Filter by:The purpose of this study is to explore the pathogenesis of cognitive impairment after acute cerebral infarction by applying the multimodal function MRI to dynamically observe the changes of the value of NAA,Cho,Cr,FA in a certain region in the brain and the function of the brain ,and to provide a visual instrument for evaluating the therapeutical effects of Chinese medicine through the application of multimodal function MRI to observe the changes of the neurotransmitter in certain area in the brain before and after the treatment.
Thyroid carcinoma is the common endocrine system malignant neoplasm. At present it has become the malignant neoplasm of fastest growing incidence rate. More than 90% thyroid carcinoma is thyroid differentiated carcinoma（DTC）. Postoperative oral L-thyroxine suppressing thyroid stimulating hormone (TSH) treatment is the standard therapy in DTC patients. While TSH-suppressive therapy with L-thyroxine can cause subclinical hyperthyroidism in treatment of patients with thyroid differentiated carcinoma. The impact of this therapy on cognitive functions and mood have not been systematically studied. The investigators infer the subclinical hyperthyroidism caused by TSH-suppressive therapy may impact cognitive function and mood disorders in DTC patients. The aim of this study is to explore the possible mechanism of cognitive function impairment in the course of TSH-suppressive therapy by rat model of total thyroidectomy + TSH-suppressive therapy and clinical trials. The result of this study may provide clinical and experimental basis for the side effects risk result form TSH-suppressive therapy in DTC patients.
Transcranial direct current stimulation has shown promising results in stroke patients. This study is a double blind, sham-controlled clinical trial aiming to compare the long-term effects of stimulation in two different cognitive regions after a stroke. Sixty patients who suffer from chronic strokes will be randomized into 1 of 3 groups: dorsolateral prefrontal cortex, cingulo-opercular network and motor primary cortex (control). Each group will receive transcranial direct current stimulation for 20 minutes for 10 consecutive working days (2 weeks). Patients will be assessed with a Dysexecutive Questionnaire, Semantic Fluency test, categorical verbal fluency and Go-no go tests, Wechsler Adult Intelligence Scale, Rey Auditory-Verbal Learning Test, Letter Comparison and Pattern Comparison Tasks at baseline, after their tenth stimulation session (week 2) and endpoint (week 4). Those who achieve clinical improvement with neurostimulation will be invited to receive treatment for 12 months as part of a follow-up study.
A prospective randomized controlled trial aimed at assessing if electroacupuncture (EA) combined with donepezil is more effective than donepezil for improving the cognitive function of AD patients. The hypothesis of this study is as follow: - Is the short-term effect of EA combined with donepezil better than donepezil on improving cognitive function of patients with Alzheimer's disease after 12 weeks' treatment? - Whether the effect of EA combined with donepezil on improving cognitive function can last until the end of 6 months' follow-up?
Postoperative cognitive dysfunction (POCD) may lead to serious consequences. But the underlying mechanisms are still unclear. Blood Oxygen Level Dependent (BOLD) fMRI and biochemical indicators will be used to explore the underlying mechanisms and represent a promising precursory target for diagnosis and treatment of POCD.
background: The Chronic Fatigue Syndrome (CFS) presents many disturbances multidimensional affect holistically to people who have the disease and current management of fatigue, pain, anxiety, depression and sleep disturbances present in this clinical entity is unsatisfactory. Hypothesis: The hypothesis of this essay is to contrast that acupuncture is more useful than placebo. The investigators suggest the use of a clinical study protocol (PEC), randomized, placebo-controlled, acupuncture technique, aimed at increasing the patient's sense of well-being, relief of pain and stiffness, acupuncture is effective to reduce fatigue, anxiety, depression and sleep disorders in patients diagnosed with CFS.
The investigators will evaluate the determinants of cerebral impairment in patients with non-ischemic heart failure compared to controls, and its relation to cognitive function. They hypothesize that patients with heart failure have impaired brain perfusion and hemodynamic factors are associated with cognitive dysfunction.
This study evaluates cognitive impairment in subjects with Parkinson disease (PD) and similar neurological disorder through obtaining longitudinal clinical and neuropsychological data. The long term goal is to have a well-characterized subject population to contribute to our understanding of the natural history, diagnosis and ultimate treatment of cognitive impairment in patients with PD and similar disorders.
The aim of this study is to observe how the hemodynamic changes induced by spinal blockade affect cerebral oxygenation. Elderly patients are very frail. Hypotension is very frequent during spinal anaesthesia. Bradycardia is other side effect of regional anaesthesia affecting cardiac output and cerebral blood flow. These complications of spinal anaesthesia could decline cognitive function. In this way a non invasive monitoring technique as cerebral oximetry is useful for the safety of anesthetic procedure.
The purpose of this study is to collect the prevalence of geriatric syndrome, which is recognized by an internist, and to compare the data based on the comprehensive geriatric assessment by a geriatrician. The secondary outcome is to develop a practical collected form for the internist.
