Blackouts/Collapse Treatments in Dubai

A blackout is a temporary partial or complete loss of memory that is usually characterized by a period of unconsciousness or lack of complete awareness. Right before experiencing a blackout, you may have blurred vision, feel confused, or lose your balance and fall down. Blackouts do not erase or interfere with the memories made before it happens.

Blackouts can occur as a result of excessive consumption of alcohol, brain damage, side effects of certain drugs or disorders affecting the brain such as epilepsy.

Causes of Blackouts

Fainting is one of the common causes of a blackout. It occurs when the heart rate drops, and the blood vessels widen thus resulting in low blood pressure. Blackouts can also be caused by a traumatic event, substances, diseases or disorders that involve injury to the head.
