Within the scope of this study, COPD patients will be divided into two groups according to cognitive dysfunction. Pulmonary function test, COPD assessment scale, Mini-Mental State Examination and Montreal Cognitive Assessment Scale, 6 min pegboard ring test, grip strength measurement, Fatigue Impact Scale and St.George Respiratory Questionnaire will be applied to the groups.
Epilepsy is a common health problem worldwide. In general population, studies in developed countries estimated the annual incidence of epilepsy to be~50 per 100,000 and prevalence to be ~8.2 per 1,000. These figures are higher in developing countries in which prevalence of >10 per 1,000 was reported. In Upper Egypt, Assiut Governorate, the prevalence rate was 12.9 per 1,000. In people with epilepsy there is an associated high rate of cognitive difficulties that compromise educational progress and achievement throughout life. Approximately 1-5% of the population exhibits epileptiform discharges on electroencephalography (EEG). Interictal epileptiform discharges (IEDs), meaning spikes, polyspikes, sharp waves, or spike and slow-wave complexes without observed clinical seizures, are commonly observed in patients with epilepsy. Epilepsy syndromes manifesting with IEDs are detrimental to cognitive function. Recently, two studies found that frequent IEDs can impair cognitive performance in children. and adult patients. Several studies indicated that IEDs in patients with epilepsy had a disruptive effect on information processing speed with even a low percentage of IEDs (1%).However, it is unclear whether IEDs are associated with disrupted academic performance in patients with idiopathic epilepsy, and the relationship between general cognitive ability and academic performance in those patients has not been clarified. Understanding how IEDs interfere with neurocognitive outcomes is important ,while the goal of medical and surgical treatments for epilepsy is to achieve seizure-freedom with minimal morbidity, the benefits of IED suppression are more controversial.
Grounding (Earthing) refers to the practice of contacting the Earth or a properly installed grounding mat with the body. Previous studies on grounding have shown positive effects body-wide inflammation, acute and chronic pain, and immune system response. Prior studies on the inflammatory process of mild cognitive impairment due to Alzheimer's disease, Alzheimer's disease, and some other dementias have shown connections between immune system dysregulation, inflammatory markers, and severe disease progression. Finding ways to mitigate or turn off the inflammatory response is key to treating mild cognitive impairment due to Alzheimer's disease. The purpose of this study is to evaluate the effects of sleeping grounded on cognition and personal perceptions in participants with a diagnosis of mild cognitive impairment due to Alzheimer's disease as evidenced by a battery of assessments using Cogstate's Cognitive Brief Battery and a qualitative questionnaire. We hypothesize that assessment scores will improve with grounding and that perceptions will positively correlate with an increase in scores. Modulation of risk factors like glucocorticoid resistance, SCI, and immune system dysfunction through grounding may lead to an accessible, natural technique for neurodegenerative disease prevention or treatment.

Aging-related cognitive decline may be affected by brain cholesterol and the health of cell membranes. Certain nutritional supplements have been proposed to support membrane health, and there is increasing interest in plasmalogens and Omega-3 derived oil supplements to support brain health among older adults. Plasmalogens are compounds found in neural cell membranes that are connected to cholesterol processing. Neural cells that have low plasmalogens have shown an inability to process cholesterol properly. Recent research suggests that abnormalities in cholesterol processing and low levels of plasmalogen may play a role in age-related cognitive decline. The product being investigated in this study is the ProdromeNeuro Omega 3 oil nutritional supplement. This product contains naturally occurring fatty acids in higher concentrations than similar products that are commercially available. The purpose of this research study is to better understand the effects of ProdromeNeuro Omega-3 nutritional supplementation among participants with age-related cognitive decline. It is hoped that taking this product over the course of 4 months will result in improved plasmalogen levels, brain connectivity seen on advanced brain imaging, as well as improved cognitive assessment measurements.
The SNIFF 3-Week Aptar Device study will involve using a device to administer insulin or placebo through each participant's nose or intra-nasally. Insulin is a hormone that is produced in the body. It works by lowering levels of glucose (sugar) in the blood. This study is measuring how much insulin the device delivers. In addition, this study will look at the effects of insulin or placebo administered intra-nasally using an intranasal delivery device on memory, blood, and cerebrospinal fluid (CSF).
The investigators aim to study the effects of a 24-week remote-based resistance exercise training program on cardiovascular disease risk factors, cognitive function, and quality of life in older adults living with mild cognitive impairment or Alzheimer's Disease and/or a related dementia. Data for this study will be collected at the beginning, middle, and end of the resistance training program. Participants of this study will receive a baseline health-fitness assessment at the beginning of the study. Measurements of resting blood pressure, fasting blood glucose and lipids, waist and hip circumferences, height and weight, cognitive function and quality of life will be collected at the health-fitness assessment. Participants will then receive supervised remote-based resistance exercise training with Therabands, 3 days per week for 12 weeks before receiving a second 12-week health-fitness assessment in the middle of the intervention. Participants will then receive 12 additional weeks of supervised remote-based resistance exercise training with Therabands, 3 days per week for 12 weeks before receiving a third 24-week health fitness assessment at the end of the study.
Transcranial Direct Current Stimulation is a non-invasive neuromodulatory technique that results in the clinical improvement of patients with Mild Cognitive Impairment, a prodromal condition for the onset of dementia. The responses to treatment depend on the characteristics of the patients and the parameters adjusted in the equipment, which makes the modeling of electric fields imperative to maximize the safety profile and therapeutic potential of the technique. The study of neurobiological predictors of response to non-invasive neurostimulation and genetic susceptibility can elucidate current effects according to the individual's profile. The objectives of this study are to observe the effects of Transcranial Direct Current Stimulation with optimized/customized parameters in patients with amnestic CCL, considering the subjects' genetic susceptibility to Alzheimer's Disease and neurobiological markers. This is a randomized, triple-blind, sham-controlled clinical trial. Neuropsychological tests and a sociodemographic and clinical questionnaire will be used to assess and characterize the subjects. Participants captured by the Laboratory of Studies in Aging and Neuroscience at the Federal University of Paraíba will be divided into 02 groups, each with 25 patients, totaling 50 volunteers: Active - participants who will receive real current; Sham - participants who will receive simulated stimulation. Participants entered through the eligibility criteria will be randomly allocated in a simple way, at a rate of 1:1. Payment parameters will be customized by Computational Modeling with the aid of the SimNIBS Program and Nuclear Magnetic Resonance. The electroencephalogram and evaluation of polymorphisms of the gene encoding Apolipoprotein E examined as predictors of response. Data will be processed from the Statistical Package for Social Sciences® (20.0) Software, applying the Student test for continuous variables or chi-square for categorical variables. Predictive analysis will be conducted from Machine Learning. It is expected to find improvements in the scores of memory and general cognition tests after the intervention protocol with tDCS with individualized dose in the group that will receive an intervention, compared to the simulated neurostimulation group. These obtained results optimize the practice, elucidating issues still present due to the different applications of the technique produced in the literature on the subject.
