Vasovagal syncope means that your parasympathetic nervous system (which calms and quiets your body) kicked in too strongly, causing a drop in blood pressure. This drop in blood pressure causes a lot of things to happen, two of which are fainting (syncope) and headache. The drop in pressure changes the pressure in your head as well, and the membrane surrounding your brain is sensitive to such pressure changes, and generally causes pain in the form of a head ache. When people take nitro for heart pain, the result is a drop in blood pressure, usually with an accompanying headache.
I think that exertional syncope is a kind of cardiac syncope. During exertion the patient with heart disease would be unable to supply enough oxygen to the brain, causing dizziness.
Syncope is a loss of consciousness or fainting, sometimes caused by lack of oxygen to the brain, but is different to Epilepsy. Seizures in Epilepsy are caused by abnormal electrical activity in the brain. So Syncope would not be a cause of seizures.
Seeing zig zag colored lines is a sign that someone might be about to have a migraine headache. A migraine is an intense headache usually accompanied by more severe symptoms.
Could be a sign of a stroke (Cerbrovascular Accident) or Syncope.
If you go just one day without water then you can get dehydrated and faint or get a massive headache. The longest a human can live without water is (max.) three days, then you will die or get sent to an ER for a long, long, long time. If you have Vascomotor Syncope, you need at least one quart of water each day instead of eight ounzes.
Heat and/or cold is often an effective way to lessen a headache.
That would be the migrain.

Headache is a symptom of pain in the head. Migraine is a disease which can include headache. It is possible to have short pain in your head, but that would be a headache - a symptom.

If a headache is the "worst headache on one's life", a trip to the hospital is recommended. other symptoms requiring a professional medical treatment are a headache accompanied by nausea, vomiting, blurred vision, and any change in behavior.
