Filter by:So far, no drugs have shown to stop or delay the pathological processes of dementia. Available pharmacological treatment includes a small number of drugs; cholinesterase inhibitors like donepezil, galantamine and rivastigmine, and the NMDA receptor antagonist memantine, all of which only affect the symptoms of the disease. At the same time, alternative medicines like herbal products and dietary supplements are often intensively marketed with the assertion of curative or alleviating effects on dementia. The documentation of clinical effects, side effects and the potential for interaction with prescribed drugs are, however, generally scarce. The aims of this study are to make a survey of the use of alternative medicine in patients with dementia and mild cognitive dysfunction attending the investigators out-patient dementia clinic, and to assess the interaction potential with the patient's other medications.
The investigators would like to conduct a double blind placebo-controlled prospective study to show the impact of a treatment combining a specific cognitive rehabilitation program and acetylcholinesterase inhibitors on executive function of young patients 3 months after a first symptomatic stroke. The secondary objectives will be to assess cognitive changes performance (executive but also non trained functions such as memory) before and after treatments and treatment effect on activity of daily living and on quality of life. The main objective of this study is to show the impact of this combined treatment on brain activation maps in VCI-ND patients in the post-acute phase (3 months) after a stroke. Treatment effect will be assessed by functional MRI (fMRI) while patients will be performing a specific executive task. The investigators hypothesize that the specific rehabilitation associated with acetylcholinestrase inhibitors treatment will focalize cerebral activation observed in fMRI, improve executive functions specifically, improve non trained cognitive functions (generalization effect).
The aim of this randomized controlled study is to investigate if medication reviews performed by a clinical pharmacist as part of a ward team can reduce drug related problems and reduce readmissions to hospital among elderly patients (≥65 years) with dementia and cognitive failure. Four hundred and sixty patients will be recruited and randomized to control (usual care) and intervention group (enhanced service in which a pharmacist is part of the health care team). Six months after the last patient of the 460 has been discharged the study will be closed. Data about the number of readmissions and visits to the emergency room will be collected during the six-month follow-up and also, the costs associated with each visit or admission. Time until institutionalization will be compared between intervention group and control group.
The purpose of this study is to assess the relationship between cognitive impairment, patient self-management, health, and health service use in adults with heart failure (NYHA Class 2 and 3). The research questions are: 1. How is cognitive impairment (memory, attention, global and executive function) related to various aspects of impaired self-management (knowledge of adherence, adherence to sodium restriction and medications, symptom monitoring of weight changes, and decision and action to seek care)? 2. How are these relationships altered when adjusting for medical, demographic, and psychosocial factors? 3. What are the relationships among degree of cognitive impairment, quality self-management, health status, and health service use?
The primary purpose of this study is to determine whether sodium oligo-mannurarate capsule is effective and safe in the treatment of mild to moderate alzheimer' disease, and to determine the best therapeutic dose of sodium oligo-mannurarate capsule.
The initial phase of substance abuse treatment is a vulnerable period for relapse. Cognitive impairments are common during this phase and may reduce the ability to benefit from other forms of substance abuse and rehabilitation services. The study compares a rehabilitation program that combines work therapy with computer-based cognitive training of attention, memory and executive functions to work therapy alone in a 3 months outpatient substance abuse program. It is hypothesized that cognitive training will increase days of sobriety during the active intervention and better substance abuse outcomes at 6 month follow-up.
The purpose of this study is to provide evidence for the feasibility and initial effectiveness of a manualized, telephone-based (telehealth) approach to the delivery of cognitive interventions (SMARTease) targeted to improve cognitive performance in daily activities after stroke.
To date, there are no approved treatments for vascular cognitive impairment (VCI) and the main therapeutic efforts are aimed at controlling vascular risk factors for countering VCI development or progression. Several studies have reported cholinergic deficits in brain and cerebrospinal fluid of patients with VCI. The effect of choline alphoscerate in clinical studies of Alzheimer's disease and VCI improved memory and attention impairments. The purpose of our study is to determine effectiveness of choline alphoscerate vs placebo in improving cognition in post-stroke patients with VCI-non dementia (VCI-ND).
For many, Alzheimer's disease is the number one medical issue facing our aging society. It is a late onset neurodegenerative disease, frequently under diagnosed, that impairs memory and cognitive performance. There are no known treatments that can either prevent or reverse its progression. Consequently, there still remains a need to evaluate treatments which can better stabilize the symptoms of this disease. These symptoms frequently include decreased functional capacity and negative psychological attributes (e,g, depression, anxiety) in association with the memory and cognition deficits. This current study is being done to assess an investigational compound that has been designed to not only improved the cognitive status of affected patients but to also better manage all symptoms. Hence, the ultimate goal is to provide patients with an improved quality of life by slowing the progression of this neurodegenerative disease
In the cross sectional study "Adelahyde 1" which took place between 2001 and 2005, the investigators data suggest that vascular alterations may play a role in the setting of subjective memory complaints. This longitudinal study (Adelahyde 2) aims to confirm the role of vascular factors in the evolution of cognitive function and dementia.
