The importance of educational and psychological factors in Parkinson's disease quality of life

EUROPEAN JOURNAL OF NEUROLOGY, Issue 6 2002
E. Cubo
Objective: ,To define the factors correlated with quality of life (QoL) in patients with idiopathic Parkinson's disease (PD). Background: PD has a substantial impact on QoL. Although several clinical factors have been associated with QoL in PD, the influence of patient's education still remains controversial. Methodology: ,A consecutive series of patients with PD were examined using the unified Parkinson's Disease Rating Scale (UPDRS part I, II, III), Schwab and England (SE), and Hoehn and Yahr stage (H&Y). QoL was rated with the PDQ-39, cognition with the Mini-Mental State examination (MMSE), and the presence of depressive symptoms with the geriatric depression scale (GDS). Patient's characteristics, estimated cumulative levodopa dose (CLD), UPDRS, H&Y, MMSE and GDS were correlated with the PDQ-39 using univariate and multiple regression analysis. Results: ,A total of one hundred 58 patients (68 men, 90 women) with a mean age of 65.6 ± 9.3 years, PD duration of 8.1 ± 10.6 years, and education of 6.6 ± 3.9 years were included. The mean PDQ-39 was 48.8 ± 27.8, mean MMSE was 25.7 ± 4, and mean GDS was 11.7 ± 6.8. Using stepwise multiple regression analysis, the most important predictive factors were depression, UPDRS part I, UPDRS part II, and educational background, which accounted for a 61% of the variability of the PDQ-39 scores. Conclusions: ,In our PD sample, educational, behavioural, and psychological factors influenced life satisfaction more than physical ones. [source]


Psychometric attributes of the SCOPA-COG Brazilian version

MOVEMENT DISORDERS, Issue 1 2008
Francisco Javier Carod-Artal MD
Abstract Cross-cultural adaptation and independent psychometric assessment of the Scales for Outcomes in Parkinson's disease-Cognition (SCOPA-COG), Brazilian version was performed. Parkinson's disease (PD) patients were evaluated by means of the SCOPA-Motor scale, Hoehn and Yahr staging (HY), Clinical Impression of Severity Index-PD (CISI-PD), Parkinson Psychosis Rating Scale, and Hospital Anxiety and Depression Scale. Cognition was evaluated using the Mini-Mental State Examination (MMSE), Short Portable Mental Status Questionnaire (SPMSQ), and SCOPA-COG. The following attributes were explored: acceptability, scaling assumptions, reliability, precision, and construct validity. One hundred fifty-two patients were assessed (mean age, 63.2 years; disease duration, 7.8 years; median HY stage, 3). Mean SCOPA-COG and MMSE were 18.2 and 25.7, respectively. The internal consistency of the SCOPA-COG (Cronbach's alpha = 0.81; item-total correlation, 0.38,0.62) was satisfactory. While the intraclass correlation coefficient value was 0.80, weighted kappa ranged from 0.30 (dice task) to 0.72 (animal fluency task). The standard error of measurement value for the SCOPA-COG was 3.2, whereas the smallest real difference was 8.9. SCOPA-COG total scores significantly decreased as the HY stage increased (Kruskal-Wallis, P < 0.0001). Age, years of education, and PD duration (all, P < 0.001) were observed to have an independent, significant effect on the SCOPA-COG. The SCOPA-COG is a short, reliable, valid instrument that is sensitive to cognitive deficits specific to PD. © 2007 Movement Disorder Society [source]


