Effects of Transcranial Direct Current Stimulation on Cigarette Addiction

May 28, 2016 updated by: Joaquim Brasil-Neto, University of Brasilia

Effects of Transcranial Direct Current Stimulation of the Prefrontal Cortex on Cigarette Smoking

Tobacco addiction is treatable with behavioral and pharmacological means, but results are often less than optimal. Transcranial direct current stimulation is a new non-invasive technique that applies weak electrical currents through the skull and has been shown to alter the excitability of certain brain areas. It is currently being tried in disorders where there is abnormal brain excitability, such as epilepsy and depression. A few studies have also been able to diminish drug craving, suggesting that brain excitability might also be altered in drug addiction.

This study aims at non-invasively changing the excitability of certain brain areas-a procedure called neuromodulation- in order to help smokers quit smoking more easily.

  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Transcranial Direct Current Stimulation
These subjects will receive real transcranial direct current stimulation.
Transcranial Direct Current Stimulation (tDCS) is a procedure that uses a small battery-driven unit to deliver weak electrical currents (1-2 mA) through the intact scalp. The procedure is painless and is thought to modulate the excitability of the underlying cerebral tissue for hours or days after sessions.
Placebo Comparator: Sham tDCS
These subjects will receive sham transcranial direct current stimulation (placebo)

Transcranial Direct Current Stimulation (tDCS) is a procedure that uses a small battery-driven unit to deliver weak electrical currents (1-2 mA) through the intact scalp. The procedure is painless and is thought to modulate the excitability of the underlying cerebral tissue for hours or days after sessions.

In the placebo group the current will be off.
