Countervail Cognitive and Cerebral Decline in Mild Cognitive Impairment Patients Using Non-medical...

Mild Cognitive Impairment

Cognitive decline represents a major threat among the deleterious effects of population aging. The investigators propose to conduct an RCT (randomized controlled trial) on the subpopulation of MCI patients, and examine whether intensive musical or psychomotor group interventions can improve their cognitive and sensorimotor functioning, as well as induce brain plasticity, compared to a passive healthy control group, matched for age, gender and education level. The 2 training regimens will take place twice a week over 6 months and will be provided by professionals in each field.

Cognitive Outcome After Surgical and Transcatheter Aortic Valve Replacement

Postoperative DeliriumPostoperative Cognitive Dysfunction2 more

Aortic valve stenosis is one of the most common types of heart disease in the aging Western population. While surgical cardiac valve replacement (SAVR) is a standard therapy for patients with aortic stenosis, catheter-assisted aortic valve implantation (TAVI) has developed as an alternative to open-heart surgery, especially for high-risk patients. Recently, increased surgeon experience and improved transcatheter valve systems have led to a global trend to use TAVI in patients with low or intermediate risk. Although cognitive impairment after cardiac surgery is well known, the effect of TAVI on cognitive function has not yet been adequately investigated. The aim of this study is to compare the occurrence and progression of delirium, postoperative cognitive decline (POCD), cerebral infarction, and health-related quality of life (QOL) in patients with intermediate risk for catheter-assisted (TAVI) and surgical (SAVR) aortic valve replacement.

The Effects of Intermittent Theta Burst Stimulation in MCI and Early AD

Mild Cognitive ImpairmentAlzheimer Disease1 more

Transcranial magnetic stimulation (TMS) is a noninvasive brain stimulation technique that is increasingly used for a growing number of research and clinical applications.Typically, this transient magnetic field is focally applied with a figure-of-eight coil that is carefully placed on the surface of the scalp over a targeted stimulation site. Patterned repetitive TMS (rTMS), such as theta burst stimulation (TBS) can produce long-lasting effects on neural activity and behavior beyond the stimulation period (Chou et al., 2015a; Fitzgerald et al., 2006). In general, high frequency (> 5 Hz) rTMS and its newer version, intermittent theta burst stimulation (iTBS), facilitate cortical excitability, whereas low frequency (about 1 Hz) rTMS and continuous theta burst stimulation contribute to opposite effects (Pascual-Leone et al., 2000; Huang et al., 2005; Wassermann and Zimmermann, 2012).Careful manipulation of the parameters comprising these patterned rTMS pulse trains can induce neuroplastic changes that resemble either long-term potentiation (LTP) or depression (Chen et al., 1997; Pascual-Leone et al., 1994). Early studies targeting the motor cortex helped elucidate which rTMS parameters promote particular responses and their neurophysiological underpinnings (Klomjai et al., 2015). In recent years, rTMS has been closely investigated to evaluate its potential to modulate cognitive functions in Alzheimer'sdisease (AD) and mild cognitive impairment (MCI). As compared to conventional excitatory rTMS protocols, iTBS leads to comparable effects with similar number of pulses but considerable shorter duration and lower intensity of stimulation (Bakker et al., 2015; Rossi, Hallett, Rossini, Pascual-Leone, & Safety, 2009). Recent literature also suggest that TBS has lower rates of reported adverse event (AE) compared to rTMS (Najib & Horvath, 2014). Therefore, iTBS is assumed to modulate cognitive function in people with cognitive impairments.

Cognitive Impairment and Upper Extremity Performance in COPD

COPDUpper Extremity2 more

Within the scope of this study, COPD patients will be divided into two groups according to cognitive dysfunction. Pulmonary function test, COPD assessment scale, Mini-Mental State Examination and Montreal Cognitive Assessment Scale, 6 min pegboard ring test, grip strength measurement, Fatigue Impact Scale and St.George Respiratory Questionnaire will be applied to the groups.

INVESTIGATE THE ASSOCIATION BETWEEN VIRAL NEUROTOXIC INFECTION AND POSTOPERATIVE DELIRIUM AND POSTOPERATIVE...

POSTOPERATIVE DELIRIUM AND POSTOPERATIVE COGNITIVE DECLINE

In the last two decades, viral infections have increased dramatically : the 2003 severe acute respiratory syndrome coronavirus outbreak, the 2009 swine flu pandemic, the 2012 Middle East respiratory syndrome coronavirus outbreak, the 2013-2016 Ebola virus disease epidemic in West Africa and the 2015 Zika virus disease epidemic and not least the COVID-19 pandemic. At the same time, neurological disorders are a major and increasing global health challenge, which accounts for a substantial portion of the disease burden worldwide . In Europe, more than half of the population (approx. 60% ) suffers from a neurological disease, ranking number three among all disease groups . The figures are higher in the population with more than 65 years. Based on Eurostat annual publication "Aging Europe", in 2020 people over 65 represented 20.6% of the European Union population, and the projections show that the share of people over 65 is expected to strongly increase until 2058, reaching 30.3% of the EU population. Furthermore, while in civil aviation, the mortality rate is estimated around 0,00525% (Eurocontrol, 2022), the perioperative mortality rate in Europe is about 4% (Pearse et al., 2012). Clearly, the patients undergoing surgery already have a higher mortality risk depending on their initial medical conditions. However, the medical field can without doubts benefit from an improved risks assessment approach derived from the civil aviation. Against this backdrop, the project aims at: i) researching the correlation between a neurotoxic viruses' infection and the increased risk, in terms of frequency or severity, of developing a cognitive disfunction such as the postoperative cognitive dysfunction (POCD), by conducting an observational clinical trial on selected neurotoxic viruses (SARS-CoV-2, Herpes simplex virus, Cytomegalovirus and Epstein Barr virus). ii) developing a theoretical model for monitoring the implications of general anaesthesia in elder patients aged ≥ 65 years iii) designing a risk assessment mechanism, based on the best practices developed in the aerospace sector, for patients with neurotoxic infection and POCD, that can be furtherly scalable in other medical contexts. iv) building an AI-based platform, following the example of the NSQIP risk calculator for cardiovascular postoperative complications, both for data collection and data processing, able to return an estimate of the risk of perioperative-related cognitive complications in elder patients undergoing major elective surgeries. Observational Clinical Trial The clinical trial will recruit a sample of 1685 patients in eight centres (about 250 patients per centre, considering also the drop-out rate) to be finalised in 24 months. The primary end point of the clinical trial is to evaluate if patients undergoing general anaesthesia for elective major surgeries lasting longer than 1 hour that have an history of COVID-19 (not an active SARS-CoV-2 infection) do have a higher risk to develop postoperative cognitive dysfunction (POCD)/delayed neurocognitive recovery (DNC) at 3 months and 6 months follow up after surgery. Secondary end point include: - Relationship between POCD/DNC with preoperative exposure to other neurotropic viruses: Herpes simplex virus (HS), Cytomegalovirus (CMV), and Epstein Barr virus (EBV). - Development -on the basis of collected data- of a software dedicated to calculating in the preoperative phase the risk for early postoperative delirium or POCD/PNDs. - Development of a conceptual model of "perioperative safety management": as in civil aviation traffic control, increasing the patients' perception of healthcare safety and quality. - Delivery of training to healthcare practitioners concerning the preoperative evaluation of POD risk and the identification of patients at risk.
