Clinical trials

Background: Alzheimer's disease is a major health problem in our society. To date, pharmacological treatments to reduce Alzheimer's disease symptoms have obtained poor results and there is a growing interest in finding non-pharmacological treatments for this impactful disease. Transcranial Magnetic Stimulation is a non-invasive tool which can induce changes in brain activity and long term modifications of impaired neural networks, and therefore holds promise as a clinical intervention. Our overall goal is to study the benefit of targeting Transcranial Magnetic Stimulation based on the individual's unique functional connectivity (personalized targeting) instead of current non-individualized approaches. Specifically, the intermittent Theta Burst protocol will be used and changes in cognitive, functional, and emotional deficits in these patients will be evaluated. Functional brain connectivity changes induced by the TMS treatment will be also assessed. Methods: A double blind randomized controlled trial will be conducted to assess the effects of TMS treatment immediately, one month, three months and six months after the end of the treatment in comparison to the baseline measurements. Forty-five patients with a diagnosis of Alzheimer's disease, will be randomly allocated (1:1:1) into experimental (active Transcranial Magnetic Stimulation), sham control group, or conventional intervention control group. Neuropsychological, functional, and emotional assessment will be conducted, as well as functional connectivity measures, in order to assess the effectiveness of the treatment. Discussion: The investigators expect to demonstrate that personalized Transcranial Magnetic Stimulation intervention has measurable positive impact in cognitive and emotional functioning, functionality, and brain connectivity, thus representing a potential treatment for Alzheimer's disease.

The goal of this clinical trial is to evaluate the effectiveness of REVISE (REalidad Virtual Inmersiva y SExualidad), an immersive virtual reality (IVR) intervention designed to promote empathy and reduce sexual harassment behaviors in heterosexual cisgender men. The main questions that this study aims to answer are as follows. Does experiencing gender swapping in IVR increase empathy towards survivors of sexual harassment? Does the intervention modify attitudes toward gender roles and sexual harassment? Researchers will compare the three experimental groups to evaluate the effects of IVR: 1. Identity Exchange Group with Exposure to Sexual Harassment: Participants embodied their partner's identity in a VR harassment scenario. 2. Identity Exchange Group without Harassment Exposure: Participants embodied their partner's identity in a neutral VR scenario. 3. Third-person Observer Group: Participants observe a harassment scenario in VR from their own perspective. Participants will: 1. Attend one virtual reality session in a laboratory setting. 2. Undergo pre- and post-intervention assessments and a three-month follow-up. 3. Complete self-report questionnaires and physiological measures (eye tracking and pupillometry). 4. Participate in semi-structured interviews about their experiences. This study aims to explore how immersive VR embodiment can be used as a tool for gender violence prevention by fostering perspective-taking and behavioral change.
