Abstract

To study the relationship between clinical and imaging features in neonates with hypoglycemic brain injury. Sixteen neonates with hypoglycemic brain injury received a MRI scan with the sequences of T1WI, T2WI and DWI within 48 hrs after admission. Of the 16 patients, 11 received second MRI scan at two weeks of their lives, and 3 received a third scan at ages of 1-5 months. Repeated seizures, lethargy and hypotonia were common clinical manifestations. Five severe hypoglycemia cases presented coma, respiratory failure and even cardiorespiratory arrest. The minimum mean value of whole blood glucose (WBG) in the 16 patients was 0.98+/-0.43 mmol/L, and that of the 5 severe cases was 0.72+/-0.42 mmol/L. EEG showed intermittent low voltage in the mild hypoglycemia cases. Flatten pattern and even electrocerebral silence was noted in the severe cases. Occipital and parietal cortexes (OPC) injuries were found in all of the 16 patients and 2 patients had concurrent periventricular white matter injury. A widespread involvement of cortex was found in the 5 severe hypoglycemia cases in which 1 showed widespread involvement of white matter, and 2 showed involvement of basal ganglia and thalamus. The 5 patients with widespread cortex injury an...Continue Reading

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.

Brain developing: Influences & Outcomes

This feed focuses on influences that affect the developing brain including genetics, fetal development, prenatal care, and gene-environment interactions. Here is the latest research in this field.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
