Chronic Electrical Stimulation of Hypothalamus/Fornix in Alzheimer's Disease
Alzheimer's DiseaseAlzheimer's Disease (AD) is the most common cause of dementia for which no treatment has shown consistent efficacy to stop or slow down the disease. Recent report of enhancement of memory abilities by bilateral chronic deep brain stimulation (DBS) of the fornix in the hypothalamus suggests that neuromodulation of circuits involved in memory processes may have therapeutic implications in AD patients with memory decline. The primary objectives of this prospective, non-controlled, pilot study are to evaluate the feasibility and safety of DBS in AD patients with mild cognitive and memory impairment, and to evaluate the efficacy of DBS to slow down or stabilize this decline. Five patients with AD (DSM IV) diagnosed less than two years, with mild cognitive decline (MMSE 20-24), and specific impairment of episodic memory will be included in a 2-year period. The evaluation criteria for feasibility will be the proportion of patients undergoing the procedure, chronic stimulation and evaluation process without adverse event (AE). Efficacy will be evaluated using numerous cognitive and memory testing. Changes in behavioral and mood scales, and changes in hypothalamic functions (clinical, biological and hormonal assessment) will evaluate safety and tolerance. Clinical, neuro-psychological, biological and imaging assessment will be performed 3 and one month before and 3, 6, 12 and 24 months after surgery. Bilateral electrodes (Medtronic 3389) will be implanted, by MR-guided frame-based stereotaxy, in the hypothalamic part of the fornix, and then connected to the generator (Kinetra, Medtronic). Chronic high-frequency stimulation will be delivered immediately after surgery. The investigators expect to slow down, or to stabilize the spontaneous decline of MMSE and ADAS scores after 6, 12 and 24 months of stimulation. In case of efficacy, DBS might offer to AD patient the possibility to slow down/stabilize their symptoms, which no other treatment can currently offer, and to increase their quality of life.
Open-Label Extension of the Phase III Study With Tramiprosate (3APS) in Patients With Mild to Moderate...
Alzheimer's DiseaseThe purpose of this Phase III open-label extension study is to evaluate the long-term safety of Tramiprosate (3APS) in patients with mild to moderate Alzheimer's disease.
BONSAI: Biomarkers of Nonsteroidal Anti-Inflammatories
Alzheimer's DiseaseThe purpose of this study is to test the effect of ibuprofen on the levels of a number of different proteins (called biomarkers) in cerebrospinal fluid (CSF), blood, and urine to see whether ibuprofen can influence certain biomarkers associated with the progression of Alzheimer's Disease.
Study of Escitalopram Versus Placebo in the Treatment of Depressive Syndrome in Alzheimer's Disease,...
Depressive SyndromeThe goal of the present study is to compare the effectiveness of the active (S)-enantiomer of citalopram, escitalopram with placebo in the treatment of patients with depressive syndrome complicating Alzheimer's dementia (AD), vascular dementia (VD) or mixed dementia (MD), for 8 weeks of double-blind treatment.
Dopaminergic Enhancement of Learning and Memory in Healthy Adults and Patients With Dementia/Mild...
Alzheimer's DiseaseMild Cognitive Impairment1 moreThis study aims to determine whether levodopa is effective in boosting learning and memory in healthy subjects and patients with dementia or Mild Cognitive Impairment. We also examine in healthy subjects using functional magnetic resonance imaging which brain regions mediate improved learning after levodopa administration.
Safety Study of Passive Immunization for Patients With Mild to Moderate Alzheimer's Disease
Alzheimer's DiseaseThis research study will assess whether AAB-001 is safe, well tolerated and effective for use in patients with Alzheimer's Disease. AAB-001 is a new drug that is not available outside this study. AAB-001 is an antibody (a type of protein usually produced by white blood cells to destroy other substances in the body). In Alzheimer's disease a protein called amyloid gathers in the brain and is thought to cause symptoms like memory loss and confusion. It is hoped that AAB-001 will attach to the amyloid protein in your brain and help your body to remove it.
Evaluation of Safety and Tolerability of Libella Gene Therapy for Alzheimer's Disease: AAV- hTERT...
Alzheimer DiseaseUsing gene therapy to express active telomerase (hTERT) in human cells has the potential to treat many neurodegenerative diseases related to aging, including Alzheimer's disease (AD). This study will entail treating subjects with hTERT delivered via transduction using AAV. The goal is to extend the telomeres to prevent, delay, or even reverse the development of the pathology of AD. It is expected to have a direct consequence on cognitive function and quality of life in patients with neurodegenerative diseases, such as AD.
A Study to Evaluate the Pharmacokinetics and Safety of BEY2153 in Healthy Participants
Alzheimer's DiseaseThis is a first in human Phase 1 study to evaluate the safety, tolerability and pharmacokinetics with healthy young and elderly adult male volunteers after receiving single and multiple ascending dose of BEY2153.
Longitudinal Study Examining At-Home tDCS
Alzheimer DiseaseParticipants with dementia have reported improvements after receiving tDCS in a study at our lab. Although we make an effort to enroll such participants in further tDCS research studies, some participants are ineligible for further studies or simply unwilling to continue being a research participant. These same individuals, however, are interested in purchasing their own tDCS machine and have approached us for advice on how to purchase their own machine. Because these devices are commercially available, there is nothing theoretically stopping these participants from purchasing their own machine. Therefore, we have chosen to carry out a longitudinal study that will allow us to serve as an advisory role for participants who have decided to continue administering tDCS at home. We will recommend the tDCS related items that should be purchased, and train participants on how to properly administer tDCS. Monthly reports will also be collected, which will allow us to monitor the person's condition. We plan to monitor participants for at least two years. From these reports, we will be able determine to what extent tDCS is beneficial when done at home as a treatment for dementia symptoms.
