tDCS to Reduce Craving in Cocaine Addiction
Transcranial Direct Current Stimulation (tDCS) to Reduce Craving in Cocaine Addiction
Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation in which low level electrical currents are applied to the scalp in order to alter brain function. In the present study, tDCS will be administered with the goal of assessing the tolerability and feasibility of this approach to 1) reduce an individual's level of drug craving and 2) provide evidence to support the use of this device by the patient for future unsupervised stimulation in a non-clinical setting.
Research Questions:
- Can tDCS be used successfully to train cocaine addicted individuals for self-administration purposes?
- Can active tDCS be used to decrease drug craving in individuals with cocaine use disorders?
- Does active tDCS outperform sham tDCS in reducing drug craving?

Detailed Description
The ultimate goal of this project is to develop a portable neuromodulatory intervention to reduce craving in cocaine addiction. This proposed project is in response to NIH/NIDA's solicitation titled "Development of Portable Neuromodulatory Device for the Treatment of Substance Use Disorders (SUDs)." The present study aims to evaluate the tolerability and feasibility of repeated administration of tDCS to reduce drug craving in individuals with cocaine addiction, with the aim of using these data to support a phase II study and, ultimately, support of approval of usage of this device without clinical supervision.
The specific objectives are:
- Establish the feasibility and safety of using tDCS to reduce self-reported cravings in individuals addicted to cocaine.
- Train cocaine addicted individuals to self-administer tDCS (under supervision) to test the feasibility of future home self-administration in this population.
Substance use disorders present a treatment challenge for clinicians, as well as a socioeconomic burden on individuals and society at large. Cocaine use disorder occurs when someone experiences clinically significant impairment caused by the recurrent use of cocaine, including health problems, physical withdrawal with discontinuation of use, persistent/escalating use, and failure to meet major personal, occupational, or educational responsibilities. At present, no FDA approved medicines are available to treat cocaine dependence, and behavioral therapy may be used to treat this addiction, though with limited efficacy. Drug craving (strong obsessions about and/or irresistible urges or compulsions to consume a drug) is a central driving force for perpetuation of substance use and subsequent addiction, as well as relapse after abstinence. Currently, no treatments exist that are targeted at reducing drug craving, which is intrusive and distressing to patients. The prefrontal cortex (PFC) plays an important role inhibiting these intrusive cravings. However, decades of data have shown that PFC activity is impaired in addictions. In this study, our goal is to increase PFC activity with non-invasive neuromodulation. Given the role of the PFC in the processing and regulation of craving behavior, this brain region is a key target for brain stimulation.
This study will recruit individuals with a diagnosis of cocaine use disorder (per DSM-5 criteria) who are receiving treatment for their substance use disorder at Samaritan Daytop Village (SDV) and other similar treatment facilities (e.g., Phoenix House, Mount Sinai's network of hospitals and clinics). Patients will be randomly assigned to receive either active or sham (placebo) tDCS. Participants will receive 20 minutes of stimulation per tDCS day, three days per week for five weeks.
Interviews and neuropsychological testing will be conducted, and self-reported drug craving and addiction severity questionnaires will be used. Follow up cognitive and behavioral assessments will be conducted over a period of 12 months post tDCS stimulation. In addition, participants will be asked to perform EEG, cognitive tasks, and collection of a blood sample to assess genetic/epigenetic patterns.

An abbreviated instrument of cross-culturally valid assessment of quality of life of the World Health Organization (WHOQOL-BREF) with 26 questions (WHOQOL Group, 1998; Skevington et al., 2004) yields 4 domains (physical health, psychological, social relationships, and environment) and 2 individually scored items regarding overall perception of quality of life (Q1) and health (Q2).
The 4 domain scores are scaled in a way that higher scores stand for higher quality of life.
