Cognitive Assessment

The incidence of stroke increases every year throughout the world. Neuropsychological assessment is the best way to identify post-stroke cognitive dysfunction. The importance of cognitive function in the post stroke rehabilitation program process requires a tool that can detect cognitive disorders more specifically and more sensitively. The investigator aim in this study was to develop Indonesian version of the OCS - Plus among stroke patient in Indonesia.

This project will investigate whether daily snack consumption can improve memory, mood, and overall brain function in people with cognitive impairment. Sixty participants, aged 50 and older, with cognitive impairment, will be randomly assigned to eat snacks, either pecans or pretzels, for three months. Researchers will also study how snacks (pecans and pretzels) may influence the body, including changes in gut bacteria, blood markers of inflammation, and signals that connect the gut and the brain.

The investigator's objective is to explore the definitive evidence of mushroom on cognitive functions among at-risk middle-aged and young-olds. The investigator carefully designed a randomized controlled trial (RCT) to assess the role of mushrooms in promoting cognitive functioning among around 600 middle-aged adults and young-olds. Participants were selected based on specific inclusion criteria, such as being community-living adults aged 45-80 years with a family history of dementia or subjective cognitive decline, while consuming mushrooms no more than once a week and having no dementia, along with the exclusion of individuals with neurological or psychiatric disorders and significant sensory or motor impairments. Participants in the intervention group will consume Pleurotus citrinopileatus mushroom powder daily for 24months, with compliance

The proposed project will evaluate the synergistic effects of a nutritional formulation, 'Think Tank' on cognitive performance following exposure to a psychological and physical stressor. Adopting a double-blind repeated measures cross-over design, middle-aged females (40-60 years) will be recruited to take part in a two-stage research study that will examine whether the formulation enhances cognitive performance and subjective well-being following the challenge of a stressor, compared to placebo. Cognitive assessments will examine the impact of the nutritional formulation on working memory, sustained attention, cognitive flexibility and inhibitory control. The study will also assess physiological (heart rate, blood pressure and cortisol) and subjective (well-being, anxiety, positive and negative mood, stress) markers of stress reactivity. The study will also explore levels sleep quality, mental and physical fatigue, effort, productivity, and perceived impact of the intervention.

This study investigates the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on cognitive performance in healthy adults. The study uses a sham-controlled, cross-over design in which each participant receives both active taVNS and sham stimulation in separate sessions. Each participant completes both conditions (active and sham) in a randomized order using a crossover design. Cognitive performance will be assessed before and after each session using standardized tests. The study also explores whether males and females respond differently to taVNS, in order to identify potential sex-related differences in cognitive outcomes.
