The primary objective of this study is to conduct a randomized, controlled trial to determine whether engaging in mental activity or exercise, either alone or in combination, improves cognitive function in non-demented, inactive older adults who self-report a recent decline in memory or thinking. In addition, we, the researchers at the University of California, San Francisco, plan to seek funding to follow subjects over time to determine whether these interventions are associated with changes in rate of cognitive decline or risk of dementia after the intervention period has ended.
Geriatric patients have a high risk of developing postoperative cognitive deficits. Hypothetical causes are insufficient intraoperative cerebral perfusion or drugs that are administered in the perioperative setting. This study will investigate the role of these two factors in patients aged 65 or older undergoing elective surgical procedures under general aesthesia. Non-invasive techniques will be used to monitor intraoperative cerebral perfusion and anticholinergic activity in the patient's blood is determined. Data will be compared to those of a young (20-40 year old) group of patients undergoing elective surgical procedures using an identical anesthetic technique. A second control group of healthy volunteers older than 65 will be investigated to quantify practice effects with repeated testing of cognitive functions.
This study proposes a prospective randomized study of elders undergoing elective major abdominal surgery to assess recovery following a unique anesthetic regimen incorporating a adrenergic receptor antagonist. The purposes of this study are to: 1. to determine if using atenolol, a beta-blocker drug commonly used to treat high blood pressure and heart disease, as part of your anesthetic regimen will decrease complications that sometimes occur in elderly patients who are undergoing surgery and being given anesthesia. 2. to see if it improves or quickens your recovery from anesthesia and surgery. 3. to help investigators design better ways to administer anesthesia during surgery, especially in elderly patients, so that the complications and the time to recover from surgery and anesthesia can be decreased.
Cognitive and emotional symptoms are often seen in the acute phase of a stroke. The prevalence of such symptoms later and the mechanisms explaining the symptoms are not fully known. The causes of poststroke dementia are likely to be multifactorial (Cerebrovascular Diseases 2006). The investigators want to include all patients with first ever stroke without significant cognitive decline prior to the stroke (IQCODE cut-off 3,7) and follow them up for one year. At baseline we will make stroke classifications, measure neurological deficits according to NIHSS, evaluate cognitive and emotional function and make registrations of vascular risk factors, including precerebral color duplex scan with measurement of IMT in CCA. The investigators will then randomize the patients into multifactorial vascular-risk-factor-intervention in the hospital or care as usual in the primary health care. 8-12 months after stroke onset, survivors will undergo new examinations to evaluate neurological, cognitive and emotional functions, as well as MRI and SPECT.
The purpose of this study is to determine the safety and effectiveness of an investigational drug MK0249 for the treatment of the cognitive impairment in patients with schizophrenia.
Cognitive dysfunction following chemotherapy is an adverse treatment effect that impacts the quality of life for many cancer survivors receiving this adjuvant therapy. A strong body of evidence now indicates that that the initiation of a regular exercise program, at levels that are readily achievable by most adults (3-5 d/wk, 30-45 min/session), can improve cognitive function. Importantly, the domains of cognitive function that are enhanced by exercise participation are the same domains that are negatively affected by chemotherapy. Accordingly, we propose a 2 year research program that seeks to develop and test a safe, simple, and effective exercise intervention to optimize cognitive function following chemotherapy. To begin this research, we will: 1) conduct a randomized exercise intervention trial among cancer survivors that report persistent cognitive problems following chemotherapy (n=60), 2) explore possible mediators and moderators of the intervention on cognition in order to begin to understand how the intervention may work and for whom it may be most effective, and 3), conduct a cross-sectional study comparing cancer survivors enrolled in the trial (n=60) and matched controls (n=40) to evaluate the cognitive status among survivors in the intervention. We hypothesize that six-months of regular exercise will enhance cognitive function among cancer survivors, and that cancer survivors reporting cognitive dysfunction will have lower objectively measured cognitive performance than adults who have not received chemotherapy. To our knowledge this study would be the first to examine the influence of regular exercise participation on cognitive function among cancer survivors that experienced cognitive difficulties following chemotherapy.
This research involves assessment of cognitive outcome in childhood cancer as well as evaluation of a cognitive rehabilitation program for improving learning and problem solving difficulties in children with cancer.
The primary objective of this study is to evaluate if adjunctive armodafinil treatment can improve the cognitive deficits in patients with schizophrenia
The purpose of this study is to determine the safety and effectiveness of an investigational drug for the treatment of cognitive impairment in patients with schizophrenia.
