Active and non-active progression independent of relapse activity within the first 20 years of relapsing multiple sclerosis.
Progression independent of relapse activity (PIRA) has been described since the early stage of relapsing multiple sclerosis (RMS). However, little is known about the relation between PIRA and inflammatory activity that is particularly important at this stage of the disease. ⋯ This study evidenced that inflammatory activity increases the risk of PIRA in early RMS, arguing that a significant part of PIRA is accessible to treatment targeting inflammation in these patients.

Contribution of basal ganglia activity to REM sleep disorder in Parkinson's disease.
Rapid eye movement (REM) sleep behaviour disorder (RBD) is one of the most common sleep problems and represents a key prodromal marker in Parkinson's disease (PD). It remains unclear whether and how basal ganglia nuclei, structures that are directly involved in the pathology of PD, are implicated in the occurrence of RBD. ⋯ These findings support that basal ganglia activities are associated with if not directly contribute to the occurrence of RBD in PD. Our study expands the understanding of the role basal ganglia played in RBD and may foster improved therapies for RBD by interrupting the basal ganglia-muscular communication during REM sleep in PD.

Neuropsychiatric symptoms in cognitive decline and Alzheimer's disease: biomarker discovery using plasma proteomics.
Neuropsychiatric symptoms (NPS) are common in older people with cognitive impairment and Alzheimer's disease (AD). No biomarkers to detect the related pathology or predict the clinical evolution of NPS are available yet. This study aimed to identify plasma proteins that may serve as biomarkers for NPS and NPS-related clinical disease progression. ⋯ Plasma proteins are associated with NPS and improve prediction of future NPS.
