Filter by:Beyond 60 years, the prevalence of epilepsy is estimated at approximately 1% and increases with age. In these patients, the etiology of epilepsy is unknown in 25% of cases, even up to 55% after 65 years. Although new-onset epilepsy in the elderly is associated with a vascular disease in 50% of cases, the hypothesis of an ongoing neurodegenerative process, including an Alzheimer's disease (AD), is also common. However, investigators do not have any marker that might help to identify the patients who develop epilepsy after 60 years and who might be, despite a normal cognitive functioning, already engaged in the pathophysiological process of AD. A number of data suggest a link between the pathophysiological process of AD and epileptogenesis: (i) a third of patients with epilepsy develops MA, (ii) the occurrence of epilepsy in AD is an aggravating factor for cognition, (iii) in animal models of AD, the relationship between neuronal hyperexcitability and amyloid deposits is bidirectional, the amyloid protein has a pro-seizure effect and the presence of epilepsy increases the amyloid deposits, (iv) in these models, the administration of an antiepileptic drug protects from deterioration of cognition, (v) the close relationship between amyloid and neuronal hyperexcitability might be mediated by the inflammatory processes associated with AD, and particularly the microglial activation which role in epileptogenesis has been shown elsewhere. Investigators hypothesize that in a subgroup of patients who develop epilepsy after 60 years, the occurrence of epilepsy might reflect the presence of an ongoing amyloid pathology. Our goal is to identify through biomarkers of AD in the cerebrospinal fluid of patients who develop an epilepsy after 60 years with normal MRI and normal cognition those at high risk of later developing clinically defined AD. Identifying patients with amyloid pathology which would be expressed through epilepsy before the onset of cognitive dysfunction might help to adapt both the management of seizures and of the cognitive dysfunction.
This retrospective study is a more extensive, confirmatory analysis of the cognitive and functional outcomes initially seen in 2 groups of MCI/dementia patients in Springfield, MA and compares specialized dementia care and a comprehensive treatment approach versus usual care delivered in a non-specialist setting. The first group of patients (n= 328) was seen by a dementia specialist, who utilized a standardized assessment and treatment protocol (CNS). This included comprehensive identification and treatment of hypoxia, sleep-disorders, and other cognitively-impairing metabolic conditions as well as maximally- dosed FDA-approved medications for dementia, depression, and PBA. The second group of patients (n= 280) was seen by non-dementia specialists in the community and received usual care which did not include comprehensive assessment or treatment of underlying metabolic derangements or maximal utilization of currently available medications. This study, evaluating date from a larger cohort (n>800) of specialist-treated cognitively-impaired patients, will further examine the hypothesis that a comprehensive dementia treatment protocol yields cognitive stabilization and/or improvement using already available dementia drugs when compared with usual community care.
The primary objective of the study is to evaluate the effects of hepatic impairment on the pharmacokinetics (PK) of E2609 after a single dose administration.
This study is a retrospective review of the data collected in a previously completed randomized, controlled trial (RCT) entitled "Memantine and Comprehensive, Individualized, Patient Centered Management of Alzheimer's Disease: A Randomized Controlled Trial" (NCT00120874). As part of the previously completed RCT, participants with Alzheimer's Disease (AD) were randomly placed into one of two groups: memantine, or memantine plus an individualized management program consisting of home visits, educational sessions for caregivers, and a caregiver support group. Participants received the study intervention for 28 weeks; study follow-up lasted for 52 weeks. The collected data from the existing study books from the 28 week treatment portion of the RCT will be carefully examined with respect to each of the research questions for the present retrospective study.
The study will examine the impact on cognitive reserve of a pharmacist-physician patient-centered medication therapy management intervention to address inappropriate medication use as identified by the Beers 2015 list. By bolstering cognitive reserve, this project will directly address the National Alzheimer's Project Act 2015 priorities serving to delay onset of symptoms in preclinical dementia. The results of this study will provide valuable insights on how to expand this intervention to reduce the prevalence and associated healthcare costs of symptomatic Alzheimer's disease.
The purpose of this study is to examine therapeutic efficacy of categorical language fluency smartphone game application in mild cognitive impairment and mild Alzheimer's dementia.
This study intends to use Play Intervention for Dementia (PID) to promote cognitive functions of people with early to moderate dementia. This is a cluster randomized controlled trial aims to recruit 38 participants from two study sites. Participants will be randomly allocated into intervention or wait-list controlled groups. Both groups will receive the same content of PID programme at different time. The PID consists of 12 weekly sessions. Each session lasts for 45-75 minutes. The PID will be facilitated by a play specialist, trained elderly volunteers, and centre staffs. Cognitive functions will be evaluated with Montreal Cognitive Assessment, Fuld Object Memory Evaluation and Modified Verbal Fluency Test, conducted by a trained research assistant blinded to group allocation. Centre staffs (not involved in the PID) will be interviewed. Every alternate session will be video-taped for understanding the experience of the participants in the PID programme.
The proposed study is designed to evaluate the performance of the ALTOIDA™ 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 ALTOIDA™ Neuro Motor Index (NMI) prognosis classifiers, the subjects making up the training sets must be well characterized as to their clinical diagnosis, and 2) all ALTOIDA™ tests must be performed and reproduced in real-world clinical settings. Although there is already a large body of peer-reviewed scientific literature demonstrating that certain digital biomarker patterns are associated with certain neurologic conditions, the utilization of such tools for the evaluation of neurologic disorders is still considered an emerging science and therefore in the investigational stage. Although this protocol will report on brain patterns of certain neurologic conditions such as cognitive impairment and Alzheimer's disease, based on patterns published in peer-reviewed journals, such findings are not considered stand alone or diagnostic per se and should always be considered by the primary physician in conjunction with the patient's clinical condition. These data should only be used as additional information to add to the primary physician's diagnostic impression.
This is a randomized, double-blind (Investigator and subject-blinded) placebo-controlled, multiple, ascending-dose study to evaluate the safety, tolerability, and pharmacokinetic profile of BPN14770 in healthy young and elderly male and female subjects and to provide a preliminary assessment of the cognitive effects of BPN14770 in healthy elderly subjects.
The present study aimed at measuring cerebral changes in Alzheimer Disease (AD) patients, who responded to strict physiological criteria typical of AD pathology. The objective of the present study was to identify the earliest alterations in cerebral connections that could contribute to the initial episodic memory impairment.
