Summary

The presence of damage to the central and/or peripheral nervous system resulting from various pathologies, such as Multiple Sclerosis (MS), Amyotrophic Lateral Sclerosis (ALS), Parkinson's disease (PD), Alzheimer's disease (AD), dementia, traumatic brain injury (TBI), stroke, or other neurological syndromes, is commonly a cause of both physical and mental disability. This leads to symptoms in the patient, including: pain, migraines, headaches, neuropathic pain, trigeminal neuralgia, depression, anxiety, apathy, fatigue, cognitive decline, aphasia, functional motor disorders (FMD), neuromuscular tone alterations, and hyposthenia, in addition to involvement of various cognitive functions, such as decision-making, problem-solving, learning, memory, executive functions, social cognition, and emotional cognition. The presence of these neurological symptoms is often evident in a first clinical examination and is one of the main reasons for further healthcare consultations. These difficulties have a profound impact on the quality of life, affecting work, social, and family functioning. In recent years, several non-invasive brain stimulation (NIBS) techniques have emerged, aimed at eliciting brain neural networks, such as transcranial static magnetic field stimulation (tSMS) and transcranial direct current stimulation (tDCS). tSMS is an NIBS technique that involves the application of a neodymium magnet on the scalp. Since the first study proposing this method, several others have confirmed that tSMS can reduce corticospinal excitability. tDCS involves the application of weak electrical currents capable of generating an electric field that can modulate neural activity in an excitatory or inhibitory manner. NIBS techniques can be used experimentally to modulate cortical activity. The primary aim of this proposal is to address the impact of neurological symptoms through the combination of tSMS with tDCS and rehabilitation techniques. Specifically, it aims to understand whether the combination of these neuromodulatory therapeutic NIBS methods can enhance symptom improvement in patients with neurological conditions. To assess the impact of this intervention, a series of tests and questionnaires, described in detail below, will be used to evaluate the severity of the reported symptoms and secondary outcomes. Moreover, the contribution of specific brain areas to the symptom will be evaluated through the direct modulation of brain activity. This modulation will be achieved using an additional NIBS technique, such as Transcranial Magnetic Stimulation (TMS). TMS, in particular, is a non-invasive method for stimulating neurons in the brain's superficial areas, which has been frequently used in neurology as a diagnostic and research tool since its introduction. TMS uses magnetic fields to induce electrical currents capable of facilitating or inhibiting cortical activity.
