Nocturnal positive pressure ventilation improves relationship satisfaction of patients with OSA and their partners.

Objective: Continuous positive airway pressure (CPAP) ventilation is considered the therapeutic standard for obstructed sleep apnea (OSA). Therapy success may also be affected by the patient's bed partner. A questionnaire was developed and tested that measures the attitude of the bed partner towards CPAP therapy and relationship effects.

Diplopia in Parkinson's disease: Indication of a cortical phenotype with cognitive dysfunction?

Background: Visual disturbances are increasingly recognized as common non-motor symptoms in Parkinson's disease (PD). In PD patients, intermittent diplopia has been found to be associated with the presence of visual hallucinations and the Parkinson's psychosis spectrum. Here, we investigated whether diplopia in PD is associated with other non-motor traits and cognitive impairment.

Dysfunctional action control as a specific feature of Parkinson's disease.

Parkinson's disease (PD) is characterised by motor deficits as well as cognitive alterations, particularly concerning frontal lobe control. Here, we were interested in whether executive function is abnormal already early in PD, as well as whether this dysfunction worsens as a part of the dementia in PD. The following groups engaged in tasks addressing action control: PD patients with mild and advanced motor symptoms (aPD) without dementia, PD patients with dementia (PDD), patients with Alzheimer's disease (AD) and healthy subjects (CON).
