During this podcast, Dr. O'Neill will discuss the following questions:

  • Which factor affects children’s brain and intellectual development more, genes or environment? 
  • How do epigenetic factors affect brain development, especially myelination? 
  • At what age can we say a child is fully developed in executive functions. Are there notable indications to suggest this? 
  • Is there any room to reverse brain damage caused by lack of essential nutrients?
