Filter by:A randomized controlled trial designed to test the effectiveness of a psychological intervention based on group therapy for the caregivers of Alzheimer's disease patients. The intervention consists of 14 sessions of a cognitive-behavioral psychological group therapy. This study aims to demonstrate that Alzheimer's patients' caregivers can benefit from group counseling, with an improvement in mood state, quality of life, perceived burden and a decrease in anxiety and depression. Two evaluations will be done: before the therapy sessions (basal) and when intervention is finished (final).
The current study is planed to compare the efficacy of real (anodal and cathodal) vs sham transcranial direct current stimulation (tDCS) applied over the left dorsolateral prefrontal cortex (DLPFC) on cognitive functions and cortical excitability of patients with Alzheimer disease (AD). Thirty three with mild to moderate Alzheimer's disease (AD) patients (diagnosis of probable AD according to the criteria of the National Institute of Neurological and Communicative Disorders and Stroke Alzheimer Disease and Related Disorders Association [NINCDS-ADRDA] were included in this study) were randomly classified into one of three groups (eleven for each group). The first group received anodal tDCS over left DLPFC and 2rd group received cathodal tDCS on the left DLPFC and the 3rd group received sham tDCS stimulation, daily for 10 consecutive days (5 days/week for 2 weeks). Minimental State Examination (MMSE), psychometric assessment for cognitive functions (MMSE, Wechsler memory scale, Wechsler adult Intelligent scale) were assessed before, after 10th sessions, and then after 1 and 2 month. Cortical excitability was assessed in both hemispheres before and after the end of sessions. Neurophysiological evaluations included resting and active motor threshold (rMT and aMT), and cortical silent period (CSP). At the time of recruitment, none of the patients taking antidepressants, or neuroleptic, sedative-hypnotic drugs for at least two weeks before the assessment. All participants or their caregivers will give informed consent before participation in the test and after full explanation of the study protocol. Outcome: The real group received (anodal and cathodal) tDCS are expected to have more improvement on cognitive functions compared to sham tDCS group. tDCS is considered new adjuvant non pharmacological therapeutic tool for management of AD patients with mild to moderate degree dementia.
In a retrospective analysis of data from 1100 patients, disease-delaying effects of Cerefolin®/CerefolinNAC® were examined in terms of cognition. The purpose of the current study is to expand the retrospective study dataset by prospectively collecting additional biomarker and imaging data.
The insanities, priority of public health in 2008, have significant prevalency in Limousin, region in the ageing demography (1/3 of the population is more than 60 years old against 1/5th of average in France). To prevent the lack of therapeutic solutions, for these evolutionary diseases, the new plan Alzheimer 2008-2012 encourages the research. The insanities deprive gradually the individual of their autonomy, their personality and their identity. The help of an institution is sometimes inevitable. In the middle of this stressful environment, the patient affected by severe insanity, need marks. The aspect of their old objects, significant for them, has to be prioritized because the institutional universe, often depersonalized doesn't mean anything for them. In front of repeated failures, they're hurt in their self respect. The prevention of the undernutrition, comes by a preservation of praxis and pleasure at table. The institutional plate used in certain hospital sectors, is unpersonal (rectangular, divided) and can be destabilizing for the mentally ill person.
This study will evaluate the effects of daily dosing of AC-1204 on cognition, activities of daily living, resource utilization, quality of life, pharmacokinetic measures and safety among participants with mild to moderate Alzheimer's Disease.
The primary purpose of this study is to determine whether ELND005 is effective in treating symptoms of agitation and aggression in patients with Alzheimer's disease
The purpose of this study is to demonstrate that the change of attention measure is correlated with the changes of caregiver's burden after treatment with galantamine.
To establish a cutoff value using a ratio of CSF tau to Aβ42 (tau/Aβ42) for distinguishing patients wth mild to moderate Alzheimer's disease (AD) from health elderly control subjects. The investigators hypothesize that a cutoff can be found that has at least 80% sensitivity and 60% specificity.
The purpose of this study is to evaluate the safety of administration and effects of valproic acid on clusterin expression in cognitively-intact, healthy, elderly subjects. Clusterin mutations have recently been identified as a risk factor for the development of Alzheimer's Disease and changes in clusterin expression are seen in the elderly who develop Alzheimer's disease irrespective of whether they carry these genetic mutations or not. Valproic acid may prevent or reverse these changes. Fourteen subjects with normal memory and thinking will participate in this study. Ten of these subjects will receive valproic acid and 4 will receive a "placebo" capsule with no active medicine. Participants will take study medication or placebo for 28 days and be followed for a total 35 days in this trial.
The purpose of this study is to determine the value of Arterial Spin Labeling (ASL) MRI, a measure of blood flow to the brain, in Mild Cognitive Impairment (MCI) and compare it to existing measures. In particular, the investigators will compare ASL MRI to Positron Emission Tomography (PET/CT), which measures brain metabolism reflecting how well cells in a patient's brain are functioning. In addition, the investigators will assess the relationship of these measures to specific protein levels associated with Alzheimer's Disease in the patient's cerebrospinal fluid (the fluid that surrounds the brain and spinal cord) obtained by lumbar puncture. By comparing the information that is available from these procedures to the patient's performance on cognitive tests, the investigators hope to learn which procedures most accurately reflect and assist in determination of the potential causes of cognitive difficulties that arise with MCI, and thus, which are most useful in the clinical setting. In particular, PET scans have been found to be very useful in diagnosis of MCI and Alzheimer's Disease, but the investigators want to find out if they can get the same, or better, information from an ASL MRI scan, which is less expensive and easier to acquire.
