This study will determine the level of association between the quantitative estimates of brain uptake of [18F]flutemetamol and the quantitative immunohistochemical estimates of amyloid levels in biopsy samples previously obtained during shunt placement in patients who have normal pressure hydrocephalus (NPH).

Normal Pressure Hydrocephalus

To determine the level of association between the quantitative estimates of brain uptake of [18F]flutemetamol and the quantitative immunohistochemical and histochemistry estimates of amylo...
The overall aim of the registry is to develop a longitudinal, observational database that is focused on adult patients with Normal Pressure Hydrocephalus (NPH) that can be used as a source...
This study aims to provide class 1 evidence supporting or refuting the existence of normal pressure hydrocephalus.
Hydrocephalus (secondary or idiopathic) is a condition characterized by dilatation of the lateral and third ventricles, and often associated with increased intracranial pressure (ICP). We ...
The purpose of this study is to test and compare the efficacy of Endoscopic Third Ventriculostomy with shunting of Cerebrospinal fluid (CSF)for treatment for patients of Normal pressure Hy...
Normal pressure hydrocephalus (NPH), described by Hakim and Adams in 1965, is characterized by gait apraxia, urinary incontinence, and dementia. It is associated with normal cerebrospinal fluid (CSF) ...
Recent Normal Pressure Hydrocephalus (NPH) practice guidelines describe a serious adverse event (SAE) rate following surgery of 11%.
This cross-sectional study aims to compare gait changes after CSF tap test between normal pressure hydrocephalus patients with and without brain comorbidities (respectively NPH+ and NPH); and then ide...
An accurate intracranial pressure (ICP) measurement is vital for patients with hydrocephalus. ICP is generally measured by lumbar puncture opening pressure, which is invasive and has potential adverse...
This study aimed to confirm whether cerebrospinal fluid (CSF) shunting for idiopathic normal-pressure hydrocephalus (iNPH) improves postural instability, and to investigate the relationship between po...
A form of compensated hydrocephalus characterized clinically by a slowly progressive gait disorder (see GAIT DISORDERS, NEUROLOGIC), progressive intellectual decline, and URINARY INCONTINENCE. Spinal fluid pressure tends to be in the high normal range. This condition may result from processes which interfere with the absorption of CSF including SUBARACHNOID HEMORRHAGE, chronic MENINGITIS, and other conditions. (From Adams et al., Principles of Neurology, 6th ed, pp631-3)
Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.
The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).
A form of GLAUCOMA in which chronic optic nerve damage and loss of vision normally attributable to buildup of intraocular pressure occurs despite prevailing conditions of normal intraocular pressure.
Increased pressure within the cranial vault. This may result from several conditions, including HYDROCEPHALUS; BRAIN EDEMA; intracranial masses; severe systemic HYPERTENSION; PSEUDOTUMOR CEREBRI; and other disorders.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
Health care (or healthcare) is the diagnosis, treatment, and prevention of disease, illness, injury, and other physical and mental impairments in humans. Health care is delivered by practitioners in medicine, chiropractic, dentistry, nursing, pharmacy, a...
