2857. Amplitude
of low-frequency fluctuation (ALFF) alterations in heart
transplant patients with cognitive impairment: A resting-state
fMRI study
Q. Qin, W. Chen, J. wang, Z. Lei
Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China
Impact: ALFF
may serve as a potential neuroimaging marker to help
identify patients at higher risk of cognitive impairment
after heart transplantation. This would facilitate early
intervention and personalized care.

2858. Resting-state
BOLD fMRI cerebrovascular reactivity in youth with congenital
heart disease
Z. Potvin-Jutras, S. Sanami, K. Easson, G. Gilbert, C.
Saint-Martin, C. Steele, M. Brossard-Racine, C. Gauthier
Concordia University, Montreal, Canada
Impact: We observed lower cerebrovascular reactivity
(CVR) in youth with congenital heart disease (CHD), with
those with single-ventricle physiology most affected,
especially in the anterior cerebral artery territory.
Females with CHD revealed poorer CVR in the middle cerebral
artery territory.

2859. Increases
in Resting State Network Connectivity in Sickle Cell Anaemia
with Spatially Constrained Independent Component Analysis
M. Lee, F. Kirkham, K. Shmueli
University College London, London, United Kingdom
Impact:
We identified increased functional connectivity within and between several large resting-state networks in sickle cell anaemia (SCA). This work may contribute to the characterisation of a signature neuroimaging profile in important disease manifestations, such as cognitive deficit and chronic pain. |

2860. Systematically
altered connectome gradient in patient with Type2-diabetes
mellitus: Potential effect on cognitive function
H. Ran, t. zhang
The Affiliated Hospital of Zunyi Medical University, Zunyi, China
Impact: These findings improve our comprehension the
neurobiological mechanisms that underlie cognitive function
and offer potential imaging biomarkers for the assessment of
cognitive function in T2DM.

2861. Altered
static and dynamic functional connectivity in amygdala
subregions in depressed type 2 diabetes patients
J. Tian, L. Zhao, G. Huang, J. Cao, C. Yang
Gansu Provincial Hospital, Lanzhou, China
Impact: This study underscores the significance of
dynamic fluctuations in comprehending depressive symptoms
associated with T2DM, thereby offering valuable insights for
clinical assessment.

white matter functional networks in type 2 diabetes mellitus
with and without mild cognitive impairment
Y. Huang, D. Zhang, X. Zhang, X. Lei, X. Zhang, K. Ai
Shaanxi Provincial People's Hospital, Xi 'an, China
Impact: This study explored the change patterns of WM
functional connectome and global topological properties in
patients with T2DM under different cognitive states, which
can provide a neuroimaging basis for revealing T2DM-related
brain damage from the perspective of WM function.

pronounced than structural changes in the visual pathway,
including the LGN, visual cortex, and fusiform gyrus, in
glaucoma. This highlights the importance of studying
functional impairments in higher-level visual areas in
glaucoma.
