Active clinical trials for "Cognitive Dysfunction"

Advance care planning among patients with cognitive disorders poses unique challenges to clinicians. To improve planning in patients with Alzheimer's disease and other dementias, the researchers suggest a routine, standardized approach to these conversations. The main outcome measure is the rate of entry of Advance Directive completion in the patient's Electronic Health Record (EHR). A control group of similar patients from another provider specializing in cognitive disorders will be used to tease out confounding variable effects.

This research investigates obesity and associated psychiatric symptoms and disorders in a wide range of perspectives, to demonstrate the effects of obesity on the brain. The 1st aim is to assess the psychiatric symptom profiles in the group of obese patients applying for bariatric surgery and to determine the associated environmental stress factors. While, it is known that eating disorders, mood disorders and psychiatric drugs can cause obesity, obesity can also cause many psychiatric complications such as depression and cognitive disorders. There are no multi-centered studies that are conducted in this respect, and the guidelines on pre-evaluation and follow-up of patients are also lacking. The 2nd aim is to evaluate and monitor cognitive characteristics before and after bariatric surgery in obese patients. Obese people are at increased risk of dementia and are more likely to have cognitive deficits, especially executive function problems, that can affect everyday life. For this reason, obese individuals should be examined and monitored in more detail in terms of their cognitive characteristics and the change of cognitive functions during the weight loss process. The 3rd aim is to examine the relationship between obesity, bariatric surgery and reward processing system. Studies have been limited in determining whether addiction in these people is due to a search of a continuous substance as a cognitive feature or whether it is difficult to terminate it as an impulsive behavior when encountered with a pleasurable substance, even though there is no reward seeking or reward dependence. The 4th aim is the determination of the neuroanatomical and molecular components of cognitive changes observed after bariatric surgery. During the dynamic process following bariatric surgery, a variety of metabolites, chemokines, and microbiota changes may also affect the brain health and cognition. The 5th aim is to determine factors of eating, emotional regulation, reward system, addiction and impulsivity, and other psychopathologies that cause suboptimal weight loss or weight gain after bariatric surgery. Understanding the psychological and neurobiological factors involved in these processes can improve surgical interventions and significantly increase the quality of life for patients.

Advance care planning (ACP) has been widely advocated for persons with early stage dementia (PWEDs) and persons with mild cognitive impairment (MCI). This proposed study attempts to promote the uptake of ACP for this population and their family caregivers in the community and to examine the effects of an ACP programme "Have a Say" for this population. It is hypothesized that participants received the intervention will be more engaged in ACP and their dyadic concordance on end-of-life care preference with their family caregivers will be higher after the intervention.

Cognitive impairment may cause problems in planning and initiating daily activities, as well as remembering to do what is scheduled. This study investigates the effectiveness of an interactive web-based mobile reminder calendar, (RemindMe). The calendar sends text messages to the user's mobile phone as support in everyday life, for persons with cognitive impairment due to neurological injury/diagnoses. The study has a randomized controlled trial design with data collection at baseline and at follow-up sessions after two and four months. Data collection started in October 2016 and continued until February 2018. RemindMe may give the needed support to remind the person and thus increase the ability to perform activities and to become independent in everyday life.

Cataract surgery is commonly performed in elderly patients who are at high risk for developing postoperative cognitive dysfunction. Most cataract surgeries are performed under peribulbar or retrobulbar anesthesia, however, most of the patients require sedation to relieve the perioperative anxiety and induce amnesia. So, many sedative agents can be used especially benzodiazepines which may increase the risk of developing postoperative cognitive dysfunction. Ketamine can be used as a sedative and analgesic agent in a dose of 0.25 -0.5 mg/kg with certain studies suggesting that it may decrease the risk of postoperative cognitive dysfunction. Similarly, dexmedetomidine can be used as a sedative and analgesic agent with the possibility of decreasing the incidence of postoperative cognitive dysfunction. this controlled study will compare the effect of ketamine or dexmedetomidine on the POCD of patients undergoing cataract surgery.

Previous cross-sectional studies have shown that informing cancer patients about potential chemotherapy-related cognitive symptoms may negatively affect perceived cognitive symptoms and verbal memory performance. A multicenter, randomized study in newly diagnosed breast cancer patients receiving (neo) adjuvant chemotherapy was performed to evaluate this Adverse Information Effect (AIE) over time and investigated whether inviting patients to self-affirm can reduce such AIEs on perceived cognitive symptoms and cognitive test performance.

The aim of this study was to compare the effects of three months' endurance training and three months' endurance-strength training on selected psychological aspects in women with abdominal obesity.

The goal of this study is to refine and test a strategy for engaging older adults with symptoms of SCD/MCI (subjective cognitive decline/mild cognitive impairment) as volunteers to help English language learners (ELLs) who live in the US improve their speaking skills via structured conversations using videoconferencing.

The purpose of this study was to determine the effect of dairy-based probiotics on cognitive function, emotional wellbeing, and inflammation. Subjects were assigned to either consume 6 oz of yogurt/day or abstain from consuming yogurt and other probiotic-containing foods for 12 weeks. Subjects completed baseline testing and 12-week follow-up testing consisting of a laboratory blood draw to assess inflammatory biomarkers, and a computerized assessment to evaluate cognitive and emotional wellbeing measures.

Advance care planning (ACP) has been widely advocated to persons with early stage dementia (PWEDs). This feasibility trial aims to test a theory-based ACP programme "Have a Say" specifically designed for this population, which is underpinned by the Bandura's self-efficacy model. It is the first of its kind in Hong Kong and will be conducted in the community through medical-social collaboration. The aim of this study is to test the feasibility and preliminary effects of the "Have a Say" programme. It is hypothesized that participants in the intervention group will be more engaged in ACP and their dyadic concordance on end-of-life care preference with their family caregivers will be significantly higher than that in the control group.
