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

7. The neuropsychology of idiopathic normal pressure hydrocephalus
Sammanfattning : Idiopathic normal pressure hydrocephalus (iNPH) is characterised by an active distension of the cerebral ventricles due to inadequate absorption of cerebrospinal fluid (CSF) into the systemic circulation. The intracranial pressure is within normal limits, the passages between the ventricles and subarachnoid spaces are open, and there is an absence of identifiable antecedents known to reduce CSF absorption.

8. Comorbidity and vascular risk factors associated with idiopathic normal pressure hydrocephalus : the INPH-CRasH Study
Sammanfattning : Idiopathic normal pressure hydrocephalus (INPH) is a dementia treatable by insertion of a cerebrospinal fluid shunt. It has been suggested that INPH has similar pathophysiological mechanisms as cerebrovascular disease, but the vascular risk factor (VRF) profile of INPH patients has not been assessed using a modern epidemiological approach.

9. Cerebrospinal fluid infusion methods : development and validation on patients with idiopathic normal pressure hydrocephalus
Sammanfattning : Cerebrospinal fluid (CSF) infusion tests can be used to estimate the dynamic properties of the CSF system. Idiopathic normal pressure hydrocephalus (INPH) is a syndrome signified by a disturbance to the CSF system, where the cause is unknown and the diagnosis is difficult to determine. LÄS MER
10. Analysis of ICP pulsatility and CSF dynamics : the pulsatility curve and effects of postural changes, with implications for idiopathic normal pressure hydrocephalus
Sammanfattning : The volume defined by the rigid cranium is shared by the brain, blood and cerebrospinal fluid (CSF). With every heartbeat the arterial blood volume briefly increases and venous blood and CSF are forced out of the cranium, leading to pulsatility in CSF flow and intracranial pressure (ICP). LÄS MER
