Abstract: The rising rates of neurodegenerative disorders like Alzheimer’s and Parkinson’s necessitate the adoption of intelligent, personalized, scalable, and adaptable systems of healthcare to meet the growing demand. This paper examines the attempt to apply precision medicine with multi modal generative artificial intelligence (AI) for the proactive and ongoing assessment of neurodegenerative disorders. From a machine learning perspective, our work analyzes how basic clinical tools such as cognitive assessment tests including Mini-Mental State Examination (MMSE) can enhance performance of health predictive models of AI based systems when used alongside other demographic variables like age, gender and educational level. We conducted a statistical analysis on data that was divided into the following four categories: healthy subjects, subjects with mild neurocognitive impairment, moderate neurocognitive impairment, and severe neurocognitive impairment. Analysis of variance revealed a strong negative relationship between the mean MMSE scores and the severity of the condition with mean scores significantly decreasing across stages. Age was shown to strongly negatively influence (r = -0.72) MMSE scores, confirming that older age is a prominent risk factor. Higher levels of education were positively correlated with cognitive scores supporting the cognitive reserve hypothesis while gender did not statistically influence MMSE performance. The study confirms the possibilities associated with simpler computational techniques mean, standard deviation, Pearson correlation evaluation to generate clinically useful information. This chapter concludes by emphasizing the need for more holistic datasets, responsible model building, ethical algorithms, and the embedded computing stream of neural networks that encompass cognitive, behavioral, social, and biological data within generative AI paradigms.
