Active clinical trials for "Cognitive Dysfunction"

The purpose of this study is to integrate advanced computational techniques and multimodal neuroimaging methods to examine the potential effects of long-term, multi-domain, online, computerized cognitive training on large-scale structural and functional brain networks in older adults with mild cognitive impairment (MCI).

Patients receiving beach chair position shoulder surgery are vulnerable to perioperative cerebral desaturation, which is reported to be a risk factor for postoperative cognitive dysfunction. Investigators design this study to test the efficacy of perioperative goal-directed therapy in preventing cerebral desaturation and postoperative cognitive dysfunction in patients receiving beach chair position shoulder surgery.

This study will aim to identify the impact of Intraoperative dexmedetomidine infusion on POCD assessed by the Montreal Cognitive Assessment (MoCA) in geriatric patients above 60 years undergoing hip surgery under spinal anaesthesia.

This research study will evaluate the effectiveness and estimate the feasibility of administering an investigational drug called 'CN-105' (the study drug), to prevent postoperative cognitive decline, delirium (serious confusion) and underlying brain inflammatory and brain activity changes in adults 60 years and older undergoing surgery.

This study will investigate an intervention delivered by community health workers for older adults with signs of cognitive impairment, mobility loss, and depression in the rural primary care setting.

This longitudinal study aims to countervail age-related cognitive and cerebral decline in healthy retired people through intensive piano / keyboard music practice in Switzerland and Germany.

Background: 36% of the Italian population will have more than 65 years in 2050. The European Union has indicated among its priorities to increase research on active aging. Physical activity contrasts disability linked to chronic diseases, has positive effects on the quality of life and on biological rhythms, prevents the decline of motor functions, improves the immune response, and prevents / positively affects metabolic disorders. It also provides valuable support in coping with cognitive decline and memory, and acts on depressive symptomatology. The literature on active aging is based, to date, on studies with small samples, rarely conducted with a randomized controlled method, whose outcomes often appear contradictory. The multidisciplinary project the investigators propose is an opportunity to address the issues mentioned above and to acquire further knowledge in the field of active aging. Objectives: the main objective of the study is to evaluate the effects of mild-to-moderate physical activity in a sample of over-65 years-old persons, on Quality of Life, and on biomechanical parameters (static-dynamic balance, mobility). The secondary objectives are aimed at assessing whether a protocol of mild-to-moderate physical activity can improve: Metabolic functions Cognitive performance Perception of pain Social rhythms and psychological wellbeing Inflammatory state Design: randomized controlled trial (RCT), single-blinded, with follow-up. Sample: participants will be ≥ 65 years old, of both genders, sedentary, enrolled in two arms through a random assignment (treatment/control) with ratio of 1:1, as following: about 60 subjects who will carry out a light-to-moderate physical activity intervention (experimental group); about 60 subjects in the control group, who will participate in group cultural activities (active comparison group). Assessment: the assessment will include socio-demographic variables; variables of psychophysical wellbeing; cognitive variables; variables related to physical health; biomechanical variables; assessment of skin integrity; lab tests on blood samples. Times of evaluations: both groups will be subjected to the measurements of the present study according to the following schedule: T0 (baseline): before the start of the intervention T1: 12 weeks after T0 (at the end of the intervention) T2: after 20 weeks from T0 (follow up 1) T3: 48 weeks after T0 (follow-up 2).

The objective of this study is to evaluate the efficacy of a NeuroQ supplement designed by Dr. Bredesen to complement his Lifestyle modification protocol. Eligible participants will be expected to consume the NeuroQ supplement and are recommended to make lifestyle changes based on Dr. Bredesen's protocol. Forty participants are expected to enroll into the study, completing study assessments at check in visits days 30 and 60, and at the end of study visit on day 90. A brief follow up phone call will be conducted approximately 30 days after study completion to ask participants if they have continued using the lifestyle changes and if they have purchased and continued to consume the NeuroQ supplement.

Computerized cognitive interventions (CCIs) have been increasingly widely implemented among older adults with mild cognitive impairment (MCI). However, the efficacy of CCIs in maintaining or improving older adults' cognitive and functional health has been modest and highly variable. Older individuals' attitudes toward technology use may help explain some of the variability in CCI effects. The goal of this R21 is to generate proof-of-concept for an intervention that may improve attitudes toward computers among those with MCI, in turn improving engagement with and efficacy of a subsequent CCI. Person-centered care-that is, integrating individuals' preferences throughout the process of intervention--has improved intervention engagement among older persons, including those with MCI. A recent intervention predicated on this person-centered approach is called "personalized engagement program" (PEP). PEP involves a database of individualized computer-led leisure activities. The investigators' recent pilot data in senior living facilities suggest that PEP promotes psychological well-being among older persons with MCI, and may shift computers from dauntingly complex or personally irrelevant devices to familiar, enjoyable technology. These results are consistent with a number of theories indicating that exposure to pleasurable experiences with an object or task improves several dimensions of attitudes, including affective and cognitive components, as well as behavior and motivation. Grounded in both this pilot data and the theory around it, the investigators seek to take the next step in an arc of research ultimately intended to improve the efficacy of CCIs. A small randomized controlled trial (RCT) is proposed to assess whether an initial period of PEP, followed by a standard CCI, improves a) attitudes toward computers, b) engagement with the CCI, and c) cognitive outcomes, compared to an attention control period followed by CCI. Our design involving stratified random assignment of 50 assisted living residents with MCI from 4 senior living facilities to these two groups. The initial phase involves 4 weeks of either attention control or PEP, a "dose" suggested by prior work on attitude change and computers, followed by 6 weeks of CCI for both groups (a period our prior work indicates is sufficient for change in key cognitive domains among this population). This application is the first of which we are aware striving to augment CCIs, which are now ubiquitous, by addressing an attitudinal or affective element of the person, which are often ignored in the cognitive intervention literature. The adjuvant of PEP also answers increasing calls for "personalized" or "person-centered" behavioral interventions with older persons.

The investigators will conduct tau positron emission tomography (PET) scans on 125 adults using the radiopharmaceutical Flortaucipir F18 ([18F]AV-1451). This will allow the investigators to determine tau deposition across adults of different ages and assess the relationship of current tau burden to cognitive function and amyloid deposition collected over the previous 10-year interval.
