The Montreal Cognitive Assessment, MoCA: A Brief Screening Tool For Mild Cognitive Impairment
Ziad S. Nasreddine,Natalie A. Phillips,Valérie Bédirian,Simon Charbonneau,Victor Whitehead,Isabelle Collin,Jeffrey L. Cummings,Howard Chertkow +7 more
TL;DR: A 10‐minute cognitive screening tool (Montreal Cognitive Assessment, MoCA) to assist first‐line physicians in detection of mild cognitive impairment (MCI), a clinical state that often progresses to dementia.
Journal ArticleDOI
Validity of a novel computerized cognitive battery for mild cognitive impairment.
Tzvi Dwolatzky,Victor Whitehead,Glen M. Doniger,Ely S. Simon,Avraham Schweiger,Dena H. Jaffe,Howard Chertkow +6 more
TL;DR: Mindstreams tests are effective in detecting MCI, providing a comprehensive profile of cognitive function, and the enhanced precision and ease of use of these computerized tests make the NeuroTrax system a valuable clinical tool in the identification of elderly at high risk for dementia.
Journal ArticleDOI
Multilingualism (but not always bilingualism) delays the onset of Alzheimer disease: evidence from a bilingual community.
Howard Chertkow,Victor Whitehead,Natalie A. Phillips,Christina Wolfson,Julie Atherton,Howard Bergman +5 more
TL;DR: A small but significant protective effect of more than 2 languages spoken is found in bilinguals overall in relation to age at diagnosis or age at symptom onset, but the results mirrored those of Bialystok et al with 2 or more languages delaying the diagnosis of Alzheimer disease by almost 5 years.
Journal ArticleDOI
The nature of lexico-semantic processing deficits in mild cognitive impairment.
TL;DR: Results suggest that intentional access to semantic memory is impaired before automatic access, and suggest that lexico-semantic impairments in the MCI group may be related to inhibition deficits during semantic search.
Journal ArticleDOI
On the status of object concepts in aphasia
TL;DR: It is suggested that a nonverbal (as well as verbal) semantic memory deficit occurs in a subgroup of patients with single word comprehension disturbance due to aphasia, and this may reflect general severity of language impairment as well as damage to certain localized brain regions.
