Neuroimage
. 2015 Jul;
119:296-304.
PMID: 26143204
As an indicator of synchronous neural activity, resting-state functional networks are influenced by neuropathological and neurochemical changes in degenerative diseases. To further advance understanding about neurochemical and neuropathological basis for...

Topography of cortical thinning associated with white matter hyperintensities in Parkinson's disease
Ham J, Yun H, Sunwoo M, Hong J, Lee J, Sohn Y, et al.
Parkinsonism Relat Disord
. 2015 Feb;
21(4):372-7.
PMID: 25697488
Background: Although white matter hyperintensities (WMHs) are associated with cognitive impairments in Parkinson's disease (PD), the relationships between WMHs and cortical atrophy in regard to cognitive impairments are unknown. Here,...

Hum Brain Mapp
. 2015 Feb;
36(5):1716-27.
PMID: 25640661
Olfactory performance in Parkinson's disease (PD) is closely associated with subsequent cognitive decline. In the present study, we analyzed the olfaction-dependent functional connectivity with a hypothesis that olfactory performance would...

J Mov Disord
. 2015 Jan;
8(1):21-5.
PMID: 25614782
Objective: Olfactory and emotional dysfunctions are very common in patients with Parkinson's disease (PD). Olfaction and emotions share common neuroanatomical substrates. Therefore, in this study, we evaluated the association between...

Parkinsonism Relat Disord
. 2014 Jul;
20(9):999-1003.
PMID: 25001316
Background: Subjective cognitive decline (SCD) has gained attention as a predictor of future cognitive decline in neurodegenerative diseases. Based on the hypothesis that different pathologies may distinctly contribute to SCD,...

Hum Brain Mapp
. 2014 Jun;
35(11):5431-41.
PMID: 24938993
Parkinson's disease (PD) is characterized by degenerative changes of nigral dopamine neurons, resulting in the dopaminergic denervation of the striatum. Resting state networks studies have demonstrated that dopamine modulates distinct...

PMID: 24920492
Cerebral microbleeds (CMBs) are known to be associated with cognitive impairments in the elderly and in patients with various diseases; however, the nature of this association has not yet been...

PMID: 24719485
Objective: To investigate whether the magnitude of presynaptic dopamine depletion is a risk factor for the development of levodopa-induced dyskinesia (LID) in Parkinson disease (PD) by quantitatively analyzing (18)F-FP-CIT PET...

. 2014 Feb;
35(7):1739-43.
PMID: 24507441
Increasing evidence suggests that subjective cognitive decline (SCD) is a potential predictor of future cognitive decline or dementia. We investigated whether SCD in patients with Parkinson's disease (PD) is a...

Parkinsonism Relat Disord
. 2013 Nov;
20(2):186-91.
PMID: 24262869
Objective: To explore whether olfactory performance acts as a cognitive reserve in non-demented patients with Parkinson's disease (PD). Methods: Patients with non-demented PD (n = 119) underwent T1-weighted MRI and...
