Epilepsy is a clinical condition that affects about fifty million people worldwide, with an estimated occurrence of 16-51 new cases per 100,000 people each year. In 60% of these patients, the origin of seizures is due to a localized (focal) alteration of the brain. In about 25 percent of patients with focal epilepsy, drug treatment is ineffective, a condition defined by the International League Against Epilepsy (ILAE) as drug-resistant epilepsy ; this condition results in a drastic reduction in quality of life associated with psychosocial dysfunction and an increased risk of sudden death. A possible treatment alternative for drug-resistant patients is ablation of the epileptogenic zone through surgical methods that are effective and safe when patients are carefully selected. The percentage of patients with epilepsy who are completely cured after surgery is about 70% for temporal lobe epilepsies, and can be as high as 90% in the case of some brain malformations. Pre-surgical screening and therapeutic intervention (particularly surgery) have health care costs that are amortized over 2-6 years depending on the procedures required before surgery. In the last decade, moreover, the refinement of noninvasive/mini-invasive methods such as radiosurgery, Magnetic Resonance-guided Focused Ultrasound (MRgFUS) and laser interstitial thermal therapy (LiTT) have allowed us to hypothesize a possible specific treatment of drug-resistant patients with epileptogenic areas that are difficult to reach with traditional surgery and patients with complex comorbidities for whom the risks of standard resective surgery would outweigh the possible benefits. Finally, there is a subgroup of patients with drug-resistant epilepsy who cannot undergo ablative surgery. In these patients, seizures originate from multiple areas of the brain (multifocal epilepsy) or the epileptogenic area affects functionally eloquent areas. In these cases, alternative functional treatments are proposed, which aim to decrease the frequency and intensity of seizures and the need for medication, such as: i) application of a vagal stimulator, a pulse generator that is implanted in the chest and connected to the vagus nerve, ii) implantation of deep brain stimulation devices, iii) neuromodulation. Therefore, careful selection of patients during the diagnostic/pre-surgical process is crucial. The multimodal assessments under study, proposed in support of clinical practice, aim to improve such selection by analyzing the causative factors of seizures, the location of the epileptogenic zone, and the clinical-epileptological course of patients who are candidates for surgical or functional treatment of epilepsies.

Diagnosis of ALS/FTD disease spectrum is challenging because it largely relies on clinical symptoms. Identifying novel biomarkers is essential for a paradigm shift towards a more precise biological-based diagnosis. To achieve this aim, having access to proper specimens and analytical methods is crucial. Our team of experts in neurology, biology, chemistry, physics, and AI will explore ALS/FTD from novel perspectives using transcriptomics, proteomics, genomics and other innovative approaches to analyzing easily accessible tissues. The seed amplification assay (SAA) will be also exploited to detect pathological TDP-43. This project aims to create disease fingerprints useful for patient stratification and monitoring of disease progression, and to evaluate the therapeutic efficacy in clinical trials, thus overcoming the limits of clinical interpretation. Discovering new biomarkers and cellular pathways will improve the diagnosis and treatment of these devastating diseases.

Clinical diagnosis of Parkinson's disease (PD), multiple system atrophy (MSA) and dementia with Lewy bodies (DLB) is challenging, especially in the early stages. Each disease is associated with distinct conformers of misfolded alpha-synuclein (maS) which form typical protein aggregates in the brain and represent key disease biomarkers. Thus, detection and characterization of intracerebral maS aggregates allow a definite diagnosis. The recent development of ultrasensitive assays enabled the detection of maS and other potential new biomarkers in peripheral tissues, although with several limitations. Here, the investigators propose to combine the expertise of leading and young researchers in the field of neurology, structural and molecular biology, biophysics and machine learning to perform ultrasensitive and multi-omics analyses of olfactory mucosa (OM), blood and urine of PD, MSA and DLB patients for detecting and characterizing key peripheral biomarkers allowing accurate disease recognition.

This three-year observational study involves patients of all ages undergoing endovascular treatment for various cerebral or spinal vascular conditions. It aims to assess pre- and post-operative clinical conditions, report complications, and identify preoperative indicators of treatment outcomes. Patients will also receive psychological support and Neuropsychological assessment. Clinical, medical, and demographic data will be recorded in a database during hospitalization and follow-up visits.

