NCT01690130

Brief Summary

The proposed study will measure the change of cortical excitability during nicotine craving and examine the effects of Repetitive Transcranial Magnetic Stimulation (rTMS) on nicotine craving and cue-reactivity among adult regular smokers.

Outcome Measures

Primary Outcomes (1)

  • the Change From Baseline in Cue Nicotine Craving Rating Score

    Seventy highly palatable scenic images, forty neutral control images) and forty cigarette smoking cue images were presented in four blocks. Immediately after viewing each block of cue images, participants completed a 10 question computerized visual analog scale (CVAS) designed to assess craving. Each question is followed by a CVAS (range 0 - 100) 0 means least amount of craving and 100 means the maximum amount of craving. After 15 minutes of real or sham rTMS, participants viewed the images again and rated their cravings. At each visit, participants were blind to the rTMS condition (real or sham) and the order was randomized.

    Before rMTS (baseline) and after rTMS experiment (on average 15 minutes)

Secondary Outcomes (1)

  • the Change From Baseline in Resting Motor Threshold

    20 minutes before (baseline) and 20 minutes after rTMS experiment

Study Arms (2)

Transcranial Magnetic Stimulation

EXPERIMENTAL

Transcranial magnetic stimulation (TMS) is a noninvasive (and relatively painless) brain stimulation technology that can focally stimulate the brain of an awake individual.The brain stimulation techniques could theoretically improve the efficacy of smoking cessation. Treatment was standardized at 100% magnetic field intensity relative to the participant's resting MT, at 10 pulses per second (10 Hz) for 5 seconds, with an intertrain interval of 10 seconds. Treatment session lasted for 15 minutes with 3000 pulses.

Sham Transcranial Magnetic Stimulation

SHAM COMPARATOR

Sham-TMS procedures: After rMT determination and DLPFC cortex localization, participants were fitted with two electrodes on the scalp just below the hairline. Electrodes were connected to an Epix VT® Transcutaneous Electrical Nerve Stimulation Device (Empi; St. Paul, MN, USA)

Device: Transcranial Magnetic Stimulation (Neuronetics)Device: Sham Transcranial Magnetic Stimulation

Interventions

Transcranial magnetic stimulation is a noninvasive brain stimulation that can focally stimulate the brain of an awake individual. A TMS pulse focally stimulates the cortex by depolarizing superficial neurons which induces electrical currents in the brain.

Also known as: Neuronetics® Model 3600
Sham Transcranial Magnetic StimulationTranscranial Magnetic Stimulation

The electrical current of the sham system is titrated to a level matching participants' ratings of active TMS.The sham-TMS scalp discomfort will be matched to that of active TMS.
