I don't think your doc has given you all the information. Please get a copy of the MRI or CT, and read the report. There has to be a name. Hole is frankly, not medical.
Get another opinion from a doctor who will be straight with you. If there is loss or damage to a part of the brain, it all depends on location - and you need to know if the hole was always there, of it it just formed.
Your current doctor is not being straight with you.
thanks it is my nephew and my sister lost him to grandparents the information I got was from them because I could not make appointment. WE are sharing custody of the two boys and she hasn't given me anything from the appointment, but I will do that or take him to someone else.
