneficial effects in animal models of cocaine addiction by reversing neuroplasticity and reducing the risk of restoring consumer behavior in rodents. Human studies show that NAC is potentially effective in preventing relapse in abstinent patients and ineffective in reducing current consumption. In this study the investigators will test a sample of newly detoxified (and therefore abstinent) patients who have taken a 3-4 week course of treatment, in order determine if NAC can be a useful medication candidate to avoid relapse in patients with cocaine dependence.
The main objective of this study is to assess the efficacy of bilateral deep brain stimulation (DBS) of the Nucleus Accumbens(NAc) as a novel treatment in severe methamphetamine addiction. Our hypothesis is that bilateral DBS of the NAc will significantly reduce the craving for methamphetamine.
Background: Cocaine use disorders (CUD) is a complex brain disorder, involving several brain areas and neurocircuits. Effective treatments for CUD are still needed. Repetitive transcranial magnetic stimulation (rTMS) stimulates non-invasively parts of the brain. Preliminary data suggest that rTMS may help reducing cocaine craving and consumption. Researchers want to learn how the brain and the drug-seeking behavior may change with this treatment. Objectives: To test if rTMS can reduce cocaine craving and use, and also affect several mood, behavioral and cognitive alterations associated with prolonged cocaine use. Eligibility: Healthy, right-handed adults ages 18-65 who do have cocaine use disorder (moderate to severe). Design: This is a randomized, double-blind, sham-controlled study. The study includes three phases: 1) a rTMS continued treatment phase; a rTMS follow-up; and a no rTMS follow-up. Prior to participating, participants will be screened with: - Questionnaires - Medical history - Physical exam - Urine tests - MRI (structural) After being enrolled, baseline behavioral and imaging data will be collected. In particular, participants will undergo: - Questionnaires - Functional MRI During the continued rTMS phase, participants with cocaine use disorder will be randomized to receive real or fake rTMS. Repetitive TMS will be delivered during 10 outpatient treatment days, over 2 weeks (5 days/week). Following this phase, subjects will have 12 follow-up visits (once/weekly), during which they will receive rTMS, and behavioral and imaging assessments will be performed. At the end of the rTMS follow up period, participants will further receive 3 follow up visits (once a month), during which rTMS will not be performed, but behavioral data will be collected. Treatment includes: - rTMS: A coil is placed on the head. A brief electrical current passes through the coil. At each visit, participants will receive two rTMS sessions, with a 1hr interval between sessions. At the beginning of each rTMS session, they view cocaine-related images for few minutes. - MRIs at baseline and at follow-up visit #12: Participants lie on a table that slides into a cylinder that takes pictures of the brain. They respond to images while in the scanner. - Repeat of screening tests and questionnaires - Urine toxicological screen
