PURPOSE: To demonstrate how multichannel visual evoked potentials (VEPs) can provide quantitative measures of visual function in in children with marked cortical anatomy abnormalities. METHODS: Four children with marked brain pathology (2 holoprosencephaly, 2 giant interhemispheric cysts with hydrocephalus) underwent pattern reversal and flash VEP recordings from 16 equally distributed electrodes. Voltage maps of the major VEP components were constructed, and their distributions were compared to the magnetic resonance imaging (MRI) findings...

BACKGROUND: Idiopathic normal pressure hydrocephalus (iNPH) is ventriculomegaly syndrome characterized by dementia, urinary incontinence, and gait disturbance, which is potentially reversible following ventriculoperitoneal shunting (VPS). Magnetic resonance elastography (MRE) is an evolving imaging technology that noninvasively measures tissue viscoelasticity. OBJECTIVE: We studied iNPH patients using MRE prior to shunting, compared them to normal controls, and analyzed associations between MRE findings and clinical features, as a pilot assessment of MRE in iNPH...

OBJECTIVE: To assess the complete vascular risk factor (VRF) profile of idiopathic normal pressure hydrocephalus (INPH) using a large sample of representative patients with INPH and population-based controls to determine the extent to which vascular disease influences INPH pathophysiology. METHODS: All patients with INPH who underwent shunting in Sweden in 2008-2010 were compared to age- and sex-matched population-based controls. Inclusion criteria were age 60-85 years and no dementia...

OBJECTIVE: The diagnosis of shunt malfunction can be challenging since neuroimaging results are not always correlated with clinical outcomes. The purpose of this study was to evaluate the efficacy of a simple, minimally invasive cerebrospinal fluid (CSF) lumbar tapping test that predicts shunt under-drainage in hydrocephalus patients. METHODS: We retrospectively reviewed the clinical and radiological features of 48 patients who underwent routine CSF lumbar tapping after ventriculoperitoneal shunt (VPS) operation using a programmable shunting device...

BACKGROUND AND PURPOSE: Evans index is an estimate of ventricular size used in the diagnosis of idiopathic normal-pressure hydrocephalus (iNPH). Values >0.3 are considered pathological and are required by guidelines for the diagnosis of iNPH. However, there are no previous epidemiological studies on Evans index, and normal values in adults are thus not precisely known. We examined a representative sample to obtain reference values and descriptive data on Evans index. METHODS: A population-based sample (n = 1235) of men and women aged ≥70 years was examined...

OBJECTIVES: Normal pressure hydrocephalus (NPH) is a treatable neurological disorder that appears in older adults, lacks specific diagnostic criteria, and resembles symptoms seen in Alzheimer's disease (AD). Presently, differentiating NPH from AD in the early stages of symptom presentation remains difficult. This study established whether olfactory testing may be useful in this regard. In addition, we determined whether olfactory function of NPH patients differed before and after extended lumbar drainage (ELD), as well as six months after surgical implantation of a ventriculoperitoneal (VP) shunt...

Apathy represents the most common behavioral disturbance in patients with suspicion of idiopathic normal pressure hydrocephalus (iNPH) and has a major impact on quality of life. However, its impact on gait -the hallmark motor disturbance of iNPH - has never been studied yet. This study aims to evaluate the impact of apathy on higher level of gait control in patients with suspicion of iNPH. Stride time variability (STV), a marker of higher level of gait control, was quantified during usual walking (single task) and during walking while performing simultaneously cognitive tasks (dual task) of counting and verbal fluency...

To clarify the pathogenesis of two different types of adult-onset normal-pressure hydrocephalus (NPH), we investigated cerebrospinal fluid distribution on the high-field three-dimensional MRI. The subarachnoid spaces in secondary NPH were smaller than those in the controls, whereas those in idiopathic NPH were of similar size to the controls. In idiopathic NPH, however, the basal cistern and Sylvian fissure were enlarged in concurrence with ventricular enlargement towards the z-direction, but the convexity subarachnoid space was severely diminished...

PURPOSE: Small meningiomas causing hydrocephalus without obstruction of the ventricular system are rare. Herein, we report a case of small clinoidal meningioma with communicating hydrocephalus, which resolved after tumor removal. CASE PRESENTATION: A 70-year-old woman presented with a 1-month history of memory disturbance followed by gait disturbance. MR images revealed a right clinoidal meningioma, 2 cm in diameter, and dilatation of the ventricles suggesting communicating hydrocephalus...

