NCT05741853
Difficulties with speech and language are the first and most notable symptoms of primary progressive aphasia (PPA). While there is evidence that demonstrates positive effects of speech-language treatment for individuals with PPA who only speak one language (monolinguals), there is a significant need for investigating the effects of treatment that is optimized for bilingual speakers with PPA. This stage 2 efficacy clinical trial seeks to establish the effects of culturally and linguistically tailored speech-language interventions administered to bilingual individuals with PPA. The overall aim of the intervention component of this study is to establish the relationships between the bilingual experience (e.g., how often each language is used, how "strong" each language is) and treatment response of bilinguals with PPA. Specifically, the investigators will evaluate the benefits of tailored speech-language intervention administered in both languages to bilingual individuals with PPA (60 individuals will be recruited). The investigators will conduct an assessment before treatment, after treatment and at two follow-ups (6 and 12-months post-treatment) in both languages. When possible, a structural scan of the brain (magnetic resonance image) will be collected before treatment in order to identify if brain regions implicated in bilingualism are associated with response to treatment. In addition to the intervention described herein, 30 bilingual individuals with PPA will be recruited to complete behavioral cognitive-linguistic testing and will not receive intervention. Results will provide important knowledge about the neural mechanisms of language re-learning and will address how specific characteristics of bilingualism influence cognitive reserve and linguistic resilience in PPA.
NCT05732285
The purpose of this study is to examine the feasibility of comprehensive multimodal individually tailored Cognitive Behavioral Therapy (CBT), Cognitive Rehabilitation Therapy (CRT), and modifiable lifestyle sessions. The study team hypothesizes that combining evidence-based cognitive and affective therapies with lifestyle modifications is feasible and will improve the community integration (CI) and Quality of life (QoL) in patients with a neurocognitive disorder compared to usual care.
NCT07205003
The mechanical behavior of conductance arteries is viscoelastic. While the elastic component has been extensively studied, the viscous component has often been neglected for methodological reasons and also because it was considered weak. Unlike a purely elastic solid, which exhibits instantaneous deformation/relaxation upon application/discontinuation of a force, a viscoelastic solid is characterized, from a mechanical point of view, by a delay between the application or discontinuation of the force and deformation. Thus, at the arterial level, the elasticity of the arterial wall allows the internal diameter to increase proportionally to the blood pressure during systole. The viscous component will induce a delay in diameter restoration, resulting in a larger diameter at each pressure level during the diastolic phase compared to the systolic phase. This results in a shift between the systolic and diastolic curves of the pressure-diameter relationship, creating a hysteresis loop. From a thermodynamic point of view, while a purely elastic material fully restores the energy stored during the loading phase, viscoelastic arteries will incompletely restore this energy. Thus, the surface of the hysteresis loop reflects the energy dissipated during each cardiac cycle (WV), and the area under the loading phase curve represents the energy stored by the arterial wall (WE) during the latter. Thus, arterial wall viscosity (APV) can be expressed either as the absolute value of WV or as a function of the stored energy (WV/WE). Physiologically, this energy loss is low. Its increase could be accompanied by excessive energy dissipation, leading to increased cardiac work and cardio-circulatory decoupling. Conversely, low parietal viscosity could lead to damage to peripheral organs by excessive transmission of pulsatile energy to the periphery due to lack of damping.
NCT05318976

NCT06463093
The aim of the research is to analyze whether 18F-FDG PET helps in the diagnosis and therefore in the management of the patient.
NCT04761458
The aims of this research project are to evaluate whether global olfactory impairment is a reliable indicator of preoperative frailty and cognitive impairment, and whether it may predict postoperative neurocognitive disorders, morbidity and mortality in a population of older patients scheduled for elective intermediate- to high-risk elective surgery. 1. We will measure preoperative global olfactory function (threshold, discrimination, identification) and evaluate whether olfactory impairment predicts preoperative frailty (using the Edmonton Frail Scale, the Clinical Frailty Scale and handgrip strength) and postoperative complications and mortality. 2. We will address the question whether preoperative olfactory impairment may be associated with a preoperative cognitive impairment (through a neuropsychological test battery) and whether it may predict a decrease in postoperative neurocognitive function.
NCT03628768
The study evaluates the association between the neurocognitive decline and falls.
NCT05094817
Delirium is common in older adults after inpatient surgery and may be associated with cognitive decline. Advances in surgical and anesthetic techniques have led to increasing numbers of older adults undergoing surgery on an outpatient basis. However, few studies have investigated cognitive disorders of older adults before or after ambulatory surgery. Increased age and pre-existing cognitive impairment are strong risk factors for cognitive decline after surgery, yet older adults are not screened for cognitive impairment before surgery. Existing screening tools require specially trained staff for test administration and in-person testing. Virtual cognitive screening has not been evaluated in surgical patients. In this study, investigators will determine the feasibility of using Cogniciti's Brain Health Assessment (BHA) - a validated online cognitive screening tool that can be self-administered from a patient's home before surgery - to screen older adults before ambulatory surgery.
NCT06372002
This study aims to evaluate the effectiveness and cost-effectiveness of CST-ES, the Spanish adaptation of Cognitive Stimulation Therapy (CST), to improve cognition and quality of life in people with mild to moderate dementia. The evaluation will be conducted as a pragmatic multicenter randomized controlled clinical trial. Participants will be randomized to receive 7 weeks of CST-ES followed by 24 weeks of maintenance CST-ES (intervention group) or to continue their usual treatment (control group).
NCT06036095
Traditionally, general anesthesia is maintained with inhalational anesthesia (GAS), but there is a gap in knowledge regarding whether intravenous anesthesia (IV) can prevent deleterious postoperative outcomes in the geriatric surgical population. The goal of this clinical trial is to determine whether intravenous anesthesia (IV) leads to a decreased incidence of postoperative delirium (POD), postoperative cognitive dysfunction (POCD), and functional decline, and improved patient-reported outcomes (PROs) in older adults undergoing non-cardiac surgery when compared to the standard inhalational anesthesia (GAS). This single-center, 1:1 randomized, double-blind (patient \& outcome assessor) clinical trial will compare inhalational vs. intravenous anesthesia on POD, POCD, functional status, patient-reported outcomes (PROs), and blood-based biomarkers in older patients undergoing elective, inpatient, non-cardiac surgery. Upon enrollment, 260 women and men ≥ 70 years undergoing elective noncardiac surgery under general anesthesia will be randomized to 2 groups: TIVA or GAS.
NCT04210713
The objective of this proposal is to advance medication development for alcohol use disorder by examining the efficacy and mechanisms of action of minocycline, a neuroimmune modulator, as a potential treatment. This study has important clinical implications, as the available treatments for alcohol use disorder are only modestly effective and testing novel medications is a high research priority.
