Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Transcranial Direct Current Stimulation

These subjects will receive real transcranial direct current stimulation.

Group Type EXPERIMENTAL

Transcranial Direct Current Stimulation

Intervention Type DEVICE

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.

Sham tDCS

These subjects will receive sham transcranial direct current stimulation (placebo)

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type OTHER

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.
