"In addiction, brain systems can get out of balance. One system, tied to reward and craving, becomes overactive. Another, responsible for control and decision-making, becomes weaker."
"Treatment with rTMS has already shown promise for the treatment of depression, chronic pain, obsessive compulsive disorder, and more. Now, as outlined in a new study in the Journal of Psychiatric Research, researchers are investigating whether the technique could help patients quit smoking as well."
"Li's team ran experiments on 45 smokers trying to quit, each of whom received 15 treatment sessions, and they said the results were undeniable. Participants who received high-frequency stimulation to the dorsolateral prefrontal cortex, a region of the brain associated with decision-making and self-control, reported fewer cravings and reduced their tobacco use by an average of about 11 cigarettes per day."
"In other participants, Li's team targeted the medial orbitofrontal cortex, responsible for rewards and cravings, but that group only reduced i"
Nicotine addiction is difficult to overcome, with most adult smokers wanting to quit but few succeeding. Repetitive transcranial magnetic stimulation (rTMS) delivers targeted electromagnetic pulses to modulate neural activity without invasive procedures. rTMS has shown promise for depression, chronic pain, and obsessive compulsive disorder. A study investigated whether rTMS could help smokers quit by addressing brain system imbalance caused by addiction. In experiments with 45 smokers undergoing 15 treatment sessions, high-frequency stimulation to the dorsolateral prefrontal cortex was associated with fewer cravings and an average reduction of about 11 cigarettes per day. Targeting the medial orbitofrontal cortex produced less reduction in tobacco use.
