Syncope: Understanding Temporary Loss of Consciousness - Causes & Symptoms

The term 'syncope' refers to a temporary loss of consciousness (LOC) caused by a brief interruption of blood flow to the brain. It is commonly known as fainting or passing out. Syncope occurs when the brain is deprived of sufficient oxygen, resulting in a sudden and transient disruption of brain function.

During an episode of syncope, individuals may experience lightheadedness, dizziness, weakness, pallor, nausea, sweating, blurred vision, or tunnel vision prior to losing consciousness. The loss of consciousness typically lasts for a few seconds or minutes, after which the person usually regains awareness spontaneously without any persistent neurological deficits.
