Brief Summary

To demonstrate whether four sessions of TBS improves attentional bias and craving in PLWHA smokers compared to four sessions of sham stimulation. We hypothesize 4 sessions of TBS to the left DLPFC will significantly improve attentional bias and craving for smoking cues compared to neutral cues in a population of subjects who are smokers with HIV/AIDS compared to sham stimulation.

Outcome Measures

Primary Outcomes (4)

  • Gaze Fixation on Smoking Cues

    Measured using an eye tracker which quantifies this in milliseconds, higher score means worse outcome

    On Day 1 of the study

  • Gaze Fixation on Smoking Cues

    Measured using an eye tracker which quantifies this in milliseconds, higher score means worse outcome

    On Day 1 of the study after intervention

  • Craving for Cigarettes

    Measured using tobacco craving questionnaire (TCQ), this questionnaire has 12 items. Max score is 84, min score is 0. Higher score means that craving is higher.

    On day one of the study.

  • Craving for Cigarettes

    Measured using tobacco craving questionnaire (TCQ), this questionnaire has 12 items. Max score is 84, min score is 0. Higher score means that craving is higher.

    Immediately after intervention (sessions of TBS or sham TMS) on day 1

Secondary Outcomes (1)

  • Number of Participants Showing Functional Connectivity Changes

    on Day 1 of study

Study Arms (2)

TBS (Theta burst stimulation)

ACTIVE COMPARATOR

Four sessions of TBS in one day

Device: TBS

Sham TMS

PLACEBO COMPARATOR

Four sessions of sham TMS

Device: Sham TMS

Interventions

TBSDEVICE

Four sessions of TBS at 120 % resting motor threshold, delivered using MagVenture B65 A/P coil, each lasting 10 minutes and separated by 50 minutes intervals. Targeting will be done using neuronavigation and processed resting state brain scan.
