  3. 2. 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

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

    Författare :Niklas Lenfeldt; Jan Malm; Anders Eklund; Katrine Riklund-Åhlström; John D. Pickard; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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.
