Aging‐Driven Blood–Brain Barrier Dysfunction and Its Impact on CNS Cancer Susceptibility: A Comprehensive Narrative Review

Aging and Cancer, EarlyView.
Aging weakens the blood–brain barrier (BBB), increasing susceptibility to CNS cancers and complicating treatment. This review examines BBB deterioration, its impact on drug delivery, and potential interventions like targeting neuroinflammation and advanced therapies.

Assessment of Parkinson's Disease Medication State through Automatic Speech Analysis [PDF]

arXiv, 2020
Parkinson's disease (PD) is a progressive degenerative disorder of the central nervous system characterized by motor and non-motor symptoms. As the disease progresses, patients alternate periods in which motor symptoms are mitigated due to medication intake (ON state) and periods with motor complications (OFF state). The time that patients spend in the

Mitochondrial DNA disorders in neuromuscular diseases in diverse populations

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Neuromuscular features are common in mitochondrial DNA (mtDNA) disorders. The genetic architecture of mtDNA disorders in diverse populations is poorly understood. We analysed mtDNA variants from whole‐exome sequencing data in neuromuscular patients from South Africa, Brazil, India, Turkey and Zambia. In 998 individuals, there were two definite

Sleep-related hypermotor epilepsy with genetic diagnosis: description of a case series in a tertiary referral hospital

Journal of Central Nervous System Disease, 2022
Introduction Sleep-related hypermotor epilepsy (SHE) is characterized by asymmetric tonic/dystonic posturing and/or complex hyperkinetic seizures occurring mostly during sleep. Experts agree that SHE should be considered a unique syndrome.

A Multifractal Dynamical Model of Human Gait [PDF]

arXiv, 2005
Summary: Walking is regulated through the motorcontrol system (MCS). The MCS consists of a network of neurons from the central nervous system (CNS) and the intraspinal nervous system (INS), which is capable of producing a syncopated output. The coupling of the latter two systems produces a complex stride interval time series that is characterized by ...

Self-pruning Graph Neural Network for Predicting Inflammatory Disease Activity in Multiple Sclerosis from Brain MR Images [PDF]

arXiv, 2023
Multiple Sclerosis (MS) is a severe neurological disease characterized by inflammatory lesions in the central nervous system. Hence, predicting inflammatory disease activity is crucial for disease assessment and treatment. However, MS lesions can occur throughout the brain and vary in shape, size and total count among patients.

The complement system in central nervous system diseases

Autoimmunity, 2006
The activation of complement system is important factor in inflammatory, neurodegenerative and cerebrovascular diseases. CNS cells are able to synthesize complement components, and myelin and oligodendrocytes (OLG) are known to activate the classical pathway of complement in vitro in the absence of antibodies.

UDP‐glucose dehydrogenase variants cause dystroglycanopathy

Annals of Clinical and Translational Neurology, EarlyView.
Abstract UDP‐glucose dehydrogenase (UGDH) variants have been associated with hypotonia, developmental delay, and epilepsy. We report the first pathologic evidence of dystroglycanopathy in siblings with UGDH variants. Both presented around 6 months with developmental delay and elevated creatinine kinase.

Vanadium dioxide circuits emulate neurological disorders [PDF]

arXiv, 2018
Information in the central nervous system (CNS) is conducted via electrical signals known as action potentials and is encoded in time. Several neurological disorders including depression, Attention Deficit Hyperactivity Disorder (ADHD), originate in faulty brain signaling frequencies.