The goal of this clinical trial is to obtain initial feedback on the implementation of the STRATIF-AI platform and digital twin in the secondary prevention phase in patients with stroke, Moyamoya disease and Cerebral amyloid angiopathy, including adults of both sexes. The main questions it aims to answer is: how is the patients' experience regarding the use of the STRATIF-AI platform? Researchers will compare Arm 1, who use the STRATIF-AI app in addition to standard secondary prevention, against Arm 2, who receive standard secondary prevention only, to collect feedback regarding the platform usability. Participants in the Arm 1 will: * Complete cognitive and psychological assessments at the time of the first visit and after six months * Follow the indications received from the clinician for standard secondary prevention * Use the STRATIF-AI app daily for health management * Optionally, purchase wearable devices that connect to the app. * Participate in interviews at the six-month mark to share their experiences with the app. Patients in the Arm 2 will: * Complete cognitive and psychological assessments at the time of the first visit and after six months * Follow the indications received from the clinician for standard secondary prevention

The evaluation of neurosurgical outcomes varies from center to center, and the predictive factors that determine these outcomes are not fully known or shared. This study aims to assess outcomes and their predictors using measures agreed upon by the participating centers. Standardizing the evaluation of outcomes and predictors improves the quality of research, allows for data comparison, and facilitates a "common language" in routine clinical practice. Most importantly, it influences therapeutic decisions in various neurosurgical conditions. Clinically, the identified predictors can also be used during preoperative assessments to provide more precise guidance to patients undergoing surgery.

The goal of this prospective open label study is to elucidate the pathophysiology of dystonia and to understand how deep brain stimulation (DBS) influences brain networks. The investigators will enroll patients with dystonia implanted with DBS of the Globus Pallidus internus (GPi) with sensing implantable neurostimulators, capable of measuring GPi local field potentials (LFPs). The main questions it aims to answer are: * does DBS influence pallidal LFPs in the long term? * how the basal-ganglia-thalamo-cortical circuit is modified after DBS? * do LFPs changes correlate with clinical improvement? Participants will undergo to serial clinical evaluations, magnetoencephalography (MEG) and functional Magnetic Resonance Imaging (fMRI) studies. Primarily, the data obtained from our study might help in clarifying basic pathological electrophysiological features of dystonia. These features might be secondarily used in future to provide a framework for an effective application of closed-loop DBS in Dystonia.

Cerebral amyloid angiopathy (CAA) is one of the major types of cerebral small vessel disease, and a leading cause of spontaneous intracerebral hemorrhage and cognitive decline in elderly patients. Although increasingly detected, a number of aspects including the pathophysiology, the clinical and neuroradiological phenotype and the disease course are still under investigation. The incomplete knowledge of the disease limits the implementation of evidence based guidelines on patient's clinical management and the development of treatments able to prevent or reduce disease progression. The SENECA (SEarchiNg biomarkErs of Cerebral Angiopathy) project is the first Italian multicentre cohort study aimed at better defining the disease natural history and identifying clinical and neuroradiological markers of disease progression. By a multidisciplinary approach and the collection of a large and well phenotyped series and biorepository of CAA patients, the study is ultimately expected to improve the diagnosis and the knowledge of CAA pathophysiological mechanisms.

The project aims to perform both conventional nerve-conduction studies and axonal-excitability assessments using the TRONDF protocol in patients with selected forms of Charcot-Marie-Tooth disease, with comparison to individuals affected by dysimmune, acquired neuropathies, specifically chronic inflammatory demyelinating polyneuropathy (CIDP) and anti-MAG-neuropathy. The study further includes the analysis of nerve fibers obtained from skin biopsy in patients with CMT, as well as ultrasound evaluation of nerves (from the wrist to the axilla) and of intrinsic hand muscles. Axonal-excitability techniques involve the delivery of two electrical stimuli to the nerve under investigation; both stimuli vary in intensity, whereas only the first, known as the conditioning stimulus, varies in duration. Changes in response amplitude are then measured as these stimulation parameters are systematically adjusted. Some preliminary studies have already suggested the effectiveness of this method in distinguishing CMT1A from certain forms of acquired demyelinating disease, including acute inflammatory demyelinating polyradiculoneuropathy (AIDP) and CIDP. Despite the promising results, only a limited number of studies have so far been conducted in humans and mice, and no comprehensive and systematic study has yet been carried out describing the changes in axonal excitability in the various CMT subtypes, either in humans or in mouse models.

