Filter by:The invesigators propose a clinical study on patients undergoing carotid surgery (endarterectomy). The invesigators will determine carotid artery imaging features associated with (1) vessel wall inflammation, (2) downstream brain inflammation, and (3) cognitive benefit from surgery. This project will uncover links between inflamed carotid plaque and downstream brain inflammation. The invesigators will also determine carotid plaque imaging features predicting cognitive benefit from carotid surgery.
The present collaborative R01 study, between Cornell and Johns Hopkins, aims to compare Problem Adaptation Therapy for Mild Cognitively Impaired Older Adults (PATH-MCI) vs. Supportive Therapy for Cognitively Impaired Older Adults (ST-CI) in improving cognitive, affective, and functioning outcomes.
In this Austrian observational study preterm infants born with a birth weight <1500 g and a gestational age <32 weeks will be investigated at the neonatal outpatient clinic. Infants will be stratified according their feeding regimen (breast, formula and combined feeding) and their introduction of solid foods (early complementary feeding group: <17th week of life corrected for prematurity, late complementary feeding group: ≥17th week of life corrected for prematurity). Nutrient intakes and anthropometric parameters will be assessed at term, 6 weeks, 12 weeks, 6 months, 9 months and 12 months - all corrected for prematurity and with 40, 54 and 66 months.
The primary objective of this study is to determine whether baseline DOC screening can add to clinical and demographic data to predict the occurrence of a composite negative outcome (any of: recurrent stroke, myocardial infarction, death, or admission to a long-term care (LTC) / complex continuing care (CCC) facility) within one year of screening, in stroke prevention clinic patients.
The current model of care for the hospitalized elderly patients has been conditioned by many factors unrelated to the disease process that caused the hospitalization and usually worsen the outcome of hospitalization circumstances. Many times hospitalized elderly patients spend most of the time in bed (even higher than 83% of bed rest versus 4% of those who stand or are walking). These patients have their functional and physiological reserve reduced which makes them more vulnerable to the effects of being bedridden. The consequences are at multiple levels emphasizing the functional loss or cognitive impairment, longer stays, mortality and institutionalization, delirium, deconditioning, pressure ulcers and decreased caloric intake, social isolation, poor quality of life and increased use of resources related to health. Exercise training can prevent functional and cognitive decline and modify even the posterior trajectory.
Multiple sclerosis (MS) is a progressive neurological disease that affects over 2.5 million people worldwide. Up to 50% of persons with MS (PwMS) will experience some form of cognitive impairment as a result of the disease including disturbances in memory, attention, concentration, information processing, and executive functions such as problem solving, and self-monitoring. MS-related cognitive impairments negatively affect many aspects of functioning and independent participation in everyday life. Thus, PwMS who experience cognitive impairments face a wide array of recurring barriers that pose grave challenges to carrying out everyday activities while trying to maintain multiple life roles and as they age. Management of cognitive symptoms can be addressed through rehabilitation which has the potential to reduce disability, prevent complications of the disease, and enhance participation, independence, and quality of life. Considering the high frequency of cognitive impairments in MS and their significant, complex impact on functioning and independence, it is critical that cognitive interventions be an essential component of MS rehabilitation. The overarching goal of this study is to develop and test a self-management, group-based cognitive rehabilitation program designed specifically for PwMS.
This multi-center (6 sites: Helsinki, Kuopio, Oulu, Seinäjoki, Turku, Vantaa) intervention study aims to prevent cognitive impairment, dementia and disability in 60-77 year old persons at an increased dementia risk. The 2-year multi-domain life-style intervention includes nutritional guidance, exercise, cognitive training, increased social activity, and intensive monitoring and management of metabolic and vascular risk factors. The primary outcome is cognitive impairment measured by a sensitive Neuropsychological Test Battery (NTB), and Stroop and Trail Making tests to capture early cognitive impairment typical for both Alzheimer's disease and vascular dementia. We hypothesize that the multi-domain intervention will reduce cognitive impairment in the study group compared to the control group during the initial 2-year intervention period and reduce dementia incidence after the extended follow-up (until at least 300 participants have developed dementia).
ICU-acquired weakness represents a common and often devastating disease process which affects greater than 50% of critically ill patients. This pathogenesis of this acquired disease is multifactorial and results in variable severity, ranging from mild, transient to severe, permanent dysfunction of peripheral nerves in additional to muscle. In affected patients, weakness may persist for months to years after the acute phase of their illness, and has been implicated as a major contributor to decreased functional status and quality of life. Muscle ultrasound has been validated for assessment of muscle size as well as diagnosis of myopathic and neuropathic changes in patients with other known neuromuscular diseases. The use of muscle ultrasound or other imaging modalities for diagnosis or monitoring of ICU-acquired weakness has not been studied, although a single study using muscle ultrasound has shown significant change in muscle size in ICU patients receiving high dose corticosteroids and a prolonged course of paralytic agents. The investigators plan to use multiple modalities to examine skeletal muscle catabolism, function, and structure in patients during critical illness and recovery. The investigators will combine physical exam, hand grip dynamometry, electrophysiologic studies, serum biomarkers, muscle biopsies, and muscle ultrasound to assess a group of critically ill patients during their hospital stay. The investigators will obtain additional data, including neuropsychiatric assessments, severity of illness scores, administration of potentially harmful medications, and pertinent daily laboratory data. This study will last approximately 12 months.
The aim of the present study is threefold: investigating 1) specific cognitive impairments in patients with congestive heart failure, 2) whether cognitive impairments in patients with decompensated heart failure improve after medical recompensation and 3) whether cognitive functioning is related to the long-term prognosis (mortality, rehospitalisation) of those patients.
Our overall aim is to determine if the administration of guanfacine in combination with aripiprazole, olanzapine, quetiapine, and/or risperidone is significantly more effective than any of those medications alone in treating some of the cognitive impairment in schizophrenia.
