Fainting is usually caused by a decrease in blood flow to the brain. This has many possible causes. In most cases the cause is psychological. This is called vasovagal syncope.

Loss of consciousness is a partial or complete loss of the perception of yourself and all that around you.

When the loss of consciousness is temporary and there is a spontaneous recovery, that is to say, “a blackout”, in medical terms it is known as a syncope. Syncope is responsible for almost one in every 30 visits to emergency departments.
