Active clinical trials for "Dementia"

The investigators' aim is to assess the effect of a model of preoperative as well as early postoperative care, treatment and rehabilitation in a dedicated orthogeriatric ward in a single-blind randomised study. The investigators' main hypothesis is that an orthogeriatric service may improve long-time cognitive outcome.

Investigations into the components of cognition damaged in frontotemporal dementia (FTD) demonstrate that patients with FTD show deficits in facial and verbal expression recognition, lack insight into what others think or might do (theory of mind skills), and in decision making tasks requiring processing of positive versus negative feedback. These cognitive functions are thought to be critical for appropriate social behavioural regulation (Blair, 2003). Recent studies in animal models and humans suggest that the neuropeptide oxytocin is an important mediator of social behavior and that oxytocin may facilitate emotion recognition, theory of mind processing, and prosocial behaviors (Donaldson and Young, 2008). Together, these findings suggest that upregulation of oxytocin dependent mechanisms of social and emotional cognition may be a valuable treatment approach in patients with FTD. The aim of this study is to determine how administration of intranasal oxytocin to patients with frontotemporal dementia affects behavior and processing of specific types of social and emotional information.The investigators' hypothesis is that oxytocin administration will improve emotional and social cognitive deficits in patients with FTD, resulting in improved decision making and behaviour.

This is an open-label study to investigate the effects of the rivastigmine patch on attention and behavior in Parkinson's disease when associated with memory and/or thinking problems. Rivastigmine (also sold under the name Exelon) is an FDA approved medication used for the treatment of mild to moderate Alzheimer's Disease (AD) and memory or thinking problems due to Parkinson's disease. Recently a rivastigmine patch was developed, which has shown similar effectiveness with fewer side effects and increased caregiver preference when compared to capsules. This is an open-label 12 week study where 15 subjects diagnosed with Parkinson's Disease who have mild to moderate memory and/or thinking complaints will be treated with the rivastigmine patch at UCSF. This study also analyzes the mechanism by which the rivastigmine patch works in people with Parkinson's disease and memory and/or thinking problems.

The core study assessed the efficacy of a higher dose of rivastigmine 13.3 mg/24 h transdermally (15 cm^2 patch) compared to a lower dose of the rivastigmine 4.6 mg/24 h transdermally (5 cm^2 patch) in patients with Severe Dementia of the Alzheimer's Type in a 24-week study. The extension study obtained additional safety and efficacy data, as well as provided the higher dose rivastigmine patch to all patients who completed the core study for an additional 24 weeks.

The purpose of this study is to determine if a home based occupational therapy is effective in the treatment of dementia.

The purpose of the study is to evaluate the safety and tolerability of acupuncture for patients with BPSD & healthy volunteers.

Frontotemporal lobar degeneration(FTLD) is a common cause of early-onset dementia. FTLD is characterized multiple behavioral symptoms including mental rigidity, irritability, emotional blunting, disinhibition, apathy, and aggression. These behavioural disturbances are particularly important because they increase caregiver burden and may lead to earlier institutionalization. While the causes of FTLD are largely unknown, there is a great deal of evidence suggesting that a brain chemical called serotonin regulates many of the behaviours that are disturbed in FTLD. Our objective is therefore to determine whether dysfunction in the brain's serotonin system is responsible for behavioural problems among FTLD patients. We hope to take the first steps towards a scientific understanding of the behavioural symptoms of FTD, and use our findings to support a larger study optimizing the treatment of targeted behavioural disturbances in FTLD using the antidepressant citalopram. Citalopram increases transmission by serotonin; we plan to use this medication to determine whether there are any differences in how the serotonin system functions in FTLD patients who display different levels of behavioural disturbances. Patients will be given citalopram and will have their blood drawn after 2 and 3 hours to determine plasma levels of the hormones cortisol and prolactin at those times. These hormones are good indicators of serotonergic functioning in the central nervous system. We expect that patients with lower levels of serotonergic functioning will have more severe behavioural disturbances and be less responsive to treatment with citalopram. Following their first test day, we will provide patients with a 6-week supply of citalopram, and assess them for any changes in behaviour at the end of this treatment. This study aims to obtain a better understanding of how changes in the serotonin system relate to behavioural symptoms in FTLD patients. Using the information from this pilot study, we can plan a larger study to determine whether certain behaviours will respond to treatment with citalopram, and if so, determine whether it is possible to predict which patients, based on individual characteristics, are most likely to respond to this treatment. This methodology will therefore not only provide a scientific rationale for treatment of FTLD, but also provide guidance for ongoing, individualized therapy.

The aim of this study is to discontinue antipsychotics and antidepressants, and to study its effect on Behavioural- and Psychological Symptoms in Dementia (BPSD).

The purpose of this study is to provide long-term safety data for rivastigmine capsule and transdermal patch treatments, in particular the effect of rivastigmine on worsening of the underlying motor symptoms of Parkinson's Disease (PD), in patients with mild to moderately severe dementia associated with PD.

Apathy in dementia prevents successful application of non-pharmacological treatments, accelerates cognitive and functional decline and increases disease-related costs by earlier need for full-time care. Apathy is a distinct entity and occurs independently of other neuropsychiatric syndromes, like depression. Today, there is no high-level evidence for any effective treatment of apathy in AD. In contrast to other neuropsychiatric syndromes in AD, like psychosis and depression, and despite its high prevalence and clinical relevance, apathy has never been the primary outcome in a clinical trial. Basic and clinical research has provided a distinct model of the pathophysiology of apathy with dopamine and norepinephrine as the key neurotransmitter systems involved. The antidepressant Bupropion is a dopamine and norepinephrine reuptake inhibitor. There is evidence from case-series, that Bupropion reduces apathy in patients with organic brain disorders. This study will test the efficacy and safety of Bupropion in the treatment of apathy in AD in a 12-week multicenter doubleblind placebo controlled trial. Secondary endpoints will be quality of life of patients, caregivers' distress, ability of patients to perform activities of daily living,utilization of healthcare resources by patients and by caregivers, and cognitive functions.
