  2. 1. Adult hydrocephalus. Intracranial pressure, B-wave and clinical analysis in patients with noncommunicating and communicating hydrocephalus

    Author : Hannes Stephensen; Göteborgs universitet; []
    Keywords : CSF circulation; hydrocephalus; NPH; communicating hydrocephalus; noncommunicating hydrocephalus; aqueduct stenosis; intracranial pressure; B-waves; transmantle pressure gradient; computerised data acquisition; clinical symptoms.;

    Abstract : Aims of present investigations. Adult patients with clinical and radiological findings consistent with normal pressure hydrocephalus (NPH) were studied. READ MORE

  4. 2. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus

    Author : Petter Holmlund; Anders Eklund; Sara Qvarlander; Jan Malm; Marek Czosnyka; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracranial pressure; posture; cerebrospinal fluid; microgravity; venous collapse; internal jugular vein; fluid dynamics; venous pressure; spaceflight-associated neuro-ocular syndrome; hydrocephalus; mathematical modeling; ultrasound; magnetic resonance imaging;

    Abstract : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. READ MORE

  5. 3. The search for reversibility of Idiopathic normal pressure hydrocephalus : Aspects on intracranial pressure measurments and CSF volume alteration

    Author : Niklas Lenfeldt; Jan Malm; Anders Eklund; Katrine Riklund-Åhlström; John D. Pickard; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Idiopathic normal pressure hydrocephalus; intracranial pressure; subcortical ischemia; neuronal integrity; cortical activation.; infusion test; cerebrospinal fluid dynamics; outflow resistance; compliance; elastance; proton spectroscopy; functional MRI; external lumbar drainage; Neurology; Neurologi;

    Abstract : BACKGROUND: Idiopathic normal pressure hydrocephalus (INPH) is still a syndrome generating more questions than answers. Today, research focuses mainly on two areas: understanding the pathophysiology – especially how the malfunctioning CSF system affects the brain parenchyma – and finding better methods to select patients benefiting from a shunt operation.

  6. 4. Measurements in Idiopathic Normal Pressure Hydrocephalus : Computerized neuropsychological test battery and intracranial pulse waves

    Author : Anders Behrens; Jan Malm; Anders Eklund; Eva Elgh; Niklas Lenfeldt; Marianne Juhler; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hydrocephalus; Normal Pressure; Neuropsychological tests; Neuropsychology; Reliability and validity; Software; Dementia; intracranial pressure; spinal puncture; cerebrospinal fluid pressure; pulse pressure waves; Blood flow velocity; Middle cerebral artery; Pulsatility index; Neurology; neurologi;

    Abstract : Idiopathic Normal Pressure Hydrocephalus (INPH) is a condition affecting gait, cognition and continence. Radiological examination reveals enlarged ventricles of the brain. A shunt that drains CSF from the ventricles to the abdomen often improves the symptoms. READ MORE

  7. 5. Idiopathic Normal Pressure Hydrocephalus : Cerebrospinal Fluid Tap Test and Magnetic Resonance Imaging as Preoperative Prognostic Investigations

    Author : Johan Virhammar; Elna-Marie Larsson; Katarina Laurell; Kristina Giuliana Cesarini; Magnus Tisell; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; normal pressure hydrocephalus; NPH; cerebrospinal fluid disorders; dementia; MRI; CSF tap test; CBF; ASL; Neurology; Neurologi; Neurosurgery; Neurokirurgi; Radiologi; Radiology;

    Abstract : Idiopathic normal pressure hydrocephalus (iNPH) is a condition with dilated cerebral ventricles but intracranial pressure within normal limits. The symptoms of gait impairment, cognitive decline and urinary incontinence develop gradually. Treatment with shunt insertion results in improvement in eight out of ten patients. READ MORE