We report the case of a 72-year-old patient presenting in our ICU with persistent postoperative coma in a context of recent unexplored neurological dysfunction. Detailed medical history taking from the patient's family revealed he recently suffered from gait instability, urinary incontinence, and slight cognitive impairment. These constituted the clinical triad of normal pressure hydrocephalus syndrome. The presence of normal cerebrospinal fluid (CSF) pressure and distinctive radiological findings confirmed the diagnosis of normal pressure hydrocephalus or Hakims-Adams syndrome...

A 61-year-old woman presented with a 10-month history of gait disturbance and a 7-month history of urinary incontinence. The Hasegawa dementia scale-revised score indicated cognitive impairment. Brain magnetic resonance imaging (MRI) indicated hydrocephalus with disproportionately enlarged subarachnoid space. This is usually considered a characteristic finding in idiopathic normal pressure hydrocephalus (iNPH). Ventriculo-peritoneal shunting improved the patient's symptoms. Neurosarcoidosis was suspected as a cause of the hydrocephalus because of the abnormalities in the cerebrospinal fluid and the abnormal enhancement of the cauda equina, the leptomeninges of the brainstem, and the spinal cord, as seen on MRI with gadolinium enhancement...

BACKGROUND: Choroid plexus papillomas (CPPs) are rare benign intracranial tumors. We report a rare case of CPP manifesting with typical symptoms of normal-pressure hydrocephalus rather than obstructive hydrocephalus. CASE DESCRIPTION: A 45-year-old woman presented with a 6-year history of headache and typical symptoms of normal-pressure hydrocephalus, including gait disturbance, urinary incontinence, and cognitive dysfunction, in addition to the more common symptoms of CPP, such as lower cranial nerve dysfunctions and ataxia...

BACKGROUND: Patients presenting with the classical idiopathic normal pressure hydrocephalus (iNPH) triad often show additional parkinsonian spectrum signs. Accurate differential diagnosis strongly influences the long-term outcome of cerebrospinal fluid (CSF) shunting. OBJECTIVE: The aim of this study was to find potential CSF microRNA (miRNA) biomarkers for NPH mimics with parkinsonian syndromes that can reliably distinguish them from iNPH patients. METHODS: Two cohorts of 81 patients (cohort 1, n = 55; cohort 2, n = 26) with possible iNPH who were treated in two centers between January 2011 and May 2014 were studied...

BACKGROUND: It remains unclear how intracranial pressure (ICP) measures are associated with brain biopsies and radiological markers. Here, we aim to investigate associations between ICP and radiological findings, brain biopsies, and shunt surgery outcome in patients with suspected idiopathic normal pressure hydrocephalus (iNPH). METHOD: In this study, we retrospectively analyzed data from 73 patients admitted with suspected iNPH to Kuopio University Hospital. Of these patients, 71% underwent shunt surgery...

BACKGROUND: To improve the diagnostic performance of the cerebrospinal fluid (CSF) tap test (TT), early and delayed assessments of gait were performed after the removal of 30 ml of CSF in patients with probable idiopathic normal pressure hydrocephalus. Assessments of gait included the 3-m timed up and go test (TUG), and the 10-m walk in time (10Ti) and in step (10St) tests. METHODS: Quantitative data for the TUG, the 10Ti, and the 10St were obtained before CSF removal and on days 1 and 4 after removal of 30 ml CSF...

The cerebrospinal fluid tap test (CSFTT) is widely used to diagnose idiopathic normal pressure hydrocephalus (iNPH) and predict the therapeutic effectiveness of shunting. However, the ability to walk cannot be quantified for patients who are unable to walk. Therefore, we examined whether the iNPH diagnostic aid is possible using dynamometry, even for patients who are unable to walk. In this study, 45 patients underwent grip strength assessment, quadriceps strength assessment, 10-m walk test, and 3-m Timed Up and Go test before and after CSFTT...

Little is known about genetic risk factors for idiopathic normal pressure hydrocephalus (iNPH). We examined whether a copy number loss in intron 2 of the SFMBT1 gene could be a genetic risk for shunt-responsive, definite iNPH. Quantitative and digital PCR analyses revealed that 26.0% of shunt-responsive definite iNPH patients (n = 50) had such a genetic change, as compared with 4.2% of the healthy elderly (n = 191) (OR = 7.94, 95%CI: 2.82-23.79, p = 1.8 x 10-5) and 6.3% of patients with Parkinson's disease (n = 32) (OR = 5...
