The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. [2] Diagnosis is based on the symptoms after ruling out other possible causes. [3] Recovery from a reflex syncope episode happens without specific treatment. [2]
If a seizure happens during the infection itself, the person most likely does not have epilepsy but has "symptomatic seizures" or seizures occurring because of a known injury to the brain. Once the infection is stopped the seizures will stop. Another more common infection is "meningitis", infection of the membranes surrounding the brain. Since ...
[91] [92] A form of an infection with the pork tapeworm (cysticercosis), in the brain, is known as neurocysticercosis, and is the cause of up to half of epilepsy cases in areas of the world where the parasite is common. [72] Epilepsy may also occur after other brain infections such as cerebral malaria, toxoplasmosis, and toxocariasis. [72]
The central ischemic response is triggered by an inadequate supply of oxygenated blood in the brain. [3] Common examples include strokes and transient ischemic attacks. While these conditions often impair consciousness they rarely meet the medical definition of syncope. Vertebrobasilar transient ischemic attacks may produce true syncope as a ...
Each year, six million Americans experience at least one panic attack, according to the Anxiety and Depression Association of America.
The mysteries of the growing brain are myriad—such as why toddlers have quicksilver moods and why 4 years is the magic age they master blunt-tip scissors. But the last few decades of research on ...
Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems. It is primarily performed by highly skilled and specialty trained gastroenterologists.
As for the orgasm connection, oxytocin is produced in the hypothalamus (i.e., the control center of the brain), which is yet another region activated—both in the posterior and anterior—during ...
