Reliability and validity of the CogState computerized battery in patients with seizure disorders and healthy young adults: comparison with standard neuropsychological tests.

Authors: Bowden SC, Cook MJ, Fratti S

Journal: The Clinical Neuropsychologist

Page No.: 1-18

Year Published: 2016

OBJECTIVE: The aim was to examine the reliability and validity of two measures of learning and memory within the CogState Computerized Battery: the One Card Learning (OCL) and the Continuous Paired Associative Learning (CPAL). Comparison of various reliable change measures was also included to examine rate of correct cognitive change classification, in particular, when using […]

Prospective, Head-to-Head Study of Three Computerized Neurocognitive Assessment Tools (CNTs): Reliability and Validity for the Assessment of Sport-Related Concussion.

Limited data exist comparing the performance of computerized neurocognitive tests (CNTs) for assessing sport-related concussion. We evaluated the reliability and validity of three CNTs-ANAM, Axon Sports/Cogstate Sport, and ImPACT-in a common sample. High school and collegiate athletes completed two CNTs each at baseline. Concussed (n=165) and matched non-injured control (n=166) subjects repeated testing within 24 […]

Comparison of Cognitive Performance on the Cogstate Brief Battery When Taken In-Clinic, In-Group, and Unsupervised.

Year Published: 2015

OBJECTIVE: Repeat cognitive assessment comparing post-injury performance to a pre-injury baseline is common in concussion management. Although post-injury tests are typically administered in clinical settings, baseline tests may be conducted individually with one-on-one supervision, in a group with supervision, or without supervision. The extent to which these different test settings affect cognitive performance is not […]

The use of the Computerized Neuropsychological Test Battery (CNTB) in an efficacy and safety trial of BMY 21,502 in Alzheimer’s disease.

Authors: Cutler NR, Hironaka DY, Reich LA, Seifert RD, Shrotriya RC, Sramek JJ, Veroff AE

Journal: Annals of the New York Academy of Sciences

Volume & Issue: 695

Year Published: 1993

BMY 21,502 is a nootropic which protects memory and enhances long-term potentiation according to preclinical findings. Alzheimer’s disease (AD) patients who were diagnosed by DSM-III-R and NINCDS-ADRDA criteria were enrolled in a 12-week double-blind investigation of BMY 21,502 vs. placebo at 300 mg tid. The study design included a 1-week placebo lead-in and a 4-week […]

Efficacy and safety of BMY 21,502 in Alzheimer disease.

Year Published: 1996

OBJECTIVE: To assess the efficacy and safety of BMY 21,502, a nootropic agent, in patients with mild-to-moderate Alzheimer disease. DESIGN AND PARTICIPANTS: Sixty-nine patients with Alzheimer disease (28 men, 41 women, mean age 72 y, range 54-92, mean Mini-Mental State Examination (MMSE) score 23.5) were randomized to receive either BMY 21,502 (n = 34) or […]

Motor imagery training ameliorates motor clumsiness in children.

Authors: Maruff P, Thomas PR, Wilson PH

Journal: Journal of Child Neurology

Volume & Issue: 17 & 7

Page No.: 491-8

Year Published: 2002

Children with impaired motor coordination (or developmental coordination disorder) have difficulty representing internally the visuospatial coordinates of intended movements. We have proposed that this deficit reflects impairment in the generation of forward models of the efference copy of intended movements-the efference-copy-deficit hypothesis. In this study, we challenged this hypothesis by examining the efficacy of an […]

Mild cognitive impairment can be detected by multiple assessments in a single day.

Authors: Collie A, Darby D, Maruff P, McStephen M

Journal: Neurology

Volume & Issue: 59 & 7

Page No.: 1042-6

Year Published: 2002

BACKGROUND: Reliable detection of mild cognitive impairment (MCI), in many cases preceding AD, is important in determining the efficacy of emerging treatments. The operational definition of MCI is currently imprecise and would be improved by objective criteria. Inherent in the transition from MCI to AD is cognitive decline, which can be detected using multiple assessments […]

Status of computerized cognitive testing in aging: a systematic review.

BACKGROUND: Early detection of cognitive decline in the elderly has become of heightened importance in parallel with the recent advances in therapeutics. Computerized assessment might be uniquely suited to early detection of changes in cognition in the elderly. We present here a systematic review of the status of computer-based cognitive testing, focusing on detection of […]

BACKGROUND: Computerized cognitive testing has the potential to be an effective way to assess and monitor cognition in large neuroepidemiological studies. CogState is a game-like computerized test with demonstrated validity and reliability that has shown sensitivity to decline in older individuals over time. This study aimed to evaluate the serial usability of the test specifically […]
