La visione tradizionale del cervelletto lo ha a lungo considerato una struttura deputata principalmente nella regolazione motoria e nel controllo dei movimenti coordinati. Negli ultimi decenni, tuttavia, numerose evidenze sperimentali e cliniche hanno ampliato questa prospettiva, mostrando come il cervelletto, in stretta connessione con sistemi corticali e sottocorticali, svolga anche un ruolo rilevante nella modulazione di processi non motori, tra cui funzioni cognitive, emotive e comportamentali. L’osservazione di deficit cognitivi ed emotivi conseguenti a lesioni cerebellari ha sollevato l’ipotesi di un coinvolgimento del cervelletto anche in condizioni patologiche a esordio insidioso, come le malattie neurodegenerative. Per molti anni, tuttavia, il cervelletto è stato trascurato negli studi sull’Alzheimer, ritenuto interessato solo nelle fasi avanzate della malattia. In questo contesto, assume una particolare rilevanza il Subjective Cognitive Impairment (SCI), considerato una condizione a elevato rischio di progressione verso Mild Cognitive Impairment (MCI) e demenza conclamata. Tuttavia, il coinvolgimento cerebellare in questa fase precoce resta ancora poco esplorato. L’obiettivo del presente studio è indagare la possibile compromissione morfo-funzionale del cervelletto negli SCI, attraverso l’analisi delle differenze e delle correlazioni tra variabili neuropsicologiche, bioumorali e morfologiche, confrontando un campione di individui con SCI e un gruppo di controlli sani.

Abstract
The traditional view of the cerebellum has long considered it a structure primarily responsible for motor regulation and the control of coordinated movements. In recent decades, however, numerous experimental and clinical findings have broadened this perspective, demonstrating that the cerebellum, closely connected to cortical and subcortical systems, also plays a significant role in modulating non-motor processes, including cognitive, emotional, and behavioral functions. The observation of cognitive and emotional deficits following cerebellar lesions has raised the hypothesis of cerebellar involvement even in pathological conditions with insidious onset, such as neurodegenerative diseases. For many years, however, the cerebellum was overlooked in studies of Alzheimer's disease, believed to be affected only in the advanced stages of the disease. In this context, Subjective Cognitive Impairment (SCI) takes on particular relevance, considered a condition with a high risk of progression to Mild Cognitive Impairment (MCI) and full-blown dementia. However, cerebellar involvement at this early stage remains poorly explored. The aim of this study is to investigate the potential morpho-functional impairment of the cerebellum in SCI by analyzing the differences and correlations between neuropsychological, biohumoral, and morphological variables, comparing a sample of individuals with SCI with a group of healthy controls.| File | Dimensione | Formato | |
