What this Trial Is About

In recent decades, advances in medicine have significantly improved both quality of life and life expectancy. However, these positive effects are also associated with a considerable increase in the prevalence of age-related diseases. Among these, Alzheimer's disease (AD), Parkinson's disease (PD), and type 2 diabetes (T2D) currently represent a major threat to human health. PD and AD are the most common neurodegenerative diseases in industrialized populations. In particular, AD accounts for 54% of all cases of dementia, with a prevalence of 4.4% among individuals over 65 years of age. PD has a prevalence of about 1% in people older than 60 years, reaching up to 4% in those over 80 years of age. AD and PD are highly disabling disorders with a slow but progressive course, caused by the degeneration and/or death of nerve cells. This results in impairments in the control of movement and balance, as in the case of PD, or in cognitive functioning, as in AD. To date, neither effective treatments nor early diagnostic tools are available to address these conditions in the initial phase of neurodegeneration. Likewise, there are no tools capable of monitoring disease progression and improving patients' adaptation to therapy. Moreover, although the association between T2D and the risk of PD and/or AD has long been recognized, these conditions were historically considered unrelated. Recent evidence from clinical and epidemiological studies suggests the existence of shared pathophysiological mechanisms associated with insulin resistance and persistent inflammation in several metabolically relevant tissues, such as adipose tissue and the brain. However, the mechanisms that increase the risk of PD and/or AD in individuals with T2D remain poorly understood. These data highlight how relevant these diseases are for the National Health System and demonstrate that they represent one of the most important priorities to be addressed, requiring substantial investments in both scientific research and early diagnostic strategies. Therefore, the present project proposal, which aims to develop new minimally invasive tools for the early prediction and monitoring of neurodegenerative diseases such as AD and PD, will help fill an important gap in the clinical and therapeutic management of these patients.
