Hydrocephalus is one of the most common neurological diseases, characterized by abnormal excessive accumulation of cerebrospinal fluid (CSF) in the ventricular system. Its pathophysiological mechanism is believed to be related to the imbalance of CSF circulation and homeostasis. As the main source of CSF secretion, the choroid plexus is closely related to hydrocephalus.

Introduction: Focal impaired awareness seizures are a common neurological disorder characterized by abnormal electrical activity in a specific brain region, resulting in impaired consciousness and neurological symptoms. Treatment options for patients may include antiepileptic medications, lifestyle modifications, or, in some cases, surgical intervention aimed at resecting the area of the brain responsible for seizure generation. Shunt malfunction can lead to seizures in cases of hydrocephalus; however, seizures triggered by stimulation of a specific brain area by the shunt catheter post-placement have not been reported.

Background: Hydrocephalus is a condition characterized by the accumulation of cerebrospinal fluid (CSF) in the ventricular system due to various causes, including excessive CSF production, impaired circulation, or absorption dysfunction. This condition is often accompanied by ventricular enlargement, compression of brain parenchyma, and increased intracranial pressure. Ventriculoperitoneal (VP) shunting is the first-line treatment for hydrocephalus; however, when the peritoneal catheter becomes obstructed due to encapsulation, the procedure may need to be converted to a ventriculoatrial (VA) shunt, which serves as a second-line treatment.

Background: Caudal brainstem dysfunction associated with Chiari malformation type II (CM-II) is an important source of morbidity and mortality in neonates with myelomeningocele (MMC).
Observations: Prenatal MMC repair has been shown to improve or even completely reverse the extent of hindbrain herniation (HH) associated with CM-II as well as reduce the incidence of hydrocephalus requiring CSF diversion, possibly leading to a reduction in CM-II-related symptoms in these children. Urgent CSF diversion and potential CM-II decompression surgery are typically the preferred treatments for infants demonstrating caudal brainstem dysfunction, although contemporary reports have described a decreased need for both CSF diversionary surgery and CM-II decompression following prenatal MMC repair.

Gait abnormalities are common in the older population owing to aging- and disease-related changes in physical and neurological functions. Differentiating the causes of gait abnormalities is challenging because various abnormal gaits share a similar pattern in older patients. Herein, we propose a deep neural network (DNN) model to classify disease-specific gait patterns in older adults using commercialized instrumented insoles.
