The illness experience of persons with Parkinson's Disease

Background. Parkinson's disease is a chronic, progressive, age-related, neurodegenerative disorder with no known cause or promising cure. While substantial information is known about the pathophysiology of Parkinson's disease, little is known about the illness experience of persons living with the disease. The purpose of this study was to understand how persons with Parkinson's disease construct their illness experience and manage living with their illness on a daily basis. ^ Method. A qualitative study with an ethnographic approach employed the strategies of participant observations and fieldwork. Field data were generated from a two year exposure to two Parkinson's disease support groups in east Texas. Open-ended semi-structured interviews with seven men and seven women with Parkinson's disease were also conducted. These data were combined and analyzed using thematic analysis. ^ Findings. The illness experience is described through the metaphor "Sailing the Sea in The Eye of the Storm." This metaphor served as the overarching theme that covered the two interacting content themes of the voyage of Daily Negotiations in the Midst of Uncertainty and Reconstruction of the Self with Parkinson's Disease. Daily negotiations incorporated navigating daily activities with the uncertainty of both the progression and daily vicissitudes of the disease. Participants described their symptoms as progressive imprisonment that interfered with daily activities. The progressive nature of the disease required the participants to reconstruct their perceptions of themselves. Reconstructing the self involved the paradoxical balancing of preserving the self while simultaneously releasing aspects of the former self to reconstruct the self with Parkinson's disease. This process was reflected in four exemplars: I Know Me." "It's Still Me," "See Me." and "Remember Me." ^ Conclusions. This qualitative study illuminated the struggle of persons in dealing with the uncertainties and fluctuations of Parkinson's disease and the process of reconstructing their perceptions of themselves. The meaning and reconstruction of the illness experience expressed by participants will inform understanding beyond the disease itself to the illness experience that these participants must deal with on a daily basis. ^

Effects of treatment on orienting in Parkinson disease

Parkinson disease (PD) is a movement disorder affecting over one million Americans, and 1% of our population over 60 years of age. Currently, PD has an unknown cause, no predictive biomarker, and no cure, yet there are effective treatments (medicine and surgery) to chronically manage the motor symptoms. But, PD patients also develop cognitive symptoms (e.g., distractibility, executive dysfunction) that remain untreated or may decline as a result of treating the motor symptoms. To address this important issue, I measured covert orienting of attention and overt eye movements in PD patients to assess the patients' ability to automatically detect stimuli in their visual field, to predict and attend to where the stimuli would appear, and to volitionally look somewhere else. ^ PD patients completed the cognitive tasks under multiple treatment conditions, and their performance was compared to healthy adults. PD patients first completed the tasks after they had withdrawn from medication. Their unmedicated performance revealed exaggerated automatic orienting, poor predictability, and weak volitional orienting. PD patients then repeated the tasks while medication was giving its peak benefit. The medication returned automatic covert orienting toward normal but did not improve volitional covert orienting. Several PD patients completed the tasks a third time after receiving surgery (specifically, implantation of stimulating electrodes in a subcortical brain region to alleviate motor symptoms). The stimulation (without medication) returned automatic orienting toward normal, did not change predictability, and further impaired volitional orienting. Taken together, treatments prescribed to alleviate the motor symptoms (a patient's primary concern) only improve some cognitive functions. Future studies may establish criteria to predict which patients are more likely to have cognitive benefit from medication over surgery, or vice versa. ^ I have also hypothesized an anatomical model relating orienting circuitry to abnormal PD circuitry and the therapeutic targets. My results suggest medication is more effective restoring the orienting circuitry than stimulation. Further, automatic and volitional orienting abilities seem to be modulated independently, which differs from an earlier model proposing a dependent, inverse relationship. My results are further discussed in terms of response inhibition, response selection, and the location of the selection. ^

A comparison of adherence with minocycline treatment in Parkinson's disease and rheumatoid arthritis clinical trials

