    Background: The Progressive Supranuclear Palsy Rating Scale is a prospectively validated physician-rated measure of disease severity for progressive supranuclear palsy. We hypothesized that, according to experts' opinion, individual scores of items would differ in relevance for patients' quality of life, functionality in daily living, and mortality. Thus, changes in the score may not equate to clinically meaningful changes in the patient's status. Objective: The aim of this work was to establish a condensed modified version of the scale focusing on meaningful disease milestones. Methods: Sixteen movement disorders experts evaluated each scale item for its capacity to capture disease milestones (0 = no, 1 = moderate, 2 = severe milestone). Items not capturing severe milestones were eliminated. Remaining items were recalibrated in proportion to milestone severity by collapsing across response categories that yielded identical milestone severity grades. Items with low sensitivity to change were eliminated, based on power calculations using longitudinal 12-month follow-up data from 86 patients with possible or probable progressive supranuclear palsy. Results: The modified scale retained 14 items (yielding 0–2 points each). The items were rated as functionally relevant to disease milestones with comparable severity. The modified scale was sensitive to change over 6 and 12 months and of similar power for clinical trials of disease-modifying therapy as the original scale (achieving 80% power for two-sample t test to detect a 50% slowing with n = 41 and 25% slowing with n = 159 at 12 months). Conclusions: The modified Progressive Supranuclear Palsy Rating Scale may serve as a clinimetrically sound scale to monitor disease progression in clinical trials and routine

    Parkinson’s disease (PD) is the second most frequent neurodegenerative disease of people who are beyond 50 years of age. People with PD (PwP) suffer from a large variety of motor and non-motor symptoms resulting in reduced health-related quality of life (HR-QoL). In the last two decades, alexithymia was identified as an additional non-motor symptom in PD. Alexithymia is defined as a cognitive affective disturbance resulting in difficulty to identify and distinguish feelings from bodily sensations of emotional arousal. In PD, the frequency of patients suffering of alexithymia is increased compared to healthy controls. The aim of the present study was to determine the relationship of alexithymia to HR-QoL of the PwP and caregiver burden of the corresponding caregiver. This cross-sectional questionnaire-based study used disease specific questionnaires for HR-QoL and caregiver burden. In total 119 PwP and their corresponding caregivers were included in the study. HR-QoL of the PwP correlated significantly with alexithymia (p < 0.001), especially the sub-components “identifying feelings” (p < 0.001) and “difficulties describing feelings” (p = 0.001). Caregiver burden also correlated significantly with PwP alexithymia (p < 0.001). However, caregiver burden was associated with sub-components “identifying feelings” (p < 0.008) and “external oriented thinking” (p < 0.004). These data support the importance of alexithymia as a non-motor symptom in PD

    Analysis of Transition of Patients with Parkinson’s Disease into Institutional Care: A Retrospective Pilot Study

    No full text
    Parkinson’s disease (PD) is a neurodegenerative disease which gives a person a high risk of becoming care-dependent. During disease progression, the amount of care concerning activities of daily living can increase, possibly resulting in transition of the people with Parkinson’s disease (PwP) to a care facility. However, there is a lack of knowledge concerning the factors leading to institutionalization of PwP and the consequences for them and their informal caregivers. The aim of this cross-sectional retrospective study was to investigate reasons leading to the transition into an institutional care facility, the process of decision-making and its effects on PwP symptoms and caregiver burden. Participating PwP had to be institutionalized for at most one year after transition at study inclusion. Participants completed a range of semiquantitative questionnaires as well as the caregiving tasks questionnaire. Fourteen patient–caregiver pairs were included. PwP suffered from late-stage PD symptoms with high dependence on help, experiencing several hospitalizations before transition. Analyses revealed a significant decrease in caregiver burden and depressive symptoms of the caregivers after PwP institutionalization. Factors influencing the transition were, e.g., fear of PwP health issues and concerns about caregivers’ health. This study presents new insights into the process of institutionalization and its influence on caregiver burden, including aspects for discussions of physicians with PwP and their caregivers for counselling the decision to move to institutional care

