Abnormal fractional amplitude of low-frequency fluctuations in MOG-lgG optic neuritis patients: a resting-state functional MRI study

open access: yesJournal of Integrative Neuroscience, 2022
Optic neuritis (ON) is a general term for inflammation of any part of the optic nerve resulting from demyelination or infection. The number of patients with MOG-lgG antibody-related optic neuritis is increasing recently.

Abnormal fALFF in OCD.

open access: yes, 2013
Four regions, mainly in the ACC, the MCC, the brainstem and the cerebellum, showed increased fALFF in subjects with OCD compared to the HC group (yellow color, small letters a to d).

ALFF/fALFF: a metanalysis and systematic review on the continuum between schizophrenia and bipolar disorder

open access: yes, 2022
As evidence continues to gather on a biological spectrum of continuum between schizophrenia and bipolar disorder, it is necessary to elucidate the neuroimaging correlates of these two diagnoses. Rather than an approach based on functional connectivity or

Metabolic and Microvascular Risk Factors Associated With Brain Health in Type 1 Diabetes

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 9, Page 1937-1946, September 2026.
ABSTRACT We examined relationships between metabolic factors, microvascular complications, and brain health in adults with type 1 diabetes. Fifty‐one adults were assessed for metabolic risk factors, microvascular complications, and cognitive function, with a subset completing brain MRI.

Prefrontal Neurovascular Coupling Abnormalities Associated With Cognitive Performance in Multiple Sclerosis

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
Multimodal MRI showed reduced global CBF‐ALFF coupling and increased medial prefrontal CBF/ALFF ratios in multiple sclerosis. The mPFC abnormality was associated with lower cognitive performance and greater disability. ABSTRACT Background Cognitive impairment is a prevalent and debilitating feature in multiple sclerosis (MS), yet its pathophysiology ...

Posture‐Related Regional Homogeneity Abnormalities in Cerebral Small Vessel Disease: A Multi‐Position MRI Study

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
Patients with CSVD showed higher upright ReHo in anterior cingulate gyrus (ACG) than NCs, and supine‐upright comparison revealed widespread ReHo alterations. Upright ACG ReHo and posture‐related ReHo changes in the hippocampus, putamen, and calcarine cortex were associated with poorer cognition and greater CSVD burden, suggesting that upright imaging ...

Repetitive Transcranial Magnetic Stimulation in Alzheimer's Disease Cognitive Impairment: A Narrative Review of Clinical Trials

open access: yesHealth Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background and Aims Alzheimer's disease (AD), primarily characterized by cognitive impairment, places an immense burden on patients and caregivers. Non‐invasive neuromodulation with repetitive transcranial magnetic stimulation has been proposed to improve cognition in mild to moderate AD. This narrative review aimed to summarize clinical trial
