Observations of the authors regarding main MRI symptoms of agenesis of the corpus callosum (ACC) and literature review on the structure of the corpus callosum in normalcy and pathology are presented. The authors emphasize that some cases of isolated ACC has been found during routine prenatal ultrasound examination. In this regard, prenatal MRI is more effective. In 74% patients with ACC, MRI results are consistent with the results of ultrasound and CT. MRI has advantages in the differentiation of inherited corpus callosum malformation as well as concomitant CNS abnormalities.

Chronic traumatic encephalopathy (CTE) has attracted attention due to sports-related head trauma or repetitive mild traumatic brain injury (mTBI). However, the pathology of CTE remains underexplored. Reproducible and quantitative model of CTE has yet to be established.

Introduction: Traumatic brain injury (TBI) is one of the leading causes of death and disability worldwide. Treatments for TBI patients are limited and none has been shown to provide prolonged and long-term neuroprotective or neurorestorative effects. A growing body of evidence suggests a link between TBI-induced neuro-inflammation and neurodegenerative post-traumatic disorders.

We describe a set of monozygotic twins with GRIN2B-related neurodevelopmental disorder (GRIN2B-ND) who exhibited distinct clinical and imaging characteristics due to a de novo heterozygous pathogenic variant in the GRIN2B gene (c.2453T>C, p.Met818Thr).

Impaired muscle mitochondrial oxidative capacity is associated with future cognitive impairment, and higher levels of PET and blood biomarkers of Alzheimer's disease and neurodegeneration. Here, we examine its associations with up to over a decade-long changes in brain atrophy and microstructure. Higher in vivo skeletal muscle oxidative capacity via MR spectroscopy (post-exercise recovery rate, k) is associated with less ventricular enlargement and brain aging progression, and less atrophy in specific regions, notably primary sensorimotor cortex, temporal white and gray matter, thalamus, occipital areas, cingulate cortex, and cerebellum white matter.

Background: Intravenous lipid emulsions are an essential component of nutritional support for very preterm infants. Many neonatal intensive care units have transitioned from traditional soybean oil-only to fish oil-containing multicomponent lipid emulsions, but the neurodevelopmental implications have not been well-explored. The primary aim of this study was to assess extrauterine third trimester brain growth in very preterm infants supported with soybean oil-only compared to fish-oil containing multicomponent lipid emulsions; white matter development and neurobehavioral regulation at term were also investigated.
