Active clinical trials for "Dementia"

The goal of this research study is to evaluate, in the open-label extension phase, the effectiveness, tolerability and safety of rivastigmine capsules in males and females between the ages of 50 and 85 years old with probable vascular dementia.

The purpose of the study is to evaluate the change in cognitive ability and activities of daily living in patients with Alzheimer's disease (AD) as measured by specific evaluations during 18 months of dosing.

Donepezil hydrochloride (Aricept) has been approved to treat symptoms associated with mild to moderate Alzheimer's disease (AD). Aricept has been shown to improve the memory and thinking abilities, activities of daily living and global function in patients. The purpose of the study is to further investigate the effectiveness and safety of donepezil in patients with severe Alzheimer's disease. Donepezil is thought to work in the brain by increasing the levels of an important brain chemical called acetylcholine. This chemical helps a person's memory to work better.

The purpose of this study is to evaluate the safety, tolerability, and efficacy of two dose levels of rasagiline mesylate versus placebo in patients with mild-to-moderate Alzheimer's Disease who are taking Aricept.

The purpose of this trial is to test the safety & tolerability of intramuscular aripiprazole in acutely agitated patients diagnosed with Dementia.

This study will compare the safety and effectiveness two medications, citalopram (Celexa®) and risperidone (Risperdal®).

The purpose of this study was to develop and examine the initial impact of a distance-based intervention for female family dementia caregivers. As stated in the original proposal, the primary hypothesis of the study was that family caregivers who participated in the Video Intervention would show greater reduction in psychological distress (i.e., on measures of depression and emotional distress following problematic patient behaviors) compared to those in the Basic Education condition, and that this effect would be maintained over time (3 and 6 months post-tx).

The primary aim of this study is to determine the safety and efficacy of quetiapine (Seroquel) for the treatment of psychosis and/or agitation in patients with primary dementia complicated by coexistent parkinsonism, or patients with Parkinson's disease with dementia [PDD] who have episodes of agitation or psychosis. The secondary aim is to determine the safety and tolerability, particularly the influence on parkinsonism, of quetiapine when used to treat psychosis and/or agitation in patients with dementia complicated by coexistent parkinsonism.

To test whether zidovudine (AZT) is useful as a treatment for the neurologic syndrome called AIDS dementia complex. To determine how long AZT takes to reach cerebral spinal fluid (CSF), how long, and at what concentration it is found there. HIV infection can result in impairment in the function of the brain and spinal cord, leading to disturbances in the ability to think clearly and in strength and coordination. This disorder, which has been called the AIDS dementia complex, may be due to a direct effect of HIV on the nervous system. It is known that AZT does get into the brain to some extent, where it may reduce growth of HIV. It is hoped that AZT will stabilize or improve the symptoms of the AIDS dementia complex.

The purpose of this study is to see if it is safe and effective to give thioctic acid and deprenyl (selegiline hydrochloride), alone or in combination, to HIV-infected patients who have mild to moderate dementia (a decline in their mental abilities).
