Brief Summary
The purpose of this study is to examine the effects of noninvasive neuromodulation with transcranial direct current stimulation (tDCS) aimed at enhancing the excitability of the left prefrontal cortex in middle-aged women with excess body weight. This is a randomized, parallel, double-blind study with a duration of 4 weeks. Outcome measures will include changes in performance in a computerized task assessing executive functions, subjective measures of food craving and appetite and changes in body weight.

Active tDCS Group
ACTIVE COMPARATORSubjects will receive a total of eight tDCS sessions: 1st week five daily sessions (Monday to Friday), followed by 2nd week three sessions only (Monday, Wednesday, Friday). tDCS sessions will consist of 20 minutes stimulation at 2mA. Target: left dorsolateral prefrontal cortex (DLPFC). Montage: 5x5 sponge electrodes placed over EEG 10:20 system location F3 (anode) and right supraorbital area (cathode).
Sham tDCS Group
SHAM COMPARATORSubjects will receive a total of eight tDCS sessions: 1st week five daily sessions (Monday to Friday), followed by 2nd week three sessions only (Monday, Wednesday, Friday). tDCS sessions will be sham stimulation (30-second ramp up and down). Target: left dorsolateral prefrontal cortex (DLPFC). Montage: 5x5 sponge electrodes placed over EEG 10:20 system location F3 (anode) and right supraorbital area (cathode).
Interventions
Transcranial Direct Current Stimulation (tDCS) is a noninvasive form of neuromodulation that uses constant, low-intensity direct current delivered via electrodes that are placed on the head.
Eligibility Criteria
You may qualify if:
