Dopaminergic modulation of high‐level cognition in Parkinson’s disease: the role of the prefrontal cortex revealed by PET
TL;DR: It is suggested that L-dopa ameliorates high-level cognitive deficits in Parkinson's disease by inducing relative blood flow changes in the right dorsolateral prefrontal cortex.
Journal ArticleDOI
EFNS-ENS Guidelines on the diagnosis and management of disorders associated with dementia
Sandro Sorbi,Jakub Hort,Timo Erkinjuntti,Timo Erkinjuntti,Tormod Fladby,Guido Gainotti,Hakan Gurvit,Benedetta Nacmias,Florence Pasquier,Bogdan Ovidiu Popescu,Irena Rektorová,Dorota Religa,Dorota Religa,Robert Rusina,Martin N. Rossor,Reinhold Schmidt,Elka Stefanova,Jason D. Warren,Ph. Scheltens +18 more
TL;DR: The aim is to present a peer‐reviewed evidence‐based statement for the guidance of practice for clinical neurologists, geriatricians, psychiatrists and other specialist physicians responsible for the care of patients with dementing disorders.
Journal ArticleDOI
Glucose Homeostasis in Huntington Disease: Abnormalities in Insulin Sensitivity and Early-Phase Insulin Secretion
Nebojsa Lalic,Jelena Maric,Marina Svetel,Aleksandra Jotic,Elka Stefanova,Katarina Lalic,Nataša Dragašević,Tanja Milicic,Ljiljana Lukic,Vladimir S. Kostic +9 more
TL;DR: Besides impairment in insulin secretion capacity, a simultaneous decrease in insulin sensitivity, with an increase in the insulin resistance level, was found in normoglycemic patients with HD compared with controls, implying that progression of the insulin secretion defect in HD may lead to a failure to compensate for insulin resistance.
Journal ArticleDOI
Mild cognitive impairment in Parkinson's disease is associated with a distributed pattern of brain white matter damage.
Federica Agosta,Elisa Canu,Elka Stefanova,Lidia Sarro,Aleksandra Tomić,Vladana Špica,Giancarlo Comi,Vladimir S. Kostic,Massimo Filippi +8 more
TL;DR: DT MRI might contribute to the identification of structural changes in PD‐MCI patients prior to the development of dementia by helping to identify abnormalities of frontal and interhemispheric WM connections.
Journal ArticleDOI
Brain structural and functional connectivity in Parkinson's disease with freezing of gait.
Elisa Canu,Federica Agosta,Elisabetta Sarasso,Maria Antonietta Volontè,Silvia Basaia,Tanja Stojkovic,Elka Stefanova,Giancarlo Comi,Andrea Falini,Vladimir S. Kostic,Roberto Gatti,Massimo Filippi +11 more
TL;DR: To use a multimodal approach to assess brain structural pathways and resting state functional connectivity abnormalities in patients with Parkinson's disease and freezing of gait (PD‐FoG).
