Revealing heterogeneity in mild cognitive impairment based on individualized structural covariance network [PDF]

Alzheimer’s Research & Therapy
Background Mild cognitive impairment (MCI) is a heterogeneous disorder with significant individual variabilities in clinical and biological features. Abnormal inter-regional structural covariance suggests disruption of the brain structural network in MCI.

Exploring the core network of the structural covariance network in childhood absence epilepsy [PDF]

Heliyon, 2023
Childhood absence epilepsy (CAE) is a generalized pediatric epilepsy, which is generally considered to be a benign condition since most children become seizure-free before reaching adulthood. However, cognitive deficits and changes of brain morphological

Topological abnormality of structural covariance network in MRI-negative frontal lobe epilepsy [PDF]

Frontiers in Neuroscience, 2023
BackgroundFrontal lobe epilepsy (FLE) is the second most common type of focal epilepsy, however, imaging studies of FLE have been far less than Temporal lobe epilepsy (TLE) and the structural findings were not consistent in previous literature ...

Hippocampal morphological atrophy and distinct patterns of structural covariance network in Alzheimer’s disease and mild cognitive impairment [PDF]

Frontiers in Psychology, 2022
Elucidating distinct morphological atrophy patterns of Alzheimer’s disease (AD) and its prodromal stage, namely, mild cognitive impairment (MCI) helps to improve early diagnosis and medical intervention of AD. On that account, we aimed to obtain distinct
