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

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

    Sammanfattning : Aims of present investigations. Adult patients with clinical and radiological findings consistent with normal pressure hydrocephalus (NPH) were studied. LÄS MER

  3. 2. Hydrocephalus in children. Epidemiology and outcome

    Författare :Eva-Karin Persson; Göteborgs universitet; []
    Nyckelord :Prevalence; Epidemiology; Hydrocephalus; MMC; Treatment; Outcome;

    Sammanfattning : Aims: To analyse trends in the live-birth prevalence of infantile hydrocephalus and hydrocephalus associated with myelomeningocele (MMC) during the period 1989-2002 and to study the outcome in terms of learning disability, cerebral palsy, epilepsy and visual deficits. Another objective was to explore motor function and disability profiles in various aetiological and gestational-age subgroups and to see whether treatment complications and neuroradiological findings correlate with outcome.

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

    Författare :Anders Behrens; Jan Malm; Anders Eklund; Eva Elgh; Niklas Lenfeldt; Marianne Juhler; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Petter Holmlund; Anders Eklund; Sara Qvarlander; Jan Malm; Marek Czosnyka; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Johan Virhammar; Elna-Marie Larsson; Katarina Laurell; Kristina Giuliana Cesarini; Magnus Tisell; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
