Alcohol can potentiate orthostatic hypotension to the point of syncope. Older adults are more likely to have orthostatic or cardiac syncope. Symptoms include exercise intolerance, exertional syncope (fainting from physical exertion) and sudden death. Evaluation of vasovagal syncope is done with a tilt table test. It is as common or perhaps even more common than vasovagal syncope. Brugada syndrome also commonly presents with syncope secondary to arrhythmia. Neurological signs include confusion, disorientation, visual disturbance, syncope (fainting), and seizures. Blackout may also be referred to as a syncope or fainting. Aortic stenosis presents with repeated episodes of syncope. Cardiac syncope is associated with worse prognosis compared to noncardiac syncope. Affected dogs are at risk of syncope and sudden cardiac death. The name Syncopy derives from "syncope", the medical term for fainting or loss of consciousness. It can sometimes be difficult to distinguish anaphylaxis from asthma, syncope, and panic attacks. There is no specific treatment for micturition syncope. Narcolepsy may present with sudden loss of consciousness similar to syncope.
