2. 1. Intracranial Pressure in Traumatic Brain Injury

   Author : Sima Shahsavari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brain Swelling; Cerebral Autoregulation; Secondary Brain Injury; Traumatic Brain Injury; Cerebral Compliance; Intracranial Dynamics; Intracranial Pressure;

   Abstract : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainely focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity (ICP) has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. READ MORE

4. 2. Human brain function evaluated with rCBF-SPECT : memory and pain related changes and new diagnostic possibilities in Alzheimer’s disease

   Author : Torbjörn Sundström; Katrine Riklund; Rimma Danielsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain imaging; rCBF; SPECT; early diagnosis; brain atlas; HMPAO; Alzheimer´s disease; Whiplash; neuropsychological function; episodic memory; Diagnostic radiology; Diagnostisk radiologi;

   Abstract : The aim of this doctoral thesis was to study the influence of memory, pain, age and education on the regional cerebral blood flow (rCBF), i.e. brain function, in early Alzheimer's disease (AD) and in chronic neck pain patients in comparison to healthy controls and in healthy elderly per se.

5. 3. Pathophysiological Mechanisms and Diagnostic Markers in Alzheimer’s Disease

   Author : Joakim Hertze; Klinisk minnesforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; mild cognitive impairment; white matter lesions; brain reserve; blood-brain barrier; angiogenesis; neuroinflammation; neurogranin; YKL-40; VEGF; IGF; ICAM-1; VCAM-1;

   Abstract : Alzheimer’s disease (AD), the most common cause of dementia, is a growing concern. As the life expectancy increases across the globe, the number of affected people is estimated to reach 100 million by 2050. READ MORE

6. 4. Neurointensive Care of Children with Severe Traumatic Brain Injury : Studies of barbiturate coma treatment, intracranial compliance, pressure autoregulation and optimal cerebral perfusion pressure

   Author : Fartein Velle; Per Enblad; Shruti Agrawal; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Children; Refractory intracranial hypertension; Barbiturate coma; Intracranial compensatory reserve; autoregulation; cerebral microdialysis.; Neurokirurgi; Neurosurgery;

   Abstract : Traumatic brain injury (TBI) is among the most common causes of death and acquired disability during childhood. Management guidelines for pediatric patients are usually extrapolated from adults. Specific pediatric studies are warranted to improve the TBI management in children. READ MORE

7. 5. The aging brain and changes in cognitive performance : Findings from morphometry and quantitative susceptibility mapping of iron

   Author : Ninni Persson; Håkan Fischser; Kristine B. Walhovd; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; brain aging; volumes; ndividual differences; QSM; cognitive aging; iron; episodic memory; fluid-; crystalized abilities; sex differences; gender differences; Psychology; psykologi;

   Abstract : Brain aging is a heterogeneous phenomenon, and this thesis illustrates how the course of aging can vary within individuals over time and between individuals as a function of age, sex, and genetic variability. We used two contrasts from magnetic resonance imaging (MRI), namely spin-lattice T1-weighted imaging, and quantitative susceptibility mapping (QSM) from gradient-echo images, to picture the aging brain, by means of morphometric measures and brain-iron concentrations.
