The idea of "inborn errors of metabolism
" is used as an example of chemical differences, although it is not clear how this term is truly defined in the book, as inborn errors of metabolism
are typically associated with specific enzyme deficiencies (such as tyrosinemia or galactosemia) that often can be improved by dietary elimination, medications, or removal of the organ with the missing enzyme component (as in liver transplantation).
Determination of etiology is critical, both for treatment and disease prognosis.5 Birth asphyxia is the commonest cause of neonatal seizures.3 Other causes include septicemia with or without CNS infection, transient metabolic disorder (hypoglycemia, hypocalcaemia, hypomagnesemia and hypernatremia.6 Hypocalcaemia is the commonest metabolic disorder followed by hypoglycemia), intracranial bleed, brain malformation, inborn errors of metabolism
(urea cycles defects, mitochondrial abnormalities), tetanus, kernicterus and pyridoxine dependency.6,7 Other causes include polycythemia, maternal narcotic withdrawal, drug toxicity (e.g.
