Hi all. My 13 year old son is having in excess of 250 black outs a day. This started 3 months ago and has increased to this level. He has had MRI, EEG, blood tests, plus 24 blood pressure and heart monitoring, all results are within normal limits. Now refereed to psychologist, but they do not think it's anxiety based, but medical. The blackouts have not increased in frequency for 2 weeks, and usually last between 3 and 30 seconds. I'd be grateful for any suggestions. Best wishes, Lynne.
