The Neurocognitive Profile: A High Efficiency Integrated Brain-Behavior Assay

描述（由申请人提供）：神经认知功能的改变在许多睡眠、神经和精神疾病中起着重要作用，并可能对生活质量、治疗效果、康复以及工作和正常日常活动的能力产生重大影响。目前可用于神经认知调查的方法包括传统的神经心理学评估（例如Halstead-Reitan， Wechsler记忆电池），神经生理学测量（例如脑电图，多次睡眠潜伏期测试）和行为测试（例如持续表现测试，精神运动警惕性测试），这些方法耗时，昂贵并且通常需要大量的技术专长来管理和解释。警觉性和记忆分析（AMP）系统将神经生理、行为和主观测量集成在一个平台中，用于定量评估神经认知功能，包括警觉性、注意力、学习和记忆。AMP采用多变量方法，将脑电图、神经心理测试和有效的自我报告清单结合在一套易于管理的协议中。初步调查显示，AMP可用于表征与健康受试者睡眠剥夺相关的警觉性、学习和记忆的变化，并提供识别这些变化的生物行为分析

DESCRIPTION (provided by applicant): Alterations in neurocognitive function play a major role in numerous sleeps, neurological and psychiatric disorders and can have a significant impact on quality of life, treatment efficacy, rehabilitation and ability to function at work and in normal daily activities. The methods currently available for neurocognitive investigations including traditional neuropsychological assessment (e.g. Halstead-Reitan, Wechsler memory battery), neurophysiological measures (e.g. electroencephalogram, Multiple Sleep Latency Test) and behavioral tests (e.g. Continuous Performance Test, Psychomotor Vigilance Test) are time-consuming, expensive and often require substantial technical expertise to administer and interpret. The Alertness and Memory Profiling (AMP) system integrates neurophysiological, behavioral and subjective measures in a platform designed for quantitative assessment of neurocognitive functions including alertness, attention, learning and memory. The AMP employs a multivariate approach, combining EEG, neuropsychological tests and validated self-report inventories in an easy-to-administer set of protocols. Initial investigations revealed that AMP could be used to characterize the changes in alertness, learning and memory associated with sleep deprivation in healthy subjects and to provide a biobehavioral assay that identified those Individuals most and least susceptible to the effects of sleep deprivation. The AMP also proved sensitive and specific in discriminating patients with the highly prevalent, under-diagnosed Obstructive Sleep Apnea (OSA) from healthy subjects. The AMP characterized individual profiles of alertness and memory impairment and quantified the amelioration of some cognitive impairments following treatment with CPAP. Four neurocognitive factors were derived from the AMP data: sustained attention, processing speed, verbal memory and visuospatial memory. Preliminary investigations with the AMP prototype systems have resulted in inquiries from a wide range of researchers and clinicians interested in applying the AMP to investigations in sleep medicine, drug addiction, pharmaceutical evaluation, forensic investigations, ergonomics, sports medicine, military applications, education/training evaluations, and occupational medicine. The plan for the Phase I is to build upon this foundation of work in the area of sleep medicine, and extend the development of AMP platform to accommodate the range of potential applications and to take the next step in the evolution of the AMP product in a clinical applications study in collaboration with the New York University sleep laboratory.
