Filter by:The overarching goal of this UH2-UH3 proposal is to work with the NIH Health Care Systems Research Collaboratory to develop and implement a large scale, cluster randomized pragmatic clinical trial demonstration project that directly informs national trauma care system policy targeting injured patients with presentations of Posttraumatic Stress Disorder (PTSD) and related comorbidity. Each year in the United States (US), over 30 million individuals present to trauma centers, emergency departments, and other acute care medical settings for the treatment of physical injuries. Multiple chronic conditions including enduring PTSD, alcohol and drug use problems, depression and associated suicidal ideation, pain and somatic symptom amplification, and chronic medical conditions (e.g., hypertension, coronary artery disease, diabetes, and pulmonary diseases) are endemic among physical trauma survivors with and without traumatic brain injuries (TBI). Evidence-based, collaborative care/care management treatment models for PTSD and related comorbidities exist. These care management models have the potential to be flexibly implemented in order to prevent the development of chronic PTSD and depressive symptoms, alcohol use problems, and enduring physical disability in survivors of both TBI and non-TBI injuries; care management models may also be effective in mitigating the impact of the acute injury event on symptom exacerbations in the large subpopulation of injury survivors who already carry a substantial pre-injury burden of multiple chronic medical conditions.
This study will recruit surgical patients more than 65 years old. Patients who participate will wear a sticker on their forehead during surgery which monitors their brain waves (electroencephalogram, EEG) and participate in memory testing before and after surgery. Brain wave patterns will be compared between patients who have problems with memory and thinking after surgery and those who do not. The hypothesis is that there will be characteristic brain wave patients for who will go on to have problems with memory and thinking after surgery.
A prospective observational multicenter study aiming to describe incidence, and identify predictors for development of poststroke dementia (PSD) and mild cognitive impairment (MCI) after stroke
The purpose of this study is to develop pilot data on the potential efficacy of computer-based cognitive training or the combination of computer-based cognitive training with transcranial direct current stimulation (tDCS) in improving cognitive function in persons with HIV-related mild neurocognitive disorder (MND).
This study is intended to investigate the safety of candesartan, a blood pressure medication, in non-hypertensive individuals who have mild cognitive impairment (MCI) due to Alzheimer's disease and its effect on disease biomarkers.
The purpose of this study is to determine whether the chinese medicine Jian Pi Yi Shen Hua Tan granules is effective in the treatment of cognitive impairment after acute cerebral infarction .
This study evaluates the efficacy and mechanism of internet-based cognitive training in patients with subcortical VCIND. Half of participants will receive multi-domain adaptive internet-based training program, while the other half will receive a fixed, primary difficulty level task.
Parkinson's disease (PD) is known for its motor symptoms and affects more than 100,000 Canadians. However, PD patients also show cognitive deficits and neuropsychiatric problems that significantly impair their quality of life. The occurrence of dementia in PD is much higher than in the general population. The proposed study will allow the principal investigator, his team and his collaborators to investigate the origins and evolution of the cognitive and neuropsychiatric symptoms. Participants with PD with and without mild cognitive impairment (MCI) and participants with and without MCI over the age of 60 years will be assessed during eight study visits over three years. Through brain imaging, clinical testing, as well as genotyping the cognitive patterns in the four different groups will be observed and compared. The results will be used to identify biomarkers that can predict the occurrence of dementia early in the disease. Ultimately, the results of the proposed research will contribute to interventions and treatment strategies tailored to different cognitive profiles in PD before the occurrence of dementia.
The purpose is to is to study if repetitive transcranial magnetic stimulation (rTMS) improves cognitive function in patients with neurodegenerative conditions which may manifest as mild to moderate cognitive impairment and, in late phase, dementia. This study also intends to investigate if the responses to rTMS intervention are either positively or negatively correlated with the initial severity of cognitive impairment.
The current study aims to validate several novel cognitive tasks expected to be sensitive to brain impairment in specific anatomic regions affected in preclinical Alzheimer's disease(pAD). The tasks are validated in 60 cognitively and clinically normal participants ages 60 - 85, inclusive, against reasonably well-established biomarkers of Alzheimer's disease, including 1) simultaneous positron emission tomography (PET) [18F]Flutemetamol amyloid and CT imaging and 2) to the extent data is available from other studies, participants' brain MRI and cerebral spinal fluid (CSF) amyloid and tau.
