Syncope
Also known as fainting, syncope is a sudden loss of consciousness caused by decreased blood flow to the brain. Recovery occurs within seconds or minutes of fainting. Symptoms before fainting include lightheadedness, blurred vision, sweating, heaviness in lower limbs, giddiness, confusion, yawning and nausea. A person may also have abnormal paleness, a weak pulse and a drop in blood pressure. Diagnostic tests and exams work to establish the root cause of the fainting and may include a head MRI, electroencephalogram, electrocardiogram and blood tests. Treatment depends on the root cause of the fainting. If no serious medical conditions are present in a patient, preventive matters are the best form of treatment.
