1. 1. Cerebral white matter changes in patients with cognitive impairment - clinical and pathophysiological aspects

   Författare :Michael Jonsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; white matter changes; vascular factors; cognitive impairment; neuropsychiatric symptoms; cerebrospinal fluid biomarkers; demyelination; axonal degeneration;

   Sammanfattning : Cerebral white matter changes (WMC), detected with computed tomography (CT) or magnetic resonance imaging (MRI), represent a common condition in elderly people. However, the prognostic, symptomatological and biochemical constituents of WMC are only partially known. LÄS MER

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; patologisk anatomi; Patologi allmän ; pathological anatomy; General pathology; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; executive dysfunction; Clinical physics; magnetic resonance imaging; diffusion tensor imaging; neuropathology; microvascular pathology; astrocytes; myelin; oligodendrocytes; white matter disease; Alzheimer s disease; neuropsychology; neuropsykologi; Neurologi; neurophysiology; neurofysiologi; Psychiatry; clinical psychology; psychosomatics; Psykiatri; klinisk psykologi; psykosomatik; Neurology;

   Sammanfattning : Alzheimer's disease (AD) is the most prevalent type of dementing disorder. The cortical pathology of AD has been recognized for almost a century. In later years, an associated pathological feature of AD has been identified which affects the white matter. LÄS MER

4. 3. The matter of white and gray matter in cognitive impairment

   Författare :Soheil Damangir; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Cognitive impairment spans from minor subjective cognitive impairment to disabling dementia. Many biomarkers have been developed to monitor different aspects of cognitive impairment. Magnetic resonance imaging is the most used neuroimaging biomarker in research and can measure gray matter (GM) and white matter (WM) changes. LÄS MER

5. 4. Craniopharyngioma. Morbidity and Structural Changes in the Brain

   Författare :Sigríður Bára Fjalldal; Lund Medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; craniopharyngioma; hypothalamus; hypothalamic obesity; metabolism; cognition; magnetic resonance imaging; diffusion tensor imaging; white matter lesions; morbidity; cardiovascular risk; craniofaryngiom; hypotalamus; hypotalamisk fetma; ämnesomsättning; kognition; magnetkameraundersökning; vitsubstansförändringar; dödlighet; hjärt-kärlsjukdomar;

   Sammanfattning : Hypothalamus (HT) is a brain structure which serves as a coordination center for several vital body functions. Craniopharyngioma (CP) is a pituitary tumor with high morbidity, primarily due to HT lesion. LÄS MER

7. 5. Magnetic resonance imaging in dementia : a study of brain white matter changes

   Författare :Lena Bronge; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Non-specific white matter changes (WMC) in the brain are common findings in the elderly population. Although they are frequently seen in non-demented persons, WMC seem to be more common in demented patients.The significance of these changes, as well as their pathophysiological background is incompletely understood.