Background: Little is known about the effects on patient adherence when the same study drug is administered in the same dose in two populations with two different diseases in two different clinical trials. The Minocycline in Rheumatoid Arthritis (MIRA) trial and the NIH Exploratory Trials in Parkinson's disease (NET-PD) Futility Study I provide a unique opportunity to do the above and to compare methods measuring adherence. This study may increase understanding of the influence of disease and adverse events on patient adherence and will provide insights to investigators selecting adherence assessment methods in clinical trials of minocycline and other drugs in future.^ Methods: Minocycline adherence by pill count and the effect of adverse events was compared in the MIRA and NET-PD FS1 trials using multivariable linear regression. Within the MIRA trial, agreement between assay and pill count was compared. The association of adverse events with assay adherence was examined using multivariable logistic regression.^ Results: Adherence derived from pill count in the MIRA and NET-PD FS1 trials did not differ significantly. Adverse events potentially related to minocycline did not appear useful to predict minocycline adherence. In the MIRA trial, adherence measured by pill count appears higher than adherence measured by assay. Agreement between pill count and assay was poor (kappa statistic = 0.25).^ Limitations: Trial and disease are completely confounded and hence the independent effect of disease on adherence to minocycline treatment cannot be studied.^ Conclusion: Simple pill count may be preferred over assay in the minocycline clinical trials to measure adherence. Assays may be less sensitive in a clinical setting where appointments are not scheduled in relation to medication administration time, given assays depend on many pharmacokinetic and instrument-related factors. However, pill count can be manipulated by the patient. Another study suggested that self-report method is more sensitive than pill count method in differentiating adherence from non-adherence. An effect of medication-related adverse events on adherence could not be detected.^

Markov blanket-based approach for learning multi-dimensional Bayesian network classifiers: An application to predict the European Quality of Life-5 Dimensions (EQ-5D) from the 39-item Parkinson's Disease Questionnaire (PDQ-39)

Multi-dimensional Bayesian network classifiers (MBCs) are probabilistic graphical models recently proposed to deal with multi-dimensional classification problems, where each instance in the data set has to be assigned to more than one class variable. In this paper, we propose a Markov blanket-based approach for learning MBCs from data. Basically, it consists of determining the Markov blanket around each class variable using the HITON algorithm, then specifying the directionality over the MBC subgraphs. Our approach is applied to the prediction problem of the European Quality of Life-5 Dimensions (EQ-5D) from the 39-item Parkinson’s Disease Questionnaire (PDQ-39) in order to estimate the health-related quality of life of Parkinson’s patients. Fivefold cross-validation experiments were carried out on randomly generated synthetic data sets, Yeast data set, as well as on a real-world Parkinson’s disease data set containing 488 patients. The experimental study, including comparison with additional Bayesian network-based approaches, back propagation for multi-label learning, multi-label k-nearest neighbor, multinomial logistic regression, ordinary least squares, and censored least absolute deviations, shows encouraging results in terms of predictive accuracy as well as the identification of dependence relationships among class and feature variables.

Servicio ubicuo de estimulación cognitiva orientado a personas con enfermedad de Parkinson

Este trabajo de investigación detalla el diseño y evaluación de un servicio de e-salud cuyo objetivo es mejorar la estimulación y seguimiento de personas con un trastorno cognitivo. Con este fin, se ha desarrollado un protocolo de transferencia de mensajes que facilita la provisión de un servicio telemático para personas afectadas de Parkinson, pudiendo así realizar estimulación cognitiva personalizada, de forma ubicua, mediante un dispositivo fácil de usar como un tablet Android. Asimismo, este servicio permite a los terapeutas adaptar y monitorizar de forma segura la terapia, vía web, beneficiándose así de una mejor calidad en el seguimiento efectivo de cada paciente. El sistema ha sido evaluado satisfactoriamente durante tres meses con 10 pacientes entre 59 y 77 años. La solución resultante es fácilmente integrable con otras terapias complementarias y puede ser adaptada para otros deterioros cognitivos, como el debido a la enfermedad de Alzheimer o el deterioro cognitivo leve.