Association between amantadine and the onset of dementia in Parkinson's disease

MOVEMENT DISORDERS, Issue 9 2006
Rivka Inzelberg MD
Abstract The objective of this study is to compare the occurrence of dementia among Parkinson's disease (PD) patients treated with amantadine (AM group) with those never exposed to it (NoAM group). PD dementia shares neuroanatomical and biochemical similarities with Alzheimer's disease (AD). Memantine, an N -methyl- D -aspartate (NMDA) receptor antagonist has been shown to be beneficial in AD. Memantine is a dimethyl derivative of amantadine, which also possesses NMDA receptor blocking properties. We hypothesized that amantadine could have a beneficial effect on the occurrence of PD dementia. PD patients attending the Movement Disorders Clinics in Hillel Yaffe, Asaf Harofe Medical Centers (Israel) and Pisa (Italy) were included. Taking the onset of dementia as the endpoint, survival curves for AM and NoAM patients were estimated by the Kaplan,Meier method. The study population consisted of 593 patients (age, 69.5 ± 9.9 years; PD duration, 9.2 ± 6.0 years; 263 patients (44%) amantadine treated). The endpoint of dementia was reached by 116 patients (20%). PD duration until dementia was significantly longer for AM patients (9.1 ± 5.7 years) than for NoAM patients (5.9 ± 4.6 years, P = 0.006). The duration of amantadine exposure positively correlated with PD duration until dementia (P = 0.0001). Survival analysis, taking dementia onset as endpoint, showed slower mental decline in AM patients (Log rank P = 0.0049, Wilcoxon P = 0.0024). Mini-Mental State Examination scores were significantly higher for AM patients than for the NoAM group (P = 0.01). Age of PD onset also significantly influenced the duration of PD until dementia. Amantadine use may delay the onset of dementia in PD patients and may attenuate its severity. © 2006 Movement Disorder Society [source]


Burden of disease related to Parkinson's disease in Spain in the year 2000

MOVEMENT DISORDERS, Issue 11 2005
Esther Cubo MD
Abstract We measured the burden caused by Parkinson's disease (PD) in Spain during the year 2000 and compared it against PD burden worldwide and in the European A subregion. Burden of disease (BoD) is an important factor in health policy. Disability-adjusted life years (DALY) as a measure of BoD is the result of adding years of life lost (YLL) and years lived with disability (YLD). The burden of PD (BPD) has not been studied in Spain. YLL were obtained from the Spanish death certificates and YLD from the estimated number of incident PD cases and the average PD duration. PD disability was calculated, using the Disability Weights for Diseases in the Netherlands. Prior PD DALY data for Europe and the world were obtained from the 2001 World Health Organization World Health Report. A discount rate of 3% and age-weighting modulation factor with K = 1 were used. In Spain, PD generated 67,582 DALY, comprising 6,351 (9.4%) YLL and 61,231 (90.6%) YLD. Most PD DALY (57.5%) occurred in the population 60 to 74 years of age. When PD DALY estimates were adjusted using the world population in 2000, Spain registered a PD DALY rate of 84 per 100,000 population, higher than both the world and European A subregion rates (24 and 35 per 100,000 population, respectively). PD burden in Spain in 2000 was high, with disability being the major contributing factor. Although BPD in Spain was greater than both world and European A subregion BPD, these differences should nevertheless be interpreted with caution. © 2005 Movement Disorder Society [source]


Freezing of Gait Questionnaire: validity and reliability of the Swedish version

ACTA NEUROLOGICA SCANDINAVICA, Issue 5 2009
M. H. Nilsson
Background,,, Patient-reported assessments of freezing of gait (FOG) in Parkinson's disease (PD), such as the FOG questionnaire (FOGQ), are needed because FOG is difficult to assess objectively. However, the measurement properties of the FOGQ have been sparsely assessed. Aim,,, To assess the measurement properties of the Swedish FOGQ, and to explore relationships between FOGQ scores and other aspects of PD. Methods,,, Thirty-seven people with PD were assessed with the FOGQ, Unified PD Rating Scale (UPDRS), Hoehn and Yahr (HY), Falls-Efficacy Scale [FES(S)], timed gait tests, and the SF-36 physical functioning (PF) scale. Results,,, Mean (SD) FOGQ item scores ranged between 1.3 and 2.1 (1.2,1.5); corrected item,total correlations ranged between 0.80 and 0.94. Reliability was 0.95. Mean (SD) and median (q1,q3) FOGQ scores were 9.6 (7.4) and 10 (2,15). Floor and ceiling effects were ,5.4%. FOGQ correlated strongest with UPDRS part II (ADL), UPDRS item 14 (freezing), and HY (rS 0.65,0.66). FOGQ scores correlated with PD duration, the Timed Up and Go test, dyskinesia, motor fluctuations, FES(S), and PF scores (rS 0.40,0.62). Fallers had higher FOGQ scores than non-fallers (median 12.5 vs 5.0). Conclusion,,, Data support the measurement properties of the Swedish FOGQ by replicating and extending previous psychometric reports. [source]
