Blackouts can have many causes including heart issues, brain problems, low blood pressure, and nerves. The heart can cause blackouts due to valve problems, fast rhythms, or slow rhythms. The brain can cause blackouts from strokes or seizures. Low blood pressure, especially in older people or those on medication, can lead to blackouts. Simple faints from overheating or stress on the nerves are the most common cause of blackouts. Tests like echocardiograms and electroencephalograms can help determine the root cause. Driver's licenses may be held until the cause of blackouts is properly identified to ensure safety.
