Plain English summary of protocol

Background and study aims
Nicotine use disorder, also known as tobacco addiction, is a serious condition that can make it difficult to stop using tobacco products. This study investigates electrical changes in the brain under the influence of direct current brain stimulation (tDCS) to better understand the disorder's basis and provide alternative treatments. tDCS is known to have some benefits according to previous studies in rehabilitation medicine, post-stroke movement disorders, nerve studies and other substance disorders.

Who can participate?
People aged 18-55 years with nicotine use disorder

What does the study involve?
Participants will receive tDCS intervention lasting 20 minutes per session. These sessions will occur 5 days a week, spanning 2 weeks. Participants undergo an electroencephalogram (EEG) recording at 6 weeks.

What are the possible benefits and risks of participating?
There are no direct benefits to participants. However, participation might help to improve our understanding of nicotine use disorder and provide better treatment in the future. The device used is simple and safe. No invasive procedures are involved as the device is applied across the head surface without creating any wounds. There might be an unpleasant tingling sensation, headache, itchiness, or burning sensation during the procedure due to the placement of electrodes.

Where is the study run from?
Hospital Permai (Malaysia)

When is the study starting and how long is it expected to run for?
January 2024 to December 2024

Who is funding the study?
Monash University (Malaysia)

Study information

Study designThis exploratory research (involve intervention) is focused on examining the impact of transcranial Direct Current Stimulation (tDCS) on subjects diagnosed with nicotine use disorder. The study primarily utilizes Electroencephalography (EEG) to monitor and analyze changes in cortical activities resulting from the tDCS intervention. The objective is to understand how tDCS influences brain function in individuals affected by nicotine dependence.

Scientific titleThe effects of transcranial direct current stimulation on EEG changes in nicotine use disorder patients: an exploratory study
Study acronymtDCSN
Study objectives1. There are EEG changes (alpha, beta delta and theta wave at different regions, including the prefrontal lateral lobe) before and after transcranial direct current stimulation (tDCS) in nicotine use disorder patients.
2. There is efficacy of tDCS in the treatment of nicotine withdrawal.

Health condition(s) or problem(s) studiedNicotine use disorder
InterventionTranscranial Direct Current Stimulation (tDCS). Participants will receive tDCS intervention lasting 20 minutes per session. These sessions will occur 5 days a week, spanning 2 weeks. The tDCS will be delivered following standardized protocols to ensure safety and uniformity across treatments. There is no control group, hence, no randomisation is required.
