[question name="Sarah" location="via e-mail"] My eventer has recently been diagnosed with seizures. However, despite blood tests, we have no idea what causes them. The episodes last for approximately two minutes, and once they are over, he is completely normal again. He has never had them while being ridden, and they mostly occur in the paddock.

We’ve moved three times in the last few years, and his food has been altered, so those shouldn’t be causes. He has never been injured or hurt before, and this illness has been a nasty shock. What causes this? Is there anything we can do?
