Filter by:The diagnosis of Alzheimer's disease (AD) is based on clinical and neuropathological criteria. Some patients have a contributive CSF biology to determinate a high level risk of AD (Tau + phospho-tau ratio increased and Ab42 / decreased Aβ40), but others have an intermediate CSF biology (Tau and/or phospho-tau increased but Ab42 ratio / normal Aβ40) and are unclassifiable. 18F-Florbetaben (Neuraceq®), a radioisotope in positron emission tomography (PET), selectively binds to amyloid plaques, with high detection sensitivity (98%). Detection of amyloid plaques by PET imaging separate patients according to the criteria of Dubois, as with AD and allow them to benefit a cholinesterase inhibitor treatment. If negative, the diagnosis of AD can be excluded with a high level of confidence to prevent initiating unnecessary treatment, expensive for the community. This is the first imaging study of amyloid plaques targeting population whose diagnosis of AD is uncertain according to the CSF biology. The aim of this study is to describe the results of amyloid PET in case of intermediate CSF biology and to separate patients as AD or not according to the criteria of Dubois
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.
The purpose of this Phase IIa study is to determine whether the AD Immunotherapeutic Vaccine (UB-311), targeting the amyloid beta peptide (N-terminal amino acids, 1-14), is safe and immunogenic in mild AD patients. In addition, the efficacy profiles will be evaluated as the secondary endpoint.
This study evaluates the side effects of dose escalation in the treatment of donepezil 23mg for patients with Alzheimer's disease. Investigators randomly divide participants into three groups according to the dose escalation method; no titration, 15mg of donepezil for a month before escalation to 23mg, and alternating of 10mg and 23mg for a month before escalation to 23mg.
This is a Phase II, ascending dose study of CPC-201 in patients with dementia of Alzheimer's type to determine the optimal dose titration schedule.
This is a global Phase III, randomized, double-blinded, placebo-controlled study for subjects with evidence of early AD. The protocol is designed to determine whether ALZT-OP1 combination treatment (ALZT-OP1a + ALZT-OP1b) will slow down, arrests, or reverse cognitive and functional decline, in subjects with evidence of early stage Alzheimer's disease (AD).
To determine if treatment with HTL0009936 will lead to changes in neural activity, measured using the fMRI BOLD signal and ASL, in brain areas that are associated with spatial and working memory, learning and executive functioning.
This study involves the use of an investigational drug called NGP 555. In each group of healthy subjects, 2 people will receive placebo and 6 people will receive NGP 555.
This study evaluates the effect of applying low level laser light therapy to individuals with mild to moderate Alzheimer's disease to see if it may improve their memory, thinking and behaviors. Half of the participants will receive the real treatment with the laser device and the other half of the participants will receive a placebo treatment (not active laser).
In this study the investigators aim at assessing and then enhancing neuroplasticity in the dorsolateral prefrontal cortex (DLPFC) and working memory - a key function of DLPFC - in patients with mild Alzheimer's disease (AD). The investigators will use Paired Associative Stimulation (PAS) paradigm to measure neuroplasticity and then a 4-week course of high-frequency repetitive Transcranial Magnetic Stimulation (rTMS) to the DLPFC to enhance cognitive function. Clinical and cognitive assessments will be done at baseline, one week, one month and 6 months after the rTMS course. Healthy controls will also be enrolled to carry out baseline cognitive assessments and a baseline measurement of neuroplasticity.
