Journal ArticleDOI
Dementia spectrum disorders: lessons learnt from decades with PET research
TL;DR: The dementia spectrum encompasses a range of disorders with complex diagnosis, pathophysiology and limited treatment options, and PET tracers have been developed to target specific proteinopathies (amyloid, tau and α-synuclein), glucose metabolism, cholinergic system and neuroinflammation.
Journal ArticleDOI
Loss of phosphodiesterase 4 in Parkinson disease: Relevance to cognitive deficits
Flavia Niccolini,Heather Wilson,Gennaro Pagano,Christopher Coello,Mitul A. Mehta,Graham E. Searle,Roger N. Gunn,Eugenii A. Rabiner,Thomas Foltynie,Marios Politis +9 more
TL;DR: Findings demonstrate loss of PDE4 expression in the striato-thalamo-cortical circuit, which is associated with deficits of spatial working memory in patients with PD.
Journal ArticleDOI
Reduplicative paramnesia: a review.
Marios Politis,Clare Loane +1 more
TL;DR: There does appear to be a consensus that RP may have a neurologic rather than psychiatric cause and that right and bifrontal lesions as well as the cognitive dissonance associated with memory, visuospatial and impaired conceptual integration are common factors in RP presentation.
Journal ArticleDOI
Presynaptic dopaminergic terminal imaging and non-motor symptoms assessment of Parkinson’s disease: evidence for dopaminergic basis?
TL;DR: Some non-motor symptoms in PD may have a dopaminergic basis and in this paper, the authors investigate the evidence for this based on imaging techniques using dopamine-based radioligands.
Journal ArticleDOI
The serotonergic system in Parkinson’s patients with dyskinesia: evidence from imaging studies
TL;DR: An integrative multimodal imaging approach combining PET and MRI imaging techniques is needed to fully understand the mechanisms underlying the development of LIDs and GIDs in Parkinson’s patients.
