RESUMO
ABSTRACT Introduction: Mild Cognitive Impairment (MCI) is common in Parkinson's Disease (PD). Few studies have compared the Health-Related Quality of Life (HRQoL) in patients with and without MCI due to PD (PD-MCI), and its correlation to patients' subjective cognitive and communicative difficulties has not been explored. Objective: We aimed to compare HRQoL in PD-MCI and PD without MCI (PD-nMCI), and explore its possible relationship to subjective cognitive and communicative complaints. Methods: We included 29 PD-nMCI and 11 PD-MCI patients. The HRQoL was assessed with the Parkinson's Disease Questionnaire-39 (PDQ-39): its Cognition dimension was used as a measure of subjective cognitive complaints, its Communication dimension for subjective communicative complaints, and the summary index (PDQ-39 SI) as an indicator of HRQoL. Non-parametric partial correlations between the Cognition and Communication dimensions, and the adjusted PDQ-39 SI were conducted. Results: PD-MCI patients had greater subjective cognitive and communicative complaints and worse HRQoL than PD-nMCI patients. In the PD-MCI group, both subjective cognitive and communicative complaints exhibited significant direct correlations with the adjusted HRQoL scores. Conclusions: HRQoL seems to be affected in PD-MCI, and it might be influenced by greater subjective cognitive and communicative complaints. Including patient-reported outcome measures of HRQoL, and providing cognitive and speech rehabilitation, as well as psy-chotherapeutic strategies to face these deficits can enhance the patient-centred approach in PD.
RESUMEN Introducción: El deterioro cognitivo leve (DCL) es frecuente en la enfermedad de Parkinson (EP). Pocos estudios han comparado la calidad de vida relacionada con la salud (CVRS) en pacientes con DCL debido a EP (EP-DCL) sin explorar la relación entre la CVRS y las quejas subjetivas cognitivas y comunicativas de los pacientes. Objetivo: Comparar la CVRS en EP-DCL y EP sin DCL (EP-nDCL) explorando sus posibles relaciones con las quejas subjetivas cognitivas y comunicativas. Métodos: Se incluyó a 29 EP-DCL y 11 EP-nDCL. La CVRS se evaluó con el cuestionario PDQ-39: su dimensión Cognición se usó como medida de las quejas subjetivas cognitivas; su dimensión Comunicación, como medida de las quejas subjetivas comunicativas y su puntuación resumen (PDQ-39 SI), como indicador de CVRS. Se realizaron correlaciones parciales no paramétricas entre el PDQ-39 SI ajustado y las dimensiones Cognición y Comunicación. Resultados: Los pacientes EP-DCL presentaron una peor CVRS y mayores quejas subjetivas cognitivas y comunicativas. En el grupo EP-DCL, tanto las quejas subjetivas cognitivas como las comunicativas mostraron correlaciones directas significativas con la puntuación de CVRS ajustada. Conclusiones: La CVRS de los pacientes con EP-DCL parece estar afectada e influida por las quejas subjetivas en cognición y comunicación. Incluir los resultados de CVRS reportados por los pacientes, proveer rehabilitación cognitiva y del lenguaje y estrategias de psicoterapia para afrontar dicho déficit podrían mejorar el abordaje centrado en el paciente en la EP.
RESUMO
PURPOSE: The present study aims to explore the association between the quality of life (QoL) score and the clinical and sociodemographic variables in patients with the PSEN1-E280A mutation. We also seek to evaluate the differences between the QoL reported by the patients (P-QoL) and the scores reported by the caregivers (C-QoL). METHODS: An analysis of 75 patients with the PSEN1-E280A mutation with mild cognitive impairment and dementia was performed. We used the Quality of Life in Alzheimer Disease (QoL-AD) survey to evaluate QoL as an outcome and evaluated its association with sociodemographic, lifestyle, clinical, and past medical history variables. RESULTS: The largest difference in the median of the QoL-AD score was in those who needed help to eat, those with moderate or severe dementia, those classified as frail or pre-frail, those with moderate social risk, and those with depression. Also, C-QoL was lower than the P-QoL, and the QoL-AD of individuals with severe dementia was lower than for milder forms of the disease. Not needing help to eat, not having a stressful situation in the past 3 months, and the years of education were positively correlated with QoL-AD in the linear model. CONCLUSION: As studies in similar populations with AD, factors with more impact on QoL are those related to loss of functionality and independence. These factors are also associated with variables related to the current literature with the burden of the disease for the caregivers.
