  1. 1. Population-based studies of higher-level gait disorders and hydrocephalus : focused on brain ventricular morphometry and patient outcomes following shunt surgery

    Författare :Jenny Larsson; Jan Malm; Anders Eklund; Hanna Israelsson Larsen; Lars-Owe D. Koskinen; Uwe Kehler; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Higher-level gait disorder; Idiopathic Normal Pressure Hydrocephalus; Ventriculomegaly; Falls; Fear of Falling; Self-efficacy; Depression; Quality of life; Adverse events; Headache; Epilepsy; Abdominal pain;

    Sammanfattning : Background: To study gait is of great importance for the health of the aging population. Higher-level gait disorders (HLGD) are characterized by a slow, symmetrical, unsteady gait. Its cause is most often unknown. HLGD in combination with ventriculomegaly (i. LÄS MER

  3. 2. Wearable systems and sensors for the assessment of motor control : Development and validation of methods for clinical assessment of idiopathic normal pressure hydrocephalus

    Författare :Tomas Bäcklund; Nina Sundström; Anders Eklund; Jan Malm; Kaj Lindecrantz; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gait; step-width; heel-heigt; balance; trunk sway; idiopathic normal pressure hydrocephalus; IMU; Inter-rater reliability; kinematics; medical informatics; medicinsk informatik;

    Sammanfattning : Human gait and balance are controlled by automatic processes in the central nervous system, and in sensory and proprioceptive systems. If a disturbance occurs in any of these complex structures, it may lead to balance and gait problems. LÄS MER

  4. 3. 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

  5. 4. Radiological and Clinical Changes in Idiopathic Normal Pressure Hydrocephalus: MRI, Vascular factors and Clinical Symptoms as Markers of Pathophysiology and Prognosis

    Författare :Simon Agerskov; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; idiopathic normal pressure hydrocephalus; MRI; biomarkers; prediction;

    Sammanfattning : Idiopathic normal pressure hydrocephalus (iNPH) is a treatable, neurological disorder affecting the elderly population causing gait, balance, cognitive and micturition impairments. Treatment results in a clinical improvement in up to 80% of patients. LÄS MER

  7. 5. Brain imaging in preterm infants at term equivalent age : value and comparison of MRI and ultrasound

    Författare :Sandra Horsch; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cranial ultrasound (cUS) and magnetic resonance imaging (MRI) are the two most commonly used brain imaging techniques in preterm infants. cUS can be performed at the bedside and detects all major brain abnormalities (haemorrhages, infarctions, cysts, dilatation of the lateral ventricles) that are associated with severe neurodevelopmental disability.
