Sudden fainting accompanied by incontinence can be due to neurogenic syncope, cardiogenic syncope, or vasovagal syncope. Neurogenic syncope generally refers to sudden fainting caused by conditions such as cerebral arteriosclerosis, cerebral vascular narrowing, cerebral vascular occlusion, transient cerebral ischemia, insufficient blood supply from the vertebrobasilar arteries, cerebral embolism, cerebral hemorrhage, intracranial space-occupying lesions, or cerebral vascular malformations, which can lead to incontinence and, in severe cases, convulsions. Cardiogenic syncope is generally caused by myocardial ischemia, myocardial infarction, arrhythmia, or heart failure, leading to a decrease in cardiac output and resulting secondary cerebral ischemia and hypoxia, which cause loss of consciousness.
