Blackouts can be defined as a temporary loss of consciousness, which could occur as a result of various reasons. It is a common side effect of drug/alcohol consumption, but can also be related to problems with blood circulation, or conditions that affect the brain (e.g.: epilepsy).
Blackouts are often accompanied by fainting, which can be referred to as the sudden drop in heart rate and blood pressure. Blackouts, although temporary, can be dangerous as the sudden fall could result in fractures and/or other extensive damage that could further worsen your situation.
Some of the most common causes of blackouts are as follows:
- Abnormalities of heart rhythm
- Heart diseases
- Problems with the blood vessels of the brain
- Mental illnesses or conditions
- Low blood sugar
- Drugs, alcohol, etc.
- Some medication
More severe blackouts are often linked to heart or brain conditions, which could be fatal. When it occurs as a result of heart conditions, it is referred to as a cardiac syncope. A cardiac syncope can occur when the heart beat suddenly slows down or pauses for a longer while, causing a lack of proper blood supply to the head. Treatments for a cardiac syncope can vary depending on its cause of origin and intensity. General treatments can include medication, support garments, pacemakers, etc.
When linked to the problems within the brain, these blackouts are known as neurologic syncopes. This often occurs as a result of neurological conditions such as seizures, strokes, epilepsy, etc. Treatments for a neurologic syncope can vary depending on its cause and intensity, and is administered upon proper consultation and diagnosis.
