Journal ArticleDOI
Age-related dopamine D2/D3 receptor loss in extrastriatal regions of the human brain.
Valtteri Kaasinen,Harry Vilkman,Jarmo Hietala,Kjell Någren,Hans Helenius,Hans Olsson,Lars Farde,Juha O. Rinne +7 more
TL;DR: The results indicate that the previously demonstrated age-related decline in striatal dopamine D2 receptors extends to several extrastriatal regions in normal human males, and the rate of D2/3R decline may be faster in the frontal cortex as compared to the temporal and thalamic regions.
Journal ArticleDOI
Role of the dopaminergic system in chronic pain -- a fluorodopa-PET study.
Satu K. Jääskeläinen,Juha O. Rinne,Heli Forssell,Olli Tenovuo,Valtteri Kaasinen,Pirkko Sonninen,Jörgen Bergman +6 more
TL;DR: The present result provides direct evidence of the involvement of the nigrostriatal dopaminergic system in pain for the first time in a clinical pain condition.
Journal ArticleDOI
Hippocampal and prefrontal atrophy in patients with early non-demented Parkinson’s disease is related to cognitive impairment
TL;DR: Non-medicated, non-demented patients with early stage PD show hippocampal and prefrontal atrophy, whereas sustained attention is related to hippocampal atrophy.
Journal ArticleDOI
Functional imaging studies of dopamine system and cognition in normal aging and Parkinson's disease
Valtteri Kaasinen,Juha O. Rinne +1 more
TL;DR: The literature related to age-associated phenomena in the dopamine system studied with in vivo imaging is covered, with the focus on describing and discussing the relationships between aging, cognition and the dopaminergic system in healthy subjects and in patients with Parkinson's disease.
Journal ArticleDOI

TL;DR: In this paper, the effects of different gambling outcomes on dopamine release were evaluated with [11C]raclopride positron emission tomography (PET) during gambling with an ecologically valid slot machine gambling task.
