Poorer Cognitive Performance (poorer + cognitive_performance)
Selected AbstractsFunctional correlates of lower cognitive test scores in essential tremor,MOVEMENT DISORDERS, Issue 4 2010Elan D. Louis MD Abstract Although motor features have been the defining element of essential tremor (ET), lower neurocognitive test scores are increasingly being recognized. However, the clinical correlates, if any, of these lower test scores remain largely unexplored. The aim of this study was to determine whether cognitive test scores in ET have any functional correlates. The Modified Mini Mental Status Examination (MMSE), Katz Activities of Daily Living (ADL) scale and Lawton Instrumental (I) ADL scale were administered to 95 cases. The Katz ADL score (rho = 0.26, P = 0.01) and Lawton IADL score (rho = 0.32, P = 0.001) were correlated with MMSE scores, such that poorer cognitive performance indicated greater dysfunction. Furthermore, cognitive test scores were a better predictor of functional disability than was tremor severity. Poorer cognitive performance in ET was associated with greater functional deficit. Cognition should enter the clinical dialog with ET patients as an issue of clinical significance. © 2010 Movement Disorder Society [source] Follow-up of adolescents born extremely preterm: cognitive function and health at 18 years of ageACTA PAEDIATRICA, Issue 9 2010Anne-Li Hallin Abstract Aim:, To compare cognitive ability, school achievement and self-perceived health aspects in adolescents born extremely preterm and term born controls. Method:, Fifty-two, out of 61, extremely preterm born adolescents (mean age 18.4 years) and 54 matched controls (mean age 18.3 years) born at full term were investigated; intelligence quotient was measured with the Wechsler Adult Intelligence Scale; cognitive flexibility, i.e. a measure of visuomotor speed and attention, with the Trail Making Test; school achievement and choice of upper secondary programmes were reported. Health aspects were investigated in a semi structured interview. Result:, The adolescents born prematurely had significantly lower IQ than the controls, mean 93 (SD 15.4) vs 106 (12.5), p < 0.001; showed slower visuomotor speed; had lower grades from compulsory school (192.7 vs 234.8, p < 0.001); and chose to a greater extent practical upper secondary school programmes. There were no differences between the groups in health care consumption, prevalence of chronic disease, allergy or infectious diseases. Conclusion:, Poorer cognitive performance, in extremely preterm born individuals, seems to persist into late adolescence. Fewer prematurely born than control chose theoretical upper secondary school programmes. However, no difference was noted regarding self-perceived health aspects. [source] Can High-Risk Older Drivers Be Identified Through Performance-Based Measures in a Department of Motor Vehicles Setting?JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 1 2006Karlene K. Ball PhD OBJECTIVES: To evaluate the relationship between performance-based risk factors and subsequent at-fault motor vehicle collision (MVC) involvement in a cohort of older drivers. DESIGN: Prospective cohort study. SETTING: Motor Vehicle Administration (MVA) field sites in Maryland. PARTICIPANTS: Of the 4,173 older drivers invited to participate in the study, 2,114 individuals aged 55 to 96 agreed to do so. These analyses focus on 1,910 individuals recruited through MVA field sites. MEASUREMENTS: Gross Impairment Screening Battery, which included Rapid Pace Walk, Head/Neck Rotation, Foot Tap, Arm Reach, Cued Recall, Symbol Scan, Visual Closure subtest of the Motor Free Visual Perception Test (MVPT), Delayed Recall, and Trail Making Test with an Abbreviated Part A and standard Part B; Useful Field of View (UFOV®) subtest 2; a Mobility Questionnaire; and MVC occurrence. RESULTS: In drivers aged 55 and older with intact vision (20/70 far visual acuity and 140° visual field), age, sex, history of falls, and poorer cognitive performance, as measured using Trails B, MVPT, and UFOV subtest 2, were predictive of future at-fault MVC involvement. After adjusting for annual mileage, participants aged 78 and older were 2.11 as more likely to be involved in an at-fault MVC, those who made four or more errors on the MVPT were 2.10 times as likely to crash, those who took 147 seconds or longer to complete Trails B were 2.01 times as likely to crash, and those who took 353 ms or longer on subtest 2 of the UFOV were 2.02 times as likely to incur an at-fault MVC. Older adults, men, and individuals with a history of falls were more likely to be involved in subsequent at-fault MVCs. CONCLUSION: Performance-based cognitive measures are predictive of future at-fault MVCs in older adults. Cognitive performance, in particular, is a salient predictor of subsequent crash involvement in older adults. High-risk older drivers can be identified through brief, performance-based measures administered in a MVA setting.

Kaller Kaller T, Boeck A, Sander K, Richterich A, Burdelski M, Ganschow R, Schulz KH. Cognitive abilities, behaviour and quality of life in children after liver transplantation. Pediatr Transplantation 2010: 14:496,503. © 2010 John Wiley & Sons A/S. Abstract:, Aims:, We investigated interrelations between cognitive abilities, behavioural problems, quality of life and disease-related variables of children after LTX. Methods:, Our sample consisted of 25 children. They were 8.5/2.8 (M/SD) years old and had received the transplant 5.5/3.1 years previously. For assessment we used well-established instruments. Results:, Liver transplanted children scored below the population mean on the cognitive as well as on the behavioural instrument and showed scores below average in the scales Self-esteem, Friends and Total Score regarding QoL. Behavioural problems were associated with poorer cognitive performance (r=,0.38 to ,0.63). QoL regarding physical well-being was correlated with sequential processing (r=0.41). Lower sequential processing scores were associated with lower QoL. Also between behavioural parameters and QoL correlations could be determined. Children with more behavioural problems experienced lower QoL (r=,0.40 to r=,0.76). Age at onset of disease showed correlations with behavioural and QoL parameters (r=,0.49 resp. r=0.44). Cognitive functioning was associated with medical complications (r=,0.44). Conclusions:, High interrelations between cognitive functioning, behavioural deficits and QoL were obtained. Especially noticeable are correlations between sequential processing and internalized behavioural functions as both are associated with left lateralized brain functioning. This relationship could indicate differential effects on brain development during the preoperative phase. [source] | ||||||||||
