Active clinical trials for "Cognitive Dysfunction"

Mild cognitive impairment is becoming one of the most common cynical manifestations that affect older people. That is why there is a need to investigate non-pharmacological interventions that help to improve or maintain this problem.

Cognitive dysfunction is the impairment of mental process of perception, memory and information processing which allow the human to acquire knowledge and plan for the future . The etiology of Postoperative cognitive dysfunction (POCD) is unclear and seems to be multifactorial involving a combination of patient, surgical, anesthetic and environmental factors .It can be a manifestation of transient or permanent cerebral injury. While cognitive function tends to improve over months to years postoperatively in affected individuals, some proportion has seemingly permanent cognitive injury .

The population is increasingly older and this means that there are more and more dependent older people, for this reason it is necessary to achieve the best quality of life for the older adult population by promoting active and healthy aging.

The drug, scopolamine, can result in short-term impairments of cognitive function, attention, and memory that resemble those seen in aging and Alzheimer's disease. This study tested the capability of both individual and combined doses of MK-3134 and the current standard treatment: donepezil (Aricept), to reverse such impairments, following a single dose of scopolamine. Participants were evaluated after each of 5 different treatment periods (in a cross-over, double-dummy design): A: placebo to match both donepezil (oral [PO]) and MK-3134 (PO) followed by placebo scopolamine (subcutaneous [SQ]); B: placebo to match both donepezil (PO) and MK-3134 (PO), followed by scopolamine SQ; C: MK-3134 (PO) followed by scopolamine SQ; D: donepezil (PO) followed by scopolamine SQ; E: MK-3134 (PO) and donepezil (PO) followed by scopolamine SQ. The doses of MK3134, donepezil, and scopolamine were the same over all treatment arms in which the specified drug was administered. There were 8 total visits for each treatment period, including 5 Treatment Visits requiring 14-day intervals between visits for study-drug washout. Participants were assessed for cognitive function before and after each treatment period during the Treatment Visits.

There will be a significant difference in cognitive function between cognitive intervention group (group therapy) and a wait list control group. There will be a significant difference in cognitive function between a home-based cognitive intervention group and a wait list control group.

This study is a six-week, randomized, placebo-controlled, fixed dose trial comparing cannabidiol Vs. placebo added to a stable dose of antipsychotic medications in patients diagnosed with schizophrenia.

Exploration of repetitive transcranial magnetic stimulation（rTMS）on working memory and cognitive impairment symptoms of schizophrenia treatment and mechanism. Analysis of high-frequency repetitive transcranial magnetic stimulation stimulation to the improvement of negative symptoms and psychotic symptoms.

Computer-Based Cognitive Training for Individuals with Parkinson's Disease" is a 3-arm randomized controlled trial (RCT) comparing Brain Fitness, InSight, and an active control (AC) training program to evaluate the feasibility of empirically supported computer-based cognitive training programs (CCTPs) for patients diagnosed with Parkinson's disease (PD) with Mild Cognitive Impairment (MCI). This pilot study aims to address the need for increased interventions to target non-motor symptoms associated with PD.

Some studies reported that selenium status is associated with cognitive function. However only a few reports have investigated whether selenium supplementation can benefit cognitive performance and in most of them selenium supplementation was not exclusive. Also, none of those reports have used foods rich in selenium as a source of supplementation. Thus, the aim of our study was to investigate whether the consumption of Brazil nuts improves cognitive function. We hypothesized that the daily consumption of Brazil nuts would have benefits on selenium status, increase antioxidant enzyme activity and improve cognitive function in older adults with MCI.

Akershus Cardiac Examination (ACE) 1950 Study is a large, observational, prospective, longitudinal, population-based cohort study. The overall aim is to establish an extensive cardio- and cerebrovascular age cohort of elderly subjects for various longitudinal long-term follow-up studies of cardiovascular and cerebrovascular disease.
