Background: Children with hyperinsulinaemic hypoglycaemia (HH) are at a high risk of brain injury, while children with ketotic hypoglycaemia (KH) are believed to be neurologically normal. Hippocampus is known to be susceptible to hypoglycaemia, and is one of the key structures in the memory system. Our objective was to ascertain if children with HH sustain greater hippocampal injury and memory deficits in comparison to children with KH.Methods: Twenty on...

Background: The severe neurodevelopmental phenotype of untreated congenital hypothyroidism exemplifies the critical role of thyroid hormones (TH) in CNS development, acting via thyroid hormone receptor α1 (TRα1) on cortical neurogenesis, cerebellar development and oligodendrocyte differentiation. We have identified the first humans with defective TRα1 and investigated neurocognitive phenotype and CNS abnormalities in this disorder.Methods:...
