Special Issue Information

Dear Colleagues,

This topic evolved during studies of locus coeruleus—the major hub of norepinephrine projection to various brain regions, including the nigrostriatal system—which is strongly affected in Parkinson’s disease. This Special Issue will focus on elucidation of the broad spectrum of underlying mechanisms of motor and neuropsychiatric symptoms of Parkinson’s disease. The scope may also include recently developed treatment approaches for presented malfunctions in Parkinson’s disease, for example, the use of imaging techniques, e.g., X-ray diffraction; quantitative susceptibility mapping (QSM); X-ray fluorescence microscopy (XFM); cell type-specific techniques, e.g., optogenetics; deep brain stimulation (DBS); stem cell-based neural organoid culture; protein interaction networks; single-cell sequencing; and others. We seek papers which deliver novel insights into the mechanisms of Parkinson’s disease which contributing to the broad and versatile spectrum of observed motor and neuropsychiatric symptoms, such as involved pathways, neuronal circuits, regional cell death, neurotransmitter imbalance as well as aberrations in proteins and their interactions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Brain Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In older individuals, hand fine motor skill disability is associated with cognitive levels. Similarly, patients with moderate-to-advanced Parkinson’s disease (PD) often have cognitive dysfunction. Here, we investigated the association between hand fine motor skill and cognitive dysfunction in patients with moderate-to-advanced PD. Moderate and advanced PD patients with and without dementia were identified from the Taiwan Data Bank of Persons with Disability. Hand fine motor capacities, namely pen holding, buttoning, and knotting, were assessed with the World Health Organization Disability Assessment Schedule 2.0. Statistical analyses were performed on Statistical Analysis System (SAS) and a p value of <0.05 was considered significant. In total, 3440 patients with PD were enrolled, of which 612 had dementia, exhibiting significant disability in all three tasks. After adjustments for age, sex, and PD severity, pen holding and knotting were significantly associated with PD dementia. The presence of any disability in either task was not only sensitive to the presence of dementia but also associated with cognitive disability in moderate and advanced PD patients without dementia. In conclusion, hand fine motor skill disability was associated with cognitive disability in patients with moderate-to-advanced PD. These simple hand fine motor skills may thus be applicable in screening tests for the early identification of cognitive dysfunction in patients with moderate-to-advanced PD. Full article
