The medical term for fainting is syncope, but it’s more commonly known as “passing out.” A fainting spell generally lasts from a few seconds to a few minutes.
Feeling lightheaded, dizzy, weak, or nauseous sometimes happens before you faint.
Some people become aware that noises are fading away, or they describe the sensation as “blacking out” or “whiting out.”
Even mild head injuries can lead to a concussion. This can cause you to have memory issues and confusion. Most of the time, if you have a concussion, you may not remember the events that led to the injury.
Seizures can also cause memory problems. Sometimes, directly after a seizure, you can enter a state of post-ictal confusion. This means you may be confused and not remember what happened directly before the seizure or what you did after the seizure happened. Generally, your memory of those events will come back within 5-30 minutes, once the post-ictal state is over.
A blackout from intoxication is due to a brain malfunction. Your brain stops saving the things you do as memories. You may act normally and do things like socialize, eat, drive, and drink. But your brain is impaired and does not record your memories sufficiently during this time.
What Are the Signs?
Symptoms can vary. Some people become quiet and withdrawn, while others get nervous and upset. They may:
Struggle to focus
Seem groggy, like they can’t wake up all the way
Mumble or say things that don’t make sense
Not recognise you or know where they are
A full recovery usually takes a few minutes. If there’s no underlying medical condition causing you to faint, you may not need any treatment.
