OBJECTIVES This study seeks to validate the use of activity monitors to detect and record gait abnormalities, potentially identifying patients with idiopathic normal pressure hydrocephalus (iNPH) prior to the onset of cognitive or urinary symptoms. METHODS This study compared the step counts of four common activity monitors (Omron Step Counter HJ-113, New Lifestyles 2000, Nike Fuelband, and F...

Although new MR imaging techniques can provide high-resolution information on CSF dynamics and are not associated with ionizing radiation, SPECT/CT cisternography is a valuable alternative for those with contraindications to MR imaging. SPECT/CT cisternography combines functional and anatomic imaging to provide accurate and detailed information on CSF distribution to be used in conjunction with...

Gliomatosis cerebri (GC) is a rare astrocytic tumor that typically affects multiple lobes of the brain. Due to its insidious nature and atypical symptom presentation, diagnosis is often made late in the course of disease process. To date, no definitive treatment guidelines have been established, and due to its infiltrating pattern, neurosurgical resection of the lesion is generally not feasible...

BACKGROUND AND PURPOSE There is limited evidence to support the use of high-volume lumbar taps over lower-volume taps in the diagnosis of normal pressure hydrocephalus. The purpose of this study is to detect whether the volume of CSF removed from patients undergoing high-volume diagnostic lumbar tap test for normal pressure hydrocephalus is significantly associated with post-lumbar tap gait per...

Guga Kala, male child, 1 year old, 6th June 1890. Admitted with a gigantic enlargement of the head clue to hydrocephalus. At the time of birth the head was said to be of natural size, and preserved the same natural proportion till four weeks old. It was then noticed to grow in size gradually, and has attained the present enormous bulk. It is so very heavy and disproportionate to the rest of the...

We report a case of a 46-year-old man presenting with a progressive cognitive decline, ataxic gait, urinary incontinence for 4 months and neuroimaging consistent with normal pressure hydrocephalus. The atypical presentation of a progressively worsening dysphasia and a right hemiparesis dismissed as a vascular event 1 month earlier associated with normal pressure hydrocephalus prompted further i...

We aimed to determine whether presence of AD neuropathology predicted cognitive, gait and balance measures in patients with idiopathic normal pressure hydrocephalus (iNPH) after shunt surgery. This is a prospective study of gait and balance measured by Timed Up and Go (TUG) and Tinetti tests, and cognitive function measured by Mini Mental Status Exam (MMSE), before and after shunt surgery in pa...

In this study, we derive new expressions for the probability of outage where a mobile unit receives a Nakagami desired signal and multiple, cochannel, independent Nakagami interferers. Unlike some previous results, the expressions are usable when the Nakagami fading parameter, m , is not necessarily an integer. An exact formula is also derived for the outage probability when the desired signal ...

BACKGROUND AND PURPOSE The PVI(CC) of the craniospinal compartment defines the shape of the pressure-volume curve and determines the damping of cyclic arterial pulsations. Despite no reports of direct measurements of the PVI(CC) among healthy elderly, it is believed that a change away from adequate accommodation of cardiac-related pulsations may be a pathophysiologic mechanism seen in neurodege...
