Background: Cognitive screening is crucial in Parkinson's disease (PD). However, there is still a lack of short tools in French. In this study, we aimed to compare the Parkinson Neuropsychometric Dementia Assessment (PANDA) with the Mini Mental Parkinson (MMP), the Mini Mental State Examination (MMSE) and the Clock Test in French-speaking patients. We also aimed to propose cut-off scores for cognitive impairment and dementia for the French language version of the PANDA.
Method: Fifty-one patients with PD took the PANDA, the MMSE, the MMP, and the Clock Test. They also underwent extensive neuropsychological testing by a neuropsychologist who was blinded to the above-mentioned screening test results. Patients were classified as either having normal cognition (n=15), mild cognitive impairment (n=20) or dementia (n=16).
Results: When compared with the three other screening tools, the PANDA exhibited the highest area under the curve (AUC) for both cognitive disorders and dementia. Using the cut-off scores proposed for the German version, the PANDA had 94% specificity and 100% sensitivity for dementia and 100% and 72%, respectively for cognitive disorders.
Conclusions: In our study, the PANDA exhibited a higher discriminative power than the three other tests in detecting cognitive disorders and dementia. In PD patients, the PANDA should thus be considered for the detection of cognitive impairment in routine clinical practice.

Background: Radiotherapy as a complement or an alternative to neurosurgery has a central role in the treatment of skull base grade I-II meningiomas. Radiotherapy techniques have improved considerably over the last two decades, becoming more effective and sparing more and more the healthy tissue surrounding the tumour. Currently, hypo-fractionated stereotactic radiotherapy (SRT) for small tumours and normo-fractionated intensity-modulated radiotherapy (IMRT) or proton-therapy (PT) for larger tumours are the most widely used techniques.

Many diseases and disorders of the nervous system suffer from a lack of adequate therapeutics to halt or slow disease progression, and to this day, no cure exists for any of the fatal neurodegenerative diseases. In part this is due to the incredible diversity of cell types that comprise the brain, knowledge gaps in understanding basic mechanisms of disease, as well as a lack of reliable strategies for delivering new therapeutic modalities to affected areas. With the advent of single cell genomics, it is now possible to interrogate the molecular characteristics of diverse cell populations and their alterations in diseased states.

Alzheimer's disease (AD) is a common neurodegenerative disease characterized by progressive memory loss and cognitive decline. The processes underlying the pathophysiology of AD are still not fully understood despite a great deal of research. Since mitochondrial dysfunction affects cellular energy metabolism, oxidative stress, and neuronal survival, it is becoming increasingly clear that it plays a major role in the development of AD.

Early detection of cognitive dysfunction in patients with type 2 diabetes mellitus (T2DM) is important for preventive measures due to the lack of effective treatments. The purpose of this study is to investigate the relationship between enlarged perivascular space in the hippocampus (H-EPVS) and cognitive performance in patients with T2DM, and to determine whether it can serve as an imaging marker for cognitive dysfunction. 66 T2DM patients with cognitive impairment (T2DM-CI) and 71 T2DM patients with normal cognitive function (T2DM-NC) underwent cranial MRI scans and comprehensive neuropsychological assessments.

Overactive bladder (OAB) is a prevalent condition among older adults and may be linked to cognitive health. This study explored a relationship between OAB and cognitive health among adults aged 60 ≥ years in the United States, using NHANES 2011-2014. A cross-sectional analysis was conducted using a nationally representative sample of 2,324 (45.
