Background: Multiple sclerosis (MS) cognitive tests are resource intensive and limited by practice effects that prevent frequent retesting. Brief, reliable and valid monitoring tools are urgently needed to detect subtle, subclinical cognitive changes in people with MS. Cognitive monitoring over time could contribute to a new definition of disease progression, supplementing routine clinical monitoring. Methods: […]

BACKGROUND: Computerized cognitive rehabilitation training (CCRT) may be beneficial for alleviating persisting neurocognitive deficits in Ugandan severe malaria survivors. We completed a randomized controlled trial of CCRT for both severe malaria and non-malaria cohorts of children. METHODS: 150 school-age severe malaria and 150 non-malaria children were randomized to three treatment arms: 24 sessions of Captain’s […]

Episodic Memory and Learning Dysfunction Over an 18-Month Period in Preclinical and Prodromal Alzheimer’s Disease.

Authors: Ames D, Baker JE, Jaeger J, Lautenschlager NT, Lim YY, Maruff P, Masters CL, Pietrzak RH, Robertson J, Rowe CC, Snyder PJ, Villemagne VL

Journal: Journal of Alzheimer's disease : JAD

DOI: 10.3233/JAD-180344

Year Published: 2018

Recent meta-analyses suggest that episodic memory impairment associated with preclinical Alzheimer’s disease (AD) equates to 0.15-0.24 standard deviations below that of cognitively healthy older adults. The current study aimed to characterize impairments in verbal acquisition and recall detectable at a single assessment, and investigate how verbal learning and episodic memory deteriorates in preclinical AD. A […]

Computerized Cognitive Testing for Use in Clinical Trials: A Comparison of the NIH Toolbox and Cogstate C3 Batteries.

Authors: Buckley RF, Burnham S, Dekhtyar M, Martin C, Papp KV, Rentz DM, Sparks KP, Sperling RA

Journal: The Journal of Prevention of Alzheimer's Disease

DOI: 10.14283/jpad.2017.1.

Year Published: 2018

BACKGROUND As prevention trials for Alzheimer’s disease move into asymptomatic populations, identifying older individuals who manifest the earliest cognitive signs of Alzheimer’s disease is critical. Computerized cognitive testing has the potential to replace current gold standard paper and pencil measures and may be a more efficient means of assessing cognition. However, more empirical evidence about […]

Effects of Recent Alcohol Consumption Level on Neurocognitive Performance in HIV+ Individuals.

Authors: Douglas-Newman KR, Kranzler HR, Pond T, Smith RV, Spiers MV

Journal: Addictive Disorders & their Treatment

DOI: 10.1097/ADT.0000000000000109

Year Published: 2017

OBJECTIVES: Although HIV+ individuals may be at increased risk of alcohol-related cognitive impairment, the relations between drinking level and cognitive performance in these individuals are not well understood. We examined whether higher levels of recent drinking in HIV+ individuals were associated with poorer cognitive performance, particularly in executive functioning (EF) and memory. METHODS: We administered […]

Year Published: 2012

BACKGROUND: The viability and usefulness of cognitive assessment in acute stroke have been questioned, with practical challenges arising from the focal nature of neurological deficits as well as heterogeneity in arousal state. We aimed to test whether acute measures of attention correlate with attentional function at 3 months post-stroke. METHODS: Patients with confirmed stroke completed […]
