Capturing the earliest stages of Dementia especially Alzheimer's Disease (AD) is a great challenge. Until now the NINCDS-ADRDA and the DSM criteria for AD were largely used as diagnostic standards in research. However, the research on AD progresses and some biomarkers have been recently suggested to improve the diagnostic criteria of AD, such as cerebrospinal fluid markers, neuroimaging with Positon Emission Tomography (PET) or Magnetic Resonance Imaging (MRI).
This clinical trial was performed to assess the clinical efficacy and safety of two 4 week treatment courses of daily intravenous administration of Cerebrolysin (20mL [milliliter] IV [intravenous] per day). The study was performed as prospective, randomised, double-blind, placebo-controlled, parallel group, multicentre study with 2 study groups. Group 1: 20 mL Cerebrolysin and 100 mg (milligram) acetylsalicylic acid Group 2: Placebo (0.9% NaCl [sodium chloride]) and 100 mg acetylsalicylic acid The study drug was given once daily by intravenous infusion (20ml in 250ml saline solution) for 4 weeks on five consecutive days per week. This treatment regimen was repeated after a two-month treatment-free interval. Acetylsalicylic acid was given orally, once daily throughout the study duration of 24 weeks. Altogether five clinical evaluation visits at Baseline (day 0) and at week 4, 12, 16, and 24 were necessary.
The proposed study is designed to evaluate the performance of the COGNISION™ System as a tool to assist physicians in diagnosing Alzheimer's Disease (AD) in real-world clinical settings. The design of this study is guided by two overriding factors: 1) to optimize the performance of the event related potentials (ERP) classifiers, the subjects making up the training sets must be well characterized as to their clinical diagnosis, and 2) all ERP tests must be performed and reproduced in real-world clinical settings.
The general aim of this research project is to determine the relationships between alterations of central cholinergic (ACh) and dopaminergic (DA) systems and neurobehavioral features of dementias with Lewy bodies (DLB). Both clinical and neurochemical data support the view that DLB is not a homogeneous entity and it can be hypothesized that differential alterations of central ACh systems (i.e. anterior vs posterior vs striatal interneurons) in association or not with a DA nigrostriatal dysfunction could partly support the clinical heterogeneity observed in this disease. ACh in vivo imaging has been relatively underutilized to date and to our knowledge only on the postsynaptic side. Furthermore, ACh/DA interactions and their relationships with the symptomatology of DLB and related pathologies (PDD) had never been investigated.
Therapeutic management of gait disorders in very advanced Parkinson's disease (PD) patients can sometimes be disappointing, since dopaminergic drug treatments and subthalamic nucleus (STN) stimulation are more effective for limb-related Parkinsonian signs than for gait disorders. Gait disorders could be also partly related to noradrenergic system impairment, pharmacological modulation of both dopamine and noradrenaline pathways could potentially improve the symptomatology. The investigators have demonstrated using an open label study on 17 advanced PD patients that chronic, high doses of methylphenidate (MPD) improved gait, freezing of gait, motor symptoms and attention in the absence of L-Dopa and increased the intensity of response of these symptoms to L-Dopa (Devos et al., 2007). The investigators aimed to confirm their results using a randomized, double-blind, placebo-controlled, parallel-group, multicentric trial. The investigators will assess the clinical value of chronic, high doses (1 mg/kg/day) of MPD vs placebo in 88 non demented PD patients suffering from severe gait disorders with freezing despite their use of optimal dopaminergic doses and eventually STN stimulation parameters. Efficacy will be assessed directly and on video in the absence of L-Dopa and again after acute administration of the drug, both before and after a 3-month course of MPD, using Stand Walk Sit test (primary criteria), the "Freezing Of Gait trajectory", RGSE scale, the UPDRS scores, the dyskinesia rating scale, Achiron scales and using auto-questionnaires of Giladi, ABC scale and PDQ 39. Attention will be assessed using reactions times. Drowsiness will be assessed using Epworth and Parkinson's disease Sleep Scales. Apathy and depression will be monitored with Lille Apathy Rating Scale, MADRS, BPRS, MINI and psychiatric interview. Cardiologic and general tolerance will be also monitored. This study could lead to propose methylphenidate with a good efficacy/ risk balance in advanced PD patients suffering from severe gait disorders with freezing of gait, drowsiness and attention deficit.
This study is collecting tissue specimens (blood, urine and saliva) from up to 1000 patients, with and without cognitive disorders, to store in the Bio Bank for future research. The specimens could be used in future research projects that could help improve the accuracy of diagnosis of a disease, predict who might develop a disease, help monitor the disease, or improve the understanding of the disease. Patients are only being recruited from Beaumont Hospitals Geriatric Clinic.
The purpose of this study is to pilot the home Environmental Skill-Building Program (ESP) and an educational control intervention with persons with dementia and their caregivers (n=40) in preparation for a larger double-blind randomized controlled trial. Caregivers of persons with dementia often deal with difficult behaviors. The ESP is an occupational therapy intervention that helps caregivers adapt to their environment and build care-giving skills. The areas addressed include changes to the home set-up, adaptive equipment, instruction in strategies of problem-solving, energy conservation, safe task performance, and fall recovery techniques. A trial is needed with methodological rigor and to determine if the intervention is feasible in the Canadian health care system. Results will contribute to understanding how caregivers and people with dementia can be supported in their home environments.
The Aricept® Evess study is a prospective, non-comparative, non-interventional study on use of Aricept® Evess in the treatment of out-patients with AD and Vascular Dementia. The 24 week length of the study aims to collect data from a large number of patients (n= 400) on the safety and efficacy at the usual dosage of the product providing an overview of Aricept® Evess profile.
The purpose of the study is to determine whether individualized social activities, physical resistance training and walking, and a combination of both are effective in improving nighttime sleep in elders with dementia.
