New guideline: Blood test can help determine type of seizure

13.09.2005


Using a blood test to measure the level of the hormone prolactin can help determine, in certain clinical settings, whether an epileptic seizure has occurred, according to a guideline developed by the American Academy of Neurology and published in the September 13, 2005 issue of Neurology. The guideline authors reviewed all of the scientific evidence available on use of the prolactin blood test to diagnose seizures and developed evidence-based recommendations.



The blood test, which must be used within 10 to 20 minutes after a seizure, can identify the types of seizures called generalized tonic-clonic seizures and complex partial seizures in both adults and older children. The level of prolactin in the blood increases after these types of seizures occur.

The release of prolactin from the pituitary gland is controlled by the area of the brain called the hypothalamus. Researchers have hypothesized that epileptic seizures may affect the hypothalamus, altering the release of prolactin.


The test cannot distinguish epileptic seizures from a fainting condition called syncope, because prolactin levels may also increase after syncope, according to guideline authors David K. Chen, MD, Yuen T. So, MD, PhD, and Robert S. Fisher MD, PhD, of Stanford University in Palo Alto, Calif.

The guidelines found that a prolactin test can be useful in differentiating epileptic seizures versus psychogenic seizures, or seizures caused by mental problems.

There was not enough evidence to determine whether the prolactin test is useful in evaluating cases of status epilepticus, repetitive seizures, or neonatal seizures.

The guidelines state that the test is useful as an adjunct test, especially in cases where video EEG (electroencephalography) monitoring is not readily available. Future research needs to be done to determine whether the test is valid for younger children.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
