An interplay between cross-cultural and psychometric factors in the Montreal Cognitive Assessment: Experience from the language of a small nation.

The present study aimed to test the hypothesis that the total word length on the Memory subtest of the Czech version of the MoCA, which is 12 syllables compared to the English version of 7 syllables, would have a significant effect on Delayed Recall scores compared to the newly created well-balanced version of the test (further MoCA-WLE). In the original Czech version of MoCA, we replaced the 12-syllable word list in the Memory subtest with a 7-syllable list (MoCA-WLE) to make it equivalent to the standard English version in this respect. We analyzed data from 83 participants in the original MoCA group (70.

Small effects of olfactory identification and discrimination on global cognitive and executive performance over 1 year in aging people without a history of age-related cognitive impairment.

Olfactory and cognitive performance share neural correlates profoundly affected by physiological aging. However, whether odor identification and discrimination scores predict global cognitive status and executive function in healthy older people with intact cognition is unclear. Therefore, in the present study, we set out to elucidate these links in a convenience sample of 204 independently living, cognitively intact healthy Czech adults aged 77.

Longitudinal assessment of ventricular volume trajectories in early-stage schizophrenia: evidence of both enlargement and shrinkage.

Background: Lateral ventricular enlargement represents a canonical morphometric finding in chronic patients with schizophrenia; however, longitudinal studies elucidating complex dynamic trajectories of ventricular volume change during critical early disease stages are sparse.

Methods: We measured lateral ventricular volumes in 113 first-episode schizophrenia patients (FES) at baseline visit (11.7 months after illness onset, SD = 12.
