Exploring Theory of Mind abilities in patients with probable idiopathic normal pressure hydrocephalus

Journal of Neuropsychology, EarlyView.
Abstract This study investigated Theory of Mind (ToM) deficits in patients with suspected idiopathic normal pressure hydrocephalus (iNPH), a condition affecting motor, cognitive and autonomic functions. Given the overlap between ToM‐related neural networks and those affected in iNPH, we examined whether ToM impairments are a feature of the disease ...

Circadian rhythm in idiopathic normal pressure hydrocephalus [PDF]

Clinical Neurology and Neurosurgery, 2015
The pathogenesis of idiopathic normal pressure hydrocephalus (iNPH) takes place in structures close to the cerebral ventricular system. Suprachiasmatic nucleus (SCN), situated close to the third ventricle, is involved in circadian rhythm. Diurnal disturbances are well-known in demented patients.

Decrease of excessive daytime sleepiness after shunt treatment for normal pressure hydrocephalus

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleepiness and apathy are often reported in patients with normal pressure hydrocephalus. However, research on outcomes after shunt surgery has mainly focused on the classical triad symptoms, that is, gait, cognition, and bladder dysfunction. This study aimed to describe the effects of shunt treatment on excessive daytime sleepiness and whether ...

Neurosyphilis Concurrently Presenting With Limbic Encephalitis and Normal Pressure Hydrocephalus: A Case Report

Neuropsychopharmacology Reports, Volume 46, Issue 4, December 2026.
We report a case of neurosyphilis characterized by early‐onset dementia, limbic encephalitis, and normal pressure hydrocephalus. Psychiatrists should be aware of the possibility of neurosyphilis in such cases. ABSTRACT Background Neurosyphilis may present with a variety of clinical symptoms and neuroimaging findings and is thus likely to be overlooked.

High‐Resolution IVIM MRI Characterizes Diffusion–Perfusion Properties of the Parasagittal Dura

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
Parasagittal dura demonstrates intermediate diffusion and elevated perfusion‐related IVIM metrics compared with brain parenchyma, reflecting its unique microfluidic environment at the CSF–dura interface. IVIM imaging of the parasagittal dura provides a rapid, noncontrast MRI approach to assess dural fluid transport and may offer a potential imaging ...

Glymphatic System Dysfunction and its Associated Factors in Wilson's Disease: A DTI–ALPS Study

Brain and Behavior, Volume 16, Issue 10, October 2026.
Glymphatic function, assessed by DTI‐ALPS index, was impaired in neurological Wilson's disease compared with hepatic phenotype and controls. Age, AST, and UWDRS‐I score independently predicted dysfunction, linking neurodegeneration, liver injury, and altered glymphatic activity. ABSTRACT Background Wilson's disease (WD) is a genetic disorder of copper (

Are brain displacements and pressures within the parenchyma induced by surface pressure differences? A computational modelling study.

PLoS ONE, 2023
The intracranial pressure is implicated in many homeostatic processes in the brain and is a fundamental parameter in several diseases such as e.g. idiopathic normal pressure hydrocephalus.

Extensive Cerebral Venous Sinus Thrombosis With Obstructive Hydrocephalus in a Young Female With Underlying Essential Thrombocythemia: A Case Report

Clinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT Persistent symptoms suggestive of idiopathic intracranial hypertension despite standard therapy should prompt urgent neuroimaging to exclude cerebral venous sinus thrombosis. When CVST is confirmed without an obvious provoking factor, evaluation for underlying myeloproliferative neoplasms, including JAK2‐positive essential thrombocythemia, is ...