    Relationship Satisfaction in People with Parkinson’s Disease and Their Caregivers: A Cross-Sectional Observational Study

    Parkinson’s disease (PD) is a neurodegenerative disorder, which leads to reduced health-related quality of life (HR-QoL) and autonomy in advanced stages of the disease. Hence, people with PD (PwPD) are in need of help, which is often provided by informal caregivers, especially spouses. This might influence the relationship satisfaction in patients and their spousal caregivers. Additionally, previous studies have shown that a reduced relationship satisfaction may result in mental disorders and reduced physical health. The aim of this study is to identify factors influencing PwPD and their caregivers’ relationship satisfaction in a cross-sectional observational study. Analyses revealed an overall satisfying relationship, measured by the Quality of Marriage Index, in PwPD (n = 84) and their caregivers (n = 79). Relationship satisfaction in PwPD mildly decreased with reduced HR-QoL and more severe depressive symptoms. Reduced relationship satisfaction in caregivers was significantly associated with decreased HR-QoL, higher caregiver burden, more severe depressive symptoms and increased neuropsychiatric symptoms in PwPD. Further studies are needed to investigate the influence of the identified factors over time and if relationship satisfaction has a reciprocal impact on caregiver burden, HR-QoL as well as mental and physical health

    Neuropsychological assessment needs a more profound grounding in psychometric theory. Specifically, psychometrically reliable and valid tools are required, both in patient care and in scientific research. The present study examined convergent and discriminant validity of some of the most popular indicators of executive functioning (EF). A sample of 96 neurological inpatients (aged 18–68 years) completed a battery of standardized cognitive tests (Raven’s matrices, vocabulary test, Wisconsin Card Sorting Test, verbal fluency test, figural fluency test). Convergent validity of indicators of intelligence (Raven’s matrices, vocabulary test) and of indicators of EF (Wisconsin Card Sorting Test, verbal fluency test, figural fluency) were calculated. Discriminant validity of indicators of EF against indicators of intelligence was also calculated. Convergent validity of indicators of intelligence (Raven’s matrices, vocabulary test) was good (rxtyt = 0.727; R2 = 0.53). Convergent validity of fluency indicators of EF against executive cognition as indicated by performance on the Wisconsin Card Sorting Test was poor (0.087 ≤ rxtyt ≤ 0.304; 0.008 ≤ R2 ≤ 0.092). Discriminant validity of indicators of EF against indicators of intelligence was good (0.106 ≤ rxtyt ≤ 0.548; 0.011 ≤ R2 ≤ 0.300). Our conclusions from these data are clear-cut: apparently dissimilar indicators of intelligence converge on general intellectual ability. Apparently dissimilar indicators of EF (mental fluency, executive cognition) do not converge on general executive ability. Executive abilities, although non-unitary, can be reasonably well distinguished from intellectual ability. The present data contribute to the hitherto meager evidence base regarding the validity of popular indicators of EF

    Parkinson’s disease (PD) is a slowly progressive neurodegenerative movement disorder that leads to impairments in activities of daily living. In addition to reducing patients’ quality of life, this disease also affects caregivers’ well-being. Until recently, caregiver burden was mainly assessed by generic questionnaires, which do not take the characteristics of the chronic disease into consideration. In the case of PD, this issue has been addressed by the introduction of the “Parkinson’s disease caregiver burden” questionnaire (PDCB). Data on longitudinal trajectories of caregiver burden are still missing in the literature. In this study, we assessed the one-year trajectory of caregiver burden by the PDCB as a disease-specific questionnaire. Further, gender-specific aspects of caregiver burden were analyzed by applying a caregiver task questionnaire. PDCB total score (n = 84 patients and caregivers) did not significantly change from baseline (30.4) to one year at follow-up (31.5). No significant difference was detected between female and male caregivers in global burden and-specific caregiver tasks. Our data showed only a mild increase of caregiver burden in the timeframe of one year. Gender-specific differences do not seem to impact-specific caregiver tasks in the presented study population

