A simple febrile seizure is generalized, occurs singularly, and lasts less than 15 minutes. [19] A complex febrile seizure can be focused in an area of the body, occur more than once, and lasts for more than 15 minutes. [19] Febrile seizures affect 2–4% of children in the United States and Western Europe, it is the most common childhood ...
Systemic infection with high fever is a common cause of seizures, especially in children. [3] [25] These are called febrile seizures and occur in 2–5% of children between the ages of six months and five years. [26] [25] Acute infection of the brain, such as encephalitis or meningitis are also causes of seizures. [3]
Episodes of vasovagal syncope are typically recurrent and usually occur when the predisposed person is exposed to a specific trigger. Before losing consciousness, the individual frequently experiences early signs or symptoms such as lightheadedness, nausea, the feeling of being extremely hot or cold (accompanied by sweating), ringing in the ears, an uncomfortable feeling in the heart, fuzzy ...
If fainting spells occur often without a triggering event, syncope may be a sign of an underlying heart disease. [37] In the case where syncope is caused by cardiac disease, the treatment is much more sophisticated than that of vasovagal syncope and may involve pacemakers and implantable cardioverter-defibrillators depending on the precise ...
Reflex anoxic seizures are a particular type of anoxic seizure, most commonly seen in young children in whom an anoxic seizure or syncope is provoked or precipitated by a noxious stimulus (hence "reflex"). Various precipitants have been identified, but the most common is an unexpected bump to the head.
Tilt table testing could provoke fainting or syncope. It is the purpose of the test to provoke these symptoms, in order to aid in diagnosis. [ 4 ] It may not be appropriate, or indeed even possible, to stop the test before fainting occurs, as the drop in blood pressure or pulse rate associated with fainting can come on in seconds.
Reflex seizures can be either generalized or focal seizures or both. [2] However, for any given stimulus there may be a large variation in the kind of elicited seizure. For example, reading epilepsy may cause myoclonic jerks in the jaw or may cause focal seizures in the regions of the brain responsible for reading. [2]
On average, it takes seven years to receive a proper diagnosis. The differential diagnosis of PNES firstly involves ruling out epilepsy as the cause of the seizure episodes, along with other organic causes of non-epileptic seizures, including syncope, migraine, vertigo, anoxia, hypoglycemia, and stroke.
