Reducing the risk of dementia can halt the worldwide increase of affected people. The multifactorial and heterogeneous nature of late-onset dementia, including Alzheimer's disease (AD), indicates a potential impact of multidomain lifestyle interventions on risk reduction. The positive results of the landmark multidomain Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) support such an approach. The World-Wide FINGERS (WW-FINGERS), launched in 2017 and including over 25 countries, is the first global network of multidomain lifestyle intervention trials for dementia risk reduction and prevention. WW-FINGERS aims to adapt, test, and optimize the FINGER model to reduce risk across the spectrum of cognitive decline-from at-risk asymptomatic states to early symptomatic stages-in different geographical, cultural, and economic settings. WW-FINGERS aims to harmonize and adapt multidomain interventions across various countries and settings, to facilitate data sharing and analysis across studies, and to promote international joint initiatives to identify globally implementable and effective preventive strategies.
Abstract-Pharmacological management of neurobehavioral disorders following traumatic brain injury (TBI) is common practice. However, the evidence available to guide this practice remains sparse. This review summarizes, in brief, the state of knowledge, organized via a time continuum from injury as well as by symptom complex. The areas of neuroprotection, hypoarousal, attention and memory deficits, aggression, agitation, depression, and mania are reviewed. The literature was searched with PubMed on the terms "traumatic brain injury" or "brain injury" with "pharmacology" (and the symptoms according to which this review is arranged). Additional searches were conducted with the specific symptoms as search terms, crossed with the therapeutic agents or drug classes discussed. Where a paucity of prospective data exists, case reports and retrospective studies are included. Studies to date have yielded minimal positive evidence for enhancing function, memory, and behavior after TBI. No single agent likely will become sentinel in the recovery process, and combination therapy in the acute and postacute settings are required. A need exists to further define the role of psychopharmacology in postacute TBI medicine and the specific characteristics of subpopulations who might benefit.
-In this paper, neural network control is presented for a rehabilitation robot with unknown system dynamics. To deal with the system uncertainties and improve the system robustness, adaptive neural networks are used to approximate the unknown model of the robot and adapt interactions between the robot and the patient. Both full state feedback control and output feedback control are considered in this paper. With the proposed control, uniform ultimate boundedness of the closed loop system is achieved in the context of Lyapunov's stability theory and its associated techniques. The state of the system is proven to converge to a small neighborhood of zero by appropriately choosing design parameters. Extensive simulations for a rehabilitation robot with constraints are carried out to illustrate the effectiveness of the proposed control.Index Terms -Adaptive neural network control, Full state feedback control, Lyapunov's direct method, Output feedback control, Rehabilitation robot.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
