Background: We investigated levels of the β-amyloid 1-42 (Aβ42), total tau protein (T-tau) and tau phosphorylated at position threonine 181 (P-tau) in cerebrospinal fluid (CSF) of idiopathic normal pressure hydrocephalus (iNPH) patients and tried to find their clinical implications in the evaluation and treatment of iNPH.
Method: Twenty-five possible iNPH patients were prospectively enrolled and their CSF was collected to analyze levels of Aβ42, T-tau and P-tau using ELISA method. Gait disturbance, urinary incontinence, and cognitive impairment were semi-quantified and detailed neuropsychological (NP) test was performed.
Result: Eight iNPH patients were classified into the lower CSF Aβ42 group and 17 patients were classified into the higher CSF Aβ42 group. There was no difference in the iNPH grading score and its improvement after LP between the two groups. The lower CSF Aβ42 group showed more deficits in attention, visuospatial function and verbal memory in the baseline NP test and less improvement in phonemic categorical naming and frontal inhibitory function after LP.
Conclusions: Our study suggested that concomitant AD in iNPH patients might contribute to lumbar puncture or shunt unresponsiveness, especially in the field of cognitive dysfunction.

Background: There is a limited understanding of how older patients perceive the potential of using wearables for remote monitoring (RM) at home. Exploring patients' perspectives prior to the implementation of wearables in healthcare can offer valuable insights into what may enhance the effectiveness and outcomes of RM.
Objectives: The objective of this study was to explore the expectations of older patients with a susceptible chronic illness towards prospective use of the Oura Ring for health monitoring at home.

Objective: Linear radiological measures have low sensitivity to detect changes in ventricular volume in patients with idiopathic normal pressure hydrocephalus (iNPH). Ventricular volumetry is accurate and sensitive in detecting subtle changes in cerebrospinal fluid volumes. The Codman Certas® Plus is an adjustable shunt valve with eight settings and resistant to MRI-induced inadvertent adjustments in vitro.

: Patients with idiopathic normal pressure hydrocephalus (INPH) present similar symptoms as other diseases, such as dementia (AD). However, while dementia is not reversible, INPH dementia can be treated through neurosurgery. This study aims to assess the Rorschach method as a valid tool to identify INPH patients.

Objective: The aims of the study were to investigate differences in cortical mean diffusivity (MD) among idiopathic normal-pressure hydrocephalus (INPH) patients, Alzheimer's disease (AD) patients, and healthy controls, and to analyze mean MD among INPH and AD groups in INPH-specific areas showing distinctive cortical MD changes for distinguishing INPH from AD.
Methods: Forty-two INPH patients, 51 AD patients, and 23 healthy controls were imaged with MRI, including diffusion tensor imaging MR images, for surface-based analysis across the entire brain.
Results: Compared with healthy controls, INPH patients showed a statistically significant reduction in MD in the high convexity of the frontal, parietal, and occipital cortical regions.

Introduction: Normal pressure hydrocephalus (NPH) is a potentially reversible cause of dementia, characterized by a clinical triad of gait disturbance, urinary incontinence, and cognitive decline. Despite suggestive radiologic findings, many patients remain untreated. This study aimed to determine the clinical correlation between radiographic findings of NPH and clinical symptoms.
