Thanks Nancy for the reply.    He has just had another episode so I think fully recovering the speech is going to be a slow process.  I feel reassured by your comments.  It is just so hard to know what is going on at times.   I have tried ringing and emailing headache Australia with no response (1 week) but followed the link and rang some of the clinics listed but they do not treat children.  I was however given the name of the Paediactric Neurologist we have currently got a referral to.  Seems he has a special interest in headache so it sounds promising.    As yet we do not have even an appointment.  We had to fax the referral off and the appointment will be mailed out to us.   Thanks again for you support.  It means alot to get some clear answers and information.
