Glucosinolates (GLs) are phytocompounds mainly found in the Cruciferae (Brassicacea) and Moringa oleifera plants. The hydrolysis of GLs by myrosinase led to the production of isothiocyanate (ITCs). ITCs consumption was associated with different health promoting effects, including to neuroprotective, anti-oxidant and anti-inflammatory capacities. In particular, they showed neuroprotective effects in experimental models of neurodegenerative diseases, including multiple sclerosis (MS) and Parkinson's disease (PD). From different GLs, different ITCs are originated. In particular, from glucoraphanin (GRA) the ITC sulforaphane (SFN) is obtained. The PI of the project is one of the proprietor of a patent (EP2908850B1) for the application of (Rs)-GRA with myrosinase in a buffered solution for the treatment of neurodegenerative diseases. The aim of this project is to evaluate the effects of the administration of bioactivated GRA in different cohorts of adult patients, affected by MS and PD, but also a cohort of pediatric patients affected by neuromuscolar and degenerative diseases. The effects of bioactivated (Rs)-GRA administration will be evaluated with a combination of clinical evaluations and a multiomic (metabolomic, genomic) approach.

Cognitive and Neuropsychological Assessments: Montreal Cognitive Assessment (MoCA) and Mini-mental state examination
The MoCA is a one-page 30-point test administered in approximately 10 minutes to dectect cognitive impairment. Scores range between 0 and 30, a score of 26 or over is considered to be normal. The mini-mental state examination (MMSE) or Folstein test is a 30-point test to identify cognitive impairment. Any score of 24 or more (out of 30) indicates a normal cognition. Below this, scores can indicate severe (≤9 points), moderate (10-18 points) or mild (19-23 points) cognitive impairment. The raw score may also need to be corrected for educational attainment and age

Changes in growth parameters, anthropometric measurements and pubertal status.
Evaluation of physical development and nutritional status. The following parameters will be measured: body weight (kg), height (cm), Body Mass Index (BMI, calculated as weight in kilograms divided by height in meters squared), and their respective percentiles adjusted for age, sex, and specific pathology. These measurements aim to assess the impact of the administration of the study composition on growth and development in the pediatric population. Additionally, pubertal development will be assessed using the Tanner Stage (Sexual Maturity Rating), which evaluates the progression of secondary sexual characteristics (breast development in girls, genital development in boys, and pubic hair in both) on a scale from 1 (pre-pubertal) to 5 (adult). This combined assessment aims to monitor the global growth trajectory and hormonal-physical maturation during the treatment.
