PD is the second most prevalent neurodegenerative disease. Globally, the burden of PD has doubled as a result of the increase in the number of older people. The prevalence of PD is estimated to be 6.2 million people worldwide, although the European Parkinson's Disease Association (EPDA) suggests that the figure should be higher, at around 10 million people, due to under-diagnosis [10]. Some studies suggest that this figure could double by 2040 to 12 million [11]. The estimated annual European cost of Parkinson's disease is EUR 13.9 billion, representing EUR 1600 per patient [12]. People with CVD have one or more risk factors, such as high blood pressure, diabetes, or hyperlipidemia. Early detection of disease aggravation and prompt treatment is essential [13]. CVD represented 31% of all global deaths in 2016, and it is deemed as the leading cause of premature death (37% of all deaths under the age of 70) and disability in Europe and worldwide [14]. The complications of chronic diseases can be influenced by several factors, some of which are modifiable and preventable if strategies are promoted among the population to improve health habits [15]. Lifestyle factors can influence the onset and intensity of chronic diseases [16; 17; 18]. People who lead a healthy lifestyle, such as eating a balanced diet, exercising regularly, having good sleep habits, and avoiding toxic intake, have many health benefits, especially in avoiding complications of chronic diseases [19; 20]. Providing patients with chronic diseases with a tool to help them manage their self-care may have important individual, clinical, and public health implications in view of the rapidly increasing trends in the prevalence of multimorbidity. Therefore, it is crucial to find new and innovative solutions to improve their quality of life (QoL), increase autonomy, and promote self-care with the ultimate goal of reducing the burden on European healthcare systems. The TeNDER project [21] is positioned to address this issue. The project aimed to create an integrated care ecosystem for people with chronic diseases, which adapted to their needs through a multisensorial system while preserving privacy and ensuring data protection. The TeNDER project was conducted in four different European countries and involved over 1500 users, including patients, health professionals, social workers, caregivers, and other staff. The project used affect-based micro tools to match clinical and clerical patient information and provided tailored integrated care services to promote well-being and health recovery. In addition, interactive communication and social services strengthened elderly support, extending their autonomy and care supply chain.
