Functional neuroimaging studies have begun to document a functional reorganization in the PD brain across a wide number of networks. In particular, the cerebellar-thalamocortical, as well as the fronto-striatal circuit, have been shown to undergo functional reorganization. In this narrative review, citing preclinical as well as clinical neuroimaging studies, our objective is to highlight trends and discuss the relevance of cerebral adaptive changes. It remains clear that not all changes contribute to the normalization of functions. Parsing differences between functional \"compensation,\" \"silencing,\" or \"maladaptation\" in neural circuits is important. A necessary next step in neurorehabilitation is the question of whether compensatory cerebral changes can be enhanced.

However, a consensus regarding prosocial paradigms in rodents remains scattered.

The conceptual framework and decision tree are concise and straightforward, providing a robust foundation for the ongoing utilization of current models and the creation of novel paradigms.

This narrative review examines the effects of the Mediterranean, plant-based, ketogenic, Wahls, Swank, intermittent fasting, and gluten-free diets, alongside key nutrients such as omega-3 fatty acids, vitamin D, polyphenols, and antioxidants. Among these, Mediterranean and plant-based diets have shown the most consistent benefits, including reductions in fatigue, improved quality of life, and modulation of inflammatory markers. The Wahls and Swank diets show promise but are primarily supported by studies from their respective research groups, raising concerns about long-term adherence and nutritional adequacy. The ketogenic diet and intermittent fasting have yielded mixed findings, with some studies suggesting benefits for fatigue and neuroprotection, while others highlight potential metabolic risks. The gluten-free diet and omega-3 supplementation lack robust evidence, with inconsistent findings across studies. Additionally, ultra-processed foods and diets high in saturated fats have been associated with increased inflammation and greater MS severity. Despite promising findings, limitations such as small sample sizes, short follow-up durations, and study design inconsistencies prevent definitive conclusions.
