L’aumento dell’aspettativa di vita ha comportato un significativo incremento delle patologie neurodegenerative. Il progressivo invecchiamento della popolazione rende oggi cruciale la distinzione tempestiva tra invecchiamento fisiologico e patologico. In questo scenario, l'identificazione precoce del Mild Cognitive Impairment (MCI), inteso come fase prodromica di transizione e "finestra terapeutica" ottimale, costituisce una priorità non solo clinica, ma anche di salute pubblica ed economica. Il presente elaborato si propone di analizzare l'evoluzione e l'efficacia degli strumenti di screening neuropsicologico, evidenziando come i test tradizionali di prima generazione, quali il Mini-Mental State Examination (MMSE), presentino severi limiti intrinseci. Tra questi emergono una forte vulnerabilità ai bias sociodemografici legati alla scolarità, l'incapacità di mappare adeguatamente le funzioni fronto-esecutive e un marcato effetto tetto, che porta a una pericolosa sottostima del declino nelle fasi iniziali. Attraverso una revisione della letteratura e dei recenti dati normativi italiani, l'elaborato confronta la capacità discriminativa del Montreal Cognitive Assessment (MoCA) rispetto al MMSE, dimostrando come una struttura multidimensionale e maggiormente sfidante garantisca una valutazione equa e precisa. Particolare attenzione viene dedicata alla versione 8.1 del test e all'introduzione del Memory Index Score (MoCA-MIS), un indice clinico innovativo concepito per quantificare accuratamente i deficit di memoria episodica differita e individuare precocemente i pazienti a maggior rischio di conversione verso la demenza. In conclusione, lo studio evidenzia come l'adozione di strumenti ad elevata sensibilità sia un prerequisito metodologico fondamentale per il neuropsicologo: non solo per ridurre i falsi negativi e garantire diagnosi tempestive, ma soprattutto per supportare interventi preventivi mirati e tutelare l'autonomia e la validità ecologica del paziente.

Abstract
The increase in life expectancy has led to a significant rise in neurodegenerative diseases. The progressive aging of the population makes the timely distinction between physiological and pathological aging crucial today. In this scenario, the early identification of Mild Cognitive Impairment (MCI)—understood as a prodromal transitional phase and an optimal "therapeutic window"—constitutes not only a clinical priority but also a public health and economic one. The present study aims to analyze the evolution and efficacy of neuropsychological screening tools, highlighting how traditional first-generation tests, such as the Mini-Mental State Examination (MMSE), present severe intrinsic limitations. Prominent among these are a strong vulnerability to education-related sociodemographic biases, the inability to adequately assess fronto-executive functions, and a marked ceiling effect, which leads to a dangerous underestimation of cognitive decline in its early stages. Through a literature review and the analysis of recent Italian normative data, this paper compares the discriminative capacity of the Montreal Cognitive Assessment (MoCA) with that of the MMSE, demonstrating how a multidimensional and more demanding structure ensures a fair and accurate assessment. Particular attention is devoted to version 8.1 of the test and the introduction of the Memory Index Score (MoCA-MIS), an innovative clinical index designed to accurately quantify delayed episodic memory deficits and early identify patients at higher risk of conversion to dementia. In conclusion, the study highlights how the adoption of highly sensitive tools is a fundamental methodological prerequisite for neuropsychologists: not only to reduce false negatives and ensure timely diagnoses but, above all, to support targeted preventive interventions and protect the patient's autonomy and ecological validity.| File | Dimensione | Formato | |