Patients undergoing cranial neurosurgery face a high-risk postoperative period, particularly during emergence from anesthesia and early recovery in the post-anesthesia care unit (PACU). Standard monitoring provides limited insight into brain and autonomic recovery processes. Heart rate variability (HRV) and processed electroencephalography (pEEG) may offer complementary markers of autonomic and cortical function, with potential to improve early detection of complications and guide individualized care.

Recent research links gut microbiota alterations to Autism Spectrum Disorders (ASD), a neurobiological condition with multifactorial bases. In some ASD patients, altered gut flora and increased intestinal permeability are observed, influencing the central nervous system's development and function. Chronic gastrointestinal (GI) symptoms are commonly associated with ASD and correlate with its severity. This non-pharmacological interventional clinical study aims to investigate the role of gut microbiota on ASD and the effectiveness of postbiotic-based dietary supplements in children aged 3-8 years old. Gastrointestinal symptoms, behavioral profile and analysis of intestinal metagenomic and metabolomic profiles will be assessed before and after one-month treatment. The results of the study could enhance understanding of non-pharmacological therapeutic approaches in ASD and improve clinical management strategies and the behavioural functioning for children with ASD.

Cerebrovascular diseases (CVDs) are one leading cause of morbidity and mortality worldwide. Despite intensive investigations, more than 30% of strokes remain of undetermined origin. Rare Cerebrovascular Diseases (rCVDs), including heritable (i.e., CADASIL, COL4A1 syndrome, Fabry disease) and acquired conditions (i.e., Sneddon syndrome, Moyamoya arteriopathy) account for a proportion of these strokes. However, rCVDs are often misdiagnosed since clinicians are not able to recognize them. Although rare, the identification of these stroke causes is important to establish appropriate management measures, including genetic counselling, and, if available, therapy. The lack of data on phenotype and clinical course of rCVDs, given the paucity of published series, makes the diagnosis and the development of therapies challenging. Furthermore, the molecular characterization of rCVDs is still lacking, despite progresses achieved in common stroke by applying high throughput approaches as multi-omics. Since the diagnosis and care of rCVDs require adequate expertise and instrumental tools, clinical and research activities are usually reserved to few specialized centers, mostly located in the North of Italy, leading patients to expensive trips for consultations. Therefore, the creation of a clinical and research network aimed at improving the diagnostic pathways of rCVDs is highly needed to improve the number of patients with rCVDs to better define the clinical phenotype and to transfer the knowledge on rCVDs in other centers overall Italy filling the geographical gap affecting Southern Italy.

This is an interventional non pharmacological study in pediatric patientis affected by Autism Spectrum Disorder. It ams to create a collection of iPSCs and hiNSCs derived from deeply characterized ASD patients, to omics-characterize the cells, and to study the behavioral pattern of microglia-like cells in the onset of ASD.

This study focuses on rare brain tumors, which are heterogeneous entities with different morphological, biological, and clinical characteristics. Due to their rarity, many of these tumors fall under the RARECARE definition of rare tumors. The main objective of the study is to standardize care models and pathways for patients with rare brain tumors, using Artificial Intelligence (AI) and Machine Learning (ML) techniques to identify specific predictors of postoperative outcomes. The study includes both retrospective and prospective phases, with the collection of clinical, cognitive, and psychological data at various time points. Patients will undergo an early neuro-cognitive rehabilitation program using the RehaCom software, which will be conducted at home. The goal is to improve the quality of life and care for patients through a multidisciplinary and innovative approach.

Glioblastoma (GBM) is the most common and lethal primary brain tumor. Identifying blood biomarkers that reflect the tumor's status is a major unmet need for optimal clinical management. 5-ALA (5-Aminolevulinic Acid) administration leads to the accumulation of fluorescent Protoporphyrin IX (PpIX) in GBM cells, allowing identification during surgery. This project aims to leverage 5-ALA induced fluorescence to maximize the informational power of plasma liquid biopsy as a tool for diagnosis, post-treatment follow-up, and as a prognostic tool in patients with GBM.

