Antipsychotic Discontinuation in Alzheimer's Disease
Alzheimer DiseasePsychotic Disorders2 moreIn patients with Alzheimer's disease (AD) who respond to antipsychotic treatment of psychosis and/or agitation/aggression, the relapse risk after discontinuation is not established. AD patients with psychosis and/or agitation/aggression receive 16 weeks of open risperidone treatment (Phase A). Responders are then randomized, double-blind, to one of three arms in Phase B: (1) continuation risperidone for 32 weeks, (2) risperidone for 16 weeks followed by placebo for 16 weeks, (3) placebo for 32 weeks. The primary outcome is time to relapse of psychosis/agitation.

Methylphenidate for Apathy in Alzheimer's Dementia: A Controlled Study
Alzheimer's DiseaseApathy1 moreThe purpose of the study is to determine the efficacy of methylphenidate over placebo in treating apathy in patients with Alzheimer's dementia. Apathy is one of the earliest and most profound disturbances that occur in Alzheimer's dementia (AD). Hypotheses: 1. Methylphenidate (MPH) will improve apathy significantly more than placebo in AD. 2. Successful treatment of apathy will improve Instrumental Activities of Daily Living (IADLs), and caregiver burden.

Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of SAM-315 in...
Alzheimer DiseaseTo assess the safety and tolerability of ascending single oral doses of SAM-315, an investigational drug, in healthy Japanese male subjects.To obtain preliminary pharmacokinetic (PK) and pharmacodynamic (PD) profiles of SAM-315 in healthy Japanese male subjects.

Effect of Testosterone Therapy in Men With Alzheimer's Disease and Low Testosterone
Alzheimer's DiseaseHypogonadismTreatment with testosterone can improve performance on tests of spatial ability in men with low testosterone levels and Alzheimer's disease. Improved performance on these tests may mean an improved ability to get around in one's environment without getting lost or injured. This could have a positive impact on both patients and those who care for them. We will investigate what areas of the brain are involved in these improvements in spatial ability. This will be done using a PET scan, which creates a 3-dimensional image of the brain that can allow us to see how the brain functions.

Study of Memantine in Assessment of Selected Measures of Volumetric Magnetic Resonance Imaging (MRI)...
Alzheimer's DiseaseThe purpose of this study is to characterize the progression of disease using volumetric MRI techniques and cognitive outcome measures in patients with moderate dementia of the Alzheimer's type treated with open-label memantine.

Study Evaluating SRA-333 in Mild to Moderate Alzheimer's Disease (AD)
Alzheimer's DiseaseTo determine the safety and tolerability of multiple ascending fixed oral doses of SRA-333 in subjects with mild to moderate Alzheimer's disease.

Gene Therapy for Alzheimer's Disease Clinical Trial
Alzheimer DiseaseThis Phase I clinical trial is the first step in testing gene therapy. This study is called a "Safety/Toxicity" study by the Food and Drug Administration, and primarily aims to determine whether the experimental protocol is safe for humans. It will determine whether the study procedure causes side effects in humans, and may also give us a preliminary sense of whether this will be effective in combating Alzheimer's disease in humans.

Effectiveness of A Nutritional Brain Metabolic Enhancer for Alzheimer Disease
Alzheimer DiseaseThe purpose of this study is to evaluate the effectiveness of a nutritional supplement that has been developed to improve the brain function of a patient with Alzheimer's disease.

Treatment of Behavioral Symptoms in Alzheimer's Disease
Alzheimer's DiseasePsychosis1 moreThe optimal strategy for the treatment of behavioral complications in patients with probable Alzheimer's disease (AD) remains unclear. The objective of this study is to evaluate the risk of relapse following discontinuation of haloperidol in patients with Alzheimer's disease (AD) with psychosis or agitation who respond to it. In Phase A of this study, AD outpatients with behavioral complications receive 20 weeks of open haloperidol treatment with an oral dose of 1-5 mg daily, titrated individually to achieve the optimal trade-off between efficacy and side effects. Responders to Phase A participate in Phase B, a 24-week continuation trial in which patients are randomized to continuation haloperidol or placebo. The primary outcome is the time to relapse of psychosis or behavioral disturbance.

Pain Management and Behavioral Outcomes in Patients With Dementia
DementiaAlzheimer Disease3 moreDementia illness often co-exists with painful medical conditions associated with aging (e.g., degenerative joint disease, osteoarthritis, skin ulcers, back pain, headaches, cancer, or angina). While the standard practice is pain assessment for all patients, the elderly with dementia have special needs for assessment, management, and evaluation. When they are unable to verbalize pain, objective measurement of their discomfort are possible manifestations of pain. No research relates systemic pain treatment with reduction of negative problematic behaviors in patient dementia.
