Blackout
Blackout
A blackout is a temporary loss of consciousness or memory, often caused by a variety of medical, psychological, or environmental factors. Blackouts can be classified into two main types: syncope and amnesia.
Types of Blackouts[edit | edit source]
Syncope[edit | edit source]
Syncope, commonly known as fainting, is a sudden, temporary loss of consciousness usually due to a drop in blood pressure, which reduces blood flow to the brain. Common causes of syncope include dehydration, orthostatic hypotension, and vasovagal response.
Amnesia[edit | edit source]
Amnesia-related blackouts involve a temporary loss of memory, which can be caused by factors such as alcohol intoxication, drug use, head injury, or psychological trauma. There are two main types of amnesia: anterograde amnesia and retrograde amnesia.
