Sleep disorders are common in Parkinson's disease (PD) and seem to be strongly associated with depression. It has been suggested that sleep disorders as well as depression are caused by a disturbed circadian rhythm. Indeed, PD patients are prone to misalignment of their circadian rhythm due to various factors, and many patients with PD display a phase(More)
INTRODUCTION Anxiety disorders are highly prevalent in patients with Parkinson's disease (PD) and have a major impact on wellbeing. They nevertheless receive limited scientific attention. This study aimed to establish the symptom dimensions of anxiety in PD, and their relationship with depression, autonomic failure and motor symptoms. METHODS In this(More)
BACKGROUND Up to 50% of all patients with Parkinson's disease (PD) suffer from anxiety symptoms, a much higher percentage than in the general population. This suggests that PD associated pathological alterations partly underlie these symptoms, although empirical evidence is limited. METHODS Here we investigated the association between anxiety symptoms(More)
Depression and impulse control disorders (ICD) are two common neuropsychiatric features in Parkinson's disease (PD). Studies have revealed that both phenomena are associated with aberrations in ventral striatal dopamine signaling and concomitant dysfunction of the reward-related (limbic) cortico-striatal-thalamocortical (CSTC) circuit. Depression in PD(More)
An atypical presentation of delirium increases the risk of misdiagnosis and undertreatment. Three cases are presented in this article. A 65-year-old woman, admitted for malnutrition, has significant mood-related symptoms that resemble depression. A 50-year-old male, admitted with an abscess, necrotizing fasciitis and sepsis, appears to be suicidal. A(More)
Chapter Two – A smaller amygdala is associated with anxiety in Parkinson's disease – a combined FreeSurfer-Voxel-based-morphometry study under review Two A smaller amygdala is associated with anxiety in Parkinson's disease – a combined FreeSurfer-Voxel-based-morphometry study Abstract Up to 50 percent of all Parkinson's disease (PD) patients develop(More)
BACKGROUND A disturbed circadian rhythm seems to be a causal factor in the occurrence of depressive disorders in patients with Parkinson's disease (PD). The circadian rhythm can be restored with light. Therefore, Bright Light Therapy (BLT) might be a new treatment option for depression in PD patients. METHODS/DESIGN In this double-blind controlled trial,(More)
BACKGROUND Improvements in quality of life (QOL) obtained by weight loss have mainly been reported after bariatric surgery. QOL has not been investigated in surgical patients first losing weight by nonsurgical means followed by a surgical intervention and never simultaneously by two QOL-a generic and a disease-specific-questionnaires. METHODS Prospective(More)
AIM Anxiety has a negative impact on daily functioning and quality of life in patients with Parkinson's disease (PD). This study aims at assessing which sociodemographic and clinical characteristics predict the course of anxiety in early PD. METHODS The participants of this two-year prospective cohort study were recently diagnosed PD patients not(More)
BACKGROUND The wearing-off phenomenon in patients with Parkinson's disease (PD) is a complication of prolonged levodopa usage. During this phenomenon, motor symptoms such as rigidity and freezing re-emerge. This is often accompanied by non-motor symptoms, including anxiety, the so-called wearing-off related anxiety (WRA). Current treatment options are(More)
