Seizure Trained Dogs New Haven CT

Some dogs trained to detect epileptic seizures are actually predicting psychological seizures, rather than true epileptic attacks, new research suggests.

The studies don’t indicate that seizure dogs aren’t performing as trained, but that a percentage are warning their owners of psychologically based seizures, rather than epileptic seizures, explained Orrin Devinsky, director of the Comprehensive Epilepsy Center at New York University.

Specially trained seizure dogs supposedly can pick up on subtle physiological changes in their human companions that can begin up to 45 minutes before an epileptic seizure. The dogs then warn the humans so they can find a safe environment or take precautionary measures.

It’s important to define what kind of seizures these patients have because certain drugs are used to treat epilepsy, while other therapies are for non-epileptic seizures, explained Gregory L. Krauss, an associate professor of neurology at Johns Hopkins University School of Medicine in Baltimore.

Krauss was lead author of one of two papers documenting the phenomenon in the Jan. 23, 2007, issue of Neurology. The two studies looked at a total of seven people who had seizure-response dogs. Most were monitored to detect abnormal electrical activity in the brain of the kind that causes epileptic seizures.

Four of the participants had no abnormal electrical activity during their seizures, and were diagnosed instead with psychogenic non-epileptic seizures.
