Active clinical trials for "Dementia"

Dementia is a chronic progressive mental disorder that adversely affects higher cortical functions, including cognition and behavior leading up to disability and dependence in daily life activities. It has become a major public health concern because of its increasing prevalence, chronicity, burden for caregivers, and the high personal and financial costs needed for care. Alzheimer disease (AD) is the most prevalent form of dementia, occurring in 5% to 7% of individuals older than 60. In Portugal, Santana et al study estimated that 160 287 people above 60 years had a diagnosis of dementia in 2013 (prevalence of 5,9%).The increasing national and international prevalence of dementia and its associated burden then imparts a high priority on delivering safe and effective treatment options. Currently approved treatments available for the symptomatic management of mild to moderate AD include cholinesterase inhibitors (ChEIs) (donepezil, rivastigmine, and galantamine) and a N-methyl- D-aspartate receptor antagonist (memantine). These drugs are also given off-label for other types of dementia (vascular and mixed dementias), with treatment continuing through advanced disease stages. Given that ChEIs have demonstrated short-term modest stabilization on measures of cognition and global functioning in randomized controlled trials (RCTs), several practice guidelines have proposed ChEIs for the treatment of all stages of AD, with some advocating ChEI discontinuation if tolerability issues arise, or if there is no longer a noticeable clinical benefit. Further studies in this setting are important as patients with severe dementia are more functionally impaired, present with comorbid illnesses, posing a higher risk of polypharmacy. In addition, ChEIs have a potential risk of adverse events including nausea, diarrhea, insomnia, vomiting, muscle cramping, fatigue, and weight loss. Less commonly, ChEI might be associated with rhabdomyolysis, convulsions, falls, syncope, pneumonia and death. Because cognitive and behavioral impairments change during the progressive disease course, the effects of medications may be unpredictable, especially over long durations of treatment. It might be challenging to weigh minimally beneficial effects against predicted harms of continued treatment, considering both patient and caregiver-centered care goals besides less clinically relevant cognitive outcomes. Only a small number of discontinuation RCTs were conducted to date but involved relatively few participants with heterogeneous designs, disease severities and outcomes. As so, clinicians take individualized discontinuation decisions and the only consensual domains are a lack of response and a loss of effectiveness. The present pragmatic clinical trial will compare the efficacy of maintaining pharmacological treatment versus treatment cessation on cognition, behavior, functional disability and quality of life of patients and caregivers, among patients with severe dementia due to AD, with or without small vessel subcortical vascular disease. The investigators will consider other important endpoints besides cognitive functioning including mood, apathy, energy and neuropsychiatric symptoms. Moreover, this trial will try to look for outcomes that engage patients and families in treatment decisions.

The main objective of the study is to evaluate the efficacy of a combined training program of physical exercise and multisensory stimulation (Physiocognitive Integration) in people with mild/moderate cognitive impairment.

A study to determine the safety and efficacy of BXCL501 dosing for episodes of agitation associated with dementia when they occur (given as needed [PRN]), for a maximum of 28 doses within a 12-week treatment period.

The goal of this intervention study is to test whether the educational intervention work well or not on informal caregiver of person with dementia. The main question it aims to answer is does the educational intervention will help to reduce the caregiver burden experience by the informal caregiver. Participants will be given an educational module and short videos that they can refer to gain more knowledge and skills in caring for the person with dementia.

The purpose of this randomized controlled pilot study is to examine the preliminary effectiveness, feasibility, and potential treatment moderators (i.e., behavioral symptoms and spousal relationship status) of a newly developed intervention for individuals with dementia and their family caregivers that combines elements of the established care consultation (CC) approach with additional counseling modules (CC+C). Outcomes for Veterans with dementia and their family caregivers (e.g., depressive symptoms, care-related burden, quality of life, pleasant events, etc.) will be assessed after 6 months of treatment and again at 12 months.

Evaluation of the safety and tolerability of a 20 mg once daily dose of memantine compared with 10 mg given twice daily in patients with dementia of Alzheimer's type and MMSE range 5-18.

Apathy in Dementia Methylphenidate Trial 2 (ADMET 2) is a Phase III, placebo-controlled, masked, 6 month, multi-center randomized clinical trial sponsored by National Institutes of Aging involving 200 participants with Alzheimer's disease (AD). ADMET 2 is designed to examine the efficacy and safety of methylphenidate as treatment for clinically significant apathy in AD participants. ADMET 2 will enroll participants from real world settings such as outpatient, nursing home, and assisted living facilities and will examine the effects of methylphenidate on apathy and cognition. ADMET 2 will also conduct careful safety monitoring.

The purpose of this study is to determine if a home based physical activity training program for patients with Alzheimer's dementia has effects on clinical and neurobiological parameters.

The objective of this trial was to assess the dose-response relationship of symptomatic efficacy of talsaclidine base on ADAScog and to assess safety and tolerability

This trial aims to collect pilot data to explore whether bilateral deep brain stimulation (DBS) of the Nucleus Basalis of Meynert (NBM) has beneficial effects on memory and thinking impairments among individuals with Dementia with Lewy Bodies (DLB).
