Anorexia Nervosa is a psychiatric disorder characterized by high rates of chronicity, significant societal costs, and one of the highest mortality rates among psychiatric illnesses. Despite therapeutic advances, treatment outcomes remain poor, with high relapse rates and full recovery achieved in only 50% of cases.
Recent cognitive, behavioral, and neuroimaging studies suggest that Anorexia Nervosa may involve dysfunction in a posterior parietal network responsible for multisensory integration. This network plays a pivotal role in bodily self-representation and the modulation of environment-body interactions, and may therefore be directly implicated in two core symptoms of the disorder: distorted body image representation and dietary restriction. Given these insights, Transcranial Magnetic Stimulation (TMS) - an established neuromodulation technique with proven efficacy in various psychiatric disorders - emerges as a promising investigational intervention. The aim of this study is to evaluate the feasibility and therapeutic efficacy of a protocol of intermittent Theta Burst Stimulation (iTBS) targeting the right posterior parietal lobe in patients with Anorexia Nervosa. The active iTBS protocol will be compared to a sham (placebo) stimulation as a control condition.
