<s>[INST] my 17 year old daughter has has a few episodes of sycope lately and blackness of vision . She is otherwise healthy and an athlete. We were advised to see a neurologist whohad her undergo an Bloodwork-clean, MRI- clean, EEG-some spikes while sleeping. He says she could be prone to seizures but not really What does that mean? [/INST] Dear parent, Thanks for your Quertle problem that your daughter has is common complaint and answer lies in history and not in investigations. Thus, first let us see what your daughter has. We may not conclude it as syncope and let us consider as a paroxysmal event what all happens before during and after event is of prime importance. What are the preceding complaints and what is her motor status during the event. How long or short duration are the events and at what level of consciousness is she at time of event is very important Now coming to investigations - EEG showing spikes is not epilepsy. The spikes in EEG could be a hereditary trait. There are a lot of normal variants which could cause spikes I think you may also require a TILT TABLE TEST which is positive can clinch diagnosis </s>
