Active clinical trials for "Dementia"

The purpose of this study is to evaluate the safety and effectiveness of galantamine (a drug for treating dementia) versus placebo in the treatment of patients with Alzheimer's disease using a flexible dose design.

The purpose of this study is to determine the safety and efficacy of escitalopram (Lexapro) using 10 or 20 mg daily in patients with Alzheimer's disease who are also experiencing agitation.

The purpose of this study is to assess the effectiveness and safety of galantamine hydrobromide treatment in patients with severe Alzheimer's disease.

This study will determine the effectiveness of combining escitalopram, venlafaxine, or duloxetine with donepezil, a medication used in Alzheimer's disease, in improving memory, concentration, attention, and problem solving abilities, and reducing the risk of depressive relapse in older individuals with depression.

one year extension study following a previous double-blind study to evaluate safety of the drug

The purpose of this study is to determine whether an antipsychotic medication alone or an antipsychotic medication in combination with divalproex is the most effective and safest way to treat agitation in elderly patients with dementia.

This study will employ a double-blind, placebo-controlled approach to assess the effect of 1072nm infrared (IR) phototherapy on the behavioral and cognitive symptoms associated with early and mid-stage dementia.

This study will test the effects of a medication called tolcapone on cognitive, behavioral, and language problems seen in patients with frontotemporal dementia (FTD). Tolcapone increases the amount of dopamine, a brain chemical that may be lowered in FTD. The study will see if tolcapone can improve thinking, behavior, and language in people with FTD and will look at the effects of the drug on brain activity. Patients with FTD who are between 40 and 85 years of age may be eligible for this study. Participants will be seen as outpatients at the Columbia University Medical Center approximately one a week for 4 weeks. They take tolcapone or a placebo (a look-alike pill with no active ingredient) during study week 1. During study week 3, those who took placebo during week 1 now take tolcapone for 1 week and those who took tolcapone now take placebo. In addition, patients undergo the following tests and procedures: Neurological tests to evaluate attention, problem-solving and memory. These tests are repeated several times during the course of the study. Test to look for a gene that affects the amount of dopamine in the brain, using blood samples collected in a previous study. Blood draws four times during the study. Functional MRI (fMRI) to learn about changes in brain regions that are involved in performing tasks. For fMRI, the patient lies on a table that can slide in and out of the scanner, a narrow metal cylinder surrounded by a magnetic field. The procedure takes about 60 minutes and is performed four times over the course of the . FMRI involves taking pictures of the brain during MRI while the subject performs a task so that changes in the brain that occur during these tasks can be studied.

To determine the connection between Social Withdrawal and Sensory Deprivation in elderly clients with Alzheimer's Type Dementia (i.e. how providing sensory stimulation might reduce social withdrawal).

The primary objective of the study is to obtain preliminary safety and tolerability data with davunetide (NAP, AL-108) in patients with a tauopathy (frontotemporal lobar degeneration [FTLD] with predicted tau pathology, corticobasal degeneration syndrome [CBS] or progressive supranuclear palsy [PSP]). The secondary objectives of this study are to obtain preliminary data on short term changes (at 12 weeks) in a variety of clinical, functional and biomarker measurements from baseline, including cerebrospinal fluid (CSF) tau levels, eye movements, and brain MRI measurements.
