Could any one tell me what might cause snyope? I have had two with injury and one without. Alot of test but no results. Drs are stumped as to why.

Many answers. Sycope or sudden loss of consciousnes can have a variety of causes. The cause is often benign. Cardiac arrythmia, seizure and reflex drop in blood pressure are all possibilities. In some studies between 18 and 41% of cases are unexplained. If your evaluation has been exhustive, you may have to live with the uncertainty. Talk to your doctor to see if further eval is needed or appropriate.
