Background: Montreal Cognitive Assessment is widely used in stroke to detect cognitive impairment. The superiority of it over other outcome measures has been well established. It has been cross-culturally translated and has shown excellent psychometric properties. To assess the intervention effect on cognition of Nepalese individuals with stroke using the Montreal Cognitive Assessment, an adapted Nepali version is required as the Nepalese cultural context and language are completely different than the original was developed. Thus, the objective of this study is to translate and cross-culturally adapt Montreal Cognitive Assessment in the Nepali language and see its test-retest reliability and internal consistency.
Methods: After translating and cross-culturally adapting the Montreal Cognitive Assessment into Nepali using Beaton guidelines. Its Nepali version was administered to 28 individuals with stroke twice keeping the interval of two weeks. Test-retest reliability and internal consistency were assessed using the Intraclass correlation coefficient and Cronbach's alpha.
Results: The Montreal Cognitive Assessment was translated into Nepali with significant cultural adaptations and the Nepali version demonstrated excellent psychometric properties as hypothesized. The test-retest reliability and internal Consistency were excellent. The Intraclass correlation coefficient of the total score was 0.990 and Cronbach's alpha value was 0.994 for total scores.
Conclusions: The Nepali version of Montreal Cognitive Assessment is reliable to use as a diagnostic tool for detecting cognitive impairment in patients with stroke. It is comprehensive, easy to administer and culturally appropriate.

Linking neurobiology to relatively stable individual differences in cognition, emotion, motivation, and behavior can require large sample sizes to yield replicable results. Given the nature of between-person research, sample sizes at least in the hundreds are likely to be necessary in most neuroimaging studies of individual differences, regardless of whether they are investigating the whole brain or more focal hypotheses. However, the appropriate sample size depends on the expected effect size.

Background: Electroconvulsive therapy (ECT) is a highly effective treatment for schizophrenia and mood disorders; however, most evidence is derived from the adult population, with less evidence in adolescents. We sought to determine the use of ECT in adolescents in the Institute of Mental Health (IMH) and evaluate the treatment outcome.
Methods: We conducted a retrospective naturalistic analysis of ECT registry data of patients aged from 10 to 19 years from March 2017 to March 2023.

Importance: Sleep disorders and mild cognitive impairment (MCI) commonly coexist in older adults, increasing their risk of developing dementia. Long-term tai chi chuan has been proven to improve sleep quality in older adults. However, their adherence to extended training regimens can be challenging.

Movie-watching is a central aspect of our lives and an important paradigm for understanding the brain mechanisms behind cognition as it occurs in daily life. Contemporary views of ongoing thought argue that the ability to make sense of events in the 'here and now' depend on the neural processing of incoming sensory information by auditory and visual cortex, which are kept in check by systems in association cortex. However, we currently lack an understanding of how patterns of ongoing thoughts map onto the different brain systems when we watch a film, partly because methods of sampling experience disrupt the dynamics of brain activity and the experience of movie-watching.

The cortex and cerebellum are densely connected through reciprocal input/output projections that form segregated circuits. These circuits are shown to differentially connect anterior lobules of the cerebellum to sensorimotor regions, and lobules Crus I and II to prefrontal regions. This differential connectivity pattern leads to the hypothesis that individual differences in structure should be related, especially for connected regions.
