Examining stability of independent component analysis based on coefficient and component matrices for voxel-based morphometry of structural magnetic …
2018
Independent component analysis (ICA) on group-level voxel-based morphometry (VBM) produces the coefficient matrix and the component matrix. The former contains variability among multiple subjects for further statistical analysis, and the latter reveals spatial maps common for all subjects. ICA algorithms converge to local optimization points in practice and the mostly applied stability investigation approach examines the stability of the extracted components. We found that the practically stable components do not guarantee to produce the practically stable coefficients of ICA decomposition for the further statistical analysis. Consequently, we proposed a novel approach including two steps: …
Correlation between Cognition and Balance among Middle-Aged and Older Adults Observed through a Tai Chi Intervention program
2020
Background: Age-associated decline in cognition and balance may cause severe ability loss for daily living activities among middle-aged and older adults. The relationship between cognition and balance in this aging population remains to be explored. Objective: The present study Is exploratory in nature and aimed to examine the relationship between balance (both static and dynamic components) and global cognitive function among middle-aged and older adults through Tai Chi (TC) practice as a research avenue. Methods: A short-term (12 weeks) intervention of TC was conducted among middle-aged and older adults in the community setting. Global cognitive function (using the Chinese version of the …
Cognition in Interaction : Challenges in Assessing Persons with Sensory and Multiple disabilities
2021
This article reports a qualitative study of cognitive assessments of three teenagers with sensory and multiple disabilities, including moderate to profound developmental disability. The aim was to evaluate the possibilities for adapting standardized tests and the implementation of interactional partnership in assessment. Cognitive assessments were made with an individually-adapted psychological assessment tool, the Bayley Scales of Infant and Toddler Development. The assessment situations were video-recorded and analyzed based on sociocultural theories of early interaction, dynamic assessment, and the bodily-tactile modality of cognition. The results showed that the requirements for assessm…
Ajokyvyn arviointi MoCA-menetelmällä Alzheimerin taudin varhaisvaiheessa
2019
Vertaisarvioitu Lähtökohdat Tutkimme Montreal Cognitive Assessment (MoCA) -menetelmän soveltuvuutta varhaista Alzheimerin tautia sairastavien potilaiden ajokyvyn arviointiin. Selvitimme myös menetelmän herkkyyttä tunnistaa kognitiomuutoksia. Menetelmät Tutkimus sisälsi haastattelun, kognitiivisen arvioinnin (MoCA), ajon simulaattorilla ja oman ajamisen arvioinnin. Siihen osallistui 7 potilasta ja 17 tervettä ikätoveria. Tulokset Potilaat suoriutuivat verrokkeja heikommin MoCA-testissä ja simulaattoriajossa. Arvio omasta suoriutumisesta ajossa oli heillä merkitsevästi parempi kuin verrokeilla. Potilaat saivat testipisteitä keskimäärin 18,6 ja verrokit 27,4. Simulaattoriajossa potilaat tekivä…
Motor and Cognitive Performance in Patients with Liver Cirrhosis with Minimal Hepatic Encephalopathy
2020
Minimal hepatic encephalopathy (MHE) is associated with mild cognitive impairment and frailty. This study aims to identify cognitive and motor differences in cirrhotic patients with and without MHE, and the correlations between motor signs and cognitive performance. Gait, balance, hand strength and motor speed performance were evaluated in 66 cirrhotic patients (38 without and 28 with MHE, according to the Psychometric Hepatic Encephalopathy Score (PHES). Cognitive performance was measured with the Mini-Mental State Examination, Verbal Fluency Test, Aprendizaje Verbal España-Complutense Test (TAVEC), Wechsler Adult Intelligence Scale III, Hamilton Depression and Anxiety Rating Scale and Fun…
IMPACT OF CAROTID ENDARTERECTOMY ON COGNITIVE PERFORMANCE AND DEPRESSIVE SYMPTOMS
2016
OBJECTIVES: This study aims to evaluate the impact of carotid endarterectomy (CEA) on cognitive performance in patients with severe carotid disease and depressive symptoms, and to explore the possible associations between certain demographics, clinical characteristics, and cognitive function and depression. MATERIALS AND METHODS: The study included 48 patients, who were referred for endarterectomy. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) scale, while depressive symptoms were assessed using the patient health questionnaire(PHQ-9) scale. An assessment of cognitive and depressive symptoms was performed 1–3 days before surgery, and then six months after. R…
Rakenteelliset tekijät mutkistavat väestösuhteutettujen mielenterveysindikaattorien tulkintaa
2020
Kansallisten rekisteriaineistojen käyttö väestön mielenterveyden ja mielenterveyspalvelujen laadun kuvaamiseen on lisääntynyt julkisten indikaattoripankkien myötä. nonPeerReviewed
