1. 41. Functional brain imaging of cognitive status in Parkinson's disease

   Författare :Urban Ekman; Johan Eriksson; Lars Nyberg; Lars Forsgren; Oury Monchi; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson’s disease; functional MRI; Mild cognitive impairment; Working memory; Parkinson’s disease dementia; BOLD;

   Sammanfattning : Parkinson’s disease (PD) is next to Alzheimer’s disease (AD) the second most common neurodegenerative disease. PD has traditionally been characterised as a motor disorder, but more recent research has revealed that cognitive impairments are frequent. LÄS MER

3. 42. Aerobic fitness and healthy brain aging : cognition, brain structure, and dopamine

   Författare :Lars Jonasson; Carl-Johan Boraxbekk; Katrine Riklund; Emrah Düzel; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aerobic exercise; VO2; working memory; executive function; freesurfer; striatum; dopamine; D2-receptors; [11C]raclopride;

   Sammanfattning : Background: Performing aerobic exercise and maintaining high levels of aerobic fitness may have positive effects on both brain structure and function in older adults. Despite decades of research however, there is still a rather poor understanding of the neurocognitive mechanisms explaining the positive effects of aerobic exercise on cognition. LÄS MER

4. 43. Deafblindness : Theory-of-mind, cognitive functioning and social network in Alström syndrome

   Författare :Hans-Erik Frölander; Claes Möller; Björn Lyxell; Erland Hjelmquist; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alström syndrome; Deafblindness; Theory-of-mind; Communication; Verbal ability; Executive functions; Working memory; Health problems; Friendship; Social network; Handikappvetenskap; Disability Research;

   Sammanfattning : This thesis addresses young adults with Alström syndrome (AS). AS causes acquired deafblindness, a severe, progressive, combined auditory and visual impairment affecting daily life and self-reliance to a degree that full participation depends on help from others and society.

5. 44. The architecture of the aging brain : functional reorganization, structural changes, and the role of dopamine receptors

   Författare :Robin Pedersen; Alireza Salami; Anna Rieckmann; Anders Wåhlin; Lars Nyberg; Roser Sala-Llonch; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain architecture; functional connectivity; dopamine; aging; cognition; memory; functional magnetic resonance imaging; positron emission tomography; graph theory; Laplacian eigenmapping; gradient;

   Sammanfattning : Aging is associated with reorganization of functional brain architecture, potentially leading tocognitive decline in older age. However, the mechanisms responsible for alterations in functionalbrain architecture remain poorly understood. LÄS MER

7. 45. Assessing cognitive spare capacity as a measure of listening effort using the Auditory Inference Span Test

   Författare :Niklas Rönnberg; Stefan Stenfelt; Mary Rudner; Thomas Lunner; Larry Humes; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Listening effort; Cognitive spare capacity; Speech-in-noise; Cognition; Working memory; Updating; Hearing impairment;

   Sammanfattning : Hearing loss has a negative effect on the daily life of 10-15% of the world’s population. One of the most common ways to treat a hearing loss is to fit hearing aids which increases audibility by providing amplification. Hearing aids thus improve speech reception in quiet, but listening in noise is nevertheless often difficult and stressful. LÄS MER
