Cognitive decline and dementia are frequent in patients with Parkinson's disease (PD). The evidence for nonpharmacological therapies in Alzheimer's disease and other dementias has been studied systematically, but the evidence is unclear for their efficacy in cognition and dementia in PD. An international collaboration produced a comprehensive, systematic(More)
Cognitive training has been shown to be effective in improving cognitive functions in patients with Mild Cognitive Impairment (MCI). However, data on factors that may influence training gains including sociodemographic variables such as sex or age is rare. In this study, the impact of sex on cognitive training effects was examined in N = 32 age- and(More)
INTRODUCTION Cognitive impairment is a common and disabling non-motor symptom in Parkinson's disease (PD). The apolipoprotein E (APOE) allele ε4 is a known risk factor for Alzheimer's disease and has also been suggested to be a risk factor for dementia in PD and even a predictor of impairment in certain cognitive domains. METHODS A total of 447 PD(More)
INTRODUCTION Cognitive training (CT) has been reported to improve cognition in older adults. Its combination with protective factors such as physical activity (CPT) has rarely been studied, but it has been suggested that CPT might show stronger effects than pure CT. MATERIALS AND METHODS Healthy older adults (aged 50-85 years) were trained with CPT (n=15)(More)
BACKGROUND In Parkinson's Disease (PD), cognitive dysfunctions which can reduce patients' quality of life occur frequently. Data on non-pharmacological intervention effects on cognitive functions in patients with PD are rare. The aim of this study was to examine the effects of different cognitive group trainings (structured vs. unstructured) on cognition,(More)