Cervical dystonia is a condition that causes the neck muscles to tighten or spasm, leading to abnormal head positions and pain. The main questions it aims to answer are: * Do ultrasound-guided BoNT injections improve quality of life more than injections without ultrasound? * Are ultrasound-guided injections as safe as injections without ultrasound? Researchers will compare: * BoNT injections with ultrasound guidance * BoNT injections without ultrasound guidance (based only on body landmarks) Participants will: * Receive both types of injections during the study (one first, then the other) * Complete questionnaires about quality of life, movement, pain, and mood * Attend follow-up visits over about 8 months About 37 adults with cervical dystonia will take part. The study will take place at the Fondazione IRCCS Istituto Neurologico Carlo Besta in Milan, Italy.

This is an observational study in pediatric patientis carryng PTEN pathogenic variants aimed to define oncological risk in children and provide a deeper insight of the clinical course, establishing an updated follow-up protocol.

The aim of the study is to describe the socio-demographic, clinical, psychological, and psychiatric characteristics of patients with drug-resistant focal epilepsy eligible for epilepsy surgery and any changes in these parameters over time after surgery. Additionally, the study seeks to describe the levels of quality of life, dissociative experiences, prevalence of various psychiatric symptoms, irritability, depressive symptoms, anxiety symptoms, and stigma perception in patients with drug-resistant focal epilepsy eligible for epilepsy surgery and any changes over time after surgery.

To compare the performance of the Eleveld models for propofol and remifentanil on neurosurgery patients admitted to intensive care with their intraoperative performance.

This study aims to translate and validate the Gastrointestinal Dysfunction Scale for Parkinson's Disease (GIDS-PD) into Italian to enable the assessment of gastrointestinal symptoms in Italian-speaking patients with Parkinson's disease. The psychometric properties of the translated instrument will be evaluated through a multi-phase process involving translation/back-translation, pre-testing, and large-scale validation across multiple Italian centers

Meningiomas are the most common primary intracranial tumors. Current treatment relies on surgical resection and radiotherapy, but molecular predictors for recurrence are lacking. This study aims to investigate epigenetic features, specifically histone post-translational modifications (PTMs) and DNA methylation, to stratify patients. The study involves a retrospective cohort to define an epigenetic signature and a prospective cohort to validate it in tissues and liquid biopsies (plasma/EVs).

The overall objective is to define the neuropsychological profile of patients with migraine and evaluate its association with: psychological outcome measures (anxiety-depressive symptoms, pain catastrophizing, excessive worry, and coping strategies); the clinical profile of migraine; the prodromal, ictal, or interictal phase of the migraine attack; pharmacological therapy; and detoxification treatment in patients with migraine associated with medication overuse headache.

The FLUO.CER.TUM study is a prospective observational clinical trial conducted at the IRCCS Foundation Neurological Institute "Carlo Besta" in Milan, Italy. It investigates the intraoperative use of intravenous sodium fluorescein as a fluorescent tracer to assist in the surgical resection of suspected malignant tumors of the central nervous system (CNS). These tumors typically present as contrast-enhancing masses on pre-operative MRI or CT scans. Malignant brain tumors are notoriously difficult to fully resect due to challenges in distinguishing tumor margins from healthy tissue. Sodium fluorescein, a dye that accumulates in areas where the blood-brain barrier is disrupted, offers a promising solution by enhancing tumor visualization during surgery. When used with a dedicated surgical microscope equipped with a fluorescence filter, fluorescein can help surgeons identify and remove more tumor tissue, potentially improving patient outcomes. The study aims to evaluate the effectiveness and safety of fluorescein-guided surgery in a real-world clinical setting. Approximately 800 patients of any age and gender, with suspected aggressive CNS lesions, will be enrolled. Each patient will receive 5 mg/kg of sodium fluorescein intravenously at the induction of anesthesia. Surgery will be performed using fluorescence-guided techniques, and patients will undergo pre- and post-operative imaging to assess the extent of resection. Clinical and neurological evaluations will also be conducted to monitor outcomes and any adverse effects. The primary objective is to qualitatively assess the intraoperative fluorescence characteristics of CNS tumors. Secondary objectives include measuring the extent of tumor resection, evaluating post-operative neurological function, and documenting any side effects related to fluorescein administration. The study adheres to ethical standards, including informed consent and approval by an ethics committee, and will be conducted in accordance with Good Clinical Practice guidelines and the Declaration of Helsinki. Data will be anonymized and securely stored, with results potentially published following appropriate review and approval.
