Infant of diabetic mother with weight 3.8 Kg presented with seizures after 16 hours of birth.What is the cause –
Hypoglycemia
Hypocalcemia
Birth asphyxia
Intraventricular hemorrhage
Electrolyte disturbances, including hypoglycemia and hypocalcemia, are commonly seen in association with infants of diabetic mother and may result in early-onset seizures.
Sorry friends, I could not find any reference which has directly mentioned that hypoglycemia is a more common cause of seizure than hypocalcemia in infants of diabetic mother.
I was just able to find following two statements : -

"Infants of diabetic mother are most at risk for hypoglycemia which can result in seizure".
"Infant of diabetic mothers with seizures, that does not respond to glucose should have their serum calcium measured"

From these two statements, it seems to me that hypoglycemia is a more common cause of seizures in infants of diabetic mother.
