Active clinical trials for "Cognitive Dysfunction"

This study is designed to determine whether memantine is an effective treatment for memory and cognitive problems associated with multiple sclerosis when compared to placebo.

This is a single center, non-blinded randomized control trial taking place at the Queen Elizabeth II hospital (QEII) in Nova Scotia. Patients are eligible if aged 75 and older scheduled for elective cancer surgery and screened as severely frail or cognitively impaired. Participants will then be randomized to preoperative standard of care or geriatric assessment through the PATH clinic. Primary outcome will assess time spend at home at 6 months after the surgery.

The purpose of this study is to investigate the effect of the dual task exercise program on cognitive and physical function in the elderly with mild cognitive impairment.

to assess executive network using resting-state fMRI and patterns of brain activation using task fMRI with a cognitive paradigm, against the background of taking the drug in comparison with placebo in patients with post-COVID asthenic syndrome.

This study investigates the utility of Goal Management Training (GMT) in patients with post-traumatic stress disorder (PTSD), in order to determine if this treatment is effective in improving cognitive function in patients with frontal-temporally mediated brain dysfunction. Specifically, the primary aim of this study is to examine whether a standardized 9-week program of GMT results in durable improvements in cognitive functioning relative to a wait-list control group. A secondary aim will be to determine whether participation in the GMT group is associated with long-term functional improvements. It is hypothesized that at post-treatment, participants with PTSD assigned to the GMT groups will show greater improvement in neuropsychological test performance and greater functional improvement compared to those in the wait-list group; these gains are expected to be maintained at 3 month follow-up.

The patients with type 2 diabetes mellitus (T2DM) is expected to rise to 439 million in 2030, accounting for 7.7% the population in the world. There are nearly 10 million T2DM patients with mild cognitive impairment (MCI) among people over 65 years old , accounting for about 8% of the people over 65 years old in China. The medical cost for patients with T2DM/MCI is 2.5 to 4 times higher than those without T2DM. And T2DM will increase the risk of cognitive impairment, and lead to various complications which will bring serious social and medical economic burden.

The aim of the intervention proposed in the present study is to assess the effect of a cognitive stimulation (CS) intervention program in an individual and long-term format, for non-institutionalized elderly people with neurocognitive disorders and in a situation of social vulnerability. Specifically, to test the effectiveness of CS on the global cognitive state, on mood state, on quality of life and on functional state. The program will be composed by 50 sessions, including three of assessment sessions (pre, intra and post-intervention). Each session will have a duration of 45 minutes with a weekly frequency. Control group participants will maintain their treatment as usual.

The investigators propose to apply neuroplasticity-based computerized cognitive remediation (nCCR) to treat chemotherapy-related cognitive impairment (CRCI).

Mild cognitive impairment (MCI) is a transitional state between normal cognitive decline and dementia. Individuals with MCI are having an impairment in cognitive function compared with normal age-matched counterparts, while their cognitive function is still sufficient for their daily function. The prevalent rate of MCI is ranging from 10% to 20%. Patients with MCI are more susceptible to dementia with annual conversion rate between 5% and 20%. It is well-known that dementia not only lead to devastating consequences to the patients and their care-givers, but also immense healthcare and socioeconomic burdens. The growing prevalence of MCI in our rapidly aging population warrants immediate action to identify effective interventions to prevent progression of the cognitive impairment and its conversion to dementia. Currently, there is no pharmaceutical treatment proven to be effective in alleviating the cognitive decline in MCI patients. Nonetheless, previous researches have demonstrated that mind activity, physical exercise and social engagement are all have positive effects in alleviating the cognitive decline in MCI patients. Tai Chi is a traditional form of Chinese mind-body exercise that consists of both physical exercise and meditation component. Practicing Tai Chi can also facilitate social engagement as people usually practice in group. Tai Chi is expected to be more acceptable to the older adults for incorporating it with their daily life to preserve cognitive function, compared with conventional physical activity modalities (e.g., running/jogging and gym-based resistance training). Preliminary evidences suggest the potential of Tai Chi for alleviating cognitive decline in older adults. A randomized controlled trial is needed to conclude on the therapeutic use of Tai Chi before it can be large-scale implemented at community level. This study seeks to extend previous findings of the beneficial effects of Tai Chi on cognitive function in older adults with MCI and examine the impact of Tai Chi training in protecting older adults with MCI from developing dementia. This study also attempt to delineate the behind mechanism of Tai Chi on alleviating cognitive decline by including measurements in neuroimaging and blood markers.

There is accumulating evidence suggesting that Aloe vera and Crocus (saffron) may have a positive impact on conditions involving cognitive deficits, such as Mild Cognitive Impairment (MCI) and AD. More specifically, aloe vera gel contains powerful antioxidants, which belong to a large family of substances known as polyphenols. Aloe has also been proven to possess cholinergic and cognitive enhancing capabilities. Crocus is deeper studied and it shows promising results in neuroprotection against AD through various suggested mechanisms, such as the enhancement of amyloid-beta clearance in the brain and the inhibition of neurofibrillary tangles formation. For this reason, it would be interesting to study the effects of combination of Aloe Vera and Crocus . The aim of the study is to evaluate the beneficial effect of Aloe Vera and Crocus (saffron) in comparison with Aloe (simple)on patients diagnosed with mild cognitive impairment MCI.