    BackgroundParkinson’s disease (PD) is the second most frequent neurodegenerative disease of the elderly. Patients suffer from various motor and non-motor symptoms leading to reduced health-related quality of life (HRQOL) and an increased mortality. Their loss of autonomy due to dementia, psychosis, depression, motor impairments, falls, and swallowing deficits defines a phase when palliative care interventions might help to sustain or even improve quality of life.ObjectiveThe aim of this study was to investigate the current status of palliative care implementation and quality of life in a local cohort of advanced PD patients in order to frame and improve future care.Methods76 geriatric patients with advanced idiopathic PD meeting the inclusion criteria for palliative care interventions were clinically evaluated by neurological examination using Movement Disorders Society Unified Parkinson’s Disease Rating Scale, Barthel Index, Montreal Cognitive Assessment Test, and a structured interview concerning palliative care implementation.ResultsHRQOL is severely reduced in our cohort of geriatric advanced PD patients. We found motor deficits, impairment of activities of daily living, depression, and cognitive decline as most relevant factors determining decreased HRQOL. Only 2.6% of our patients reported present implementation of palliative care. By contrast, 72% of the patients indicated an unmet need for palliative care.ConclusionQuality of life is dramatically affected in advanced PD patients. However, we found palliative care to be implemented extremely rare in their treatment concept. Therefore, geriatric patients suffering from advanced PD should be enrolled for palliative care to provide adequate and holistic treatment which may improve or sustain their quality of life

    To explore the correlations of botulinum toxin (BT) therapy with dysphagia, we wanted to study a group of cervical dystonia (CD) patients with optimised BT therapy during a prolonged period of time to record their dysphagia frequency, severity and duration, to study potential risk factors and try to avoid it by BT application with ultrasound guidance. BT therapy of 75 CD patients (23 males, 52 females, age 60 ± 12 years, BT total dose 303.5 ± 101.5 uMU) was retrospectively analysed for 1 year. BT therapy was optimised prior to the observation period. Dysphagia was noticed by one fifth of the patients. In those patients, it only occurred in about one third of the injection series. It was never associated with a functional deficit and lasted several days to 2 weeks. It was not related to patient age or gender, BT total dose, BT dose in the sternocleidomastoid muscle, BT dose in the sternocleidomastoid and scalenii muscles, by BT therapy with bilateral sternocleidomastoid muscle injections or BT therapy with abobotulinumtoxinA. Ultrasound guidance was not able to prevent it. Further prospective studies will be necessary to study underlying dystonia associated swallowing abnormalities as a potentially predisposing factor

    In an industrial society, the proportion of geriatric people increases with rising age. These people are likely to use polypharmacy and experience medical emergencies. However, their emergency care can be complicated by unclear comorbidities and medication. The aim of this prospective interventional study was to assess the demand for a drug safety tool in clinical practice and to analyze whether the emergency box can improve acute care in a geriatric cohort. Therefore, emergency room (ER) doctors in a German tertiary hospital recorded the number of geriatric patients lacking medical information and its impact on diagnostics/treatment. Furthermore, the emergency box was distributed to patients on the neurological ward and their current drug safety concepts were assessed. After 6 months, we evaluated in a follow-up whether the tool was helpful in emergency cases. Our study revealed that 27.4% (n = 28) of the patients came to the ER without their medical information, which caused a relevant delay or possible severe complications in 11.8% (n = 12). The emergency box was perceived as easily manageable and 87.9% (n = 109) of the participants wanted to keep it after the study. Subjectively, participants benefitted in emergencies. In conclusion, the emergency box is a cheap tool that is easy to use. It can save valuable time in emergencies and increases the safety of geriatric patients
