Objective To examine whether hippocampal volume loss is primarily associated with
cognitive status or pathologic β-amyloid 1–42 (Aβ42) levels, this study compared …

Background Global hippocampal atrophy is a hallmark of Alzheimer's dementia and has
been similarly reported in Parkinson's disease dementia (PDD). However, there is limited …

Objective Hippocampal atrophy has been associated with mild cognitive impairment (MCI) in
Parkinson's disease (PD). However, literature on how hippocampal atrophy affects the …

Background Neuropathological studies have shown that the hippocampus is affected in
Parkinson's disease (PD) with cognitive impairment. Our goal was to assess the longitudinal …

Neuropathological studies show the hippocampus is affected in Parkinson's disease (PD),
with the second subfield of the cornu armonis (CA2) being the most involved. Our aims were …

Cognition is often affected early in Parkinson's disease (PD). Lewy body and amyloid β (Aβ)
pathology and cortical atrophy may be involved. The aim of this study was to examine …

This study aimed to explore morphological changes of hippocampal subfields in patients
with multiple system atrophy (MSA) with and without cognitive impairment using FreeSurfer …

Hippocampal dysfunctions may play an important role in the non-motor aspects of
Parkinson's disease (PD), including depressive and cognitive symptoms. Fine structural …

Objectives To investigate the volumetric alterations of hippocampal subfields and identify
which subfields contribute to mild cognitive impairment (MCI) in multiple system atrophy …

Objective Parkinson's disease (PD) episodic memory impairments are common; however, it
is not known whether these impairments are due to hippocampal pathology. Hippocampal …
