Blacking out, no memory of events.?

Okay, so, My boyfriend is eighteen years old and has been blacking out for some time now. He says it only happens when he's extremely happy or excited. He doesn't really change much, it's still him, but there is a slight difference that i cant seem to put my finger on. Anyways, when these blackouts occur he hasn't been drinking or on any drugs, so I believe it's a neurological [sp] condition.After these blackouts he can't remember anything that happened during. To put it the simplest way, it's like a blackout from excessive drinking, without the alcohol. I've already somewhat heard "absent seizures", "Dissociative Fugue" and "Dissociative Amnesia" none of which seems to be quite right for his condition. I would really appreciate information from highly credible resources such as doctors or any other medical professional, or medical websites.

Please and Thank you!Blacking out, no memory of events.?
Blacking out is listed as an alternate name or description for symptom Vasovagal Syncope.



Vasovagal syncope occurs when the part of your boyfriend nervous system that regulates heart rate and blood pressure malfunctions in response to a trigger, such as the sight of blood.



Your boyfriend heart rate slows, and the blood vessels in your boyfriend legs widen. This allows blood to pool in his legs, which lowers blood pressure. This drop in blood pressure and slowed heart rate quickly cause diminished blood flow to his brain, and faints.



If your boyfriend feels like he might faint, let him lie down and lift up his legs. This allows gravity to keep blood flowing to his brain. If he can't lie down, let sit down and put his head between knees until he feels better.



Vasovagal syncope is usually harmless and requires no treatment. But his doctor may recommend tests to rule out more-serious causes of fainting, such as heart disorders.



Take care as always!
A drug addict and an alchoholic.. hmmm. This is a tough question.



Perhaps he does not eat well enough to counter-act the effects of the drugs or alcohol. He may be suffering from an eating disorder because all his money is being spent on drugs and alcohol.



He probably has been abusing substances of addiction since his teens and, possibly had some disturbing childhood problems. I'd say that if he doesn't curb his ways, he may not live to his next birthday.Blacking out, no memory of events.?
