Study Description

Brief Summary:

Obesity is a metabolic disease that has reached epidemic proportions. Insofar no long-term effective drug treatment was developed for obesity. Lyfe style modulation and bariatric surgery are the only interventions with a limited rate of success. Obesity is due to several factors, mainly linked to a neurophysiological mechanism of "food addiction". The use of repetitive deep Transcranial Magnetic Stimulation (dTMS) was proposed to reduce appetite and food craving in obese subjects, leading eventually to a weight reduction. dTMS was already tested successfully in other forms of addiction (smoking, alcohol, cocaine) and the usefulness of dTMS in the treatment of food addiction, and therefore in obesity, was hypothesized. End-points of this research will be: 1) effect on food craving; 2) acute and chronic effects on blood level of hormones acting on the appetite regulation; 3) chronic effects on body weight. The demonstration that a safe, non-invasive and repeatable methodology can treat obesity reducing food craving and modulating appetite/satiety hormones secretion will constitute a cornerstone in translational medicine of metabolic diseases.

Arms and Interventions

Arm	Intervention/treatment
Experimental: High frequency repetitive dTMS + Cue; 10 obese individuals fulfilling all inclusion/exclusion criteria for the study will be randomized to active high frequency repetitive dTMS treatment with cue. Stimulation will be performed 3 times per week, for 5 weeks (15 treatments). In this group, stimulation will be performed with the following features: Intensity of stimulation: 120% of the resting Motor Threshold (rMT), Frequency: 18 Hz, Duration of the train: 2 sec, Inter-train interval: 20 sec, Trains number: 80, Total pulses: 2880, Total treatment duration: 29.3 min, Cue (sight of food preferred by patient): present.	Device: High frequency repetitive dTMS; Focal rTMS will be performed using a Magstim Rapid2 magnetic stimulator (The Magstim Co. Ltd., U.K.) equipped with an H-shaped coil. The used H-coil version is the H-addiction specifically designed to stimulate the insula and the Pre-Frontal Cortex (PFC). This novel H-coil allows direct stimulation of deeper brain regions, like insula (3 cm vs 1.5 cm from the skull). Before each stimulation the resting Motor Threshold (rMT) should be determined. The rMT will be determined over the left primary motor cortex, afterwards the coil will be moved forward 6 cm anterior the motor spot and aligned symmetrically over the PFC and insula. Repetitive dTMS induces long-lasting changes in neural excitability and dopamine release, specifically high-frequency rTMS (18 Hz) enhances cortical excitability.
Experimental: High frequency repetitive dTMS - No Cue; 10 obese individuals fulfilling all inclusion/exclusion criteria for the study will be randomized to active high frequency repetitive dTMS treatment without cue. Stimulation will be performed 3 times per week, for 5 weeks (15 treatments). In this group, stimulation will be performed with the following features: Intensity of stimulation: 120% of the resting Motor Threshold (rMT), Frequency: 18 Hz, Duration of the train: 2 sec, Inter-train interval: 20 sec, Trains number: 80, Total pulses: 2880, Total treatment duration: 29.3 min, Cue (sight of food preferred by patient): absent.

Experimental: Low frequency repetitive dTMS+ Cue; 10 obese individuals fulfilling all inclusion/exclusion criteria for the study will be randomized to active low frequency repetitive dTMS treatment with cue. Stimulation will be performed 3 times per week, for 5 weeks (15 treatments). In this group, stimulation will be performed with the following features: Intensity of stimulation: 120% of the resting Motor Threshold (rMT) Frequency: 1 Hz Duration of the train: 10 min Inter-train interval: 1 min Trains number: 4 Total pulses: 2400 Total treatment duration: 43 min Cue (sight of food preferred by patient): present	Device: Low frequency repetitive dTMS; Focal rTMS will be performed using a Magstim Rapid2 magnetic stimulator (The Magstim Co.

Sham Comparator: Sham; 10 obese individuals fulfilling all inclusion/exclusion criteria for the study will be randomized to sham stimulation. Stimulation will be performed 3 times per week, for 5 weeks (15 treatments). In this group, stimulation will be performed with the following features: Intensity of stimulation: 120% of the resting Motor Threshold (rMT), Frequency: 18 Hz (50% of patients) and 1 Hz (50% of patients), Duration of the train: 2 sec or 10 min, Inter-train interval: 20 sec or 1 min, Trains number: 80 or 4, Total pulses: 2880 or 2400, Total treatment duration: 29.3 or 43 min, Cue (sight of food preferred by patient): present.	Device: Sham; Sham stimulation will be performed by an H-sham-coil. The H-sham-coil is designed to mimic the auditory artifacts and the scalp sensation evoked by the real coil, without stimulating the brain itself. As in the other groups, in each patient the rMT will be determined before each repetitive dTMS session. The sham stimulation will be performed either at high frequency (50% of subjects) or at low-frequency (50% of subjects), according to the previously described methodologies. All obese people in this group will be submitted at the sight of food preferred (cue).
