Filter by:This study is a prospective, single arm, non-randomized, interventional study to evaluate the safety and effectiveness of Omental transposition (OT) in subjects with early stage AD. Within-subjects (repeated-measures) design will be utilized to compare follow-up outcomes to baseline. The following assessments will be performed at baseline, then at 1, 3, 6, 12, and 24 months following surgery: - Montreal Cognitive Assessment (MoCA) - Alzheimer's Disease Assessment Scale-Cognition (ADAS-Cog) - General Practitioner Assessment of Cognition (GPCOG) - Eight-item Informant Interview to Differentiate Aging and Dementia (AD8) Subjects who have early stage AD confirmed by a neuropsychological test (MoCA) and who are healthy enough to undergo surgery. The experimental procedure to be performed is omental transposition (OT) surgery. It will be performed as a laparoscopic or open procedure for omental lengthening and an open procedure for brain access, with a general surgeon performing the omental lengthening/tunneling and a neurosurgeon performing brain access/brain biopsy/omental placement on brain. Up to twenty-five (25) subjects, with the first 5 subjects being part of a learning curve group and the next 20 subjects being part of the experimental group. The duration of each subject's participation will be approximately 25 months from screening through the 24 month follow-up visit.
The purpose of this study is to determine whether by measuring changes in the thickness of the retinal nerve fibre layer (the photosensitive layer at the back of the eye) you could predict if someone would develop Alzheimer's disease in the future. The measurement is made by OCT (ocular coherence tomography), a noninvasive and relatively inexpensive test that uses light waves to scan the back of the eye.
Alzheimer's disease (AD) and vascular dementia (VaD) are the most common forms of dementia. Yet, the cause of these diseases is still unknown. A potentially important initiating factor is a disrupted blood-brain barrier. This can initiate cerebral microangiopathy, which has frequently been associated with VaD. Nevertheless, also in most AD patients a substantial increase of vascular damage has been observed. The present study investigates the correlation between blood-brain-barrier breakdown and cognitive decline in AD and VaD. An innovative dynamic contrast-enhanced MRI scan that has recently been developed and tested at our institute, will be used to measure blood-brain barrier permeability. Objective: We will investigate the relationship between this permeability measure and (i) cognitive performance and (ii) the status of MRI visible cerebrovascular pathology (i.e. white matter hyperintensities, lacunar infarctions, microbleeds) in the most common forms of dementia.
The purpose of this study is to determine whether Zydena (Udenafil) has positive effect on cognitive function in patients with Alzheimer's disease. This study is a randomized, double blind, placebo-controlled multicenter study.
The main objective of the study is to evaluate the use of EEG in the management and follow-up of neuropsychiatric disorders. Secondary objectives are therefore better understanding of the pathological activations in neural network during neuropsychiatric disorders, their clinical evolution and response to therapies.
Tau pathology and tangles have been associated with cognitive dysfunction causing neurodegeneration. AD, the most abundant tauopathy is characterized by amyloid plaques and tau tangles. An abundance of tau inclusions, in the absence of amyloid deposits, defines Pick's disease (frontotemporal lobar degeneration), progressive supranuclear palsy (PSP), corticobasal degeneration (CBD) and other diseases including frontal atrophy associated with cognitive clinical dysfunction of frontal dysexecutive syndrome, progressive nonfluent aphasia and semantic dementia as recently reviewed (Gozes 2010). It is the investigators aim to follow other protein expression [as per recent publications (Marksteiner et al., 2011)] in blood and CSF samples from those tauopathies. Significance: Results should establish the possibility of using tau and other proteins as markers for early detection and disease progression in FTD, also in comparison to Alzheimer's disease (AD).
G72 gene is located on the common linkage locus in bipolar disorder and schizophrenia, and it encodes D-amino acid oxidase activator (DAOA). There are evidences that elucidated G72 and D-amino acid oxidase(DAO) together playing a critical role in the pathophysiology of schizophrenia. Recently, reports discovered missense mutations in the DAO (R199W DAO and R38H DAO) are associated with familial amyotrophic lateral sclerosis (FALS), and our preliminary data showed that the level of G72 autoantibody decreases in patients with ALS compared with normal control. Thus, we want to find out whether G72 plays a role in ALS and neurodegenerative diseases including Alzheimer disease and Parkinson's disease. First, we detect G72 protein and its autoantibody in sera of neurodegenerative diseases patients using ELISA and Western blotting, and the data are compared with normal control. We hypothesize the levels of G72 protein and its autoantibody in neurodegenerative diseases are less than those in normal control. Then, we extract genomic DNA of neurodegenerative diseases patients, and use polymerase chain reaction(PCR) to detect single nucleotide polymorphism (SNP) of G72. We aim to detect G72 missense SNP variants presented in ALS, AD and PD.
The objective of this study is to evaluate the efficacy and safety of STA-1 vs placebo as an add-on treatment to donepezil in patients with mild to moderate Alzheimer's Disease (AD).
The main purpose of this study is find out how safe a single dose of bryostatin 1 is in patients with Alzheimer's Disease (AD). This study is also being done 1) to determine how effective a single dose of bryostatin 1 is in the treatment of AD, 2) to find out what happens to bryostatin 1 once it enters the body by measuring the levels of bryostatin 1 in blood, and 3) to measure a substance in the blood (protein kinase C) that may help to better understand how bryostatin 1 works.
Dementing syndromes are, for the most part, incurable. People with dementia become highly dependent and frequently have to move from their homes into residential aged care facilities. Medications aimed at reducing the severity of a number of symptoms associated with the different types of dementia have had only modest success. Increasingly, people with dementia, their families and carers are turning to supplementary or alternative approaches to the management of their symptoms. There are many published reports describing the successful use of music therapy in reducing the severity of many symptoms of dementia. These include reports of improved memory, improved language skills, reduced anxiety and depression, reductions in agitation and disruptive behaviours and better social relationships with family, peers and carers. However, the quality of evidence they provide for the most part fails meet the standards of evidence required by health care providers. This clinical trial will examine the effects of a music therapy intervention. The study will recruit 180 patients in sub-acute hospital wards. Participants will be randomly placed in groups that receive either occupational therapy or music therapy. Before the therapy programs begin, we will use questionnaires to measure memory function, language ability, orientation and mood. We will also record brain activity from the surface of the scalp, blood pressure and pulse to examine physiological responses. The same measures will be repeated after the 3 weeks of therapy to determine whether there has been any improvement in the symptoms of the participants and whether the group that had music therapy showed greater improvement than the group that had occupational therapy. We will make a video recording during one therapy session to allow us to observe levels of engagement and to assess changes in facial expressions. This will provide information about the immediate effects of music on mood and social interaction. The information we collect about brain activity and blood pressure will help us to understand how music therapy might bring about changes in the symptoms of dementia. This understanding will be useful in developing better applications of music therapy. It will also add to our current knowledge about how the various diseases cause the problems they do. In summary, the primary aim of the project is to determine whether the reported effects of music therapy are supported by objective evidence.
