Researchers at Wenzhou Medical University in China recently reviewed literature related to iron levels in the brains of patients with Parkinson’s disease (PD) and confirmed elevated levels in several regions of the brain. The review paper, “Meta-analysis of brain iron levels of Parkinson’s disease patients determined by postmortem and…

Genetic mutations associated with Parkinson’s disease appear to alter the processes of neuronal death, University College London (UCL) researchers suggest in a study titled “The Parkinson’s disease-linked proteins Fbxo7 and Parkin interact to mediate mitophagy,” published in Nature Neuroscience. Neurons are dependent on the integrity of mitochondria, the energy…

York University researchers have reported a new method of visual profiling that could help in the early detection of Parkinson’s disease. The study, titled “Classification of Parkinson’s Disease Genotypes in Drosophila Using Spatiotemporal Profiling of Vision,” was published in Scientific Reports. Parkinson’s is a disorder that affects motor…

A recent published paper in Alzheimer’s & Dementia: the journal of the Alzheimer’s Association entitled “Improving the Clinical Detection of Lewy Body Dementia with the Lewy Body Composite Risk Score,” reports a new quick test to determine signs and symptoms of Lewy Body dementia…

A team of researchers localized the specific types of neurons involved in movement, work that might be of relevance to understand neurodegenerative diseases like Parkinson’s and Huntington’s. The study, entitled “Cell-Type-Specific Sensorimotor Processing in Striatal Projection Neurons during Goal-Directed Behavior,” was published in Neuron. Neurodegeneration occurs when…

In a newly published paper in the Cerebral Cortex journal entitled “Dopamine D1 Receptor-Mediated Transmission Maintains Information Flow Through the Cortico-Striato-Entopeduncular Direct Pathway to Release Movements,” researchers from Japan reported that lack of dopamine transmission through D1 receptors is linked to slower movements…

In a recently published paper in Tissue Engineering Part C: Methods entitled “3D Neural Spheroid Culture: An In Vitro Model for Cortical Studies“, researchers from Brown University reported a method to produce spheres like mini-brains containing central nervous system tissue. These mini-brains have no…

In a recently published paper in ACS Applied Materials and Interfaces journal entitled “Support of Neuronal Growth Over Glial Growth and Guidance of Optic Nerve Axons by Vertical Nanowire Arrays“, researchers from Lund University in Sweden developed a strategy to grow neuronal cells on…

In a recent study published in PLOS One, entitled “Temporal Lobe and Frontal-Subcortical Dissociations in Non-Demented Parkinson’s Disease with Verbal Memory Impairment“, scientists from the University of Florida examined the association between Parkinson’s disease in non-dementia patients and verbal memory impairment. They found that about…
